How to install an entrance door in an apartment. How to install entrance doors? Tools required for work

There is a huge number of proposals for entrance doors on the market - here not only metal constructions but also wooden. And as practice shows, reliability is determined not only by the quality of the product itself and the materials from which it is made, but also by competently carried out installation. Installation entrance doors- it is a responsible business, therefore, so that the end result does not disappoint, it is recommended to study the installation instructions.

Measurements and preparation of the opening

So, the old front door no longer corresponds to its purpose, both in terms of functionality and reliability. It is necessary to purchase and bring to the house (apartment) a new model, which is selected both in appearance and in functional indicators, and in size.

But before going to the store, you need to take the dimensions of the doorway. You need to get to its ends, which are hidden under the platbands with a layer of leveling mortar and polyurethane foam:

1. The platbands are dismantled, there is no need to stand on ceremony with them, in the future they will no longer be useful.
2. The plaster layer is removed.
3. If polyurethane foam was used during installation, then it will have to be removed.
4. The threshold is dismantled.

The front door is in front of you, and the edges of the loot (as the door frame is called in professional language) and the ends of the opening are clearly visible. There is always a gap between them. Now you need to measure the distance between the opposite ends of the opening. This should be done in at least three places with equal distance between measurements. It is the same with the horizontal direction. Of these, the smallest values ​​are selected, which are taken as the basis for the dimensions of the door frame with a deviation of 1-2 cm to the smaller side.

For example, if the height of the opening turned out to be 2.12 m, then the size of 2.1 m is taken to select the height of the trap.

The principle of correct taking measurements from the doorway

It should be noted that different manufacturers has its own model line, in which each door has its own dimensional parameters. Therefore, the actual dimensions of the opening will have to be adjusted to the standard door structures from a particular model range.

The complexity of dismantling the door frame will depend on what material the walls of the house are built from. If it is gas, foam or expanded clay concrete, then all dismantling work must be carried out with great care - it is important not to spoil the fragile masonry, which is prone to chips.

In general, the procedure is as follows:

1. the door leaf is removed from the hinges;
2. the box is cut with a grinder or a hacksaw into several parts.
3. cut pieces are dismantled with a crowbar or crowbar.

Cleaning the doorway

Cleaning consists in removing old fasteners, flimsy plaster mix and, if any, polyurethane foam from the ends and adjacent areas.

But if the house is old and the front door has been in operation for more than a dozen years, then it is necessary to check the floor beam, which is installed above the doorway. If its quality leaves much to be desired, then it is worth considering how to replace it. It is better not to carry out this repair operation with your own hands.

Pay attention to the area below the threshold. Usually, in brick houses that have been in operation for a long time, wide openings are formed, filled with brick loose material, so this debris must be disposed of.

Sealing cracks and voids

When all defects in the doorway are found, they must be repaired with ordinary cement-sand mortar, which is diluted in a ratio of 1: 3 (1 part of cement to 3 parts of sand). Large voids are filled with broken or solid bricks and mortar. Small ones - only with a cement mixture, the same applies to cracks. It is recommended to use a deep penetration primer before sealing the latter. It will not only hold together the grains of the wall material, but also go deeper into the thickness of the concrete, making it more durable.

There is no need to align the surfaces of the ends of the doorway. You can raise the floor, fill the screed, or level the place under the sill.

Installation instructions for entrance doors

Several useful tips before starting installation work:

Box installation

First of all, the door must be disassembled into two parts: the canvas and the frame. The latter is installed in the doorway and set at the level both vertically and horizontally. In this case, the installation is done on stands made of wood or plastic. It is best if these are tapered inserts, which will be easy to knock out after the end of the installation work. Although sometimes the craftsmen do not touch them, leaving them in the opening as additional support.

Please note that the entrance door is flush with the outside of the wall. And it should open outward. After setting, the diagonals of the frame are checked, they must be the same in length.

Methods of fastening the structure

There are several ways, so each must be considered separately. It is necessary to fasten the door frame at least at 10 points: 2 at the bottom and at the top and 3 at each vertical end.

Through the eyelets

Manufacturers of metal door models offer designs that already include so-called eyelets - metal strips welded to the frame, in which holes for fasteners are made. Therefore, the fastening process itself is as follows:

1. the strips are bent to the wall surface so that they are pressed as tightly as possible;
2. holes are made through the holes with a perforator to fit the size of the anchor length;
3. the latter is inserted through the eyelet into the hole in the wall and tightened with a wrench.

