For double glazing repair in West Derby we focus on the parts that wear out: door gearboxes and multipoint locks, floppy handles, window handles and espagnolette gears, friction stay hinges and seals, as well as misted or broken glass units. Much of West Derby (L12, with parts of L13 and L14) is inter-war and post-war semis and terraces, and many have uPVC hardware that has now done decades of daily use.
When a door handle goes floppy
This is one of the most common calls we take from West Derby. The handle drops, feels loose, or will not lift to engage the lock. The cause is usually inside the door rather than the handle:
- Gearbox spring broken – the gearbox is the central part of the multipoint lock behind the handle; when its spring fails the handle loses its return.
- Worn gearbox – years of lifting and slamming wear the internal parts; the key may also become hard to turn.
- Handle spring cassette – some handles have their own springs, and replacing the handle alone fixes it.
We identify which it is before ordering anything. If the door has also dropped, we adjust it so the new gearbox is not strained from the first day. Our uPVC door repair page explains alignment problems in more depth.
Window handles, gears and hinges
On the window side, the handle drives an espagnolette (shootbolt) gear running round the sash. When that gear wears, the handle may spin, jam halfway or turn without opening the window. Sometimes only the handle is cracked or its spindle has sheared, and a replacement window handle is all that is needed. Where the sash has sagged on its friction stays, it can bind on the frame and strain the gear, so we check the hinges at the same time.
If a window will not open, do not lever the sash with a tool. You can bend the hinges or crack the frame. On an upstairs bedroom window that is an escape route, ask us to look at it promptly.
Glass and seals on older windows
Hardware is not the only thing that ages. First-generation sealed units can mist between the panes as their edge seals fail, and older wedge gaskets shrink back from the glass. We replace failed units with new ones made to measure, and fit new gaskets and sash seals where draughts or rain are getting in. If the units are clear but you want warmer rooms, modern low-E glass is an option worth asking about.
Parts for ageing doors and windows
Owners sometimes worry that their windows are too old to find parts for. In practice, much uPVC hardware follows common sizes, and where an original part is no longer made we can often fit a compatible one. At the visit we measure backsets, centres and lengths and may photograph markings on the lock edge. Small parts can often be fitted that day if we carry them; others are ordered and fitted on a short return visit.
Security while we are there
If your door still has its original euro cylinder, it is worth checking it for a TS 007 Kitemark with three stars, or a Sold Secure Diamond mark. Without either, ask about an anti-snap lock upgrade, fitted at the correct length so it does not sit proud of the handle.

Frequently asked questions
Why has my uPVC door handle gone floppy?
A handle that droops or no longer springs back is often a broken spring in the gearbox or a worn gearbox, and sometimes a broken spring cassette in the handle itself. We check which it is before ordering parts, so you are not paying for a new handle when the fault is inside the door.
Can you get parts for old uPVC windows and doors?
Usually. Many locks, gearboxes and hinges follow common sizes, and where an exact part is no longer made a compatible one can often be fitted. We measure the backset, centres and lengths at the visit so the replacement suits your door or window.
Do you cover L13 and L14 as well as L12?
Yes. West Derby is mainly L12, with parts in L13 and L14, and we cover all of them along with neighbouring Norris Green, Walton and Huyton. Give us your postcode when you call.
My window handle turns but the window will not open. Is that dangerous?
It is not dangerous in itself, but do not force it. Usually the espagnolette gear inside the sash has failed and is not moving the locking points. If it is a bedroom window needed for escape, treat it as a priority and call us.
