A door contractor measures openings, removes old doors and frames as needed, installs and levels new doors, adds thresholds, trim and weatherstripping, and fits hardware. Many also repair and adjust existing doors.
Replacing only the door slab can work when the frame is square and in good condition. A prehung door, which includes a new frame, is often better when the frame is damaged, rotted or out of square. A contractor can check the opening and recommend an approach.
Look for experience with the door type you want and ask what the price includes, such as the frame, trim, hardware, painting and haul-away. For exterior doors, ask how the installer will flash and seal the opening against water.
Cost depends on the door type and material, whether it is prehung or a slab, glass or sidelights, framing changes, trim and finishing, hardware and access. Custom sizes and enlarged openings add labor.
Clear the area on both sides of the door, remove nearby decor and plan for the doorway to be open during part of the job. Decide on hardware and finish beforehand, and keep pets secured while the opening is exposed.
