- Start by figuring out why the door is sagging; often it's only a loose screw. Lift up on the sagging door to position it properly and tighten the screws holding the hinges in place. Most of the time the loose screw will be on the top hinge, so start by tightening that one, then tighten the rest of the screws as well.
- If retightening the screws doesn't fix the problem, try replacing the screws with longer or wider screws, making sure they will fit into the openings on the hinges.
- If new screws don't fix the problem, the hole is stripped and needs to be repaired. Take the cupboard door completely off the cabinet by removing all the screws. Put the screws into a small plastic bag and tape it onto the backside of the door so you won't lose them.
- Put wood glue into the screw holes, then put the toothpicks or matches in. Wipe up any overflow glue that comes out of the holes and allow the glue to dry, usually overnight, but follow the instructions on the bottle.
- Once the glue has dried, use a utility knife or small saw to cut the toothpicks off flush with the surrounding cabinet frame.
- With the help of another person to hole the door and the hinges in place, mark the position of the screws.
- Drill small pilot holes (smaller in diameter than the screw) to ensure a tight fit after installation, then holding the door onto the cabinet, install the screws.
- Hand tighten the screws to allow yourself to make any small final adjustments to the position of the door.
Things You Will Need
- Wood glue
- Utility knife
- Wooden toothpicks or wooden matches (heads removed)
- Power drill
- Toothpicks, and perhaps even matches, are handy around most houses, but they are made from soft wood and over time may give out. Instead, you could use pieces of thin hardwood dowel to provide a more permanent fix.
