Bought from DocDor front door Argus with a mirror. For me, this option turned out to be the best in terms of price / quality. This door as an entrance door is just great, and such a nice addition as a mirror is super, very convenient! I was worried that the mirror might somehow break, but no! With constant opening, closing, clapping, etc. the mirror didn't even move. In addition, the door does not let noise and smells through. I absolutely recommend this door! If something happens to her, then I will buy either her own or an analogue! Thanks to the DokDor company for selling such wonderful doors, fast delivery and high-quality installation!

Six months ago, they set themselves "Italy" from Intekron. Pleasure, frankly, it turned out not cheap, but worth it. Excellent service, excellent workmanship, excellent quality doors.

Previously, I did not think about what qualities the front door should have, in addition to protecting it from thieves. Now he clearly felt all its virtues. Sounds from the entrance are not audible at all. In our apartment, the hallway borders the kitchen. And if earlier in winter there was always a sharp contrast in temperatures, now heat is perfectly preserved in the hallway. In addition, people often smoke on the landing, the smell no longer gets into the apartment.

As for the appearance, the coating has not changed in six months, no dents or chips. I can definitely recommend.

Normal prices, there are no complaints about the employees, the installers, too, they ordered several doors - everyone received it as ordered - there is a question of choice, not everyone was able to pick up and was a little delayed with delivery, for 5 days, but they say that the transport company is to blame for taking a long time . As a result, everything is ok.

We ordered an entrance metal door from this store at the beginning of June 2015. At first they wanted to buy something very expensive, because, as everyone thinks, if it is very expensive, then it is very good. The consultant offered several models from different price categories, explained the advantages of all and we settled on a more modest door model, but it meets all our needs, so why pay more? Very good employees, it is clear that they want to please, not cash in on the client! big

For a long time my husband and I chose the option of a metal door. Consider the quality and, of course, the price. From the cheap cans”, which are pressed through from an accidental blow, were abandoned immediately. Having studied the catalogs, we settled on ARGUS, the model is called "DA-10 ISABEL". In our opinion, the value for money here is the best. I will not talk about external qualities, this is not for everyone, although I am fully satisfied. First of all, I was interested in the thickness of the steel. Here - 2 mm, which is a huge plus. Also - the quality of the insulation, because it is he who is responsible for noise and heat insulation. Everything is great with this too! Finally, I stopped hearing the noise of the elevator from the entrance. The door closes quietly, smoothly, no special effort is needed. There are two castles.
Delivered on time, ordered doors with installation. The master did everything quite quickly - in about an hour and a half. Accurately, without any nuances.

I am just delighted with such a huge range of doors in the Dok Dor company. It is possible to choose the perfect suitable option. It happened to me as well. In terms of buying doors, I have always been picky, so this has always been a problem. So, I looked through an unthinkable number of sites that sell doors, but I didn’t find anything. But then a miracle happened and I got to the Dok Dor website. Here, too, I carefully looked through everything and surprisingly noted several options. I “rushed” among them for a long time and eventually chose the TRENTO (Top) entrance metal door. It has everything I was looking for, nothing more. As the saying goes "don't give, don't take". This door is just the embodiment of "my ideal door."
Arranged and delivered the order quickly, it is very pleased. I would also like to note the work of the installers, who installed the door very well. Now I just can't get enough of her, she's so good! Thanks a lot!

We ordered the safe-door Argus "DA-6". We got a discount, we are very glad that we were on the site at the right time. The door of fine quality, strong, reliable, not without reason it is called the safe door. The locks are so complex that picking them is simply unrealistic. From the outside, the door looks imposing and very austere, but inside it is very elegant. There is a mirror insert in the center, which is very suitable for apartments with a small hall, like in our house. We still cannot get enough of it, the family is delighted, friends and relatives envy with wide eyes.

Have you decided to replace the interior doors in your apartment or house? Wonderful! Do not want to pay money to third-party installers? No problem! Any interior doors can be installed with your own hands. There is nothing difficult in this event. You just need to figure out the order of work for the doors different types and do everything according to the manual for your case.

Replacement work interior doors begins with the dismantling of old door structures. If your home has "bare" doorways, you can skip this part of the instructions and go to the manual for direct installation of the product.

The dismantling procedure will differ depending on whether you need to keep the old door in its proper form, or whether you simply get rid of it after dismantling.

If the door is no longer needed

First step. Remove the door leaf from the hinges. If the hinges are collapsible, it is enough to simply lift the canvas. Otherwise, you must first unscrew the fixing hinge screws and only after that you can remove the door.

