Why repair rather than replace?
A new window, door or sill costs far more, and new uPVC may not match the weathered frames around it. Repairing the damage leaves the unit in place. Our uPVC repair starts from £95. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.
Why us?
- A fixed quote before you book
- We leave the room as we found it

What affects the price in Bonvilston
Prices start from £95. We give every job a fixed price from photos. This is what makes a difference:
- What kind of damage it is
- The material and finish
- How many areas need work
- How many items we do on one visit
Most people are surprised how affordable a repair is, particularly next to the cost of replacement. Send pictures and we’ll give you the exact figure.
Getting a price from pictures
Photographing the damage takes a minute, and it saves a visit. Please include:
- A picture taken from further back
- Daylight if possible, and no flash reflection
- What it’s made of, if you know
- Any earlier repairs or coatings
A quote takes minutes to ask for: take one close-up and one wider shot of the window, door or sill, add your postcode and send them to us. You will get a fixed price, not an estimate.

Bonvilston: your questions answered
Are there extra charges for Bonvilston?
We don’t add a call-out fee. The fixed quote covers the visit and the work.
Is it worth repairing rather than replacing?
Typically, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.
Do you come to Bonvilston?
Yes. We cover the whole UK and come to Bonvilston and the rest of Cardiff. Send photos and we’ll quote, or call 0345 017 0787.
Do the materials smell?
There may be a mild smell during the work, which fades afterwards.
Which areas do you work in?
Across the UK, and that includes Bonvilston. Prices do not change with location.
Can a burnt window sill be fixed?
Yes. We fill and refinish the burnt area to match.
Is it OK to have pets in the house?
Just keep them out of the work area. We’ll tell you when the room can be used again.
Do you repair coloured uPVC?
Yes. Colour and grain are matched by hand.
DIY repairs versus a professional job
A DIY attempt isn’t a disaster. We remove the old filler and start again, so it will not stop us repairing it. It does add a little time, so tell us about it when you send photos.
For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.
What happens on the day
Once we are through the door, the aim is to do the job without disturbing the rest of your home. We mask off everything nearby, the work takes a morning or an afternoon, depending on what we find, and we finish with a tidy-up and a look at the finished work together.
- We start by cleaning the frame.
- We fill scratches, chips and holes.
- We smooth the repair.
- We colour-match the finish, including woodgrain effects.
- We blend the repair into the surrounding surface.
Getting ready for the visit
- Keep pets and children out of the room while we work
- Have a window or extractor fan available
- Keep a parking space free if you can
How to get a price
