Fresh Lock Installation in Harrow
New door, a second lock for extra security, or a lock where there wasn’t one before? I fit fresh locks properly and to standard across Harrow and the surrounding areas – measured, aligned and warranty-backed. Lock installation from £89 labour, no call-out fee.
Getting a lock installation right matters – the wrong lock, or one fitted badly, is a weak point a burglar will find. I fit quality locks, aligned properly, so they work first time and keep working.

What I install
- New cylinder and mortice locks
- Second / additional locks and deadbolts
- Nightlatches (Yale-type)
- Locks on new or replacement doors
- Insurance-specified locks
Mortice lock fitting & British Standard locks
Mortice lock fitting: wooden doors take a mortice lock cut into the door edge. I fit and upgrade BS3621 British Standard mortice locks – the standard most home insurers ask for on a final-exit door. If your timber door has only a nightlatch and no mortice deadlock, it’s likely below what your policy expects; I can put that right. I fit British Standard cylinders and nightlatches too, from leading manufacturers, and suggest the right lock for your door and budget.
