Use a spirit level to check if your door is level and adjust the position of your wedges as required. Then put the top screw into the bottom hinge. Remove the wedges and check the door shuts properly. If it's not right, undo the bottom hinge, alter your wedges, rescrew and check again. Once the door shuts properly, screw the hinges down fully and the job is done. In this case, the doorway was a little wide at the bottom, so we used a wrecking bar behind the jamb to “ease the door” out a little.
