Greater London: dropped uPVC door repair
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.
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.
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.
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.

What applies in Greater London
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.
Parts of Greater London are within about 15 km of the coast, where exposure to wind and salt air is worth planning for. 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.
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.

Window Repairs in Greater London: 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.
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.
