Once satisfied, reinstall the door molding. If you used new door shims during correction, score the excess with a utility knife and snap it off.
Remove the door frame (optional). If the door frame is far too warped for correcting (such as through large scale water damage), you will have to replace it. Once the molding and screws are removed, use a crowbar to slowly pry the frame from the wall. Start at the bottom and work your way up. Once the frame is nearly removed, remove it from the top plate by pulling it away from the door with your hands. Remove any shims you encounter along the way.
· You may need to gently move the frame back and forth to nudge the frame loose from the top plate.
Repeat the process for each side of the frame you are replacing. If you are only replacing one side of the door frame, you may leave the top plate and healthy side of the door frame.
· The door will have to be removed from the door frame if you are replacing the part of the frame containing the hinges.
