Repair of the entrance and interior doors. Repair of entrance metal doors How to repair an entrance iron door

metal: repair

Metal is more reliable than wood, but if necessary, repair them. Metal often require the intervention of an experienced craftsman. However, in some cases, you can manage on your own. First you need to find the defect or malfunction due to which it began to work poorly.
Reasons for a repair may be:

• Wear.
• Poor quality of the unit or its installation.
• Attempted opening without a key.
• Faulty lock.

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

Sometimes you can handle 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 ones are sometimes easier to completely replace than to restore.

If the lock is broken

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

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

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

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

If warped

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

What can cause skew, and in what cases will repair be required:

1. Very heavy door. It is difficult to keep even the highest quality hinges from multi-layered thick steel. 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 hinges and reinstall. But in a couple of years, repairs will be waiting for you again.
2. Loosening loops. 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 match the holes in the box.
   

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

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

If rusted

Rust cleaning

If it has not been painted or if the paint has peeled off it for a long time, it will rust and rot, especially at the bottom. In this case, the repair will not consist in simple painting, but in a number of activities.

Prepare materials and tools for repair:

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

Process:

If the cladding is worn

When the appearance of the front door ceases to please you, you should not change it for 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 carried out with similar elements, but sometimes you can dream up. For example, remove the outer upholstery from leatherette and finish with laminate or MDF (see).

The aesthetic component is one of the most common reasons for door repair. For example, after the repair, 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
• lining
• 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 various 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 planks at the end, another layer of insulator is placed, and at the end all layers are covered with facing material.

The use of an elastic substrate gives the effect of a carriage tie, as well as the possibility of decorating the surface using false rails, 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, adhesive bonding is used. Surfaces finished with laminate are much stronger and more wear-resistant compared to eco-leather and leatherette. Now you are convinced that repairing steel doors is not a difficult task. Good luck in your endeavors!

More than 70% of installed entrance doors are metal. This is logical, since 1-2 mm. metal will provide more reliable protection against intruders than wood or plastic. But despite the reliability of the design, 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, aluminum doors are repaired in approximately the same cases as iron doors. The main causes of breakdowns include:

• Natural aging of the door leaf (metal rusts and oxidizes if left unattended for a long time);
• Buying a cheap door from low-quality raw materials (Chinese ones are completely made from recycled 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 not positioned correctly);
• Attempted hacking from the outside with the help of master keys or a heavy tool (damage depends on the success of the hacking);
• Breakage of the door lock;
• Change of a door facade at its wear.

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

Let us consider in more detail 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, should never happen. Thus, the lock of the entrance doors fully works out its resource after 5-7 years of operation. The main types of door lock repair are as follows:

1. Cylinder lock. To replace the face of the cylinder lock, 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 lock face. The new face must fully comply with the design features of the castle, it is installed as simply 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 skin, it all depends on the number of pins and the individual characteristics of the door;

1. Level lock. The replacement of a lever lock occurs in the same way as a cylinder lock, except that, in addition to removing the mask, it is possible to recode the levers to a new key.

Skewed entrance doors

Repair of steel doors is often required due to their distortion, which creates a lot of inconvenience 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 is caused by incorrectly installed or worn hinges. It is on the hinges that the entire load of the door leaf falls, and this is approximately 50-100 kg. moving weight. The manufacturer can save on the quality of the loops by installing cheap analogues.

To fix the skew problem, just 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 mounting 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 new, possibly more reliable hinges. It is worth paying attention to the calculations and geometry of the door, otherwise you will have to cut and weld again many times in order to choose the angle of inclination and the length of the new hinges.

Repair of aluminum doors, despite their lightness, may be necessary for 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 will be required, or its manual adjustment. In some cases, you can’t even do without a grinder and a welding machine.

