Door lock repair across Coleraine
Window restrictors limit how far a window opens, which can help reduce the risk of falls from upper floors. Many restrictors can be released by an adult, so the window can still be opened fully for escape or cleaning. They can usually be fitted to existing windows.
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.
Sash windows run on cords and weights or on spring balances. A broken cord leaves the sash heavy or loose, and a weak balance makes it slide down. Replacing cords, rehanging the sash and easing the beads can make a sash window run smoothly again.
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.

About Coleraine for this job
- Postcodes covered
- BT52, BT55 and the surrounding area, including Portstewart, Ballymoney and Limavady
- Coast
- Coleraine sits roughly 6 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. 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.
- Daylight and sun
- In Coleraine the midwinter sun reaches about 11° above the horizon at noon, with roughly 6.9 hours of daylight, rising to about 58° and 17.1 hours in midsummer. Windows and doors on sunny elevations expand and contract more with temperature, which can make them stick in summer and catch the frame. Dark-coloured doors absorb more heat, so hinge adjustment may be needed after hot spells.
- Access and setting
- 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.
- Rules in Northern Ireland
- For replacement doors and windows in Northern Ireland, PAS 24 products are a sensible choice for security.

Window Repairs in Coleraine: questions
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.
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.
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.
Can you repair a uPVC window that will not close properly?
Usually, yes. Windows that will not close are most often caused by worn or bent friction stays, a sash that has dropped, or a locking cam catching the keep. The glazier identifies the fault, then replaces the hinges, adjusts the keeps or repacks the sash so it closes and locks properly again, keeping the existing frame and glass.
