Not every stiff lock needs replacing. Sometimes the problem is a door that has dropped two millimetres, a strike plate that has shifted, or a mechanism that just needs cleaning and lubricating after years of daily use. We see this constantly in Earlsfield, particularly on the older terraced houses where timber doors swell and shrink with the seasons, gradually pulling the lock out of alignment with the frame.

Before we touch anything, we check the lock, the door and the frame together. There is no point fitting a new cylinder if the real problem is that the door has dropped and the bolt is catching the strike plate at the wrong angle. Getting the diagnosis right saves you money and means the fix actually lasts, rather than masking the problem for a few weeks until it comes back worse.


Signs your lock needs attention

Locks rarely fail without warning. There are usually signs in the weeks or months beforehand, and catching them early is always cheaper and less stressful than dealing with a complete failure. Look out for:

       The key is getting harder to turn each week

       You have to lift the handle and push the door at the same time to get it to lock

       The latch does not click shut on its own when you close the door

       The deadbolt scrapes, sticks, or only extends partway

       The handle feels loose, wobbly or disconnected from the mechanism

       You can hear grinding or scraping when you turn the key

       The door only locks if you push it hard into the frame first

Any of these symptoms means the lock, the door or the frame needs some attention. Ignore them and you will eventually find yourself locked out, locked in, or unable to secure the property at all. A ten-minute adjustment now can prevent a much more expensive emergency later.


What we adjust and repair

We work on all common residential and commercial lock types:

       Mortice locks, including sash locks and deadlocks

       Night latches (Yale-type locks)

       Euro cylinders

       Multipoint locking mechanisms

       Window locks and espagnolette handles

       Internal privacy and bathroom locks

       British Standard deadlocks


The adjustment might be as simple as repositioning the strike plate, tightening the fixing screws, lubricating the mechanism, or shaving a millimetre off the door edge where it has swollen. In other cases the lock needs a new part, a new spindle, or a replacement keeper. We carry common parts and spares in the van, so most adjustments and repairs are completed in a single visit without needing to order anything in.


When repair is not enough

If the lock is too worn, corroded, or mechanically damaged to repair reliably, we will tell you straight. There is no point adjusting a lock that is going to fail again in a month. In those cases we will recommend a replacement and explain why, so you can make an informed decision rather than just taking our word for it.
