uPVC window repairs across Daventry
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.
Simple care keeps hardware working longer. Clean tracks and keeps, then apply a light lubricant to moving parts once or twice a year. Keep drainage slots clear. Avoid slamming doors or forcing handles, as this strains gearboxes and can cause a door to drop over time.
In England, upper-floor windows serving bedrooms often double as escape windows. Replacing hinges with restricted-opening stays can reduce the opening below what is needed. Egress hinges give a wider opening for escape, so the glazier checks which type the window needs before fitting.
A door that drags on the threshold, catches the frame or needs lifting to lock has usually dropped. Doors can often be adjusted using the hinges and by repacking the glass or panel so the door sits square again. Adjustment is usually tried before replacing parts.
What a typical job includes
- Survey and diagnosis of the faulty part
- Adjustment of dropped or sticking doors and sashes
- Removal of old parts and packaging
- Matched replacement hinges, stays, handles or locks

Local details for Daventry
- Postcodes covered
- NN11 and the surrounding area, including Rugby, Northampton and Leamington Spa
- Coast
- Daventry is well inland, around 99 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Daventry the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 61° and 16.5 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.

Approved Document B covers escape windows. Where an existing window is an escape route, typically in first-floor bedrooms, its replacement should give at least the same escape opening as before.

Window Repairs in Daventry: questions
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.
Why has my uPVC door dropped and can it be fixed?
Doors drop when hinges wear or loosen, or when the glass or panel slips inside the door and stops supporting it square. Signs include dragging on the threshold and needing to lift the handle hard to lock. Most dropped doors can be fixed by adjusting the hinges and repacking the glass or panel, without replacing the door.
How do I look after window and door hardware?
Clean dirt from tracks, keeps and hinges, then apply a light machine oil or silicone spray to moving parts once or twice a year. Keep frame drainage slots clear. Do not force handles that feel stiff, as this can break gearboxes. Report a dropping door or sticking handle early, as small adjustments are easier than replacing parts.
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.
