Restoration of entrance doors. This instruction will help you to repair a metal door Do-it-yourself repair of a metal entrance apartment door

An entrance metal door is one of the most popular options today. A reliable durable product in combination with multi-level modern locks is really capable of ensuring the safety of a home and its inhabitants. But no matter how strong and durable the structure is, over time it will also need to be repaired.

Metal door: features

Its basic structure does not differ from a conventional swing door: door leaf and frame. However, the design of the canvas is different, and the installation is carried out by other methods.

• The sash is a steel profile frame, reinforced with vertical, horizontal or combined stiffeners and sheathed with iron sheets on both sides. The thickness of the sheet depends on the class of the product and ranges from 1 to 5 mm.

Usually the door leaf is finished with some material - from powder painting to sheathing with MDF panels. The finish not only makes the product look attractive, but also protects the steel from corrosion.

• The door frame is also made of steel profiles. It is installed on the anchor in such a way as not to adhere to the doorway, but to grip the walls. If installed correctly, the box can only be removed together with a part of the wall.
• The front door is equipped with locks of varying degrees of complexity and reliability. The latter, as a rule, cannot be repaired.

This entire structure weighs on average about 100 kg. Such a hefty mass and reliability of installation significantly reduces the number of repair work that can be done by hand.

Possible problems

In most cases, problems are typical for entrance doors located outside and exposed to weather factors - sun, rain, snow. It is necessary to repair the entrance apartment structures much less often.

• Locking system - when it comes to simple standard locks, then you can replace them yourself: you just need to choose the appropriate system. If complex, with vertical transoms, you cannot do without the participation of specialists.
• Fittings - hinges, handle, door peephole. Most often, problems arise with the hinges, since the metal sheet is heavy and sags over time.
• Door frame - under the influence of weather factors or as a result of hooliganism, it can change its configuration, its position in the opening. In the latter case, you need to contact professionals, since you will need to restore the doorway and reinstall the frame.
• The canvas is the most reliable part of the entrance structure. Usually it has to be repaired when the finish is damaged.

Loop release

Repair of iron doors is most often associated with a skewed door leaf. At the same time, the sash does not close well, the rubber seal is damaged, which means that the thermal insulation properties are lost. There are several reasons for such problems.

• Sagging of the canvas - over time, under the weight of the sash, the hinges weaken, and the metal door sags.
• Loop wear - even the highest quality fittings wear out over time, which means that the sash ceases to fit snugly to the box when closed.

The outer door hinges cannot be adjusted. If loose or damaged, the hardware must be removed and replaced with a new one. If the hinges are screwed on, then it is not difficult to remove them. If welded, you will have to cut.

Internal hinges are equipped with adjusting screws - upper and lower and central. The sash position is corrected by tightening or loosening the central screw. The tightening screws are used as locks. Manipulations are performed with a 4 mm hex key.

• Skewed door frame - quite often the cause of the problem is the natural shrinkage of the building. If the house is old, it is hardly noticeable, and for several years it does not make itself felt in any way. But since the entrance metal door is a very rigid structure and assumes a rigid fastening, it is the first to become a "victim" of shrinkage.

The situation is corrected by driving wooden wedges under the door frame. In the photo you can see the working moment of such a repair.

Damage to the web

Of course, it is impossible to repair the traces of blows or the destruction of the structure with your own hands, but the defects in the finish are quite possible. Difficulties, as a rule, arise when such a finish is paint - powder or polymer.

If the paneling of the sash is damaged - MDF, leather, wood, then such a defect is very noticeable and is corrected immediately. Accordingly, the door leaf is not endangered. But when scratches or scuffs appear on the paint, measures are not taken immediately, and it often turns out that during this time the steel has time to get covered with rust. In this case, repairs will take longer.

1. The iron sash is removed from the hinges, fittings and seals are dismantled.
2. Rusted areas are brushed and sanded.
3. The surface is degreased, puttyed - it is recommended to use automotive products, and sanded again to achieve an even surface.
4. The canvas is primed with an aerosol primer, after it has set, it is covered with paint. It is advisable to re-sand the surface before applying the second layer.
5. When the paint dries, the seal is again attached to the sash, locks are placed and the canvas is put on the hinges.

In the video, the repair of a metal door is examined in detail.

metal: repair

Metal ones are more reliable than wooden ones, but if necessary, repair them. Metal ones often require the intervention of an experienced craftsman. However, in some cases, you can handle it yourself. First, you need to find the defect or malfunction due to which it began to work poorly.
Reasons for which repairs may be required may be:

• Wear.
• Poor block quality or installation.
• Attempt to open without a key.
• Defective lock.

In addition, the desire to update the appearance may become a reason for repair.

Sometimes you can cope with the repair on your own, but if the problem is serious and professional tools such as a welding machine are required to restore functionality, you will have to rely on the master.

It is also worth noting that not in all cases repair is generally possible - metal is sometimes easier to completely replace than to restore.

If the lock is broken

A failed lock is the most common cause of breakage (see).

Its complete replacement is possible if you find a lock of the same size and design as the old one. But for this it is often necessary to dismantle the inner lining.

If the cylinder lock is broken, first try to replace only the cylinder lock. It can be removed quite simply - you need to unscrew the fixing screw at the end.

If the reason is more serious, or if your door has a complex safe lock or with vertical bolts, it is better not to risk it and call a specialist.

If skewed

The skew is immediately noticeable: it ceases to close well, scratches the threshold, its heat and sound insulation properties deteriorate (see).

What can cause the skew, and in what cases repair is required:

1. A very heavy door. Made of multi-layer thick steel, it is difficult to hold in the desired position even for the highest quality hinges. After several years of operation, it sags and stops closing. It is very difficult to eliminate such a breakdown. You can try to cut the buttonholes and reinstall. But in a couple of years, repairs await you again.
2. Loose hinges. It occurs naturally due to their mechanical wear. Replacing the hinges, if they are not welded, but screwed into specially made holes, is not difficult. The main thing is to find the same ones so that the holes in the cards coincide with the holes in the box.
   

   Advice. You can try not to change the hinges, but to pick up the washers of the required diameter and put them on the pin. Before this, all parts must be lubricated with grease or other means.

