How to Fix a Door Jamb
- 1). Remove the door by using your chisel and hammer to pop up on the hinge pins. Start with the bottom hinge and move upward. Put the pins back into empty hinges, and set the door aside.
- 2). Move the loose jamb to its correct position so it's lined up right on either side of the doorway. With your drill and 1/8-inch bit, drill two holes into the face of the jamb about 6 inches from the top. The holes should be on a horizontal plane with one another, with one positioned in the center of the 2-inch vertical span that holds the hinges, and the other an inch from the other side of the jamb. The raised trim door-stop should be between the holes.
- 3). Move down the jamb with your drill, putting additional pairs of holes about every 2 feet and one last pair 6 inches from the bottom. Repeat the process on the other side of the jamb and on the top piece, (drilling upward).
- 4). Switch your drill to a screwdriver bit. With your wood screws, go back to each of your starter holes and sink a screw until the head goes just below the surface. Don't tighten more than that. You just want to secure the jamb to the door frame without moving it outward.
- 5). Once you've set all the screws, go back over each one and, with your thumb, wipe a dab of caulk over the sunken screw head, smoothing it flat. If you don't have the same color caulk as the jamb, then wait a day for the caulk to dry and repaint the jamb. Put the door back on the hinges with the pins.
