Whether your front door has been damaged or is just getting old and drafty, you may want to look into replacing it yourself. It isn't very difficult, especially if you have help. Replacing the door on your own will save you the cost of hiring someone else to do it.

Step 1: Purchase Your New Door

Before you go out to purchase your new door, it is very important that you take accurate measurements of your current door and your door frame and opening. If your current door is drafty, keep that in mind for when you talk with the store representative.

Once you have taken the measurements, take them to a home and garden store or a hardware store to purchase a new door, keeping in mind all the upgrades you wish to have.

Step 2: Remove the Old Door

Take a hammer and carefully tap the pins our of the door hinges. Once they are high enough from the hinge, remove them and carefully take the door off the hinges.

    Then, use a screwdriver to unscrew the the screws from the hinges in the door jamb and remove the jamb from the door.If it is it seemingly impossible to remove the door jamb manually, use a circular saw to cut into it and remove it that way.

    If you want to remove the molding from the old door, use a pry bar to clear it off.

    Step 3: Prepare for Installation

    With a friend's help, lift the door into place and make sure that it fits the space between the door frames. You may also want to simulate it moving to make sure it doesn't hit anything in the way. If the door is level, and the door frame is how it should be, place shims (small pieces of scrap wood) between the walls of your home and the door frame. This will prevent any shifting that may occur while you are installing your door.

    If any part of the frame are not in alignment, place a shim behind the area and using a hammer, nail a finishing nail through the frame and the shim. You can also make sure your door is secure by nailing finishing nails through the rest of the frames and shims.

    Step 4: Install

    Once you have finished your simulation, caulk the bottom of the opening and place the door frame or the threshold into place.

    Before you put the trim onto the door, you may want to paint or stain it so that it matches both the interior and the exterior of the rest of your home. The best way to do this without making a mess is by laying them out on newspaper and painting them with brushes.

    Once the trim is ready to be attached to the opening, you will want to place insulation between the door jamb and the wall's opening. Then place the door back into the frame, to make sure it hangs correctly at about midway through the opening.

    Step 4: Replace the Door's Hardware

    Make sure that the hinges are in place, and attach the door to the jamb.
