About our uPVC repair in Carmel
The damage is filled and refinished so it blends into the frame, including woodgrain finishes. Builders and developers use us for snagging repairs too. Our technicians work on coloured and woodgrain uPVC, window frames & sills and white uPVC, and people most often call us about damage during building work and holes from removed fittings and alarms.
Every repair comes with a one-year guarantee. Warm soapy water and a soft cloth are all it needs. Avoid solvents and abrasive cleaners.

DIY repairs versus a professional job
It’s tempting to reach for a kit, but the repairs we redo most often are DIY ones that have discoloured or lifted. Doing it properly first is usually the cheaper route.
It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.
How we price uPVC repair
Repairs from £95. There are no hourly rates or hidden extras. The price depends on:
- How many areas need work
- The material and finish
- The type of damage
- Unusual colours or finishes
We don’t add extras on the day. The price we quote from your photos is the price you pay, unless the damage turns out to be different, in which case we talk to you first.
Send photos for a quote
You can take the pictures on your phone, there’s no need for anything special. Ensure they show:
- One picture of the whole window, door or sill
- A coin beside the damage so we can judge size
- Natural light rather than flash
- A clear, close picture of the problem area
We price from photos so you don’t have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and we will come back with a fixed figure.
Repairing versus replacing in Carmel
A new window, door or sill is a much bigger job, and it may not match the rest after years of weathering. Repairing the damage keeps the original. Our uPVC repair starts from £95. Set against the cost of replacement, a repair is typically a fraction of the price, because nothing has to be taken out, refitted or made good. Your fixed quote shows exactly what’s included.

Common questions in Carmel
Can a burnt window sill be fixed?
Yes. We fill and refinish the burnt area to match.
Is repairing better than replacing?
Normally, if the item is otherwise sound. A repair avoids removal and making good. If replacing would be better, we will say so.
Can you match woodgrain uPVC?
Yes. We recreate the colour and grain by hand.
Will it make a mess?
We protect the room with dust sheets and masking first, and we clean up when we’ve finished.
What information do you need?
Some photos, your postcode and how to reach you. On the day, access to the room.
Is it safe with children and pets around?
Please keep children and pets out of the room during the visit. Everywhere else in the home is fine.
Do you come to Carmel?
Yes, we do. We send a technician to Carmel for every job, and the price is the same as everywhere else.
Do you charge for travel?
There is no separate call-out charge. The fixed price covers the visit and the work.