Rust on door panel

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

Door repair is carried out in the following stages:

• It is necessary to assemble a repair and abrasive set (coarse-grained, medium-grained and fine-grained sandpaper, iron brush, solvent, spatula, metal putty, primer, coloring agent, whether it be a spray can or another form of paint);
• First of all, all fittings are removed from the entrance doors, including its inner lining;
• Then all large rust is removed with a metal brush, and the corrosion sites are rubbed alternately with coarse-grained, medium-grained and fine-grained sandpaper, you can use a grinder;
• The canvas is degreased with a solvent;
• Problem areas must be puttied with a special putty for metal, approximately the same putty is used in car body repairs;
• Then the door is coated with a primer and, after it dries, again sanded with a fine-grained sandpaper;
• In conclusion, the door leaf is covered with paint, it is desirable to cover the door with anti-corrosion paint in 2-4 layers, avoiding smudges and streaks.

How to fix installation defects, in the following video:

Cladding repair

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

• Depreciation 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 may scare away the buyer);

• Powder coating (special coating 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 anti-corrosion composition is an expensive and durable coating).

The entrance to an apartment, house, cottage is protected by a metal sheet, which is regularly exposed to different temperatures, physical loads due to the operation process. Over time, the locking structure breaks down. Do-it-yourself repair of entrance doors is easy.

Breakage of elements of the door structure - a consequence of:

• unprofessional installation;
• incorrect operation;
• influence of time;
• exposure to natural factors such as snow, rain, sun;
• the use of physical force.

In the door structure, the following elements become unusable:

• locking mechanism;
• platbands;
• accessories;
• canvas;
• box.

Entrance doors - a reliable design, but even the most durable thing breaks down over time.

Door panel problem

The front side of the protective structure, as well as the inner side, is affected by many factors - cold, heat, ultraviolet rays. Problems with the canvas arise in such situations:

1. Incorrect installation. You can fix it by contacting the experts.
2. Impact of natural factors. To eliminate the consequences, you will need a lot of tools and materials. The complexity of the repair depends on the type of problem.
3. Discrepancy between the mass of the web and the holding force of the fasteners.
4. Box twist.
5. Detachment of finishing material.
6. Damage to the protective layer or its absence.

Let's see how to troubleshoot.

The problem with the box

Warping of the door frame, sprinkling of the protective layer are common breakdowns. The cause of the problems is improper installation, the use of physical force. You can correct the skew by substituting a wedge under the bottom of the box. To restore the protective layer, it is necessary to clean the damaged area, treat with a primer, and paint.

Lock problem

The locking mechanism fails the fastest, especially if it is of poor quality. There are many reasons for the occurrence of breakdowns - debris inside, improper use, distortion of the door structure.

The complexity of installation, repair of the lock depends on the design of the front door. Among the popular types are level, cylinder. Their structure is simple, so carrying out repair work does not require calling a master.

Common lock failures:

1. Jamming of the mechanism occurs when there is a malfunction in the core. To fix the problem, lubricate the inside with machine oil. If the lock is still stuck, it should be replaced.
2. The tongue is not fixed in the correct position. The problem arises due to a mismatch in the dimensions of the reciprocal hole in the box or displacement due to skew. To fix it, it is enough to cut the notch, substitute a wedge under the door frame.
3. Complicated opening of the sash is the result of a skewed lock. When inspecting the structure, you need to make sure that the boat is even. Eliminate inconvenience by adjusting the position of the lock.
4. Jamming of the key is a consequence of the displacement of the core elements, the ingress of debris into, unlubricated rubbing parts. The problem will disappear after core cleaning, alignment, lubrication.

Problem with opening

The problem is caused by incorrect installation. If the finishing material falls off, the door frame falls out, then the entire structure will have to be removed. Only after careful processing of the opening, fitting to the dimensions, can it be put in place.

What can you fix yourself?

Calling a master is an expensive pleasure, but sometimes you can’t do without it. When the problem is minor, you can fix it yourself. With your own hands you can:

• replace, repair the lock;
• restore upholstery;
• eliminate distortion;
• replace accessories;
• to eliminate the centers of corrosion.