Steel reinforcement pins can be used instead of anchors. They are driven into the hole, and the ends are electrically welded to the lugs. To increase the strength of the fastening, cement mortar can be poured into the hole, and then the pins can be hammered. If it is reinforcing rods that are used as fasteners, then the depth of the hole should be within 15 cm.

Through hole

Some manufacturers of entrance metal doors at the stage of their production provide through holes in the ends of the frame. If there are none, then you can drill them with your own hands using a drill or puncher.

Through the holes, a punch makes recesses in the ends of the opening, where either anchors or pins are inserted. If the front door is made of wood, then only anchors are used for fastening in this way, the nuts of which must be recessed into the body of the frame. Therefore, under them, an expansion of the hole is made to the size of the diameter of the nut, and the seating depth should be equal to the thickness of the fastener. The pins are not used in this case, because there is nothing to weld them to.

Through metal grips

This option for attaching the entrance door is possible only if, in addition, a metal edging from a profile steel corner is installed from the outer edge of the opening.

It is necessary to weld metal strips 3-4 cm wide, equal to the width of the opening end, and 2-3 mm thick at the points of attachment to the door strip on the inside. They are welded either perpendicular to the parts of the box, or obliquely. There are no particularly strict requirements in GOST.

Thus, from the outside, the box is held by an edging, and from the inside by metal hooks.

And a few more useful tips about the sequence and correctness of the attachment:

• you need to start fixing the box from the side of the hinge installation;
• the process itself is performed from top to bottom;
• after each fastener, the box is checked for the verticality of the installation: they fixed one side, hung the canvas, checked whether it opens well - you can go to the other side of the loot; the same with the top and bottom.

End of the installation process

The check showed that the door is correctly positioned, it opens and closes freely. The door leaf must be removed again, and the surfaces of the loot must be pasted over with masking tape, because it is time to close up the gaps and carry out the finishing.

1. Polyurethane foam fills the gap between the ends of the opening and the box. It will not only serve as a filler, but also as a heater. By the way, you may find useful information on how.
2. The same can be done with a cement-sand mortar, to which stucco is added. The latter sets quickly, so the solution dries quickly.
3. The surface of the gap is putty to maximum evenness. To do this, you may need to apply the mixture in several layers.
4. They make slopes that are painted or covered with decorative material.
5. Install extensions, if necessary.
6. Masking tape is removed.
7. From the outside. If the door is wooden, then they are attached to the frame with self-tapping screws, the caps of which are recessed in the wood by 0.5 mm. After that, the caps themselves are closed with decorative caps. If the box is metal, then the platbands are attached to it with rivets, screws or bolts.
8. Handles are installed on the door, hinges are lubricated.
9. The door leaf is hung.

This is a step-by-step technology for installing a door in a brick or panel house.

Installation in openings made of gas, foam and expanded clay concrete

Expanded clay block private house or buildings made of gas or foam blocks belong to the category of buildings with fragile load-bearing structures. Therefore, in order to install an entrance door in them, it is necessary to take into account two important requirements prescribed in SNiP and GOST:

1. Increase the number of fasteners on the vertical sides of the box within 4-6 on each side. At the same time, the depth of their placement should not be less than 20 cm. To fasten metal doors in a foam concrete wall, you cannot use standard metal anchors, which in soft blocks quickly loosen due to intensive opening and closing of the door. In such houses, according to the standard, it is better to use chemical anchors, for example, Hilti.
2. Install a crimping structure of two frames made of steel corners with a shelf width of 40 or 50 mm. In fact, it is all the same edging, only on both sides of the wall. Both structures are fastened to each other with crossbars made of metal plates 3-4 mm thick.

Installation in a wooden house

The installation of the door structure is carried out according to the following scheme:

1. A siege is made along the opening - this is a powerful wooden box made of beams.
2. A door frame is inserted into it.
3. The box is fastened to the casing with long self-tapping screws or screws. It is important here that the fasteners do not go through the casing.

More details on this process can be found in the article.

Accuracy of taking measurements, a strictly step-by-step procedure for carrying out operations, correct placement of the loot in all planes and reliable fastening of the door are the basic rules for its installation and a guarantee of the quality of the final result.

