Lock Installation in Earlsfield
A lock is only as good as its installation. A top-of-the-range cylinder fitted at the wrong depth, with poor alignment and incorrect fixings, will fail sooner than a mid-range lock fitted properly by someone who knows what they are doing. We install locks correctly the first time, on the right doors, with the right hardware for how your property is actually used.
Whether you need a single lock fitted on a new front door or a full set of locks across an entire property, we take the same approach: check the door, check the frame, understand how the entrance is used, and fit something appropriate.
When you need a new lock fitted
There are dozens of reasons to fit a new lock. The most common ones we see in Earlsfield are:
● Moving into a new property. You have no idea who has copies of the old keys, and a lock change is the simplest way to start fresh
● Upgrading after a break-in or attempted break-in, where the old lock was clearly not up to the job
● Replacing a lock that has worn out, seized, or started to malfunction
● Adding a lock to a door that never had one, such as a side gate, garage, internal office or storage room
● Meeting insurance requirements, which typically means fitting a BS3621 mortice deadlock
● Fitting a new back door, side entrance, or French door lock
● Switching to a more convenient setup like thumbturn cylinders, keypad locks, or a keyed-alike system where one key opens all your doors
What we install
We fit a wide range of lock types and brands:
● British Standard BS3621 mortice deadlocks and sashlocks
● Night latches (Yale-type rim locks)
● Euro cylinders, including anti-snap and high-security options
● Multipoint lock components for UPVC and composite doors
● Window locks, restrictors and espagnolette handles
● Internal privacy locks, bathroom locks and bedroom locks
● Gate, garage and side access locks
● Digital and mechanical keypad locks where keyless access is preferred
Rather than fitting the same lock on every door, we consider what the door is made of, how often it is used, who needs access, and whether there are insurance or landlord requirements to meet. A solid Victorian front door needs a different setup to a hollow-core internal door in a new-build flat, and we make sure the hardware matches the situation.
Carried out in one visit
We carry a good range of locks, cylinders and hardware in the van, so most installations are completed on the same visit. If you need something specialist or unusual that we do not have in stock, we can usually source it within a day or two and return to fit it at a time that suits you.