Features of door repair

Restoring the performance of a door structure is a laborious job, but anyone can handle it. A preliminary inspection of the canvas, hinges, lock, box will help determine the nature of the breakdown. It is necessary to prepare tools, materials, new parts, if necessary.

Input

Home protection should be reliable, but over time, any things wear out. Repair of entrance doors in the apartment is possible with a minimum set of tools. The door lock often breaks - it starts to jam, the key does not turn well. You can fix it by cleaning debris, lubricating or replacing the locking mechanism. The type of repair depends on the type of damage.

If the canvas is worn, you can replace its lining. To do this, it is enough to remove the old finishing material and attach a new one. Peeling paint, the appearance of rust is also easy to fix on your own. The canvas is removed from the hinges, placed on a flat surface. All paint must be removed, and areas affected by rust thoroughly cleaned. After treatment with a primer, the front side is covered with a protective mixture.

The skewed canvas must be adjusted by tightening the hinges. It is also worth doing if the sash sags, does not close well. You can eliminate the creak by lubricating the loop mechanism.

Interroom

Wooden, plastic door structures that delimit the space inside the apartment are not affected by temperature changes, but may become unusable from other factors. These are physical impact, ultraviolet rays, frequency of use. Problems with interior doors:

• subsidence;
• cracking;
• loosening, breakage of loops.

The sagging of the door leaf is a consequence of the wear of the hinged iron mechanism. To solve the problem, the loops are unscrewed, and new ones are put in their place. For fastening, self-tapping screws are used, which are dipped in epoxy glue before screwing in. To restore the level of the loops, you can put washers on the axis.

Attention! The loosening of the hinges can be removed by tightening the screws. In difficult cases, fasteners may need to be replaced. In other cases, you will need to call the wizard.

Cracking is eliminated by removing the fabric from the hinges, cleaning the protective layer. All affected areas must be treated with sandpaper, then with a special mixture for leveling, apply a protective layer on top.

Kupeynykh

If the operation of sliding models deteriorates, you need to collect dust from the guides with a vacuum cleaner. If the problem persists, the top rail is checked - a wheel often pops out of it. Regular checking of the stoppers will help to avoid breakdowns. If they are open, they must be closed.

Loosening of the mounting plate is a common malfunction. To eliminate it, it is necessary to fix it or replace it if it cannot be fixed. The mounting plate is set as evenly as possible, otherwise there will be deformations.

What can not be done when repairing a door?

So that troubleshooting does not lead to trouble, you should not:

• lift a heavy metal sheet alone, trying to remove it from the hinges;
• use sharp objects to clean the top layer;
• use faulty electrical equipment.

The front door should protect the building from uninvited guests, cold, noise. If the structure breaks down, it turns into a heap of material unable to cope with the functions. Timely detection of a malfunction and its elimination helps to extend the service life.

Metal is a strong thing, but sooner or later everything in this world falls into disrepair. Entrance doors, like no other, are constantly subjected to diverse loads and the probability of failure of one or another node is very high here. Next, we will step by step analyze the repair of iron entrance doors. That is, first we will talk about the most likely breakdowns, and then you will learn how you can fix them yourself.

Scheme of the most common version of the iron door.

Any repair, including the repair of entrance metal doors, begins with a diagnosis. Believe me, this design is not so complicated that you cannot figure it out. Here is a list of the main failures:

• Locks - there are relatively few lock designs, here you need to decide on the type of lock, after which it will become clear whether you can quickly repair it or it's time to call a specialist;
• Accessories - this includes handles, pads for locks, hinges and a peephole;
• Door frame - often metal doors have an all-welded frame. There is nothing special to break there, but there is a problem of distortions and improper fastening;
• Directly the door leaf - as a rule, for the layman, the repair of the entrance metal door is limited only to the leaf. The problems here are mainly 2 - the first is the loss of a respectable appearance, and the second is the destruction of integrity, in other words, hacking;
• Platbands - the outer lining of the door is quite often subject to mechanical breakdowns, it is good that the repair of an iron or wooden lining is quite simple.

