Before you buy a door, make a measurement of the doorway.

If the installation of the door will be handled by specialists who make the entrance doors to order, they will make all measurements correctly.

And if you want to buy a ready-made door and install it yourself, you should know that the door leaf must be 20-25 mm narrower than the opening, or the door frame near the new door, should be already 40-50 mm in size and lower in the 40- 50 mm than the opening.

Dismantling the old front door

Before installing a new door, it is necessary to remove the old one.

If the old door hangs on the hinges, under the door, wide open, bring the mount or crowbar and raise the door until it exits the hinges.

If the hinges are all-in-one, then holding the door, unscrew the hinges with a screwdriver and remove the door leaf without problems.

After removing the door leaf, grasp the removal of the door frame.

If the box is wooden, it is usually fastened with screws or nails.

Screw out the screws with a screwdriver, remove the nails with a nail.

Do any further work with a nail or mount.


Since the parts of the door frame can not be applied anywhere else in the future, you can not especially avoid it.

And remove all the parts of the path.

Professionals, sometimes, saw the side parts of the door frame and thereby speed up the work.

And if the old box was metal, and the metal is attached using welding or metal pins, you will need an electric Bulgarian for metal, goggles or a mask.

After removing all the fasteners, a metal box is pulled out.

Installation of a door box, a step-by-step course of work

The door box is attached using mounting plates with holes in it and a metal pin is driven into it, which is welded to the door unit or a metal anchor is screwed in.


The second way of fastening the metal box, using anchor bolts, the box is attached through holes, or through holes, located directly in the door frame.

We begin to install the door box in the doorway:

-to the aid wooden wedges which can be prepared by an ax from a tree are required. Wooden wedges fix the top and bottom of the door frame;

- in each concrete fixing point use two wooden wedges, constantly check the horizontal and vertical with the help of the building level;

- After placing the box horizontally and vertically, we take anchor bolts or pieces of reinforcement, we take a perforator in the mates and through the box drill holes in the wall to a depth of 12 cm;

- We drill pieces of reinforcement into drilled holes or screw anchor bolts;

-all strengthening works begin at the hinge side;

- once again check the level of the vertical and horizontal and if everything corresponds to the norm, make a final tightening of the nuts of the anchors;

-If you use pieces of reinforcement, after the armature is hammered, check the level and secure with welding;

- At the end of the fastening of the door frame, you can hang the door leaf on the hinges and again check the level of the horizontal and vertical of the entire structure.

Door installation, final stage

If everything ended safely, proceed to the final stage. The next stage is to adjust sound insulation and thermal insulation, i.e. fill the gap between the door frame and the wall.

If you use foam, remember that it expands 1.5-2 times. Having blocked the cracks, after 12-24 hours, clean the surplus with a sharp knife. And if you want to make a more solid structure, fill the slots with cement mortar.

In this case, do not just cover the cracks, but inject the cement slurry into the opening.

After the slots have been smeared or blocked, install door slopes.