3. It will be much more difficult to repair if its distortion was the result of shrinkage of the house, as often happens in block and monolithic new buildings. In such cases, the box itself is warped. But in a private house, you can try to drive a wedge under the base of the box.

If rusted

Rust removal

If it has not been painted or if the paint has peeled off for a long time, it will rust and rot, especially in the lower part. In this case, the repair will not consist in simple staining, but in a whole series of activities.

Prepare materials and tools for repair:

• medium and fine abrasive paper
• metal brush
• solvent
• putty knife
• putty for metal
• primer and paint in spray cans.

Process:

If the lining is worn out

When the appearance of the front door ceases to please you, you should not change it to a new one. This is the case when self-repair will really help you out - after it, they will look like new.

As a rule, the replacement of finishing materials is made for similar elements, but sometimes you can dream up. For example, remove the outer leatherette upholstery and trim with laminate or MDF (see).

The aesthetic component is one of the most common reasons for door repairs. For example, after renovation, the door may not fit into the new interior.

In this case, various methods of decorating the surface of the door leaf are applicable:

• painting
• airbrushing
• facing
• upholstery.

The easiest way to decorate is to paint the door. Moreover, staining can be in the tone of the room or carried out by applying a variety of reproductions and landscapes to the door.

The process is quite simple - an insulator is attached to the door, then a substrate (batting, foam rubber, etc.) is placed, fastened with strips at the end, another layer of insulator is placed, and at the end all layers are covered with a facing material.

The use of an elastic substrate gives the effect of a carriage coupler, as well as the possibility of decorating the surface using false frames, with the help of which an ornamental pattern is placed on the door. Also, the door can be finished with veneer, laminate or similar hard materials.

In this case, an adhesive connection is used. Surfaces finished with laminate are much stronger and more durable than eco-leather and leatherette. Now you are convinced that repairing steel doors is not difficult. Good luck in your endeavors!

Capital metal doors are durable, but over time they break. It is believed that the repair of entrance iron doors is available only to professionals; in reality, an amateur can fix most of the knots on his own. Next, we will analyze common breakdowns and tell you how to repair a metal door with your own hands.

If you have a tool, do-it-yourself repair of entrance metal doors can be done in 1 day.

That in iron doors you can repair yourself

In a standard iron door, you can repair 80% of breakdowns with your own hands. True, here a lot depends on the presence of the necessary tool in the master's arsenal, plus some breakdowns cannot be done alone, since the canvas is heavy and an assistant is needed.

• In the rating of breakdowns, locking mechanisms are in the lead, since you do not need helpers and expensive tools to replace or repair the lock. It all depends on the type of lock, in some cases you can even do without buying new parts.

Often, self-repair of an iron door is possible only in cases where there are no radical violations of the canvas or the supporting structure, if the lock is cut out or the door is torn out along with the box, then you need to call professionals

• The next number is the defects of canopies, the hinges on metal doors experience heavy loads, therefore they need constant attention. Most often, the repair of iron door canopies ends with their adjustment.
• Sometimes the accompanying fittings fail, this includes door handles and a peephole. Often, the repair of these units does not make sense, so they are changed immediately, although there are exceptions.
• All metal doors have an all-welded frame. The closed iron circuit is difficult to break, but there are also 2 weak points here. First, installation errors can be made. Secondly, the box can warp when the house shrinks, but shrinkage processes are usually inherent in new houses.
• External repair of an entrance metal door is related to the accompanying, in other words, you can live with a scratched cladding, it does not affect the functionality, but we will also tell you about how to restore an iron door.

Advice! Starting to work with any specific node, immediately diagnose all the above-described problem points, because it is always easier to identify and repair a breakdown at the initial stage.

When starting to repair steel doors, it is advisable to clearly understand how the structure works

Repair of locks on iron doors

Five types of locking mechanisms can now be installed on entrance metal doors.

1. English cylinder head locks.
2. Lever locks.
3. Crossbar mechanisms.
4. Electromechanical and electronic systems.
5. Combined constipation, consisting of several types of locks.

You can repair only the first 2 positions with your own hands - these are cylinder and lever positions. Crossbar locks are mainly installed on utility rooms, and for the repair of electronic and combined mechanisms, special tools and relevant knowledge are needed.

English Head Cylinder Locks

One of the oldest and at the same time, reliable systems. The power mechanism in such constipation is simple, there is nothing to break there, usually problems arise with the secret heads.

Cylinder heads are non-repairable units, they just change. Fortunately, such a head can be replaced in a few minutes.

Instructions:

• unlock the lock and put the key in the zero position (the position at which the key is removed);
• from the end of the door leaf, directly opposite the keyhole, find the locking screw;
• unscrew the locking screw and remove it completely;

The screw fixing the cylinder head is located opposite the keyhole, it is only there, so it is difficult to confuse

• now you need to try to remove the cylinder head;
• if you cannot remove the head immediately, it means that you need to turn the key again to try to remove the mechanism, inside there are cams, which should be in the zero position, then the head will come out;
• then take a broken head, go to the market and buy the same one;
• installation is carried out in the reverse order, that is, insert the head, screw in the screw and use the doors.

For more than 100 years of existence, designers have invented several models of cylinder heads, all of them are of high quality and reliable, but focused on different purposes. The rules for choosing the most suitable head for your door can be found.

Lever locks

Lever mechanisms are not so versatile, if the lock breaks, then in most cases it is changed. There are 2 options for installing such constipation.

1. In the simplest version, the lock is inserted into the hole at the end of the door leaf and fixed with two or four screws.
2. Sometimes the lock is attached to the box from the inside. In this case, in order to get to the mechanism, you will have to partially or completely dismantle the inner casing of the doors.

Important! There are canvases with so-called crab locks, in which the locking pins are pulled out immediately from 3 or 4 sides along the contour. The lock in such models is connected with pins, so there the repair of a metal door begins with dismantling the internal decorative panel.

With end mounting, the outer strip of the lock is clearly visible, and when the mechanism is embedded from the inside of the box, only the screws are visible, but until access to the lock is open, it is useless to unscrew them, since there are additional latches inside

Lever locks are quite reliable and if the mechanism starts to junk, you should not immediately run to the market for a new one, especially since the price of such locks is solid. First, remove the lock and examine it.

