FAQs
Window Lock Mechanisms in Northolt — Your Questions
Can you replace the lock without replacing the window?
Yes — in almost every case we replace just the mechanism or gearbox, not the window.
What is an espagnolette?
It’s the long locking bar running inside your window frame, driven by the handle. When it wears or snaps, the window stops locking — and it’s a straightforward replacement.
Do you fit higher-security locks?
Yes — we can upgrade window locks to higher-security options for extra peace of mind.
Can you help after a break-in?
Yes — we repair and upgrade damaged locks promptly to make your property secure again.
Will you have the right part?
We carry the common mechanisms. For anything unusual we measure and order it, usually returning within a few days.
