Interior doors can become damaged, difficult to operate or old-fashioned compared to the rest of the décor. Replacing an interior door is a one-day project for one or two people.
Step 5: Fasten the frame into place Set the door frame evenly in the opening. Use a level to get the frame plumb on the hinge side. Use shims or wedges between the frame and the studs to adjust the hinge side of the frame until it is both plumb and square. Near the hinges, drive 10-penny finish nails through the frame, the shims and part-way through the studs, but do not drive the nails all the way in. Repeat the process on the other side of the door, opposite the hinges. Position shims or wedges until this side is plumb and level, and drive 10-penny nails through the frame, shims and part-way through the stud. Check that the entire frame is square and plumb, and then drive the finish nails until they are nearly flush with a frame. Counter-sink each nail with a nail set. Drive a 10-penny nail into the frame, shim and stud.