Some of these models can be disassembled, there are several screws on the side around the perimeter that need to be unscrewed, after which the side plate will be removed. Often the cause of breakdown is elementary debris. The lock just needs to be blown out, cleaned and lubricated.

Advice! If the box of the lever lock is riveted tightly, then it is useless to cut the rivets, even if you disassemble the lock and fix the malfunction, it will be problematic to assemble and fix the box cover back.

If the box of the lever lock is assembled with screws, then it makes sense to disassemble it and try to repair it, in half of the cases the problem is eliminated

Repair of hardware for iron doors

The peephole on the front door rarely breaks, unless vandals spoil it. Replacing such accessories is simple, a lock nut is unscrewed from the inside, after which the old peephole is removed, and a new one is put in its place. Much more often the handle breaks or the seals wear out.

How to replace the handle

Handles are of 2 types.

• The handle on the rosette is a separate mechanism not connected in any way with the keyhole.
• The handles on the bar are considered more reliable, here a single metal bar not only holds the handle mechanism, but also covers the keyhole.

In terms of their performance, the handles on the outlet and on the bar are approximately equivalent

To replace the handle on the rosette, you need to unscrew the top decorating ring on both sides of the door leaf. Further, from the side of the room, it is necessary to unscrew the locking screws, after which the structure will be removed.

Rosette handles are mounted in metal doors using two through pins

A doorknob on a plank is more difficult to choose than to install. When choosing, 2 main parameters are taken into account. First, you need to measure the distance between the mounting screws. The second, but no less important parameter is the distance from the handle itself to the keyhole. Details with photos and videos, selection, measurement and installation of the handle on the bar is shown.

Replacing the seals

Repair of entrance iron doors is not only emergency, but also current, intermediate. On any, even the best and most expensive door leaf, there is a system of seals that wear out sooner or later. High-quality gaskets last up to 5 - 7 years, the budget option wears out in 1 - 2 years.

To replace the seal, you need to rip off the old gasket, then clean and degrease the metal. New moldings usually have a self-adhesive backing. The master only needs to pull off the protective strip and glue the seal to the doors or door frame.

Replacement of seals does not require special skills and high qualifications

Steel door awning repair

There are 2 types of canopies installed on home metal doors - simple, such as "dad-mom" and hidden. Both options can be adjusted, but the instructions are different.

Adjusting simple awnings

Now in the domestic sector, more than half of the iron doors are installed on simple and reliable hinges of the "dad-mom" type, they practically do not lend themselves to adjustment, but they rarely break.

The male-female hinges must have technological holes for pumping grease

These canopies have 2 problems, either the lubricant has dried out, or the canvas has sagged under its own weight. In the first case, you just need to pump lubricant there. If the canvas sagged precisely because of the canopies, then the repair will also not be difficult, but third-party help may be needed here.

First, you need to decide on the amount of subsidence. In iron doors, the gap between the leaf and the frame around the perimeter is 3 - 5 mm. When the canvas sags, it starts to cling to the threshold. Here you need to measure how much (relative to the threshold) the canvas has subsided and add another 3 mm to this value.

There are two ways to eliminate subsidence.

• If the door has sagged strongly, then you need to remove it from the awnings and insert a steel ball from the bearing inside the awning.
• If the amount of subsidence does not exceed 5 mm, then a bearing must be put on the canopy pin. These actions must be carried out with all the hinges that are on the doors.

Advice! Both balls and bearings for such canopies are available in any construction market, for purchase you will need to measure the diameter of the rod and the outer diameter of the canopy itself.

When choosing a ball, you need to know the dimensions of the central pin and the depth of the glass, and when choosing a bearing, you need the diameter of the pin and the diameter of the canopy

Adjusting hidden awnings

Another "headache" is the adjustment of hidden awnings on metal doors. If the canopy is of high quality, then there is nothing complicated there. Such designs are regulated by an internal eccentric, which is located in the center. The instruction looks like this.

• First unscrew the hexagon screws around the perimeter.
• Then release the locknut on the eccentric (the eccentric is always in the center).
• Now, by rotating the eccentric to the right or left, adjust the canopy.
• Once the desired position is found, it is necessary to re-tighten the screws around the perimeter and fix the eccentric with a lock nut.

There can be 2, 3 or 4 fixing screws along the perimeter of the canopy, but the adjusting eccentric is always in the center

But there is also such an outlandish thing as Chinese iron doors. The adjustment of these unpredictable structures, as well as other types of canopies for metal doors, is shown in detail and painted with photos and videos.

Repair of a box of iron doors

If there are problems with the box, then it will be difficult to repair metal doors on your own. As already mentioned, the skew of the box occurs either through the fault of the installers, or as a result of the shrinkage of the house.

If the installers are to blame, then the geometry of the box will remain the same, but the frame will begin to "walk", that is, deviate from the vertical in any direction. You can figure this out using the bubble level.

Skewed box can be easily identified with a bubble level

To correct vertical and horizontal deviations, wedges are used, you can make them yourself from wood or buy plastic wedges on the market (the second option is better). Then you drive wedges between the box and the opening in the right place, so you set the frame clearly vertically and horizontally.

Additional anchors are used to fix the box in the correct position. In this case, the old anchors can not be removed, the structure is simply reinforced with new ones.

When leveling the box, it is not necessary to remove the already driven anchors or crutches, it is enough to drive in new ones

Repair of steel doors when the house shrinks is carried out in a more radical way. In this case, the strong metal struts bend as a result of the pressure from above and you need to align them, but first you need to find the center of deformation. To do this, take a sheet of paper and clamping it with a canvas, try to take it out. Where the sheet can be taken out freely, there is a deformation point.

If the rack is squeezed out or in, then take a heavy hammer and align the box through the gasket. If the deformation goes towards the wall, then the box is leveled using wedges.