Installation steel doors will help to protect housing from the penetration of unauthorized persons, and also perfectly protect the room from drafts. Possessing minimal construction skills and the necessary set of tools, you can independently carry out the installation of doors without hiring professionals. Correctly made installation of metal entrance doors will contribute to the long service life of the product.

Before you start installing a new reliable iron door, you should dismantle the old one. First, it is removed from the hinges, and then the door frame is carefully removed. To do this, using a nail puller, pull out all the nails and pull out the frame, applying a little effort if necessary.

If the nails are firmly entrenched in the door frame, then it should be sawed in several places so that you can pry it off with a crowbar or nail puller.

After removing the door frame, the doorway is thoroughly cleaned of plaster residues and protruding nails.

It should be remembered that, ideally, the opening should be slightly wider than the door block (by 15-25 millimeters). Therefore, you need to correctly measure the height and width.

What to do if the opening does not match the ideal parameters:

• The narrow opening should be widened using a hammer drill or grinder with a circle marked "stone / concrete";
• A very wide opening is laid with bricks in one row;
• A slightly narrowed opening should be corrected with a mortar made on a cement-sand base with the addition of plasticizers.

At the end, the opening is carefully cleaned and trimmed. The easiest way to prepare the opening is in a brick house.

How to install an entrance metal door to an apartment with your own hands

If there are special iron plates with holes on the sides of the door frame, then there will be no difficulties with installing the doors. But this method of installation is possible if the door is adjacent to the wall on both sides, for example, in a narrow corridor.

Installation technology:

1. The door block should be installed in the opening and leveled using tools: level and plumb line. The result obtained must be secured with wedges and re-checked for correct installation.
2. Holes for fasteners are drilled in the wall, at least ten centimeters deep.
3. We drive in metal rods, riveting their upper part.
4. Then you should check if the door has been skewed during installation. To do this, open and close it several times. It is necessary to make sure that the locks and latches work well without jamming.
5. The opening is sprayed with water and filled with polyurethane foam.
6. When the foam has completely solidified, you need to trim it. Usually this is done the next day, and until that moment it is strongly discouraged to use the door in order to avoid distortions.

According to fire safety requirements, the door must be torn off from the outside so that apartment residents can freely leave the room during a fire or smoke.

How are anchor bolts used to secure metal doors?

Anchor bolts are one of the most common fasteners used when installing a door frame. They are made from durable grades of steel and coated with a special anti-corrosion coating. These fasteners are able to withstand heavy loads for a long time, even in seismically unstable areas. Therefore, their use when installing doors is quite justified. What kind of fasteners are needed, they will tell you in the hardware store.

Installation using anchor bolts:

• The door is leveled in the opening and secured with wooden struts;
• Opposite the special holes in the door frame, cavities are drilled for the anchors;
• The anchor must be inserted into the holes and hammered, and on top put on the plugs painted to match the doors;
• The opening is blown out with construction foam.

If there are no holes for the anchor, then they should be drilled in the side posts (three pieces on each side). Fittings are driven into them and welded welding machine to the doors.

Correct installation of an entrance door in a private house made of wood

In the first year after construction wooden house doors are usually not installed, since the material shrinks, and all openings become lower, sometimes even 15 millimeters. In such conditions, any door can deform and stop working properly. After the shrinkage of the log house, you can safely install doors and windows.

Tools required for work:

• Level and plumb lines;
• Hand or electric drill;
• Chisel and hammer;
• Roulette;
• Hacksaw with a cloth for wood;
• Plane (conventional or electric).

First, the size of the log house is adjusted to the door frame. It is desirable that it becomes end-to-end, but a gap of no more than one centimeter is allowed. The excess wood is chopped off by a plane, and its deficiency is compensated for by stuffing wooden slats. If there was no opening initially, then it is easy to cut it with a saw, having previously calculated the dimensions.

When installing the box, the door should be removed from it to make it easier to level it. Long wood screws are screwed into special holes, which will securely fix the door frame. On top of them, special plugs are installed.

Then the door is hung back and adjusted. It should not sag and warp.

The wide gaps between the box and the frame are filled with foam, and the narrow ones are covered with insulation (tow).

Beautiful platbands are stuffed on the outside and inside.

A few tips: how to strengthen a metal entrance door

Additional reinforcement of the doors is necessary to protect them from burglary. No matter how impressive the door looks, there are always professionals who can easily break it open or knock it out along with the jamb.

