Vintage Mortise Lock Service in Woolwich
Someone painted the door years ago without removing the hardware.
In plain words
Most old mortise locks fail for boring reasons. A coil spring that has been compressed a hundred thousand times since the house was built finally breaks, or the grease inside the case dries into something like wax and the levers stick in it. Neither justifies cutting a new hole in a solid oak door. The service opens the case, cleans out the old lubricant, replaces the springs with the right size, matches any worn follower or lever and lubricates the mechanism lightly. The same case goes back into the same pocket, and the knob returns to level with the crisp snap it had decades ago.
How the visit goesThe old skeleton key still fits the keyhole, but it now needs a jiggle, a lean on the door and a little luck before the bolt moves. Last week it took three tries. You have one key and no idea where a second could come from.

How the visit goes


The door before the lock
Before blaming a lock that may be perfectly sound, the locksmith looks at the door. With it open, the lock is cycled; with it closed, the latch and deadbolt are tried again. A lock that works open and fights when shut is telling you the door has moved. The gap around the door is checked top to bottom, the hinges are watched for a sag when the door is lifted, and the strike plate is inspected for bright wear marks where the bolt has been scraping past. In an older home with a solid wood door this is a routine finding, and correcting it is often most of the repair.
Inside the case on the bench
With the cover screws out, the case opens like a book: the latch bolt with its spring, the hub the spindle passes through, the deadbolt with its lever or tumblers, and the springs holding each in place. The locksmith notes what is broken, worn or merely stuck, then cleans the case with solvent and a brass brush until the old grease and rust are gone; old paint on the hardware is treated as a possible lead hazard and cleared with contained, lead-safe methods rather than dry brushing. Parts are cleaned individually, burrs are dressed off the bolts, and the hub square is checked against a fresh spindle to see whether it has rounded.
A clear way out
If the entry door's deadbolt was keyed from both sides, the service leaves the inside operable without a key: a thumb-turn fitted to the bolt tail, or a knob function that releases the latch from inside. This is simply good sense for a door people use to leave the home, so nobody is stuck hunting for a key inside their own house. You are shown how the inside release works and asked to try it, and everyone in the household should know it too, especially anyone who grew up with the old habit of leaving the key in the door on the inside.

What affects the quote
Making the inside key-free
Fitting a thumb-turn or interior release to a deadbolt that was keyed on both sides is its own small item, and one most owners of an entry door choose to include.
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.
Parts that must be ordered
A reproduction case or an unusual cylinder size may have to be ordered to measurement, which means a second visit to fit it. The quote separates the first visit from the return.
What to have ready
- Do you own the home or rent it, and who should receive the keys?
- How many doors need attention, and are any of them interior doors?
- Is the property designated as a heritage building?
Vintage Mortise Lock Service: questions
QuestionsWhy does the deadbolt scrape or need a shove to throw?
Two causes cover most cases. Either paint has built up on the faceplate, the bolt or the strike so the bolt drags across it, or the door has dropped so the bolt is entering the strike pocket at an angle and rubbing its edge. Occasionally a bent deadbolt lever inside the case adds friction. Cleaning the paint back, adjusting the strike and checking the lever all happen as part of the service.
The lock works with the door open but not when it is closed. Is the lock broken?
Almost certainly not. That pattern means the door has moved in its frame so the latch and bolt no longer meet the strike squarely. Solid wood doors in older houses swell in humid weather and settle on their hinges over the years. The service adjusts or shims the strike and tightens or packs the hinges so the bolt throws without lifting the door, and the lock itself is usually cleaned and lubricated at the same time.
Can you match a missing knob, plate or thumb-turn?
Often, yes. Locksmiths who work on older hardware keep salvage and reproduction trim in the common patterns and finishes, and a knob, rosette or escutcheon can usually be found close enough that the pair on one door match. Where nothing suitable exists, the trim from a less visible door can be moved to the entry and the reproduction fitted where it is seen less. Bring or photograph the surviving piece so it can be matched.
