Why repair rather than replace?
A new window, door or sill costs far more, and new uPVC may not match the weathered frames around it. A repair keeps the original. Our uPVC repair starts from £95. There are no surprise extras on the day. The price we quote from your photos is the price you pay, unless the damage turns out to be different, in which case we talk to you first.

Advice
What affects the price in St Nicholas and Bonvilston
Prices start from £95. Quotes are free and the price is fixed. What we look at:
- Whether we combine several jobs

Getting a price from pictures
It only takes a minute to photograph the damage, and it saves a visit. Try to send:

What else we do in St Nicholas and Bonvilston
Do you need uPVC repair in St Nicholas and Bonvilston?
uPVC is hard-wearing, but it does get damaged: ladders, tools and building work scratch and chip it, candles and cigarettes mark sills, and removed fittings leave holes.
People generally call us when they notice one of these:
- Burns on sills
- Damage during building work
- Chips and dents
- Scratches from ladders and furniture
Questions to ask before you book
- When it can be used again
- What happens if they find more damage
- Whether the colour is mixed to match
- Whether the price covers travel
DIY kit or professional repair?
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and do not use it until it has fully cured. If it fails, we can still put it right.
