Common uPVC window lock problems
Sash and casement windows in Hampstead's Victorian and Edwardian houses lose their catches over time, and uPVC windows in newer blocks around Colindale and Kilburn wear differently.
A handle that turns but does not lock, a handle that has snapped, or a window that will not close tight. Most of these come from a worn handle or a failed espagnolette, the locking bar inside the frame.
We replace handles with locking handles where you want them, so windows can be locked with a key, and fix or replace the mechanism behind them. Patio and French door locks are part of the same job.

Window lock repair in Northwest London: common questions
How much is a window lock repair in Northwest London?
From £69 for a uPVC window handle or lock. If the locking mechanism inside the frame has failed, the engineer tells you the price for that before doing it.
Can you fit locking window handles?
Yes. We fit keyed locking handles to uPVC windows, often asked for by insurers and by parents of young children.
How do I pay?
When the job is finished. Card, cash or bank transfer, and you get a written receipt you can use for an insurance claim.
My window will not close properly. Can you fix it?
Usually, yes. It is often the hinges or the keeps that need adjusting, which is quicker and cheaper than replacing parts.
How quickly can someone get to me?
An engineer is typically with you in 15 to 20 minutes, and within 30 minutes at most. We give you a time on the phone based on where the nearest engineer is right now.
Do nights and weekends cost more?
No. The price is the same at 3am on a Sunday as it is at midday on a Tuesday, bank holidays included.
Do you cover Hampstead, Golders Green, Hendon and Mill Hill as well as Camden?
Yes. The same 24-hour line covers the NW postcode area, including Camden, Primrose Hill, Hampstead, St John's Wood, Kilburn, Cricklewood, Willesden, Hendon, Golders Green and Mill Hill.
Can an older timber front door in Hampstead or St John's Wood be fitted with a modern BS3621 lock?
Usually yes, if the door itself is sound. The engineer looks at the door, says which lock suits it and confirms the price before any work begins.
