What uPVC repair costs
Repairs from £95. We charge the same across the UK, including Llandderfel. What changes the price is:
- The size and number of damaged areas
- How easy the damage is to reach
- Unusual colours or finishes
- How many items we do on one visit
A repair is priced on what needs doing, not where you live. You will see the full price before booking.
Quotes from your pictures
We price nearly every job from pictures. This is what we need:
- Any earlier repairs or coatings
- A wider photo showing the entire window, door or sill
- Any details about the material
- A close-up of the damage, in focus

DIY repairs versus a professional job
What a professional repair adds is preparation, colour matching and finishing. 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.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is normally cheaper.
