How To Replace and Install an Interior Door

If you have an interior door that is damaged and worn, it may be time to replace the door. For this project you will need a replacement door, hammer, screw, tape, pencil, a combination square, saws clamps, chisel, door lock installation kit, drill bit, level, circular saw and new hardware. Before we remove the old door make sure you measure the width and height of your old door. Getting started, unhinge the door. Set the old door on top of the new door on the saw horses. Unscrew the hinges, door locks and knobs. Make sure the doors are flush on the top and hinge sides. Use clamps to hold them in place. Next determine the location of the knob, locks and hinges from our old door and transfer that information to the new door. In most cases, you will need to mortise the hinges on the new door. Line up a combination square with the hinge mortise. Mark the top and bottom of the hinge mortise. Mark the other hinge as well. To determine the depth use the existing hinge and mark its depth. Next, mark the lockset location. Make sure that there is no overhang with the new door vs. the old door. If so, mark where you need to saw off the overhang. Now that the doors are cut to size, remove the old door and start to cut the mortises' for the hinges. Use a hammer and chisel to remove the wood. Once you have done this, mark pilot holes. For the lockset, you can use a door lock installation kit. Line up the jig, screw in the screws, and drill the hole into the lockset. If you are going to paint your door, this is a good time to do so. Next attach your hinges to the new door, along with the new hardware you have purchased. On the door frame remove the old hinges, and attach the new ones. If the mortise isn't deep enough, make it deeper by using a chisel and removing some wood. If it is too deep, cut a piece of card board and apply behind it. Now attach your door, and insert your pins. There you have it, a new door in just a few steps.
