Vintage Mortise Lock Service in Greens Corners
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.
Vintage Mortise Lock Service
In plain words
The trim on the door face is the other half of the lock. The knobs ride on a square spindle that passes through the hub of the case, held by small set screws, and the escutcheons cover the spindle and keyholes. Slack in a knob, a knob that pulls off in your hand, or a thumb-turn that spins without moving the bolt usually traces to a worn spindle, a stripped set screw or a hub whose square has rounded. The service replaces spindle and screws, matches a hub or lever from stock or makes one, and fits everything so there is no free play before the latch starts to move.
How the visit goesThe knob flops loose on its spindle and never springs back to level. When you turn it the latch pulls in, but you have to push the knob back yourself, and lately the latch has started staying inside the door instead of catching.

How the visit goes
Reading the faceplate
Standing at the open door, the locksmith looks at the narrow brass or steel plate in the door edge. Its height, the spacing of its screws, any maker's stamp, and whether it shows one bolt or two tell a good deal about what is inside: a latch-only case for an interior door, a latch and deadbolt case for an entry, or a privacy function with a turn button. The distance from the door edge to the centre of the knob, the backset, is measured, along with the spindle size. These figures decide which springs, followers and, if it comes to that, which replacement case will fit, so they are written down before the lock is disturbed.
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.
The interior doors in step
Where a set of interior mortise latches was serviced together, you leave with bedroom and bathroom doors that close and stay closed, privacy turns that actually lock, and, if you wanted it, a single bit key that operates every interior lock the way the builder intended. A note of which key fits which door goes into the house file. Interior cases need almost no care beyond a drop of oil every couple of years and a check that a turn button has not been painted over. A child who locks a bathroom and cannot reopen it is released from outside with the bit key, so keep it somewhere the adults can reach.

What affects the quote
Same fees day, night or weekend
1Extras 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.
2Whether the door has to come off its hinges
Some mortise cases can be serviced with the door hanging in place, while a tight jamb or a stubborn case sometimes means lifting the door off its hinges onto a level bench. That step is identified once the case is open and the repair needs are clear.
3Bit 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.
Vintage Mortise Lock Service: questions
Which parts usually need replacing?
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.
Will the door look any different afterwards?
Usually not, when the original case is repaired: the same knobs, escutcheons, faceplate and strike go back on in the same positions, and the only visible change is paint or grime cleared from the edges that were catching. A replacement case is chosen to match the pocket so original trim is reused wherever spacing allows, though an occasional case needs a small pocket or fixing change, explained beforehand.
What exactly is a mortise lock?
It is a lock built as a flat rectangular case that sits inside a pocket cut into the edge of the door, rather than through a round hole bored across it. The case holds the latch, usually a deadbolt, the hub the knob spindle turns, and the springs. On the faces of the door you see the knobs, decorative plates and either a keyhole for a bit key or a round cylinder. Most doors built before the middle of the last century carry one.