Methods for strengthening entrance doors:

• It will be advisable to install additional hinges or replace the existing ones with reinforced ones, which are sold in specialized stores.
• The locks must be installed at a considerable distance from each other, for example, one at the top of the door, and the other in the middle.
• The more the door frame fasteners are recessed into the wall, the less chance it will be knocked out.
• The installation of special anti-removals will prevent it from being squeezed out with a crowbar.
• Iron squares can be fixed along the perimeter of the doors and their edges can be driven into the wall.
• If you put a safe door, then it will be almost impossible to break it.

Sometimes door installers offer door reinforcement and burglary protection services. In this case, you should heed the advice of professionals.

Correct installation of metal entrance doors (video)

Entrance doors, both in a private house and in an apartment, are easy to install yourself, first having carefully studied all the recommendations of the masters and correctly making the necessary measurements. Then they will not warp or sag even with an intense load, and it will be possible to save on the services of installers. large sum of money. Observing all the rules of installation and operation, you can ensure that the doors will last at least 20-30 years without requiring adjustment and replacement.

Installation of entrance metal doors is a laborious process that requires certain skills. However, in order to save money, some people decide to do it on their own. This article will take a closer look at this procedure.

First of all, we will prepare a tool for installing metal doors. So, you need the following:

• Perforator (preferably as powerful as possible). In its absence, you can use an impact drill with the appropriate attachments.
• Measuring instruments - tape measure, plumb line, level (ideally laser).
• Grinder with a large circle.
• Board, saw - this is needed to create pegs.
• Joint filling material - polyurethane foam or cement mortar. The first option is simpler, and the second is more durable.
• Fasteners (anchors, rods, etc.). It is better to purchase them complete with a door.
• Hammer and chisel.
• Wrench for tightening the fasteners of the appropriate size. Or a screwdriver with the correct bit.

If you do not have a hammer drill or grinder, and you do not plan to buy such an expensive tool, you can rent it. In many cities of the country there are organizations that provide such a service.

A few words about measurements

The first step is to measure the width and height of the opening. You need to measure not from the box, but from the concrete (or brick) base. Only then can you go to the store. There are two options:

• Order a door for the size of the opening.
• Buy a ready-made model with similar parameters.

In the first case, the purchase will cost much more, but you will not have to spend energy on expanding (narrowing) the opening. If the current canvas is a new sample, then it will be possible to choose a model that is ideally suited to the size. In "Khrushchevs" and other typical houses built in the USSR, as a rule, openings of non-standard sizes. Therefore, the installation technology assumes expansion. This operation will require a lot of physical strength.

Before placing an order, decide in which direction the closing will be done. If your apartment is against the wall and there is a distribution box (with automatic machines and meters) hanging on it, then it is best that the handle is on the other side. In this case, the canvas will not knock on the box.

We make the expansion and preparation of the opening

Correct installation of a metal door begins with adjusting the opening. If it fits in size, then you just need to level the original surface. For this we use a thick cement mortar. It is recommended to align in several layers. Throw in the mixture by hand or with a spatula, and then level it with a spatula.

Increasing the opening is a very loud and messy step. Therefore, inform your neighbors about this so that you can choose a time when they will not be at home. First, we apply a marking (U-shaped) around the perimeter. So there are two options. The first is to take a powerful grinder with a large (at least 40 cm in diameter) disc on concrete and simply remove a layer of concrete of the required thickness. In this case, there will be a lot of construction waste.

The second, more gentle option:

• We take a punch with a drill larger than the thickness of the wall.
• We drill through holes in the wall along the entire perimeter with a minimum step.
• Using a hammer and chisel, gouge out the excess concrete.

Important! It is necessary to leave a technological gap of a few centimeters so that the position can be corrected. The slots will subsequently be repaired.

This technique will take more time, but you will bring less discomfort to your neighbors. At the end, we level the surface.

The main scope of work

How much it costs to install an entrance metal door worries many. This service will cost at least 4 thousand rubles (depending on the size and complexity). Therefore, doing the work yourself is a rational option, especially when it comes to an inexpensive model, because installation in this case can cost more than the purchase itself.

Advice: if the weight of the complete structure is small, and you have enough strength to work with it, then you do not need to take the canvas out of the box.

