Farnham: window hinge replacement
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.
The cost of a window or door repair depends on the part needed, whether it is a standard or discontinued design, how easy it is to identify the make, the number of windows or doors, and access. Discontinued hardware sometimes needs a modern equivalent and adaptation to fit.
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.
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.

Working in Farnham
- Postcodes covered
- GU9, GU10 and the surrounding area, including Aldershot, Fleet and Farnborough
- Coast
- Farnham is well inland, around 42 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Farnham 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.

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 Farnham: questions
Do replacement window hinges need to allow escape in a fire?
In England, upper-floor bedroom windows are often relied on as escape windows. Replacement hinges should not reduce the opening below what the window gave before. Egress friction stays open wider than standard stays to give a clear opening, so the glazier checks the room and window before choosing the hinge type.
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.
Can sash windows be repaired instead of replaced?
Usually, yes. Broken sash cords, weak spring balances, sticking sashes and rattles can all be fixed on existing frames. The glazier replaces cords or balances, eases or replaces beads, and adds draught seals where needed. Repairing original sash windows also helps keep the character of older properties and conservation areas.
