Are your uPVC casement open-out windows not closing properly, letting in draughts, catching on the frame or leaving a visible gap around the opening when shut? Worn, damaged or failed window hinges are a common cause.
If your uPVC window has developed a gap, feels draughty, catches against the frame or needs to be pushed or lifted before the handle will lock, the problem may be with the window hinges rather than the complete window. Most opening uPVC casement windows use metal friction-stay hinges to support and guide the opening sash. Over time these hinges can wear, become distorted, corrode or lose their original alignment. When that happens, the opening sash may no longer pull evenly back into the frame. Where the window frame and sash are otherwise serviceable, replacing the worn hinges can often restore normal operation without the cost and disruption of replacing the complete window.

Window hinges work every time you open and close your casement open-out window. They support the weight of the opening sash while guiding it away from the frame and then pulling it back into position when the window is closed. After years of use, the moving parts can wear and the hinge may no longer guide the sash into its original position.
Problems can also develop because of corrosion, repeated force, excessive sash weight, previous incorrect adjustment, damaged fixings or general wear and tear.
Once the hinge geometry changes, even slightly, the sash may stop sitting evenly against the frame.
The result can be draughts, gaps around the sash, difficulty locking, the window catching, reduced compression against the seals, excessive movement, a window that no longer closes correctly
Replacing the worn hinge set can often restore the sash to a much better closing position.

When a uPVC casement window starts draughting, dropping or catching on the frame, you shouldn’t automatically need new windows. Window Fixers specialises in replacing worn and failed friction-stay hinges across London, keeping your existing frames and glass wherever possible. From standard side-hung and top-hung casements to restrictor, egress and easy-clean hinges, we provide clear pricing, correctly matched replacement hinge sets and a 1-year parts and workmanship guarantee, so you get a lasting repair without paying for unnecessary window replacement.
A draughty, dropped or badly closing sash rarely means a new window. We replace the worn friction-stay hinges while keeping your existing frame and glass.
Every hinge replacement is backed by a 1-year guarantee covering both the replacement parts and our workmanship.
Send us a photo of your window for an initial quote. Clear pricing from £175 per window, no call-out charge and no hidden extras.

Free assessment & fixed quote
Email or WhatsApp us a photo or video of the window — ideally the full window plus a close-up of the hinge and any gap. We’ll identify the hinge type and size you need, whether it’s a standard friction stay or a restrictor, egress or easy-clean hinge, and send you a fixed quote. No call-out charge.
Fitted and adjusted, usually same day
Our technician takes out the sash, removes the worn or warped friction stays and fits a new matched pair. The sash is then realigned in the frame and the handle and locking points checked so the window closes and seals correctly.
No mess. No damage to your frames or glass.
Guaranteed for 12 months
Before we leave, we open and close the window with you and check it locks without lifting or forcing. The sash sits square, the seals compress properly and the draught is gone. Parts and workmanship are guaranteed for 1 year, and you pay only once the repair is complete.

Common signs include a visible gap around the opening sash, draughts near the hinge side, the sash dropping or catching, difficulty closing the window and having to push or lift the sash before the handle will lock.
These symptoms can also have other causes, so the window should be assessed before parts are replaced.
Worn or damaged hinges can allow the opening sash to sit out of position, leaving a gap between the sash and frame.
The problem may be particularly noticeable toward one corner or along the hinge side.
Yes. If worn hinges prevent the sash from closing tightly against the frame, air can pass through the resulting gap.
However, draughts can also be caused by other issues, so we diagnose the window before recommending a repair.
Usually not if the frame and sash are otherwise serviceable.
In many cases the existing hinges can be removed and replaced while keeping the original window.
Friction stays are the metal hinge mechanisms commonly fitted to outward-opening uPVC casement windows.
They support the sash and control its movement as the window opens and closes.
Window hinges work together as a matched pair to support, guide and correctly position the opening sash. If one hinge has worn or failed, the other hinge will usually have experienced the same age, use and load. For this reason, we replace both hinges together to restore balanced operation and help the window open, close and sit correctly within the frame.
Wear in the hinges, damaged components, movement or other alignment issues can cause an opening sash to sit lower or differently in the frame.
An assessment is needed to establish the exact cause.
If the sash is no longer being held in its correct position, it may rub or catch against the surrounding frame as you close it.
Worn hinges are one possible cause.
Many first-floor uPVC casement window repairs can be completed from inside the property, depending on the design of the window and safe access requirements.
We’ll assess accessibility before confirming the work.
Our specialist repair service is focused primarily on suitable uPVC window systems. Send us photos of your window if you’re unsure whether it is something we cover.
If the opening sash is out of alignment, the locking points may no longer line up correctly with the keeps in the frame. The fault could relate to the hinges, lock mechanism, keeps or a combination of components.
Needing to lift or reposition the sash before the handle operates suggests that the sash is not sitting correctly in the frame. Worn hinges are a common possible cause and should be inspected.
That depends on their condition and the cause of the fault. Where a hinge is simply worn, bent, damaged or no longer operating correctly, replacement may provide a more appropriate long-term repair than attempting to compensate for a failed component.
Yes, we repair suitable side-hung and top-hung uPVC casement windows that open outwards.
Specialist egress or fire-escape hinges need to be identified and matched appropriately. We assess the existing configuration before confirming the repair.
Yes, where a window uses a restricted-opening or specialist hinge arrangement, we’ll first identify the existing setup and determine the appropriate replacement.
Where corrosion has damaged the friction stays and the surrounding sash and frame remain suitable, the hinges can often be replaced.
We also check the surrounding area for issues that may have contributed to the deterioration.
The time required depends on the window size, accessibility, sash weight, hinge configuration and condition of the existing components.
We’ll advise you once we’ve assessed the window.
The easiest way is to send us photographs or a short video by WhatsApp.
Please include a photograph of the complete window and, if possible, show the gap, damaged hinge or difficulty you experience when closing it.
We’ll assess the likely fault and provide an initial quotation or advise what additional information is required.
Our standard uPVC casement window hinge replacement costs £175 per window for most small to medium-sized double glazed, outward-opening windows. This covers both top-hung and side-hung casement windows using standard friction-stay hinges from 8 to 16 inches.
For larger windows requiring 20-inch or 24-inch hinges, the cost is £195 per window.
If you have three or more windows requiring hinge replacement at the same property, you’ll receive a 20% multi-window discount on the hinge replacement price.
Some windows require specialist hinges depending on their size, weight or opening requirements:
Restrictor hinges: +£15 per window
Egress / fire escape hinges: +£15 per window
Easy-clean hinges: +£15 per window
Heavy-duty hinges for heavier windows: +£35 per window
These prices apply to standard, safely accessible uPVC casement windows. Very large or unusually heavy windows, externally glazed windows, difficult-access locations, or installations requiring specialist equipment or additional work may require a bespoke quotation.
Send us a few photos or a short video of your window and we’ll confirm the most suitable hinge type and provide a clear quotation before the work is booked.
