Window handle replacement in Caerphilly
Draught seals and gaskets compress and shrink over time, letting in cold air and noise. Replacing them with a matching profile restores the seal without changing the window. The glazier checks the gasket type, as frames from different makers often use different profiles.
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.
Sash windows run on cords and weights or on spring balances. A broken cord leaves the sash heavy or loose, and a weak balance makes it slide down. Replacing cords, rehanging the sash and easing the beads can make a sash window run smoothly again.
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 Caerphilly for this job
- Postcodes covered
- CF83, CF15 and the surrounding area, including Risca, Pontypridd and Nelson (Mid Glamorgan)
- Coast
- Caerphilly sits roughly 11 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. 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.
- Daylight and sun
- In Caerphilly 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 Wales
- Security rules for doors and windows differ between the UK nations. For replacement doors and windows in Wales, products tested to PAS 24 are a sensible benchmark.

Window Repairs in Caerphilly: 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.
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.
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.