Second step. Dismantle cash. To do this, pry off the platbands with the help of a crowbar and tear them off door frame.

Third step. Unscrew the fasteners that secure the door. If there are no anchors or other fasteners, go directly to the next step.

Fourth step. Break up the foam layer with a hacksaw. To do this, punch a hole in the top layer. polyurethane foam so that a hacksaw can be inserted into the blow, and then saw through the material to the bottom. Repeat the operation on each side of the box. So you can easily get rid of the mounting foam.

In conclusion, it remains only to align the opening before installation new door.

If the door needs to be saved

First step. Remove the canvas from the hinges.

Second step. Get a chisel between the door frame and the casing at the point of fixing the cashing element with a nail. Carefully try to break the nail with a chisel. After the fastener has moved a certain distance, grab it with pliers and pull it out. Remove all nails according to this scheme and remove the cashing elements.

Third step. Remove the box and carefully clean it of any remaining foam. Cut off as much foam as possible with a knife. Apply pharmacy dimexide to the remaining foam. Under its influence, the foam will become soft, and you can remove it.

Swing door installation

Regardless of the material of manufacture, all single-leaf swing doors are installed in the same order.

First step. Dismantle the old door in accordance with the recommendations received earlier. If you wish, you can leave the old box and install a new canvas in it, however, this option should only be considered if the budget for repair work strictly limited.

Second step. Measure the opening or the old box. Usually the dimensions of the boxes and openings correspond to the standard, but it does not hurt to make sure, especially in the case of replacing interior doors in a private house.

If the dimensions do not meet the standard, the box and the canvas itself will have to be ordered according to individual measurements.

If it becomes necessary to cut a box or canvas, it is strongly recommended to do this exclusively in the carpentry shop. When doing such work at home, the slightest mistake can lead to complete damage to the product.

Third step. Determine the opening direction of the new door and the location of the handle. Mark the door frame for installation door hinges. The optimal distance between the lower loop and the lower edge of the canvas is 20 cm, between the upper loop and the corresponding end of the canvas - 15 cm.

The hinges must strictly coincide with the end of the door. Use self-tapping screws to fix the hinges.

Fourth step. Install the door on the fixed hinges. Make sure nothing is preventing the door from opening and closing. Adjust the position of the hinges if necessary.

Fifth step. Remove the canvas from the hinges and fix the door frame in the opening. To do this, level the box, drill mounting holes in it and in the opening surface and fix the product with anchors and dowels.

Sixth step. Hang the canvas back on the hinges and check the result of the work again.

Seventh step. Secure the cashing elements with decorative nails.

In conclusion, you will have to install the door handle. If desired, install a latch or a more modern door lock. In most modern models door handles there are built-in locks. Pre-prepare for them the appropriate recesses in the door frame.

Control the evenness of the installation of structural elements at each stage of work. Get rid of all defects immediately, because. in the future, they can lead to serious problems and inconvenience.

Installation of a sliding door

First step. Dismantle the old door in accordance with the previously received recommendations.

Second step. Align all gaps carefully. It is important to get rid of all existing cracks and other defects.

Third step. Make a groove from the side of the bottom end of the panel. A chisel will help you with this. Then put the guide in the form of the letter “P” into the finished groove and fix it with high quality. The rollers of the mechanism will move inside this guide.

Fourth step. Insert the rollers into the fixed bar.

Fifth step. Place the door on the track while attaching it to the sliding rollers. To do this, you need to bring the canvas into the grooves of the rollers. This operation is more convenient to perform with an assistant. One holds - the second exposes the door.

Sixth step. Determine and mark a suitable location for the top rail. Check the bar below. The top bar must be placed in the wall above the opening.

Seventh step. Attach a metal guide to a timber beam. Fix the bar with the guide with anchors to the upper end face of the blade. Check with a level that the door is correctly installed. It is important that the bar is placed in a horizontal position. Otherwise, the doors will close and open without your participation.

Eighth step. Install the door leaf. First, set it vertically and tilt it slightly in the opposite direction from you. Next, you need to bring the upper rollers to the appropriate guide, then slightly raise the canvas and bring it to the bar below, while installing it on the movable rollers.

Ninth step. Install stops that will not allow the blade to fly out of the guide bars. Install handles. Hide the top rail with a casing. To fix the platband, use self-tapping screws or decorative nails.

Check the correct operation of the door. The canvas should move smoothly and gently. Eliminate any defects immediately after their discovery, without delay.

First step. Get rid of the old door if you have one. Align the walls of the liberated opening - differences are unacceptable. Very easy to use for alignment. wooden planks. Nail the boards in the recesses, cut them off on the ledges.

