Crowthorne: uPVC window repairs
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.
Euro cylinders are the key barrels in most uPVC and composite doors. Standard cylinders can be vulnerable to lock snapping. Cylinders tested to TS 007 with a 3-star rating, or certified to Sold Secure SS312 Diamond, are designed to resist this type of attack.
Repairs usually take a single visit when the part can be identified and is carried on the van. Unusual or discontinued parts may need ordering. The glazier then returns to fit them, and in the meantime can usually leave the window or door secure and working.

Crowthorne at a glance
- Postcodes covered
- RG45, GU47, RG40 and the surrounding area, including Sandhurst, Yateley and Camberley
- Coast
- Crowthorne is well inland, around 59 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Crowthorne the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 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 England
- Approved Document Q applies to new homes in England, where doors and windows are expected to meet PAS 24 or an equivalent standard. It does not apply to replacements in existing homes, but PAS 24 products are still a sensible choice.

Window Repairs in Crowthorne: questions
Is my euro cylinder lock secure?
Many older euro cylinders can be snapped, which lets an intruder open the door. Look for markings on the cylinder face. A TS 007 3-star mark, or certification to Sold Secure SS312 Diamond, shows the cylinder has been tested to resist snapping. The glazier can check and replace the cylinder with one cut to fit your door.
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.
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.
