About window hinge replacement in Finchley
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.
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.
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.
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.

Finchley at a glance
- Postcodes covered
- N3, N12, N2 and the surrounding area, including Muswell Hill, Cricklewood and Wood Green
- Coast
- Finchley is well inland, around 42 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Finchley 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
- In flats and terraced homes, working on upper-floor windows may need to be done from inside. Security matters on street-facing doors, so anti-snap cylinders and secure handles are worth considering. Parking near the property can affect access.
- 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 Finchley: 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.
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.
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 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.
