Vintage Mortise Lock Service: questions about the price

Springs, first and foremost: the latch spring, the hub spring that returns the knob, and the small springs on the deadbolt levers. After that, the spindle and knob set screws, a hub whose square has worn round, a worn deadbolt lever or follower, and on later locks the cylinder set screw or the cylinder itself. Bolts, cases and trim are almost always kept, cleaned and refitted rather than replaced.

Missing or mismatched trim

Sourcing a knob, escutcheon or thumb-turn to match the survivors, from salvage or reproduction stock, is quoted as parts plus the search. Reusing your own trim from another door avoids that line.

Extras you choose on the day

A high-security cylinder, a lockbox for a spare bit key or a separate modern deadbolt above the original are optional additions. None is required to make the old lock work, and each is priced as its own line.

Travel and access

Distance to the property and how easy it is to work at the door, on a busy entry or a third-floor walk-up, are part of any call-out and are stated when the visit is booked.
