Other coastal places get battered in summer and recover through winter. This stretch does not really let up, and the practical consequence is that mechanical wear here accumulates without a break. Doors get shoved and hauled at without pause, closers labour well beyond their rating, hinges carry load in a single direction all year, and a bolt loses its line on the keeper years earlier than the same door would inland.
Layered onto that is salt, and layered onto that is sand. Corrosion eats a mechanism from the inside while abrasion grinds it from the outside and the wind supplies both. It is about as unforgiving a combination as hardware faces, and it is why almost every recommendation we make in this town starts from durability rather than from resistance.
The town's own economy is the second factor. There is a genuine village centre here with shops, restaurants and services that trade to a permanent population rather than only to visitors, which means business lockout work is a real part of what we do rather than an afterthought. Those premises face exactly the same weather as the houses, and their doors are opened many times more often.
