Preparing to install the new door
First of all, you have to make sure the door opening is clean of residues and it is prepared to install the new door. If you want to replace an existing door, then you have to remove it together with the door frame and jamb. This job is pretty difficult for an unexperienced diy-er, so you could either hire a qualified professional or ask a skilled fried to assist you.
After you have removed the old door, you have to use a tape measurement to determine the width of the door opening and the distance between the bottom sill and the header. In this way, you will be able to buy a new door which will fit your door opening.
Installing the pre-hung door
If you have bought a pre-hung door, then in most of the cases the hinges are already installed. Nevertheless, if they aren’t, you should use 2” wood screws and an electric screwdriver to fix the door hinges to the jambs.
Next, you should position the frame and the door inside the opening, of course with the help of a fried, as they are quite heavy. Next, move them until you find the perfect fit. Make sure you have left a clearance space between the door and the floor, otherwise your door wont open – you could make sure the space will not decrease during the process by using 2 spacers (1/2 – 1”).
Afterwards, use a spirit level, to check if the door is aligned properly. Use the level on the side jambs, on the head jamb and on the door itself. If the frame is not aligned properly, you have to install door shims to correct the alignment.
Install the door shims in the place where the door is not leveled. In order to obtain a perfect result, you should use shims of different dimensions until you notice the frame is aligned properly.
Next, you should use a piece of timber to make sure the polyurethane foam will not push the frame off its position. Consequently measure the distance between the door jambs and cut a piece of timber at that length minus 1/2”. As to protect the door frame from scratches, you should install two pieces of cardboard at both ends of the piece of timber.
After you have locked the door frame into position, you should make one last check. Just close the door to see if the space between the door and the jamb is even from top to the bottom. If the gap is uneven, then you haven’t installed the shims properly, consequently you have to redo the whole process until you notice the alignment is right.
Next, it is time to install the door permanently, using polyurethane foam. Consequently, use the polyurethane foam to fill the space between the walls and the door jambs. Do not use too much foam, as it expands and it could damage the alignment of your door, but if you have followed our previous guidelines it should turn out good.
Continue applying the polyurethane foam around the door jambs, making sure you do not move the door from its place, otherwise your hard work would be for nothing. Fill the space between the concrete wall and the door jamb with foam, as to obtain a even layer around the whole perimeter.
Remember that before applying polyurethane foam you have to make sure the door is level and it opens properly. In addition, it has to be aligned with the walls of the room, as to be able to install door trims. This aspect is essential, otherwise you would end up with an unpractical door. Last but not least, the door should be fixed firmly in the door opening, using the shims. If the door is not locked into position, it could slide or even injure someone.
After you have finished applying the polyurethane foam around the whole perimeter of the frame, you should close the door, as to make sure the center of gravity is aligned with the door frame. In this way, the door will stay on its position and you won’t face any issue with it, after the foam dries out.
Usually, you have to wait at least one day until the door could be opened and the shims and the two pieces of timber removed. Consequently, do not try to use the door until the polyurethane foam dries out completely. Even if the exterior of the foam looks dried out, we ensure you that it has not dried out completely. Therefore, wait just one day until you can use the door at your will.
