Purley: dropped uPVC door repair
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.
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.
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.
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.

About Purley for this job
- Postcodes covered
- CR8, CR2, CR5 and the surrounding area, including Coulsdon, South Croydon and Wallington
- Coast
- Purley is well inland, around 36 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Purley 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.

Window Repairs in Purley: 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.
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.
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.
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.
