What uPVC repair costs
Prices start from £95. We give every job a fixed quote from pictures. These are the things that affect it:
- Whether we combine several jobs
- The material and finish
- How hard the colour is to match
- How many areas need work
There are no surprise extras on the day. What we quote from your pictures is what you pay, unless the damage turns out to be different, in which case we talk to you first.
Quotes from your pictures
Almost every job we do is priced from pictures. This is what we need:
- Where you are, by postcode
- A close-up of the damage, in focus
- Whether it’s been repaired or coated before
- The material, if you know it
Ring 0345 017 0787, or send us photos through the quote form. With a clear picture of the damage and one of the entire window, door or sill, we can give you a fixed quote the same day in most cases.
uPVC repair in Tre-Derwen, done in place
We fill and refinish the damage so it blends into the frame, including woodgrain finishes. Builders and developers use us for snagging repairs too. We regularly repair conservatory frames, white uPVC and coloured and woodgrain uPVC, and people most often call us about burns on sills and chips and dents.
The work is guaranteed for twelve months. If something is not right in that time, we come back and put it right. Warm soapy water and a soft cloth are all it needs. Avoid solvents and abrasive cleaners.

Repair or replace: which is better?
Replacing the frame or sill is a much bigger job, and it may not match the rest after years of weathering. A repair leaves the unit in place. Our uPVC repair starts from £95. No two jobs are quite the same, so we price each one individually. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.

Advice
DIY repairs versus a professional job
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.
