What uPVC repair costs
Prices start from £95. We give every job a fixed price from pictures. This is what makes a difference:
- Doing more than one item at once
- How hard the colour is to match
- What kind of damage it is
- The material
A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send photos and you will get a fixed figure.
Getting a price from pictures
Good photos mean an accurate price. Here’s what we find most useful:
- Details of any past repairs
- A picture taken from further back
- Where you are, by postcode
- Daylight if possible, and no flash reflection
Getting a price is easy: snap the damage close up and then the entire item, send them over with your postcode, and we’ll reply with a fixed quote. There’s no charge for the quote and you are under no obligation.

Common questions in Llandaff North
Is there a call-out fee?
We don’t add a call-out fee. The fixed quote covers the visit and the work.
Do you do work for letting agents?
Yes, often. We can quote for several properties together and work between tenancies.
Is it OK to have pets in the house?
Just keep them out of the work area. We will tell you when the room can be used again.
Do you hold any accreditations?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Is it worth repairing rather than replacing?
Normally, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. If replacing would be better, we’ll say so.
It’s been repaired before. Can you still fix it?
Most of the time. Tell us what was done before and we will plan for it.
What happens after I send pictures?
You get a fixed quote and available dates. If we need another angle, we will ask.
Can you repair several things at once?
Yes. Doing several items on one visit typically costs less than separate visits. Send photos of everything you’d like done.
For landlords and businesses
If you manage property in Llandaff North, we can repair and quote for several addresses together. Just send pictures for each address and we will come back with a combined price.
We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover. We are CHAS, Constructionline and SafeContractor accredited.

DIY kit or professional repair?
We understand the appeal of fixing it yourself. The trouble is that kit repairs often look fine at first and then fail, and the old filler has to come out before a proper repair.
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.
What we are called out for in Llandaff North
uPVC is hard-wearing, but it does get damaged: ladders and building work leave scratches and chips, candles and cigarettes mark sills, and old fittings leave holes.
If you can see any of these, send us a picture:
- Damage during building work
- Scratches from ladders and furniture
- Burns on sills
- Holes from removed fittings and alarms
What to look for in a quote
- The length of the guarantee and what it covers
- How changes to the job are handled
- Whether they match the colour on site
- When it can be used again
When we would advise against a repair
Some problems need a builder, plumber or fitter rather than us:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square
If in doubt, send pictures and we’ll say what we think.
Materials we repair
- Coloured and woodgrain uPVC
- Doors & door panels
- Conservatory frames
- Window frames & sills
- White uPVC
