Frequently Asked Questions
How long do uPVC windows last?
Quality uPVC frames typically last 20–30 years before the profile begins to discolour or warp. Sealed units often fail sooner — typically 15–25 years — but can be replaced without changing the frame.
Can uPVC windows be cleaned?
Yes. uPVC frames clean easily with warm soapy water. Avoid abrasive cleaners which can scratch the surface. Coloured foil finishes should be cleaned with manufacturer-recommended products to preserve the finish.
Do uPVC windows reduce noise?
Double glazed uPVC windows with a standard sealed unit provide moderate noise reduction. For properties near Heathrow flight paths or busy roads, we recommend acoustic sealed units (typically 6-16-6.4 laminated glass) for meaningful noise reduction.
Is FENSA registration included?
Yes — always. Every replacement window installation we carry out is registered with FENSA. You'll receive a certificate confirming compliance with building regulations, which is needed when you sell your property.