So, you need to do the following:

• The first step is to check the operation of the canvas. We insert the structure into the opening.
• We check with the help of a level and a plumb line the verticality and conformity of the dimensions. It is necessary to achieve perfect accuracy - a misalignment of even a few millimeters will disrupt operation. If any surface irregularities are found, they must be eliminated.
• Having achieved a perfect fit, the box must be secured. To do this, insert wooden pegs into the existing gaps (at least 4 pieces for each side).
• Having done this, we once again check the evenness of the position.
• Now we fix it with fasteners. In budget models, anchors may not be included, they will need to be purchased separately. It is advisable to consult with a sales assistant when purchasing.
• The main rule is that there should be at least three fixation points on each side. Only then will correct installation be guaranteed.
• First, we fix the side on which the hinges are located. There are mounting holes on the box - through them we drill for the installation of anchors. If they are absent on the jamb, they will have to be first made with a drill with a drill for metal. We do 3 for each side with approximately equal steps.
• After drilling the holes, insert the bolts and tighten the nuts securely. We carry out this procedure for all parties.
• We insert the canvas (if we removed it). We check the smoothness of the movement: the door should not open spontaneously. We install it in different positions. She should not walk in any of them. If such moments are observed, it is necessary to adjust the fasteners.
• To adjust the position, loosen (tighten) the nuts. Pay due attention to this aspect - it will be impossible to make adjustments in the future.

Final stages of work

This completes the installation of an entrance metal door with your own hands. Now you need to close up the joint that appears. Polyurethane foam is simple, but not the most reliable option... In addition, its use greatly facilitates the work of crackers. Therefore, we strongly recommend using a cement mortar to which plaster should be added.

The work is simple:

• We close the joint from the side of the apartment with any even material at hand (plastic panel, board, etc.). This will prevent the mixture from falling out into the hallway.
• Armed with rubber gloves, we throw the solution into the gap from the side of the entrance. You must fill it in completely.
• Using a spatula or trowel, level the mortar.
• We go into the apartment and remove the set obstacle.
• Putty on this side.

The cement mixture dries out for a day (sometimes two). Therefore, at this time, try to reduce the operation of the door as much as possible in order to prevent cracking of the solution. Do not forget to check the operation of the locks and handles - they should work smoothly. In case of the slightest defects, ask for replacement. We recommend immediately lubricating all moving parts (keyholes, hinges, etc.). The WD -40 is perfect for this.

Installing metal doors will make those who decide to do it for the first time sweat. But without this stage, repairs or completion of construction are impossible, so we decided to help and gathered the experience of professionals in this article.

A little about the front doors

Probably the most conservative detail of the interior of any apartment is the front door, the installation of which more and more men are trying to do with their own hands. Both metal models and wooden ones are equally popular. Having passed the evolutionary path from the skin that blocks the entrance to the cave to the modern armored miracle with tricky locks, it essentially remained what it was intended for - a kind of border defining the boundaries of ownership. Installation of an entrance door today, in addition to creating a barrier at the entrance to the premises, has a goal of cold.

As a rule, they are hinged. This type is also subdivided into "right" and "left", depending on where the loops are located. The main drawback in installing a swing-type entrance door is the need for opening space. Because of this, it is imperative that appropriate changes be made to the layout of any room where such a view is provided. The point is not only in the radius of its opening (it must be indicated on the plans), it is also necessary to take into account the fact that in addition it will be necessary to leave room for the passage of a person, and after all, he may have a rather voluminous object in his hands.

Basic materials for entrance doors

More often than others, when installing entrance metal doors, there are those that are made according to the standard defined by the model with the SL-2000 index. It is based on two sheets of alloy steel 1.5 mm thick and welded together at 200 points with horseshoe-shaped ribs. The lock should be cylindrical in shape and have up to 9 steel bolts (hardened alloy), which, when locked, enter the walls and floor from all four sides of the door leaf. If you assemble it before installing a metal door, then the thickness will be at least 50 mm.

Opening and closing of such a product is easy and quiet. The design is simple, does not distinguish it from other doors, does not attract attention. If you have to install the front door with your own hands, then it is curious to know that the total weight (without the box) is 50 kg. Required condition for safety - the purchase of an additional end valve and a telescopic peephole with a large viewing angle. It is also believed that if you install a metal door according to all the rules and using special materials, then it will have perfect sound insulation.

The dimensions of the product are not strictly fixed, they can be made different in accordance with the client's requirements. Both natural and artificial materials are used in external and internal finishes. The apartment looks very solid after the installation of entrance metal doors with wood trim. As an additional safety measure, it is possible to equip with a special part ("insert"), which increases the height and weight of the structure.