Not every door breakdown can be repaired by hand.

By the way, if you decide to repair some node, for example, to replace the lock cylinder, it will not be superfluous to diagnose and prevent all components of the structure. It is easier to prevent a problem at an early stage than to frantically look for ways to solve it later.

What can be repaired in iron doors and how

Repair of entrance iron doors directly depends on the place of their installation, so doors in city apartments break much less often compared to structures that go directly to the street, but the breakdowns of all doors are about the same. Most often, locks break, and we will start with them.

Lock repair

In general, there are 5 types of locks - cylinder, leaf, bolt, electromechanical and combined. But most often there are cylinder and level. Details about all types of castles with photos and videos are described.

Repair of steel doors with a cylinder lock is considered the simplest and least expensive. In such locks, the cylinder into which the key is directly inserted is removable. Replacing it is not difficult even for a complete amateur. The general algorithm of actions is something like this:

• From the end of the door on the lock bar, opposite the larva, you will find a locking screw, it is there alone, so it is impossible to confuse;
• This screw with a regular Phillips screwdriver must be unscrewed and pulled out completely;
• Then you insert the key into the keyhole and start turning it slightly and at the same time try to pull out the larva;

The location of the locking screw in the cylinder lock.

• As soon as the tongue inside the mechanism “hides” into the larva, it will freely exit the lock;
• Now you take a broken larva, go to the store with it and buy a similar one. After that, you just have to insert a new larva into the lock and fix it with a locking screw;
• But before going to the market, it will not be superfluous to deal with the types and intricacies of choosing larvae for cylinder locks, all this information is there.

You are unlikely to be able to repair a lever or bolt lock with your own hands, so here we are only talking about replacing the entire mechanism.

When replacing the lever lock, the handle is removed first.

• If there is a handle on the lock, then it, together with the lining, is removed first. Mounting screws must be sought from the inside;
• Such locks can be cut from the end of the web or installed inside the web. In the first case, you just need to unscrew the fixing screws from the top and bottom, after which the lock should easily pull out;
• If the lock was attached inside the leaf or a crab-type locking mechanism was installed (locking on 4 sides), then in order to get to the lock, you will have to remove the inner patch panel completely. Having gained access to the lock, you unscrew the fixing screws in the same way and change it.

If the lock is inserted from the inside, then you will have to completely remove the inner lining.

In some expensive models of lever locks, it is possible to recode the lock to a different key. Therefore, if the keys are lost, it is not necessary to change the lock, you can simply recode it for a different set of keys.

Skewed door frame

The box can skew for 2 reasons - the first is not a good enough fastening with a heavy door leaf, and the second is shrinkage at home, but it only happens in new buildings. As a rule, the box warps gradually, and if you notice that the doors began to close poorly and rub against the upper or lower edge of the box, then you can correct the situation in one of 3 ways:

1. If there are no obvious deformations of the box itself, and the doors sagged due to gravity, then you need to tighten and adjust the hinges, plus it is advisable to install an additional canopy in order to reduce the load on the existing ones. Ways to adjust the canopies are shown in detail, and you can find out about the choice of hidden loops;
2. Old doors can sag due to the wear of the hinges, there is no need to embed anything else here, just adjust or change the existing canopies;
3. You can correct the deformation of the box by driving in a few wedges, but when the box is in place, you will need to additionally fix it by driving 2 - 3 anchors, next to the old fasteners. The technology for attaching the box to different types of walls is shown in detail.

A deformed box can be corrected with wedges.

Loss of appearance

If the door leaf is worn out and the appearance leaves much to be desired, then the repair of metal doors will depend on what the leaf is lined with.

