uPVC window repairs in County Down

A uPVC or composite door with a multipoint lock has one central gearbox that drives hooks, rollers or bolts along the door edge. A failed gearbox can leave the door stuck locked or unable to lock. In many cases only the gearbox needs replacing, not the whole strip.

Friction stays are the hinges on most uPVC and aluminium casement windows. When the sliding shoe wears or the arms bend, the window drops, binds or will not stay open. Replacements must match the stay's length, stack height and type, which the glazier measures before ordering.

Most modern windows use an espagnolette lock: a metal bar in the sash edge that moves locking cams into keeps on the frame when the handle turns. If the handle feels stiff or spins freely, the gearbox or bar may be worn, rather than the handle itself.

Draught seals and gaskets compress and shrink over time, letting in cold air and noise. Replacing them with a matching profile restores the seal without changing the window. The glazier checks the gasket type, as frames from different makers often use different profiles.

What applies in County Down

For replacement doors and windows in Northern Ireland, PAS 24 products are a sensible choice for security.

Where a window provides an escape route, its replacement in Northern Ireland should give at least the same escape opening as before.

County Down has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Near the coast, salt air corrodes window and door hardware more quickly, especially hinges, keeps and lock mechanisms. Stainless steel friction stays and corrosion-resistant hardware last longer, and regular cleaning and lubrication help keep moving parts free.

Older rural homes may have timber casements, sash windows or doors with discontinued hardware, so parts may need matching or adapting. Exposed sites put more strain on hinges and seals, and outbuildings often benefit from upgraded locks.

Window Repairs in County Down: questions

What does it cost to replace a window hinge or door lock?

The cost depends on the part, whether it is standard or discontinued, how many windows or doors need work, and access. Gearboxes and full multipoint strips cost more than a single handle or cylinder. See the guide prices for typical repairs, then get a written quote once the glazier has identified the exact part needed.

My door handle spins and the door will not lock. What is wrong?

A handle that spins without moving the lock usually means the gearbox inside the door has failed, or the spindle connecting handle and gearbox has broken. The gearbox can often be replaced on its own. If the door is stuck locked, the glazier can usually open it without damaging the frame before fitting the new part.

How can I stop draughts from my existing windows?

Draughts often come from worn gaskets, a sash that has dropped or keeps that no longer pull the sash tight. Replacing the gaskets with a matching profile and adjusting the keeps or hinges usually fixes the problem. If draughts come through the frame or glass seals, the glazier will say what else needs attention.

Can you find parts for old or discontinued windows?

Often, yes. Many hinges, locks and gearboxes are made to common sizes, and modern equivalents exist for many older designs. The glazier measures key dimensions such as backset, length and stack height. If an exact match is not available, the quote will explain the nearest option and any adaptation needed.
