Doors that stick, slam or will not latch: humidity plus air conditioning
UAE doors misbehave for two local reasons. First, humidity: timber doors swell through the humid months, roughly June to September on the coast, and a door that fit perfectly in February starts scraping its frame in August. Second, air pressure: a closed apartment with the AC running sits at a slightly different pressure to the corridor, which is why doors slam themselves or refuse to close that final centimetre. Diagnosis comes before tools: a pro closes the door slowly, watches where the gap tightens, and checks the hinge screws before assuming the door needs planing.
Nine times out of ten the fix is at the hinge. Years of use strip the top hinge screws out of the frame, letting the door drop and bind at the latch corner. The repair sequence is: remove the stripped screws, plug the holes with glued hardwood dowels or fit longer screws that reach the wall structure behind the frame, and re-hang. If the door still binds after the hinges are true, then and only then does the plane or belt sander come out, taken to the bottom or latch edge in light passes, with the bare timber resealed afterwards so it does not just swell again next summer. Latch problems usually need nothing more than moving the strike plate a couple of millimetres.