The lowest budget option is painting. During operation, the paint on the metal is scratched and islands of rust appear, the lower sector suffers most from this. In this case, before painting, it is desirable to completely remove the old paint from the canvas.

If there is no desire to clean the entire canvas, then you need to sand at least the affected areas to white metal. There are many ways to strip, but the easiest way is to buy a nozzle with a metal cord brush for a drill or grinder. You can clean the entire door with it in an hour and a half, and it will take 15 to 20 minutes for a fragmentary repair.

The easiest and fastest way to clean metal is with a cord brush.

The cleaned canvas should be degreased with some solvent or acetone, after which at least 2 coats of paint are applied. Paint should be taken for outdoor work, for the repair of iron doors it is better to take the so-called hammer paints.

For those to whom conventional painting is not suitable, there are a number of alternative options for facing the front doors:

• Leather - genuine leather for upholstery of doors is used extremely rarely. Budget options are lined with leatherette, and eco-leather is used for the elite sector. In appearance, eco-leather practically does not differ from natural, but it costs several times cheaper. The “carriage coupler” looks best, step-by-step instructions for upholstery of doors with leather are shown;

The carriage screed on the front doors looks luxurious.

• Laminate - metal doors can be sheathed with ordinary floor laminate, but when buying, you need to pay attention not to the level of abrasion, but to moisture resistance. The disadvantage of this method is that it is not advisable to veneer canvases facing the street with a laminate. There is a step-by-step instruction for facing the door leaf with a laminate;
• MDF - laminated MDF panels now cost about 50% of iron doors, professionals call them MDF cards. Such a lining looks luxurious, it changes quite simply, the only negative is the high price. There are MDF cards for the street and for indoors, if you mix them up, then in a year you will repair the doors again;

MDF cards are now placed on more than half of the entrance metal doors.

• Natural wood is a good option, but expensive. Plus, such wood must be carefully impregnated and varnished with high quality, otherwise it will not last long.

There are detailed instructions for lining the door leaf with different materials with your own hands.

The wooden cladding of the entrance doors speaks of the status of the owners.

Platbands on entrance metal doors are rarely installed, because their role is played by the outer part of the door frame. But if the platbands are still standing, then if they are damaged, this element changes completely, and the replacement technology is shown.

Also, do not forget about such an important point in the operation of doors as lubrication of canopies. If you do not lubricate the creaking doors in time, they will break very soon and then you will have to seriously repair. The technology and choice of grease for door hinges is shown.

Conclusion

We do not claim that absolutely any damage to doors can be repaired by hand, for example, if a Chinese door was opened like a tin can, then a complete replacement is needed here. The same options that are described above have been repeatedly tested in practice and work exactly, so you can safely use them.

If you do preventive maintenance in time, then repairs to iron doors will not be needed for a very long time.

Capital metal doors are a strong thing, but over time they break. It is believed that the repair of entrance iron doors is available only to professionals, in fact, an amateur can fix most of the nodes 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

What can be repaired in iron doors on your own

In a standard iron door, 80% of breakdowns can be repaired with your own hands. True, a lot here depends on the availability 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 assistants and expensive tools are not needed 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 the canopies, the hinges on the metal doors are under heavy load, so they need constant attention. Most often, the repair of canopies of iron doors ends with their adjustment.
• Sometimes related fittings fail, this includes door handles and a peephole. Often, the repair of these nodes does not make sense, so they are immediately changed, although there are exceptions.
• All metal doors have an all-welded box. A closed iron circuit is difficult to break, but there are 2 weak points here too. Firstly, errors can be made during installation. Secondly, the box can warp when the house shrinks, but shrinkage processes are usually inherent in new houses.
• The external repair of the entrance metal door is related, in other words, you can live with a scratched lining, it does not affect the functionality, but we will also tell you how to restore the iron door.

