uPVC Window Hinge Repair in Liverpool

What are friction stay hinges?

A friction stay is a hinge and a stay in one. Instead of a pin hinge on one edge, the sash is carried on two arms that slide in a track, with a friction shoe that holds the window at whatever angle you leave it. They come in different lengths, weight ratings and types:

• Standard side-hungFor windows that open like a door. The sash swings out from one side.
• Top-hungFor fanlights and top openers that swing out from the top.
• Easy-cleanMove the sash across as it opens, leaving a gap at the hinge side so you can reach the outside of the glass from indoors.
• Egress (fire escape)Open the window wide with a clear gap at the hinge side, so the opening can be used to escape in an emergency.
• RestrictedLimit how far the sash opens at first, with a release for full opening.

Getting the type right matters as much as the size. Swapping an egress hinge for a standard one, for example, can leave a much smaller clear opening.

Signs your window hinges need replacing

• The sash has dropped and the bottom corner catches on the frame as you close it.
• You have to lift or push the window to get the handle to lock.
• The window will not stay open and swings in the wind, or is very stiff to open.
• The hinge arms are visibly bent, rusted or have come away from the frame.
• There is a gap or a draught at the top or hinge side when the window is shut.
• Grinding or crunching as the window opens.

Hinge and lock faults often go together. A dropped sash forces the lock cams against the keeps, which can wear or break the espagnolette. If your window is also hard to lock, our uPVC window lock repair page explains what to look for.

Why do uPVC window hinges wear out?

Friction stays carry the full weight of the sash and glass every time the window moves. Over years the friction shoes wear, the rivets loosen and the arms flex. Large, heavy sashes wear their hinges faster, especially if the hinge was undersized to begin with. In windy, exposed spots, a window left open on the stay gets wrenched about, which bends the arms. Older stays made of plain steel can rust, especially near the coast, which stiffens them until something gives.

Means of escape: why like-for-like matters

On upstairs rooms used for sleeping, one window is often designed as an escape window. Planning Portal guidance sets out that an escape window should have a clear openable area of at least 0.33 m², with both width and height at least 450 mm, and the bottom of the opening no more than 1100 mm above the floor. Replacement windows should give at least the same potential for escape as the ones they replace.

The hinge is a big part of that. Egress and easy-clean stays leave a clear gap at the hinge side; a standard stay can leave the sash in the way. So when we replace hinges on a first-floor escape window, we fit the same type, or an egress type where appropriate, so the clear opening is not made smaller. If a window has a restrictor, it should be releasable by an adult on an escape window – see window restrictor fitting.

How we replace uPVC window hinges

1. We ask about the window – which floor, which room, how big, and what it is doing. A photo of the open window showing the hinge arms is helpful.
2. We measure and identify the hinge – length, stack height, type (standard, easy-clean, egress, restricted) and whether the sash is heavy enough to need a heavier-duty stay.
3. We support the sash safely while the old stays are removed and new ones fitted to the frame and sash.
4. We set the sash so it sits square in the frame, the gaps are even and the lock cams line up with the keeps.
5. We test it – opening, closing, the friction hold, and locking – before we leave.

Standard sizes can often be fitted at the first visit if we carry them. Less common lengths or types are ordered and fitted on a return visit.

Window hinges across Merseyside

Hinge wear is one of the most common jobs on uPVC windows that have been in for twenty years or more. Many houses in Maghull and post-war family housing in Halewood have first-generation windows where the stays are now tired. Near the coast in places like Wallasey, wind and salty air are hard on windows left open on their stays, so bent and rusted arms are more common. Wherever you are, our double glazing repairs across Liverpool and Merseyside include hinges on all floors.

Keeping your hinges working

• Do not leave windows open on the stay in strong wind; close them or use a restrictor position.
• Wipe the hinge tracks and apply a light oil or silicone spray once or twice a year, following the hardware maker’s advice.
• Do not hang anything from an open sash.
• If a window starts dropping or catching, get it looked at before it damages the lock gear or seals.

What affects the cost of a hinge repair?

The hinge type (egress and easy-clean stays cost more than standard ones), the size and weight of the sash, how many windows need doing, whether lock parts or seals also need replacing, and access to upstairs windows. We quote after measuring. If your windows are still under an installer’s guarantee, check the paperwork before arranging work. When the sash is back in line, the seals may still be worn – our window seal and gasket replacement page covers that.
