Prices and what affects them
Prices start from £95. You will know the full cost before you book. We look at:
- Whether we combine several jobs
- Any earlier repairs that need removing first
- What the surface is made of
- The colour and finish to match
We don’t add extras on the day. What we quote from your photos is what you pay, unless the damage turns out to be different, in which case we talk to you first.
How to get a fixed quote
Two or three clear photos are generally enough. It helps if you send:
- Your postcode, so we can check dates
- Good light, ideally daylight, without flash glare
- A wider photo showing the entire window, door or sill
- A clear, close picture of the problem area
Send us pictures of the damage and a wider shot of the entire item, and tell us you’re in Coswinsawsin, and we’ll reply with a fixed price.
Why repair rather than replace?
Replacing the frame or sill is a much bigger job, and new uPVC may not match the weathered frames around it. Repairing the damage keeps the original. Our uPVC repair starts from £95. A repair is priced on what needs doing, not where you live. You will see the full price before you book, with nothing added on the day.

No. Our quotes include travel, and we charge the same wherever you are.
What if the damage is worse than the pictures show?
It’s rare, but if it happens we talk to you first. The price only changes if you agree.
Can I add another job to the visit?
Of course, and it normally saves money. Send pictures of everything together and we’ll quote them together.

What else we do in Coswinsawsin
Can I fix it myself?
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is generally the cheaper route.
It’s natural to want to try a repair yourself. The trouble is that kit repairs frequently look fine at first and then fail, and then the old filler has to be removed first.
