What uPVC repair costs
Repairs from £95. Each job gets its own fixed quote. These are the things that affect it:
- How many areas need work
- Where the damage is and how we get to it
- Previous DIY repairs that have to come out
- The material and finish
Rather than charging by the hour, we price the whole job up front. It depends on the damage, the material and access, and doing several items at once reduces it.
How to get a fixed quote
We price nearly every job from photos. This is what to send:
- Where you are, by postcode
- One sharp close-up of the damage
- The material, if you know it
- One picture of the whole window, door or sill
There is no need for us to visit first. Nearly every job can be priced from photos: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed price.

Why repair rather than replace?
A new window, door or sill is a much bigger job, and new uPVC may not match the weathered frames around it. A repair leaves the unit in place. If your window, door or sill in Mountain Ash West is sound, a repair is normally the better choice.
Our uPVC repair starts from £95. Every job is a little different, so each one is priced on its own. The size and type of damage, the material and access all play a part, and doing several things on one visit costs less than separate visits.
