01The problem
A door that will not latch is usually a door that has dropped. Hinge screws strip out into soft framing, the door sags a few millimetres, and the latch stops meeting the strike plate. A new lock does not fix any of that, because the lock was working fine.
02What we did
We replace failed hinges, drive into solid material instead of a stripped hole, realign or shim the strike plate, and adjust the door so it closes with a push instead of a shoulder. Where a keypad deadbolt is going in, we check the door thickness and backset first, then set the codes with the homeowner before we leave.
03The result
Doors that latch on the first try. This is the cheapest repair we do and the one people put off longest.