With a hammer, you can even out the deformation up to 10 mm, if the curvature is greater, then you need to change the box

How to restore attractiveness to doors

The loss of appearance does not affect the operation of the mechanism and the reliability of the structure, but this problem is more noticeable than others, therefore, redecorating iron doors for many owners is more important than, for example, adjusting awnings. There are several options for self-restoration.

• Carriage coupler... This cladding method has existed for about 200 years. In addition to its solid appearance, the upholstery also serves as a powerful insulation. It is quite possible to make such beauty with your own hands, you make a shield, and then attach it to the door. There is a step-by-step instruction on the choice of material and arrangement of the carriage coupler.

A luxurious carriage coupler on metal doors can be equipped with your own hands in 3 - 4 days

• Laminate finish... Laminate flooring is considered an excellent option for self-cladding iron doors. The coating is vandal-proof and quite durable. The only place where laminate flooring cannot be installed is on the street. Instructions for cladding doors with laminate flooring can be found.

If you have a tool, finishing the entrance doors with a laminate is quite accessible to the amateur

• Painting... The simplest and most decent option. The main thing here is to choose high-quality paint, the process itself will take a couple of days.
• MDF cards... You can replace or screw a new MDF card to steel doors in a couple of hours, plus the choice of colors, textures and types of overlays is huge.
• Natural wood... In this case, either a board is usually used, for example, lining, or ready-made wooden boards. The technique of arranging the last three options (painting, MDF cards and natural wood) is described and shown in detail.

Output

Of course, it is not always possible to do the repair of entrance metal doors with your own hands. I talked about the methods that are guaranteed to work. The video in this article shows the most interesting points visually. If you have something to add or have any questions, write in the comments, than I can, I will help.

Entrance doors protect an apartment or a private house from unwanted intrusion of unauthorized persons. Metal models are becoming more and more popular every year, as they have an increased level of safety. However, the repair of metal entrance doors is a rather difficult undertaking. This is due to the complexity of their design. The repair methodology is determined depending on the nature of the breakdown.

Most of the faults arising during the operation of entrance doors can be eliminated without the help of a specialist with your own hands. To do this, you need to familiarize yourself with the rules for the repair of metal structures, which will eliminate errors during this event.

Repair of doors in an apartment or a private house has a certain algorithm. Its features are determined depending on the material of manufacture of the entrance group. However, the elimination of some types of faults is general for all types of door leaves.

Regardless of what material the structure is made of, the first step is always a preliminary inspection. It is necessary to assess an existing malfunction and select the best way to fix it. At this stage, the selection of tools that will be used during the repair is determined, as well as additional materials (if necessary).

Note! To repair a metal door in an apartment or a private house, you cannot use available tools. If it is necessary to completely replace a particular part, it is recommended to select a new device in such a way that it fully corresponds to the broken element in terms of its technical characteristics.

If during the repair of the metal sheet, tools that operate from the mains are used, you need to check their serviceability. Any malfunction of the tool can lead to errors during the repair work. After elimination of defects, it is recommended to take all preventive measures in order to avoid repeated breakdowns. For example, you can mount a door closer that contributes to the smooth movement of the structure.

In the case of contacting specialists, the cost of repair work may be different depending on the complexity. The cost of repairing a door is the main factor to be guided by when choosing a way to troubleshoot a problem.

During operation, the surface of the door with or without cladding wears out. Ultimately, this may lead to the need for restoration of the product. In this case, the canvas should be removed from the hinges and all work should be carried out in a horizontal position - this method will be more convenient.

Repair of metal entrance doors: the most common breakdowns

During the operation of the entrance web, various unfavorable factors affect it. They can be both physical and mechanical. There are the most vulnerable elements that make up the door structure, which are most often subject to wear and tear and various breakdowns:

• lock;
• fittings (hinges, handles, peephole);
• door frame;
• the surface of the canvas;
• platbands.

The most common breakdown today is the failure of the locking mechanism of the steel door lock. Repair of this device is possible, but it is extremely difficult to carry out it yourself. Often a complete replacement of the lock is required, which is also not an easy undertaking. For a person who has no experience in this business, dismantling an old device and inserting a new one can be a difficult task.

Hardware failure is a common problem. In this case, it is quite simple to carry out an independent repair, but you must take into account the degree of complexity of the problem. For example, fixing a door closer that restricts door opening can be difficult. Most often, closers fail due to curvature or in the event of an oil leak.

Useful information! Door frame problems most often arise due to improper installation. A very important point is the correct selection of the weight of the canvas. Some boxes change their geometry due to the fact that the door is too heavy.

A jammed lock is a common problem. The reason for this is the failure of the core of the mechanism - the secret. Moreover, the door can jam at the most inopportune moment, for example, when you are outside the living quarters. The door leaf is subject to wear and tear, which leads to the loss of its original appearance. The outer surface of a metal door is most often sheathed with decorative facing materials or covered with paints and varnishes, which make it possible to increase its operational life.

When using a door, mechanical factors very often influence its decorative elements. Platbands are most susceptible to damage, so replacing them is a fairly common event. It is worth noting that each malfunction primarily occurs due to improper operation of the door structure.

What tools are used to repair metal doors

As mentioned above, the toolkit is selected depending on the reason for the breakdown. The complexity of restoring a particular structural element is taken into account when choosing the appropriate devices. Consider what tools are used during the troubleshooting of various problems in the operation of the entrance canvases.

When the door frame is skewed, the building level is an indispensable tool. Its use allows you to adjust and fix the structure in the desired position. A measuring tape is also used quite often when correcting geometric problems of entrance structures.

What other tools are used when repairing entrance doors in an apartment and a private house? From electronic equipment, a screwdriver is most often used. Self-tapping screws are needed to fix the door frame and hinges. Often there is a need to eliminate voids between the door frame and the opening. In this case, you cannot do without polyurethane foam.

To fix some elements of decorative sheathing, special glue is used. A regular pencil is used for marking. In addition, you may need hexagons and a construction knife.

Useful information! To eliminate the squeak, you should use a special lubricant for the hinges or ordinary machine oil.

All of the above tools are used to repair metal entrance structures. If it becomes necessary to restore an iron door, additional materials used as cladding may come in handy.

