Door won't latch or close properly
Tools: screwdriver, metal file, chisel, lipstick or marker, drill · Materials: longer screws (75 mm) for the hinge, wood filler
Steps
- Close the door slowly and watch the latch: mark where it hits the strike plate with lipstick on the latch bolt.
- If the latch hits above or below the hole by a few millimetres, file the strike-plate opening in that direction.
- If it is off by more, the door has sagged: replace the top hinge's centre screw with a 75 mm screw driven into the framing to pull the door up.
- If the latch does not reach the plate, move the plate out with a shim of cardboard behind it, or chisel the mortise deeper if it is too far in.
- Tighten every hinge screw; fill stripped holes with glued matchsticks or filler before re-driving.
Stop and call a pro if
- the frame itself has moved — cracks above the door or a gap widening at one corner
- it is an exterior door with a multipoint lock that no longer aligns
- the door is warped so the top and bottom cannot both touch the stop
What a pro does that you can't
A handyman or carpenter re-hangs a sagging door, adjusts or replaces multipoint hardware, and squares a frame that has shifted with the house.
DIY cost: $0–10 for screws and filler
