Over time, you may notice that some of the interior doors in your home do not operate as they should. The door frame can come out of alignment due to the house settling, or the hinges can come loose from the door jamb. You can adjust the hinges on your interior door to get the door to hang correctly in the opening. Most interior doors use two-piece hinges, each with a pin connecting through sleeves. Small adjustments to door hinges can make a big difference in the operation of your interior doors.
Open the interior door and inspect the three hinges. Look where the pins insert into the leaves of each hinge to ensure that each pin is fully inserted. If any pins rise above the hinge, tap their heads with a hammer to fully seat the pins. When pins come loose, the door will shift.
Inspect the screws securing the hinge to the door and the door jamb, checking for missing or loose screws. Continual use over time can cause screws to become loose and fall out, causing alignment problems. Tighten any loose screws with a Phillips-head screwdriver. Replace missing screws as necessary.
Operate the door and watch the hinges closely. Look for any hinge that appears to lift off the door jamb slightly. This will most often be noticeable on the centre or top hinge. Remove the centre securing screw on the hinge that is lifting away from the jamb, using a Phillips-head screwdriver. Insert a 4-inch wood screw in the middle of the hinge to secure the hinge to the door jamb. Tighten the remaining two screws.
Open and close the door while checking the alignment of the latch bolt to the strike plate to determine if the door needs raising or lowering. To raise the position of the latch bolt, remove the screws securing the lower hinge to the door jamb. Insert a piece of cardboard (the size of the hinge leaf) between the hinge and the door jamb. Secure the hinge to the door jamb with the retaining screws.
Remove the screws securing the top hinge to the door jamb, if the position of the latch bolt needs to be slightly lower. Place a piece of cardboard between the jamb and the hinge. Secure the top hinge to the jamb with the retaining screws.
