Repair or replace: which is better?
Replacing the frame or sill costs far more, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. Prices start from £95. No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.

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, then guarantee it for a year.
A DIY attempt isn’t a disaster. We take the old repair out and do it properly, so it will not stop us repairing it. It does add a little time, so tell us about it when you send photos.
What uPVC repair costs
Repairs from £95. There are no hourly rates or hidden extras. The price depends on:
- How many areas need work
- The material and finish
- How many items we do on one visit
- Unusual colours or finishes
We don’t add extras on the day. What we quote from your pictures is what you pay, and if the damage turns out to be different, we discuss it before starting.

How it works
You do not need to empty the room beforehand. Everything we use comes in the van with us, put protection down and get going once we’ve agreed what we’re doing. It normally takes a few hours, and you can get on with other things while we are there.
- We start by cleaning the frame.
- Scratches, chips and holes are filled.
- We smooth the repair.
- We colour-match the finish, including woodgrain effects.
- The repair is blended into the surface around it.
How to prepare
- Keep pets and children out of the room while we work
- Let the surface dry out before the visit
- Move bottles, mats and clutter away from the area
