When your guardian doors and windows start to play up — stiff to open, hard to lock, letting in draughts, or showing misted glass — the knee-jerk reaction is often to replace them. In the vast majority of cases, that's unnecessary. UPVC frames are built to last 20–35 years. What fails first is the hardware: hinges, handles, locking gearboxes, friction stays, rubber seals, and sealed glass units. All of these are replaceable parts — and replacing them costs a fraction of a new window or door.
The Glass Guardian specialises in exactly this. We're a Birmingham-based UPVC repair service covering the full Black Country area — Dudley, Walsall, Wolverhampton, West Bromwich, Sandwell, Halesowen, and beyond. Our technicians carry an extensive stock of parts so most guardian doors and windows faults are resolved on the first visit, without the need to wait for parts or book a second appointment.
UPVC Window Repairs
Window faults range from minor inconveniences to genuine security risks. A window that won't latch properly or a broken friction stay that stops the window staying open are both worth addressing quickly. Common window repairs we carry out include:
- Broken or stiff window handles
- Worn or seized window hinges and friction stays
- Failed espagnolette mechanisms
- Misted or condensation-filled sealed units
- Cracked or broken glass replacement
- Draught and weatherseal replacement
- Windows that won't lock, or won't stay open
Most window repairs take 30 minutes to two hours. For misted double glazing we measure the sealed unit on the first visit, order it, and return to fit it — usually within a few days. Read more about our UPVC window repairs service.
UPVC Door Repairs
Guardian doors and windows issues are often most noticeable with doors — a front door that has to be lifted to lock, a back door letting in cold air, or a multipoint lock that's jammed. These are all repairable faults. We work on all types of UPVC and composite doors:
- Multipoint lock gearbox replacement
- Door cylinder (barrel) replacement
- Dropped door adjustment and realignment
- Door handle replacement — lever-lever and lever-pad
- Draught seal and weather strip replacement
- UPVC and composite door panel repairs
- French door and patio door mechanism repair
Having to lift the handle to lock the door is the most common fault we see — it means the gearbox is worn and the door latch is no longer engaging cleanly. It's a straightforward fix. Read more about our UPVC door repairs service.

Frequently Asked Questions
What types of guardian doors and windows do you repair?
We repair all types of UPVC windows and doors, including casement windows, tilt-and-turn windows, sliding sash windows, front doors, back doors, French doors, and patio doors. We also repair composite doors with the same multipoint locking hardware.
How much does it cost to repair a guardian door or window?
Most UPVC window repairs cost between £60 and £150 depending on the fault and parts needed. Door repairs, particularly multipoint lock gearbox replacements, typically cost between £80 and £200. We provide a free, no-obligation quote before any work begins — no hidden charges.
Can you fix a door or window the same day?
In many cases yes. We carry a wide range of the most common UPVC door and window parts — handles, gearboxes, hinges, cylinders, friction stays, and seals — so most repairs are completed on the first visit. For less common parts we order and return quickly, usually within a few days.
Is it worth repairing rather than replacing my windows or doors?
Almost always, yes. UPVC frames are built to last 20–35 years — it's the hardware (handles, hinges, locks, sealed units) that wears out first. Replacing just the faulty component costs a fraction of a full window or door replacement and leaves you with the same result: a secure, draught-free home.