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

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

Repair of locks on iron doors

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

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

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

Cylinder locks with English head

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

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

Instruction:

• 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 there alone, so it is difficult to confuse

• now you need to try to remove the cylinder head;
• if you can’t immediately remove the head, then you need to turn the key again to try to remove the mechanism, inside there is a cam that should be in the zero position, then the head will come out;
• then you 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, to get to the mechanism, you will have to partially or completely dismantle the inner lining of the doors.

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

With end mounting, the outer bar 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 opened, it is useless to unscrew them, since there are additional clamps inside

Lever locks are quite reliable, and if the mechanism starts to act up, 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 inspect 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 the breakdown is elementary debris. The lock just needs to be blown, cleaned and lubricated.

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

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

Iron door hardware repair

The peephole on the front door breaks extremely rarely, unless vandals ruin it. Replacing such fittings is simple, the 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 socket is a separate mechanism not connected with the keyhole.
• 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 socket and on the bar are approximately equivalent.

To replace the handle on the socket, 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.

Handles on the socket are mounted in metal doors using two through studs

The door handle on the bar 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.

Replacing 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 tear off the old gasket, then clean and degrease the metal. New moldings usually have a base with a self-adhesive coating. The master only needs to pull off the protective strip and glue the seal to the doors or door frame.

Replacing seals does not require special skills and high qualifications

Repair of steel door canopies

2 types of awnings are installed on home metal doors - simple, "dad-mother" type and hidden. Both options can be adjusted, but the instructions are different.

Adjustment of simple awnings

Now in the domestic sector, more than half of the iron doors are installed on simple and reliable hinges of the "father-mother" type, they are practically not amenable to adjustment, but they break extremely rarely.

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

These canopies have 2 problems, either the lubricant has dried up, or the canvas has sagged under its own weight. In the first case, you just need to pump lubricant there. If the canvas sank precisely due to the fault of the awnings, 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 drawdown. In iron doors, the gap between the leaf and the box around the perimeter is 3-5 mm. When the canvas sags, it begins to cling to the threshold. Here you need to measure how much (relative to the threshold) the canvas sank and add another 3 mm to this value.

There are two ways to eliminate subsidence.

• If the door has sagged a lot, then you need to remove it from the canopies and insert a steel ball from the bearing inside the canopy.
• 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 on any construction market, for the 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

Adjustment of hidden awnings

Another "headache" is the adjustment of hidden canopies 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 screws for the hexagon around the perimeter.
• Then loosen the locknut on the eccentric (the eccentric is always in the center).
• Now, by rotating the eccentric to the right or left, you 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 around the perimeter of the canopy, but the adjusting eccentric is always in the center

But there is 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 and painted in detail with photos and videos.

Iron door frame repair

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 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 find this out using a bubble level.

The skew of the box can be easily identified using 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). Next, drive the 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. At the same time, the old anchors can not be removed, the design 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 during shrinkage of the house is carried out in a more radical way. In this case, the strong metal studs are bent as a result of 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 clamp it with a canvas, trying to remove it. Where the sheet is taken out freely and 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 has gone towards the wall, then the box is leveled with 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, so the redecoration of iron doors is more important for many owners than, for example, adjusting awnings. There are several options for self-restoration.

• carriage screed. This method of facing has been around for about 200 years. In addition to a solid appearance, soft 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 are step-by-step instructions for choosing a material and arranging a carriage tie.

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

• Laminate finish. Floor laminate is considered an excellent option for self-cladding iron doors. The coating is anti-vandal and quite hardy. The only place where laminate flooring cannot be installed is the street. Instructions for lining doors with laminate flooring are located.

If you have a tool, finishing the entrance doors with a laminate is quite accessible to an 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 fasten 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 shields. The technique for arranging the last three options (painting, MDF cards and natural wood) is described and shown in detail.

Conclusion

Of course, it is far from always possible to repair metal entrance doors with your own hands. I talked about those methods that are guaranteed to work. The video in this article shows the most interesting points clearly. If you have something to add or have any questions, write in the comments, I will help you as much as I can.