Front door lock repair: the most common causes of breakdowns

There are quite a few reasons for the breakage of the lock installed in the front door. The possibility of a problem will be higher if the device is not of good quality. Improper use also increases the likelihood of breakage. Let's consider the most common causes that lead to malfunctions.

The tongue is not fixed. As a rule, the reason for this is the insufficient dimensions of the mating hole cut in the door frame. In some cases, problems associated with closing the door may arise due to its skew. In the first case, to repair the door lock, the tongue itself is bored. And you can also simply shift the mating hole so that it is located more accurately in relation to the lock tongue. The second problem is eliminated by adjusting the position of the door frame and door leaf.

The door opens with difficulty. The most likely reason for such a problem may be that the lock was skewed during operation. During the preliminary inspection of the door, it is recommended to pay attention to the flatness of the door. This problem is solved by repairing the front door lock in the apartment. This measure involves adjusting the position of the shut-off device.

Another common problem is a key jammed in the locking device. It is worth noting that the owners of metal doors most often face such a problem. In this case, two reasons are possible: debris falling into the mechanism and displacement of individual elements of the device. In order to repair the lock of the entrance iron door, you will need to dismantle it, disassemble and repair it. Next, you need to lubricate its internal elements, assemble them and install them back.

The lock is jammed. The main reason for such a problem is the state of the locking device larva. It is quite difficult to repair the front door larva on your own. Therefore, as a rule, such a problem is solved by replacing the old mechanism with a new secret.

Useful information! Before you start repairing the castle, you need to determine its type and pay attention to the photos that will help you understand the structure of the mechanism. Most often, entrance doors are equipped with cylindrical safety devices. Lever locks are in second place.

Iron door lock repair: how to replace the cylindrical mechanism

If the core of the lock is out of order, you will need to replace it yourself. Before purchasing a new larva, you need to determine its type. The core can be cylindrical or leveled. You should know how to replace the cylinder lock yourself.

First of all, it is necessary to dismantle the armor plate - the protective plate of the locking mechanism. Then you need to unscrew the screw at the end of the door. It is a fixing element. Repair of the door lock cylinder must be carried out as carefully as possible, since there is a possibility of damage to the locking mechanism.

After removing the retaining screw, the cylinder must be removed. Installing a new core is fairly straightforward. It is inserted into the place of the old secret, after which the same manipulations are performed as described above, only in reverse order.

It is worth remembering that the new core must be identical to the broken lock. Otherwise, this element cannot be replaced. In some situations, a complete replacement of the lock may be required. Do-it-yourself door repair is recommended without haste. If, after installing a new larva, it was not possible to fix the problem, it is necessary to re-inspect, which will determine the nature of the problem more accurately.

How to repair a lever lock with your own hands

It is not possible to repair the front door lock cylinder in a lever lock. This is due to the design features of this locking mechanism. If the core of the lever lock fails, there is only one solution - its complete replacement. Before starting work, it is recommended to study the step-by-step instructions for this process.

The first stage of replacing the lever mechanism involves the displacement of the crossbars (by means of a key). To replace this type of lock, the door must be opened. Then you need to unscrew the screws that fix the mechanism. They are located on the end surface of the door leaf.

At the next stage, the body of the locking device is removed and replaced with a new mechanism. After that, you need to fix the new lever lock with self-tapping screws (at the end).

Note! Many companies produce canvases that simplify apartment renovation. They are equipped with a mechanism that can be repaired by recoding the levers. This option is much simpler than a complete replacement of the locking device.

It should be said that other types of mechanisms are not highly reliable. Some of them cannot be replaced, since it is impossible to find parts suitable for them on sale. For example, cruciform larvae belong to these mechanisms. In this case, the cost of repairing the front door door lock increases, since the device must be completely replaced. If such an element fails, the best solution is to install a new lock.

Repair of the entrance metal door in the apartment: how to eliminate squeak

One of the most well-known problems associated with operating iron front doors is creaking. At the same time, this problem has the simplest solution. It is very easy to repair a canvas that makes creaking sounds when opening and closing.

The reason for this problem is the friction that is generated when the parts of the canopy move. To eliminate unpleasant sounds, it is enough to lubricate the working parts of the structure with machine oil. How to properly repair the entrance iron door to the apartment in this case?

The first step is to find a stand that must be placed under the door. Any solid object (for example, a shovel handle) can handle the functions of a wedge. A lever should be created with which it will be possible to slightly raise the door, which is on the hinges.

Next, you need to apply machine oil or any other suitable lubricant in the slots near the hinge pins. After that, it remains only to lower the door back. This procedure must be carried out carefully. Do not rush, otherwise the door may fly off its hinges.

Repair of an entrance iron door: how to adjust the web

Another common problem associated with the operation of the front door is skew. To solve this problem, it is necessary to adjust the design. The alignment process involves adjusting the hinges, the displacement of which often causes the web to sag. In addition, adjustment of other fittings (lock, handle, etc.) is often required.

The main tool for leveling the door is the building level. The modern market has a large assortment of budget designs. Chinese entrance metal doors are very popular due to their low cost. However, the quality of such products leaves much to be desired. It is these entrance doors that are most often skewed.

Useful information! If necessary, you can purchase a modern design that has built-in mechanisms that allow you to adjust the position of the web.

The price of entrance street metal doors installed in the apartment is determined depending on the dimensions of the product, as well as the build quality. Experts recommend purchasing canvases belonging to the middle price segment.

When carrying out adjustment work, you must be very careful, as incorrect actions can lead to new problems. Each breakdown has its own solution to the problem. Before starting work, you need to find out the reason for the malfunctioning of the structure and study the instructions for eliminating this type of malfunction.

Adjustment of internal hinges on installed metal entrance doors

Internal loops are also called hidden loops. Such elements can be found on aluminum and steel sheets. These parts are not visible from the outside, so the door on which they are installed is more difficult to open. It is important to remember that there are three options for adjusting the inner hinges, each with a different direction of adjustment.

When is hidden door hinge corrected? The need for customization appears when the doors lose their functionality. There are two common problems with hinges. The first of these is the touching of the canvas with the canvas. In the second type of malfunction, a rather large gap forms between the closed door and the door frame.

