It's no secret that the final stagerepair in the room is the installation of interior doors. New doors should replace the old ones, giving the entire room an updated look. They should match the appearance of the room and be in harmony with its furnishings. Moreover, modern interior doors not only separate the living areas of the house and decorate the interior, but are also able to provide good sound insulation and maintain a comfortable temperature inside the room. They are made of solid wood, which can be additionally covered with wood veneer, or from modern artificial material MDF. Doors can be blind or have glass inserts. The color of such a door can be any, so choosing the right one is not so difficult. In addition, without resorting to the help of hired specialists.
Installation of interior doors.
Necessary tools, supplies and preparatory work
Before you start installing a new door, you need tofree the doorway from the old one. The door leaf is simply removed from the hinges and removed from the room, and the door frame is removed extremely carefully so as not to damage the adjacent internal partition. To do this, it must be sawn with a grinder and removed in parts. Then you need to clean the opening from the remains of the solution and old fasteners. It remains to adjust it to the size of the new frame. This size is determined by adding the width of the door leaf, the thickness of the frame posts and the gaps for free opening of the door and for placing the mounting foam.

For the door to move freely, there should be 2 mm left between it and the side post on each side and the same amount on top, between the door leaf and the crossbar of the frame. To leave room for the mounting foam, 2 cm should be left on each side between the outer edge of the posts and the adjacent wall. If there is not enough space, the opening can be easily widened with a hammer drill. If it is too wide, it can be narrowed by installing inserts made of wooden beams. Usually, the parts for the door frame come complete with the door leaf, but they have to be adjusted to size on site. In order for the installation of interior doors to go smoothly and without any particular delays, you need to purchase consumables and prepare the necessary tools in advance. The materials you will need are anchor bolts, wooden or plastic wedges, metal fastening plates for the profile, self-tapping screws, mounting foam and gypsum putty. The tools you will need are a wood saw, a chisel and a chisel, a cordless screwdriver, an electric drill, a tape measure, a building level and a plumb line. Only when you have all of this at hand can you begin installation. Return to contents</a>
Mounting the door frame
Door frame installation diagram.First, measure the required length of the side posts and the crossbar. Then use a hacksaw to cut them so that both ends of the crossbar and the upper ends of the side posts have bevels at an angle of 45º. The bevels of the side posts should be directed towards each other. Then, fasten the side posts and the crossbar together with screws, for which you need to pre-drill holes so that the wood does not split. Hinges are attached to the door leaf itself, stepping back 20 cm from the lower and upper edges. To install them, grooves are made in the leaf with a chisel and a chisel. If the side is covered with veneer, it is first cut along the contour with a package knife. Each of the hinges is attached with 4 screws. After their installation, the door is inserted into the assembled frame, mark and gouge out the same grooves for the hinges on one of the side posts. In this case, you must not forget to observe the necessary gaps. At this stage, you must first decide in which direction the door will open. Return to the table of contents</a>
Installation of the assembled box in the opening
The gap between the doors and the frame.It is worth mentioning that there are two ways in which you can install the door into the wall opening. This can be done as a whole block, when the door is already fixed in the frame, and separately, when the frame is first fixed, the trims are mounted on it and only at the end the door is hung. The first method saves a lot of time, but is much more complicated and requires a lot of effort, so for self-installation it is better to choose the second method. The assembled frame is carefully lifted into the opening and secured with wedges, which are driven between its outer edge and the adjacent edge of the wall every 20 cm. In this case, the position of the crossbar is aligned with a level, and the side posts - with a plumb line. After this, through holes are drilled in the posts and crossbar at a distance of 25 cm from each other, into which anchor bolts are inserted. They enter the wall by 10-15 cm, securely fixing the frame in a given position. The bolt heads are hidden in secret recesses, which are sealed with putty after the door is installed. After that, they are sanded with sandpaper and the posts are painted. If the interior doors are veneered or made of MDF, the use of anchor bolts is very difficult. It is very difficult to hide traces of installation on the surface of the posts of such a door, since it does not need painting. The only place where you can make holes for bolts is the grooves for attaching the door hinges, since they will be covered from above. On the opposite side, this is the place to install the back plate of the door lock. Meanwhile, MDF posts are prone to bending much more than those made of solid wood, due to the properties of the material itself. If the post begins to bend outward from the door opening, it is leveled by hammering a spacer wedge in this place. If it bends inward, it is first leveled and then fixed with a metal fastening plate for the profile. Return to the table of contents</a>
Final work
After installing the door framethe doorway is successfully completed, the door itself is hung and checked to see how freely it opens and closes. If there is no rubbing anywhere, the gaps between the outer edge of the door frame and the wall are filled with mounting foam. Before this, the door is covered with polyethylene film, and the frame with tape, since the foam can leave stains on their surface. After it has completely hardened, excess drips are cut off with a bag knife. Then the door frame can be attached. It, like the side posts and the crossbar of the frame, is measured with a tape measure and cut with a hacksaw, leaving the end at an angle of 45º, and attached over the frame on both sides of the door. All that remains is to install the door handles and the lock. In this regard, interior doors are practically no different from entrance doors. The lock can be either mortise or overhead, and for its installation you will need a drill, chisel, chisel, hammer and screwdriver. Installation of interior doors usually involves a combination lock with a handle on a latch. In general, it can be noted that the installation of interior doors is an operation, although quite complex, but quite feasible to do with your own hands. You just need to do everything carefully and follow all the above recommendations.