On a step below the installation of metal doors, there are models in the construction of which aluminum and PVC profiles are used. Do not disdain such constructions. Yes, they are a little weaker than steel ones, but the cost for the canvas itself and its installation is much lower. As a rule, Chinese enterprises are engaged in the supply of such products. Doors are assembled in an industrial way, and this ensures that their quality is at the proper level. Also, do not forget that there are laws. This means that if an official store took a Chinese door for implementation, the quality requirements adopted in our country are fully met.

Oddly enough, but the industry does not forget about the production of wooden entrance doors. They did not become very popular, but with the development of demand for products with an increased level of safety, the requirements for them also changed. Strengthening the structure, supplying wooden door hermetic seals and gaskets, the presence of a threshold.

Removing the old box

Do-it-yourself installation of entrance doors gives many opportunities to make a mistake, which will then cause a distortion, or even a breakdown of the product. But you don't always want to use the help of specialists, because more and more negative reviews are found against installers, even reputable companies. If personal experience in such an area is not at all, then it is better not to tackle the installation of iron (steel) doors with your own hands. If you had to work with at least wooden model then you can try.

First you need to dismantle the front door, this can be done by hand and when calling professional installers, and it is metal or some other almost irrelevant. The first step is to separate the canvas from the box. It is better, of course, to do this together with someone, because its weight can be too heavy, and removing from the hinges can be very traumatic.

Then remove the anchors and nails from the door frame holding it in the opening. Make cuts in the sidewalls in several places. It will be much easier to remove these elements piece by piece. Then the upper and lower parts can be removed from the opening. Difficulties can arise if you had a metal box. You can't do without a grinder. Having freed the doorway from the old structure, it is also necessary to clean it of sound and heat insulating materials and tap the edges of the perimeter with a hammer so that the remnants of mortar and plaster do not interfere with subsequent installation. Now let's move on to installing metal entrance doors.

Mastering installation using the most difficult example

Since it is simply necessary to install the front door correctly, otherwise you will have to pick it out back according to the above method, that is, by destroying the structure, then we will consider how to do this.

How to install a metal front door with your own hands - a step by step diagram

Step 1: adjust the doorway

Installation can be complicated by the fact that the size of the perimeter does not coincide with the new door frame. This is not necessarily a consequence of the Chinese origin of the goods, often such a problem awaits you in Stalinist houses. If the new door frame is wider or higher than the opening, you will have to cut out additional space from the walls or make a recess in the place where the threshold was.

Do not forget about the technological gaps between the wall and the door frame in order to be able to make adjustments during installation.

It happens that the door structure is less than the opening in width or height. This can happen when buying an imported product for standard buildings already mentioned in an unkind word. Depending on the difference in dimensions (clearance), adjustments must be made. If it is small, literally a few millimeters, you just need to use door expanders. In the case of a significant distance, it will be necessary to make masonry from silicate brick or wall stone. Do not be lazy to make a bundle with the main wall, so as not to lose strength.

Step 2: Unpacking

Now let's move on to how to install an iron door model with our own hands. We remove the outer packaging and stop. If the door is covered with plastic wrap, do not rush to tear it off, because some inaccuracy is possible during installation, so there will be no unnecessary protection. Anchor bolts must be included in the mounting kit for any door frame. If suddenly there were none, then you can buy them. They should be 10 to 15 cm long and 12-15 mm in diameter.

Step 3: mounting the box

Install the box with an assistant, check it for verticality and horizontalness using levels or plumb lines. Place the wooden wedges and start drilling the anchor bolt holes in the wall. During work, try not to budge the door frame. It is recommended to start drilling from the side where the hinges will be. Then insert the bolts and fix the frame, periodically checking vertically and horizontally.

insulation works. At the end of the installation, remove the polyethylene, if it covered the door leaf, and proceed with the installation of decorative parts. For two days, it is advisable not to use the door or do it gently and as rarely as possible.

When buying new doors, a person has a choice: to entrust the installation to specialists (and pay a certain amount for this) or to install the entrance metal doors on their own (having received a bonus for their work in the form of that same amount in their pocket).

Can you handle it? Of course, there is nothing super complicated about it. You just need to have the necessary tools and clear instructions available. And of course, no one cancels a common mind and a pair of hands that are not afraid to work hard.

Preparatory work

Let's take a simple example of installing a metal entrance door.