Often, many owners, faced with similar difficulties, begin to think about replacing the entrance metal door. However, all of these problems are fairly easy to fix. It is enough to adjust the web. For this operation, you will need to prepare a 4 mm Allen key. When performing this work, it is recommended to follow the instructions below.

First of all, you need to fully open the canvas. This will allow maximum access to the hinge screws to be adjusted. If the leaf touches the door frame, then you need to tighten the screws. In turn, the presence of a gap between the bow and the canvas, on the contrary, requires the weakening of the fastening elements of the hinges.

The cost of repairing entrance iron doors, which have lost the adjustment of the hinges, is small. However, in this case, you can do all the work yourself. There are some nuances worth paying attention to. For example, if the door leaf touches the door from below, then you will need to tighten the upper hinges.

Note! During adjustment, you need to get to the central mount that fixes the hinges. To do this, first the extreme fasteners are loosened, and then the recessed ones. Hidden fixing parts can be cleaned of dust and lubricated. Next, the fixing parts are screwed in in the reverse order.

The cost of repairing the lock of entrance metal doors, as well as hinges and other fittings, can vary greatly depending on the nature of the malfunction. Raising or lowering the door a little is quite simple. To do this, tighten the upper and loosen the lower screw (to lower the level of the leaf) or carry out the reverse manipulation, which allows the door to be raised.

What to do if metal entrance doors to a house or apartment have sagged

Shrinkage of an entrance door made of steel or aluminum occurs due to its active use. Of course, the material from which the canvas is made affects the possibility of shrinkage. High-quality doors have a large margin of safety, and also have more reliable fittings.

The most likely cause of this problem is loosening of the hinges. Deformation of the butt can also lead to a functional defect of this type. Sagging caused by loops is easy to fix. To do this, tighten the bolts securing the elements of the door leaf fittings.

Do not forget that even the best metal entrance doors can sag over time. Tightening the hinge bolts may not always fix this problem. In the event that the door is not aligned, it is recommended to perform other actions.

Before starting to correct this defect, it is very important to conduct a preliminary inspection of the structure. An important point is the comparison of the weight of the web and the strength of the loops. In order to correct the sagging of the entrance structure, in some cases it is necessary to add another hinge, since 2 elements may not support the weight of the door. When installing additional fasteners, it is necessary to step back 15-20 cm from the upper hinge.

Quite often, there are other problems in which difficulties arise when closing the door. In this case, the situation can be corrected both by tightening the hinges and by replacing the hinged cladding elements. The reason may be hidden in other fittings as well. For example, sometimes a door handle needs to be repaired and the problem will go away.

And, finally, another reason for the sagging of the door can be the deformation of the door. When choosing a new door leaf, it is necessary to choose the most suitable and reliable frame that can resist the weight of the door. The skew of the bow can be eliminated quite simply: using a level, you need to align the structure. It is important to remember that before starting work to eliminate the skew, you need to remove the door leaf.

How to fix the skew of the door frame yourself: step by step instructions

Determining the problem of skewing the door structure is quite simple. Such a malfunction is accompanied by a decrease in functionality and difficulties arising when opening and closing the door leaf. If the bow is skewed, it is required to align it. If necessary, the structure is strengthened, which avoids repeated distortion in the future.

In this case, the cost of repairing a metal entrance door is approximately 2000 rubles. You can save this amount by self-correcting the defect. First of all, in order to carry out repairs with your own hands, you should determine the cause of the skew.

What factors can cause this problem to occur?

Large mass of the door. Metal sheets are of considerable weight. Quite often, the massiveness of the canvas contributes to a change in the geometry of the door frame. The sequence of actions in this case depends on the degree of curvature of the palate. The skew that has arisen at the initial stage is much easier to remove. To do this, you just need to tighten the loose loops in the structure.

Note! During the repair of entrance metal doors with your own hands, you need to understand that if the hinges have lost their original shape, then they must be replaced.

Loop wear. It occurs as a result of long-term and constant operation of the structure. It is quite simple to fix this problem - you need to replace parts that do not cope with their direct functions. However, there are designs in which the hinges are welded to the door leaf. In this case, their replacement becomes more difficult, since it becomes necessary to trim the old hinged elements.

Deformation of the butt. This defect is also quite common. The problem is solved in the following way: spacer wedges are inserted under the base of the box, after which it is necessary to strengthen the structure with cement or any other reliable material. The danger of this or that complexity requiring repair depends primarily on the cost of the entrance metal door, which determines the quality of its execution.

Separately, it should be said that the reason for the problematic closure of the web can be the wear of the rubber seal. Replacing it is very easy. Any person who does not have special construction knowledge and skills can cope with this task.

Front door restoration: how to deal with metal corrosion

After it is recommended to paint. A layer of paint protects the door from the damaging effects of corrosion. If you neglect this rule, then over time, rust will appear on the outer surface of the door. The most susceptible to corrosion are metal structures that are installed in private houses, since they have direct access to the street.

The most vulnerable area where rust occurs most often is the lower part of the canvas. The solution to this problem is to restore the metal door. Let's consider the algorithm of actions that should be performed in this case. First, you need to prepare the appropriate materials that will allow you to independently perform the restoration of the canvas. These include:

• metal brush (to remove rust);
• brushes;
• primer;
• dye;
• solvent.

After purchasing the necessary tools and materials, you need to prepare the door leaf for restoration. For this, the hardware is dismantled, as well as the rubber sealing elements and the protection that protects the inner lining.

The next stage of restoration of an entrance metal door is the removal of rust with a metal brush. Together with it, the old coating is removed (if any). Next, you need to sand the surface and degrease it. These manipulations will prepare the canvas for painting.

Note! Some areas of the metal sheet can be severely damaged by rust. In this case, it may be necessary to putty the surface.

Then a primer is applied to the metal sheet. After that, you need to wait a while for the substance to solidify. Then the door is painted. Before starting to paint, it is recommended to spread a plastic wrap on the floor to protect its surface from drops of enamel. The coloring composition must be applied in 2 layers. At the end of the work, the fittings dismantled at the preparatory stage are installed in place.

