How to Adjust a Hinged Door

View the edges of the door when it is closed position to determine if there are gaps between the door and the frame. Compare the door to the frame, using a level, to determine if they are both level and square. Note the areas that have gaps or appear to sag.

Tighten all the screws in the top hinge if the door seems to sag. This should tighten up the connection and raise the top of the door to make it level. Check the screws on the other hinges to see if they also need tightening to get a better fit for the door within the frame.

Fill in the screw holes if they are stripped and won't allow you tighten the screws. Dip a matchstick, toothpick or similar small piece of wood in carpenter's glue and place it in the hole. Cut off the end of the stick with a utility knife once the glue dries.

Drill the holes again and install the hinge with screws. Replace at least one of the screws on each door with a longer screw that extends beyond the doorframe and into the stud beside the frame.

Adjust the door's alignment in the frame by adding shims behind the hinges. Cut thin cardboard to fit under the side of the hinge that attaches to the doorframe. Place the cardboard behind the hinge and screw it in place.

Sand or plane the hinge edge of the door or the top of the door if you need to make additional adjustments because the door sticks. Take off only a small amount at a time so you don't remove too much and cause more gaps or closing problems. Paint or seal the edges with polyurethane so the exposed wood from sanding or planing doesn't become damaged.
