Adjustment before replacement in recent homes
A flat door fitted new arrives properly adjusted. It then moves: the building settles during the first year, the weather seal compresses, the hinges take up play, and the top point of the multipoint lock ends up catching. You recognise the situation by a gesture that has become familiar, lifting the door slightly or leaning on it in order to lock up. It is not the lock that is at fault but the alignment, and carrying on forcing eventually distorts the rod linkage.
On a shielded multipoint lock, the temptation to lift the cover and see what is catching is a poor guide: the rod linkage is under tension and refitting it calls for precise adjustment, point by point. Another reflex to avoid is general-purpose penetrating oil sprayed into the keyway, which leaves a greasy film that attracts dust. Finally, in a recent building it is worth asking the syndic whether other homes in the block have reported the same symptom.
Gates, garages and service doors on the edge of the marshes
Bruges lives alongside an area of marshland and jalles, and the air stays damp for much of the year. The most exposed locks are not those on front doors but the ones that live outdoors: gate lock case, side gate cylinder, garage door lock, garden shed padlock. They take the rain, the splashes of soil and the swings in temperature, and the first sign is a key that catches.
In the houses of the old centre, it is the timber that dictates. A solid timber door swells with the damp, rubs against the strike plate in winter and regains its clearance in summer; the lock takes that strain all year round. The right reflex is to deal with the alignment, a strike plate to reposition and hinges to reset, before concluding that the mechanism needs replacing. A new lock fitted to a door that rubs will go through exactly the same thing a few seasons later.