Iron door repair: how to repair the sheathing of the canvas

Decorative elements of metal entrance structures often break or simply wear out. If desired, it is quite easy to replace them with new facing agents. Most often, the following materials are used for facing the entrance web:

• leatherette;
• laminate;
• MDF panels.

Each of the above materials has its own characteristics, respectively, and the options for fixing them are different. The cost of repairing entrance iron doors depends on the price of the material with which the surface of the leaf will be faced. To replace the old door trim with your own hands, leatherette is most often chosen. This is due to the fact that it is easiest to revet the door with such material.

One of the most presentable options for facing the entrance structure is artificial leather. The main disadvantage of such cladding is the fact that it wears out very quickly and loses its decorative qualities. In addition, artificial leather is quite expensive.

The maximum protection of the metal structure from adverse environmental factors is provided by a special powder coating. However, it is impossible to apply it with your own hands, since it requires the use of specialized equipment.

Panels made of MDF are a universal option. The cost of repairing an entrance metal door made with this material is the lowest (except for the usual paint). In addition, it should be noted that MDF panels are easy to assemble. Thus, this option is best suited for organizing do-it-yourself plating.

Note! For cladding a metal door, it is not necessary to use materials that need fixing. To save time and effort, you can simply cover such a canvas with paint.

Care must be taken when facing a metal sheet. Before starting work, it is recommended to complete a diagram that includes the dimensions of all elements that will be installed on the door, and follow it. This will eliminate even the smallest installation errors.

Repair of the door handle of an entrance metal door

The doorknob is one of the most prone to breakage in the door structure. In order to repair this part related to fittings, it is necessary to correctly diagnose the nature of the defect. There are several common problems encountered during the operation of this element.

Some breakdowns that lead to the need to repair the front door handle can be identified without disassembling the structure. For example, it very often happens that one end of the spring of this hardware element flies out of the fixing point. It is very easy to determine such a malfunction, since the door handle in this case does not return to its original position after it is turned.

Correcting the problem caused by changing the position of the spring is quite simple. To do this, you need to pick it up and return it to its place. If the spring breaks, the repair will not bring any results. In this case, the most suitable solution is to replace this piece of hardware.

Before you buy a new pen, you need to pay attention to one important point. The holes in the strip, which is intended for fixing, must correspond to the slots on the door leaf. There are other breakdowns that require repair of the metal door handle. Another common problem is the problem with the tongue, which does not move when the handle is turned and does not fall into the desired opening.

How to Repair a Doorknob: Static Tongue

Most often, the tongue does not move due to wear on the handle, which looses out during use. It should be noted that this problem most often occurs in products made from soft alloys, since they are more susceptible to deformation and wear. The absence of displacement of the tongue indicates the flaring of the edges of the door handle groove. There are two ways to eliminate such a breakdown.

The first method to repair the handle of an entrance metal door is temporary. It involves sealing the gap between the "square" and the groove located in the handle. The second method is the most correct and requires a complete replacement of the part.

Another reason for the static door handle tongue is damage to the pin. In inexpensive locks, this element is made of soft alloys, which wear out very quickly and fail. To fix this problem, you need to purchase a new pin and replace the old one.

Useful information! In some cases, it may be necessary to adjust the size of the pin, which is done by cutting and turning.

Repairing hardware requires care. If necessary, you can always seek help from a qualified technician. The prices for repairing locks of entrance metal doors, as well as handles, differ depending on the nature of the breakdown and the complexity of its elimination.

Do-it-yourself door handle repair: part loss

There is another breakdown of the door handle, which is manifested by its falling out. It is important to remember that in this case the problem lies in fixation, so there is no damage to the device itself. The cause of the door handle falling out is the weakening of the retaining element (ring) or its destruction.

As a rule, such a malfunction occurs when the quality of the component parts of the web is low. It is not recommended to buy metal entrance doors, the price of which is too low, as this most often indicates poor quality products.

The most problematic outcome is the collapse of the retainer ring. In this case, the mechanism cannot be repaired. In turn, when loosening the locking element, you must try to tighten it. This should fix the situation. Sometimes there may be problems with the tightening of the ring. For example, if it is made of steel, which is highly durable and springy.

Repair of the apartment door lock, communicating with the handle, is best entrusted to professionals. Self-correction of the situation can lead to even more serious damage. In order to reduce the possibility of a malfunction, it is recommended to carry out preventive inspections of the fittings and their lubrication. This will extend the service life of door handles, locks and other parts.

Insulation of an entrance metal doordo it yourself

Metal sheets are highly durable, but they do not cope well with the thermal insulation function. Metal is a thermal conductor, so doors made of this material heat up and cool down very quickly. This problem can be solved by mounting the heat insulator on the canvas.

Currently, there are quite a few insulators that differ in their composition and structure. The materials that are used to insulate door structures can be easily purchased at any building supermarket, on the market, or you can place an order for them via the Internet. It is worth noting that some canvases especially need to be insulated. These include all metal doors that are installed in private houses and have direct access to the street.

The price of entrance metal insulated doors may be different. The cheapest models cost about 10 thousand rubles. The cost of more expensive structures varies from 20 to 30 thousand rubles. There are also more expensive models, but their purchase is not advisable in most cases.

Note! The door frame is insulated using polyurethane foam (standard version) and special sealing compounds. It is important to remember that proper thermal insulation requires sealing all voids between the door frame and the opening.

Insulation of an entrance metal door: stages of work

The sequence of works on thermal insulation of the entrance web primarily depends on its design features. For example, modern metal doors are insulated with an internal method. Metal panels in this design are fixed to the base by means of screws.

The process itself is not very complicated. Everyone can do it with their own hands, but you must follow the instructions. First, you need to remove the metal sheet from the hinges and put it on a horizontal work surface. Next, you need to unscrew the screws securing the metal panels and remove them. There are empty cells inside the door that need to be measured. Insulation will fit into them.

The insulated entrance metal door does not freeze. And also, condensation does not form on it (due to the temperature difference). This is a very important point, since moisture contributes to the corrosive destruction of the door leaf.

After taking measurements, it is required to cut the insulation, which can be mineral wool or foam, into the required segments. Do not forget that you will need to cut out the areas in which the door lock and peephole are located.