Second step. Measure the free opening and calculate the required number of panels to assemble the door.

Third step. Cut the side profile so that its length is 25 mm less than the height of the opening.

Fourth step. Cut the panels so that their length is 40 mm less than the height of the opening.

Fifth step. Assemble individual panels into a single structure. It is most convenient to do this on the floor.

Place special panels with channels on the sides - a fixing bar on the left, a locking bar on the right. To connect the elements, use the end strips. Stoppers will provide additional fixation. Pre-make a couple of holes for the magnetic latches on the lock plate and mount the latches.

Sixth step. Prepare axial marks on the left side of the upper end of the slats. Make holes according to the markup.

Seventh step. Insert axes. After installation, their ends should extend beyond the ends of the panels.

In the design of different "accordions" there are often certain differences. If your door structure is equipped with runners, then holes for the axles do not need to be drilled. In this case, the sliders must be screwed to the end faces of the panels. Start fixing the sliders from the lock panel and fasten through one bar.

Eighth step. Cut the guide bar to fit the width of the opening. Set aside a third of the length of the guide and drill a hole for the screw at the marked point. Fix the guide with a screw.

Ninth step. Install the sliders in the guide bar, after lubricating them.

Tenth step. Align the guide with a level and secure it with the second screw.

Eleventh step. Lock the side guides. To one of them you need to fix the clip of the side profile, to the second guide attach the plates of magnetic latches.

This completes the installation of the accordion-type interior door. Check the quality of installation, make sure that the door moves smoothly and evenly. If problems are found, fix them immediately.

Work, as always, start by dismantling the old door, if present. Align the walls of the opening and proceed to the main stages of work.

First step. Assemble the door frame. For assembly, use boards about 10 cm wide and about 6 cm thick. To fasten the boards, it is most convenient to use the usual tenon connection. The connection angle must be exactly 19 degrees.

Second step. Fasten the aligned box in doorway. Pre-drill mounting holes in the wall, and then fix the structure with pins or thick nails.

Third step. Make sure that the dimensions of the door panels correspond to the size of the box. If necessary, cut the end sides of the canvases to the required size.

Fourth step. Fasten the loops in the appropriate places. Determine in advance which way it will be more convenient to open the doors.

Fifth step. Hang the door panels on the hinges. Install the handles and check the quality of the work done.

Thus, there is absolutely nothing complicated in self-replacing interior doors. By understanding the basics of the guides presented, you will be able to handle all the upcoming events without the involvement of third-party specialists. This will allow you to save additional money and be completely confident in the quality of the installation.

Often the beginning of the repair is marked by the fact that you need to replace the front door to the apartment.

Scheme of the device of the iron entrance door.

Having bought a new box and entrance doors from a trusted supplier, you can start dismantling the old ones.

Required Tools

Necessary tools: level, hammer, perforator, Phillips and flat screwdrivers, masking tape, grinder with a disc for metal.

Replacing the front door will require some tools. Among them:

• mount (crowbar);
• masking tape (if there is no protective film);
• dowel-nails (12 cm long and 1 cm in diameter);
• drill (15 cm long and 1 cm in diameter);
• spray bottle with water;
• hammer;
• level;
• mounting foam;
• perforator;
• hacksaw for metal;
• screwdriver;
• expansion wedges;
• Phillips and flat screwdrivers;
• grinder with a disk for metal.

Before work, you should take care of protection - wear gloves and goggles.

Removing the front door

Scheme of installation of an entrance door under a semicircular platband with finishing of the doorway with additional elements and a platband.

Before replacing the front door, you will need to dismantle the old one. In this case, it is necessary to remove not only the canvas, but also its other elements.

The design is removed quite simply. If the door leaf is attached with collapsible hinges, then the following method is applied. To begin with, the door opens at an angle of 90 degrees. If there are no necessary skills, this process is best done together. One slips a crowbar or pry bar under the bottom of the door closer to the side where the hinges are located. His partner must hold the canvas itself until it can be removed and it does not completely come off the hinges.

If the door was fixed with one-piece hinges, then here it is necessary to unscrew them from the door leaf or box with a screwdriver or screwdriver. The same is done when the detachable hinges are rusted or warped. If the tools do not help, then they are cut off by a grinder. Instead of a mount, any other tool is also suitable, such as a screwdriver, reinforced with a support on a bar.

Next, the wooden box is dismantled. Before that, the plaster is beaten off from the side of the room. If it is found that the door is recessed from the side of the room, then the plaster is beaten off in places of slopes.

Scheme of the arrangement of doorways.

