Vintage Mortise Lock Service in Tottenham

The key turns freely in the round cylinder on the door, all the way around and back, without the bolt shifting at all. The cylinder itself wobbles slightly when you press it, as if it has come loose inside the door.

In plain words

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.

Sound familiar?

The brass knob on the front door of your century home turns, but nothing happens on the other side. The latch stays tucked in, the door swings free, and the only thing holding it shut is the deadbolt and a bit key that has worn down to a nub.

  1. 1

    How the knob and key actually behave

    A short conversation with the hardware comes next. The knob is turned and released: does it return smartly, sag back, or not return at all? Is there free play before the latch moves? The key is tried in the deadbolt with the door open: does the bolt throw fully, catch part way, or ignore the key while the key turns? The thumb-turn gets the same test. Each answer points somewhere different inside the case, a latch spring, a hub spring, a worn hub square, a deadbolt lever, a cylinder cam, and the locksmith is building a short list of likely parts before the cover ever comes off.

  2. 2

    Putting the door edge right

    Before the case goes back, the pocket and screw holes get whatever attention the check turned up. Stripped holes are drilled out, plugged with glued hardwood dowel and re-drilled so the faceplate screws bite. A pocket that has loosened is packed with a thin hardwood shim glued to one wall so the case sits tight. A split at the edge is glued and clamped. None of this changes the door's appearance; it simply gives the rebuilt lock something solid to sit in, which matters because a case that shifts in its pocket will bind the spindle and undo the bench work in a few months.

  3. 3

    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

  1. 1

    Bit key or cylinder lock

    A bit-key case has keys filed by hand on the bench, while a cylinder lock is rekeyed or fitted with a new cylinder on a key machine. The two take different time and materials, and the quote follows.

  2. 2

    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.

  3. 3

    Paint and seized parts

    Hardware buried under decades of paint takes time to free and clean without damage. A faceplate, strike and thumb-turn that have to be stripped back add to the visit and are noted in the quote.

Same fees day, night or weekend.

Vintage Mortise Lock Service: questions

Advice · (249) 501-0299

How long does servicing a mortise lock take?

A single entry lock that needs cleaning, springs and a strike adjustment is generally done in one visit of an hour or two. Filing a bit key adds bench time, and a set of interior latches is longer simply because there are more of them. A case that needs a part fabricated, or a replacement case that has to be ordered to size, may mean a second visit; the locksmith says so at the assessment.

What does the service visit involve, step by step?

The locksmith checks your authority to request the work, examines the door and lock, and tells you what it needs. The knobs, plates and cylinder come off, the case slides out of the door edge and is opened on a bench, cleaned, re-sprung and repaired. Keys are made or the cylinder rekeyed, the door pocket is tidied, everything goes back on, and the strike is adjusted. You test the finished lock from both sides.

Can a modern cylinder be fitted to my old mortise lock?

Often, on cases that already take a threaded cylinder. Mortise cylinders are made in standard thread sizes and lengths with different cam shapes, and a new one is selected to match the case and the door thickness. That gives you keys cut on a machine and the option of keying the door alike with the rest of the house. A bit-key case has no cylinder to swap; its keys are made on the bench instead.

What the census means at the door

32%

Newer homes. About 32% of homes in New Tecumseth were built in 1980 or earlier, according to the 2021 Census.

Where housing is new, garage entries, side doors and the front door were usually fitted at the same time but not always to the same key. Keying them alike is a small job that makes the household's ring simpler from the start.

71%

Mostly houses. Single-detached houses make up about 71% of homes in New Tecumseth (2021 Census).

Where homes are mostly detached, patio and sliding doors deserve attention alongside the hinged ones. Auxiliary locks, pin locks and better latches for sliders are routine additions that a locksmith brings on the same visit as the front door work.
