A door that won't close or latch properly can be annoying. This guide covers diagnosing and fixing the issue.
Step-by-Step Fix
Safety & Preparation
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- Begin by inspecting all screws on both hinge leaves attached to the door frame and the door itself. Tighten any loose screws firmly with a screwdriver to ensure the hinges are securely fitted and not allowing the door to sag.
- Open the door and visually check if the latch bolt on the door aligns perfectly with the hole (mortice) in the strike plate on the door frame. If the latch is hitting the plate above or below the hole, this is your primary problem.
- If the strike plate and latch don't align, carefully unscrew the strike plate from the door frame and gently reposition it upwards or downwards as needed. Screw it back into place, ensuring the latch now enters the mortice cleanly, then test the door's closing and latching action.
- Should the door be catching or sticking against the frame, identify the exact point of contact by closing the door slowly. Carefully remove the door from its hinges if necessary, then use a hand plane to shave a small amount of wood off the sticking edge, working slowly and checking the fit frequently until it closes smoothly.
- Examine the door for any visible signs of swelling, especially along the edges, which often occurs due to moisture absorption in bathrooms or kitchens. If the door appears swollen, allow it several days to dry out in a drier environment before considering further adjustments, as the swelling may recede naturally.
- If you've tried all the above steps and the door still won't close or latch correctly, it's best to contact a qualified local carpenter. They can provide a professional diagnosis and carry out more complex repairs, ensuring the job is done safely and effectively.