If the door is on the same level as inner wall, then the plaster is beaten up to 15 cm wide from the edges of the opening. If the box was foamed at one time, then the foam is cut off along its entire perimeter.

Then, using a hacksaw, one of the racks is sawn and removed with a mount. After that, the upper part remaining from the side rack is dismantled. Then remove the upper and lower crossbars and threshold. Carefully remove the remaining parts of the rack. All fasteners used - self-tapping screws, anchors and nails - are pulled out and unscrewed in advance. If difficulties arise at the same time, then they are easy to solve using a grinder or a hacksaw for this purpose. If there are protruding metal parts, then it is easier to hammer them into the wall. Old plaster will come off during work. It should be cleaned, freeing the perimeter of the opening from it.

If the doors were installed on a box made of metal, then the work will definitely not be easy. It was probably fixed by using welding for this purpose. Therefore, for work you will need a grinder, which will have to cut off the welded rods.

At the end of the work, the opening is cleaned of the resulting debris: mortar, pieces old plaster. It is possible that this will require a hammer.

Having completed the dismantling, they install the front door. It is divided into the installation of the box and the door itself.

There are 2 mounting options, depending on a number of parameters:

• installation level of the new box in relation to the opening;
• place of installation: apartment, house.

Types of entrance doors.

The installation itself is carried out thanks to wedges-bars cut at an angle. They are hammered between the box itself and the wall or floor (or ceiling). An old box makes great wedges! It is very important that the technological gap is the same on all sides.

The insertion is carried out so that the level on the "thorn" demonstrates the "horizon". It is applied to the side rack with loops on both sides. For a door made of metal, a magnetic level is very convenient. Its length is 400-800 mm. At the same time, for a shorter length, the level will give an error, for a longer one, there will be problems with the horizontal alignment. Indeed, in apartments, the width of classic doors is 900 mm.

The eyelets must be strictly vertical. On each of them place 2-3 anchor bolts.

Having determined the required horizontal and vertical, the box is carefully fixed to the mounting plate installed at the top hinge.

Mounting Option #1: Features

Scheme of installing the front door under a flat casing.

The standard option for mounting the box is in its fastening with mounting plates. Usually they are installed in 3 pieces along the length of the side racks.

They are applied from the side of the room to the walls of the opening. Therefore, the inside of the door is set flush with the wall.

Further, reinforcement or bars made of metal, whose diameter is 12-16 mm, are hammered through the holes in the plates. Subsequently, if there welding machine, they are welded to it or riveted, otherwise anchor bolts are installed. In addition, they greatly simplify the installation and future dismantling of the box. Dowels-nails are also used. For them, holes are drilled in the wall with a puncher.

In this method, it is required to leave a gap of 1-2 cm between the wall and the sides of the door frame. This mounting option is used for a private dwelling. However, if the wall thickness allows, it can be used in an apartment.

The option is used when it is possible to drown the door in the opening. Doors in this case are located far from the edge of the opening, and the plates will not help. This option is used if the wall has the required thickness of 150 mm or more. If it is smaller, then attackers can easily pull it out.

The box is fixed with anchor bolts through the holes made in it in advance.

The scheme of using a multi-color stencil for decorating entrance doors.

After screwing in, plugs are put on them, painted to match the color of the box being installed.

If the box is without ready-made holes, then they are drilled. After that, it is fixed with steel rods, which are hammered into the wall through the holes made in the box. Further, thanks to the welding process, they are tacked from the inside. To carry out this process, a gap of 0.5-1.5 cm is left between the box and the opening on both sides.

When installing, sometimes both of the above methods are combined. Bolts and metal bars are used in this case with a length of 10 cm and a section thickness of 1-1.5 cm. Bolts are used to mount a box made of wood.

Direct installation of the door to the apartment

The insertion of the canvas is carried out upon completion of the installation of the box in the opening. Its installation is the same for doors from different material. Door alignment is carried out from the side of the rack with hinges. To do this, use a plumb line or, alternatively, a building level.

Further, holes are drilled through the mounting plates. To do this, use a puncher or drill. The diameter of such holes is 1.5 cm, and the depth of the hole varies between 10-12 cm. Pins (anchor bolts) are inserted into them. Everything is re-checked by level. This is necessary to make sure that the box does not move during the drilling process. Next, weld or fix the bolts.

Door hinges are lubricated with engine oil and balls are put into them when their design provides for it. After hanging, the part of the lubricant that has come out is carefully removed. Close the door with pre-installed fittings.

In this case, it is required to make sure before the final fastening that the door can move without effort, and the fittings work properly. Using these instructions, the replacement of the front door will be carried out quickly and efficiently.