To fix the insulation on the inner surface of the door leaf, liquid nails are most often used. The remaining voids can be filled with regular construction foam. After finishing work, you need to assemble the door and put it back on the hinges. This insulation option is suitable for new structures that are fixed to the base with screws.

The price of insulated metal street entrance doors, which are of good quality, is quite high. Therefore, self-installation of heat-insulating material is an excellent solution to increase the functionality and service life of the canvas.

Repair of a metal sheet installed at the entrance to a private house or apartment, first of all, takes into account the determination of the cause of the breakdown. Some faults can be repaired in minutes. Of course, you need to understand the general principles of metal door construction. It is worth saying that if necessary, you can always contact a specialist who will quickly fix the problem and also provide a guarantee.

More than 70% of the installed entrance doors are metal. This is logical, since 1-2 mm. metal will provide more reliable protection from intruders than wood or plastic. But despite the reliability of the structure, sooner or later it will be necessary to repair metal doors - their parts also become unusable, and this happens for many reasons.

Despite some differences, the repair of aluminum doors is done in approximately the same cases as iron ones. The main causes of breakdowns include:

• Natural aging of the door leaf (metal rusts and oxidizes if you do not monitor it for a long time);
• Buying a cheap door from low-quality raw materials (Chinese ones are completely made from secondary raw materials at a cost of 2-3 thousand rubles);
• Incorrect installation (distortions of the canvas, a falling door lock and a loose seal - and this is only part of the problems that can arise if the master's hands are in the wrong position);
• An attempt to break into from the outside using lock picks or a heavy tool (damage depends on the success of breaking);
• Broken door lock;
• Change of the front of the door when it is worn out.

Any repair of aluminum doors differs in the degree of complexity, in some cases a screwdriver is enough for repairs, but sometimes you cannot do without a welding machine and a hammer drill.

Let's take a closer look at the types of repair of entrance metal doors.

Broken door lock

The door lock is designed for 7-15 thousand openings and closings, subject to careful operation and regular lubrication. However, in practice, the door lock is not lubricated at all, and the opening process takes place with a piercing creak, which, of course, in no case should be. In this way, the lock of the entrance door fully fulfills its resource after 5-7 years of operation. The main types of door lock repair are as follows:

1. Cylinder lock. To replace the cylinder lock face, it is necessary to unscrew the support screw on the end part of the door leaf. Then insert the key from the inside and turn it in order to remove the face of the lock. The new mask must fully comply with the design features of the lock; it is installed as easily as it is removed. To replace the entire door lock, you just need to unscrew it from the door fasteners and install a new lock in the same way, you may need to disassemble the casing, it all depends on the number of pins and the individual characteristics of the door;

1. Leveler castle. Replacing the lever lock is carried out in the same way as the cylinder lock, except that, in addition to removing the mask, it is possible to recode the lever to a new key.

Skewed entrance doors

Repair of steel doors is often required due to their distortion, which creates many inconveniences for residents in the apartment, because the door no longer fits tightly, and cold air, noise from the entrance and even the mounting of intruders pass through the gap.

Most often, misalignment or worn hinges are to blame. It is the hinges that account for the entire load of the door leaf, and this is approximately 50-100 kg. moving weight. The manufacturer can save on the quality of the hinges by installing cheap analogs.

To fix the skew problem, it is enough to change the hinges. How to do it? Well, if the hinges are simply screwed to the door leaf, then you just need to unscrew them and pick up new ones according to the diameter of the fastening hole. It is not very good if the hinges are welded by welding, then it is necessary to remove the door from the hinges, cut off the old hinges with a grinder and weld on new, possibly more reliable hinges. It is worth paying attention to the calculations and geometry of the door, otherwise you will have to cut it off and weld it again many times in order to choose the angle of inclination and length of the new hinges.

The repair of aluminum doors, despite their lightness, may be needed by the happy owners of an apartment in a new building. Many of them noticed how their door gradually warps, it's all about the shrinkage of the whole house, which takes place the first 2-3 years after the commissioning of the object. In this case, it is useless to change the hinges; a complete replacement of the door leaf, or its manual adjustment, will be required. In some cases, you can't even do without a grinder and a welding machine.

Rust on the door leaf

Usually, in the production of metal entrance doors, their surface is coated with a special compound that reliably protects the metal from corrosion, however, the protective layer becomes thinner over time, and many manufacturers even consider the anti-corrosion coating unnecessary and give the customer the privilege of applying it.

Doors repair is carried out in the following stages:

• It is necessary to assemble an abrasive repair kit (coarse-grained, medium-grained and fine-grained skin, iron brush, solvent, spatula, metal putty, primer, paint agent, whether it is a can or another form of paint);
• First of all, all the fittings are removed from the entrance doors, including its inner lining;
• Then all coarse rust is removed with a metal brush, and the places of corrosion are rubbed alternately with coarse-grained, medium-grained and fine-grained sandpaper, you can use a grinding machine;
• The canvas is degreased with a solvent;
• Problematic areas must be putty with a special putty for metal, about the same putty is used in car body repair;
• Then the door is covered with a primer and, after it dries, it is sanded again with fine-grained sandpaper;
• In conclusion, the door leaf is covered with paint, it is advisable to cover the door with anti-corrosion paint in 2-4 layers, avoiding smudges and stains.

Plating repair

Not only metal wears out, but also its skin, and, often, the skin wears out much faster. How to solve this problem? It all depends on the type of cladding used:

• Wear of the iron sheet (the problem is solved by painting);
• Upholstery with artificial leather (beauty and enthusiastic sighs of envious people are guaranteed, but the material is not cheap, besides, leather wears out quickly and special skills are required to work with it;
• The use of laminate (practical and very beautiful, but the price of the issue can scare away the buyer);

• Powder spraying (special spraying up to 0.2 mm thick. To create an insurmountable barrier between the external environment and the metal layer, it is impossible to apply such a coating at home);
• MDF panels (MDF panels will last much longer than leather and ordinary wood, you can choose any color to choose from);
• Sheathing of an iron door with natural wood (carved wood of valuable species, treated with varnish and an anti-corrosion compound is an expensive and durable coating).
