Vintage Mortise Lock Service
The interior bedroom doors on the second floor have the original mortise latches, and none of them close any more. The doors drift open, the small brass turn buttons do nothing, and the keyholes have been empty for as long as anyone can remember.

Where the door has moved, the lock gets blamed. Solid wood doors in older houses swell in humid weather, shrink in winter and settle on their hinges, and a mortise lock that was set decades ago ends up with its latch and bolt aiming a little below the strike. Part of every vintage lock service is reading how the door hangs, tightening or packing the hinges, and moving or filing the strike so the latch catches and the bolt throws without lifting the handle. Often that alignment work, plus a clean and new springs, is the entire repair, and the customer gets back a door that closes with one hand.
How the visit goesAfter a wet summer the entry door sits lower in its frame. The lock works perfectly when the door is open, but with it shut you have to lift the handle and shoulder the door to get the deadbolt to throw.

How the visit goes

- 1
Who owns the door
The first check has nothing to do with the lock. The locksmith confirms that the person asking for the work owns the home or lawfully lives in it, since a serviced lock and a freshly cut key are, in the end, a way into someone's house. Photo identification and something tying you to the address usually settles it in a moment. On a rental, the landlord and the tenant are expected to agree on lock changes and share keys, so the locksmith asks who should hold the new bit keys or cylinder keys and notes it. This small formality protects the household as much as anyone, and it is done before a screwdriver comes out.

Taking the lock out without marking the door
Removal is done in a set order so nothing is forced. The knob set screws are backed off and the knobs and spindle drawn out, then the escutcheons are lifted away, their screw positions photographed for reassembly. On a cylinder lock, the small set screw in the faceplate is released and the cylinder is unthreaded from the case. The faceplate screws come out, and the case is eased from its pocket with a gentle rock, never a pry bar, because the wood at the edge of an old door is thin. Everything that comes off is bagged and labelled, and the pocket is looked at while it is empty.

Watching the door through the seasons
The lock is aligned to the door as it hangs today, and a solid wood door in an older home will move again. Through a humid summer it swells, through the heating season it shrinks, and each year the hinges settle a fraction. Twice a year, close the door and try the latch and bolt; if either has started to scrape or needs the door lifted, the strike wants a small adjustment or the hinge screws want snugging, which is a five-minute job. Doing that early keeps the rebuilt case from being strained, and it is the single habit that makes a vintage lock last another few decades without fuss.

What affects the quote
- 1
Condition of the wood
Stripped screw holes, a loosened pocket or a split at the door edge need dowelling, shimming or gluing before the case can be trusted. That woodwork is quoted once the locksmith has seen the pocket empty.

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.

Strike and hinge work
Where the door has dropped or swelled, adjusting or moving the strike and tightening or packing hinges is part of the fix. It is small work but it is listed, so you see what was done to the door.
Same fees day, night or weekend.
Vintage Mortise Lock Service: questions
How should I look after the lock once it is serviced?
A drop of the right lock oil into the latch and bolt once a year is plenty. If the lock has a pin-tumbler cylinder, use whatever lubricant that cylinder's maker specifies, since some take a dry graphite or PTFE product and others a specified liquid one. Try the latch and deadbolt each spring and fall; if the bolt starts to scrape, the strike wants a small adjustment before anything is strained. Keep bit keys out of a pocket where they bend.
Do I need to prove I own the house before you work on the lock?
Yes, and it is a normal part of any lock or key work. Photo identification together with something that ties you to the address is enough. If you rent, the locksmith will ask who should receive the keys, because landlords and tenants in this province are expected to agree on lock changes and share keys. This check takes a moment and it protects every household the locksmith is asked to work for.
My home is a designated heritage property. Does that change anything?
It reinforces the choice to service rather than replace. Where a property carries a heritage designation, changes affecting listed features can need extra sign-off, and original door hardware is occasionally among those features. A rebuilt mortise case with its original trim is preservation rather than alteration, and the locksmith's written record of what was retained and what was replaced is useful for your file.

What the census means at the door
25%
Newer homes. About 25% of homes in Whitby were built in 1980 or earlier, according to the 2021 Census.
Recent builds often have steel or fibreglass entry doors rather than solid wood. They resist warping and take hardware well, and a locksmith fitting a deadbolt or reinforced strike works with the door's construction so screws bite into something solid.
70%
Mostly houses. Single-detached houses make up about 70% of homes in Whitby (2021 Census).
A detached house gives a locksmith room to work: full access to both sides of every door, hinges and frames included. Repairs and upgrades can be thorough, from the front deadbolt to the gate latch, with nothing off limits.