Often there is a situation where the available doorway differs in size from the purchased standard door. At the same time, making an opening is always much easier than expanding it. Therefore, it makes sense to select doors with this in mind.

What is the standard door width? Door leaves differ in width with a step of 100 mm in the range from 600 to 1000 mm. In this case, canvases with a size of 600 - 800 mm are used for interior doors and the entrance doors are 900 or 1000 mm wide. This is due to the fact that any standard-sized furniture, as well as household appliances, should easily pass through them.

So, our opening needs to be adjusted as accurately as possible to the size of the doors with the door frame attached to them.

You can reduce the opening using white sand-lime brick or cinder block. You can use aerated concrete. And in order to increase, you will need either a hammer drill or a grinder with a diamond disc. Of course, there is also a technique specialized for these purposes, but it is used only by experienced craftsmen.

With a door width of 900 mm, the opening for it should be 2080 mm in height and 980 in width. This is enough to place the box and provide a technological gap that allows the door to be aligned during installation. Later, it will be filled with polyurethane foam.

Installation of an entrance metal door

It is more convenient to install doors with an assistant. Because the door itself has heavy weight... And it will be much easier to install it when someone can support something if necessary.

So, using the level, the correct position of the doors is determined. While the assistant holds them in position, the master marks the place where the anchor screws are to be attached. The strength and reliability of the door will depend on the quality of their installation. Experienced specialists lower the markings and immediately start drilling the holes into which the anchors are inserted. With this approach to business, the help of an assistant is practically not needed.

You need to start the process from the side of the loops. They are clamped tightly with a socket wrench. Then you can repeat the process on the opposite side of the loot. This operation must be taken with full responsibility, because it is the most difficult and basic part of the installation.

Shimo and thermal insulation of the front door

After the door is hinged, it is necessary to ensure the isolation of the room from drafts and unwanted noise. For this, the space between the box and the opening is filled with polyurethane foam. There are cylinders on sale that are equipped with a special tube. However, the material consumption in this package is very high. A simple foam gun will significantly reduce the over-consumption of polyurethane foam. Specialized packaging is produced for it.

It is advisable to carry out the work behind closed doors. Because the foam when expanding creates some pressure that can deform the new doorframe. Even if it's made of metal.

There are often recommendations to heat up foam cylinders in hot water. However, it must be remembered that as the temperature rises, the foam in the cylinder expands. And when the temperature indicated on the package is exceeded, it can create enough pressure so that everything around is covered with foam after a small but loud "eruption of Vesuvius". If you do not want to have about 50 liters or more of foaming sealant flying on all four sides in the hallway, then follow the instructions for use indicated by the manufacturer.

It is enough to shake the can well at room temperature before use.

You need to blow out all the cracks that are on the side and on top of the door. At the bottom, the foam runs the risk of being destroyed by the load on the threshold with constant walking. Therefore, the gaps between the floor and the threshold are covered with cement mortar.

The foam needs about 6 hours to dry completely. Therefore, it is advisable to leave the doors in the closed position for this time and not use it. The family can go on a visit during this time, arrange a trip to the cinema or a walk in the park.

Adjustment of entrance doors

After 6 hours have elapsed, the doors can be opened and adjusted. If your door is installed by invited technicians, then, as a rule, they do not perform post-installation adjustments. You will need to issue a separate call. Even when the door looks good at first glance, adjustment still does not hurt. This trifle will significantly extend the service life of new entrance doors.

Even subtle distortions of the door leaf in relation to the frame can adversely affect the condition of the awnings and locking mechanisms. Therefore, if there is a desire to extend their service life, you need to ensure that the gap around the entire perimeter of the door is the same. As a rule, manufacturers attach hinges to the doors that have an adjustment function.

Each of the three hinges that hold the door in place has three triangular screws. They have holes for a hex key. On the middle canopy, you need to loosen all the screws, and on the top and bottom two, which are located one under the other.

You will see where the larger gap is. With the upper gap, the third screw of the upper hinge must be loosened, and with the lower gap, respectively, at the bottom.

In this case, you need to adjust the gap, which is located on the side of the hinges. When it is properly adjusted, the others will fit properly.

When the gap is set to the desired value, the loosened screw is clamped, after which the remaining screws on the upper and lower hinge are tightened. The middle loop is fixed last.

That, perhaps, is all. Now your doors will serve you faithfully for a long time.
