uPVC Repair for Tŷ Sign homes
Damaged window, door or sill in Tŷ Sign? We repair it in place, mix the colour on the day and guarantee the work for a year.
- Repairs from £95
- Damage during building work

DIY repairs versus a professional job
If you’ve already tried a DIY fix, that is fine. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
About our uPVC repair in Tŷ Sign
Builders and developers use us for snagging repairs too. The damage is filled and refinished so it blends into the frame, woodgrain finishes included. We work on white uPVC, doors & door panels and conservatory frames, and people most frequently call us about scratches from ladders and furniture and chips and dents.
Peace of mind is built in: our one-year guarantee applies to every job, and we explain what it covers before you book. Warm soapy water and a soft cloth are all it needs. Avoid solvents and abrasive cleaners.

Landlord and trade work in Tŷ Sign
We work for landlords, letting agents and housing providers in Tŷ Sign as well as homeowners. A repair between tenants keeps the property empty for less time, and it typically costs far less than a refit.

What else we do in Tŷ Sign
Tŷ Sign: your questions answered
How do I book?
Send pictures through the quote form or call 0345 017 0787.
Can tenants book a repair?
Yes, but check with your landlord or agent first. Many landlords are happy for a repair to be arranged.
Can you price it without visiting?
Yes, almost always. A close-up and a wider photo are enough to give a fixed price.
Is there a call-out fee?
No. Our quotes include travel, with the same prices everywhere we work.
Do I have to be there?
We need someone to let us in. After that, you can carry on with your day.
Can I add another job to the visit?
Yes. Doing several items on one visit generally costs less than separate visits. Include photos of each item.
Are you accredited?
We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
What happens if you find more damage?
It’s rare, but if it happens we talk to you first. You decide whether to go ahead.
How the visit works
Arrival times are agreed in advance, so you know when to expect us. Once we’re there, the work takes a morning or an afternoon for most jobs. We leave the room clean and ready to use once it has cured.
- We start by cleaning the frame.
- Next we fill the damage.
- We sand the repair smooth.
- We colour-match the finish, including woodgrain effects.
- The repair is blended into the surface around it.
Preparing for the visit
- Keep a parking space free if you can
- Have a window or extractor fan available
- Ensure the area is dry
How to get a price
There is no need for us to visit first. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll come back to you with a fixed figure.
Related advice
Signs you need uPVC repair in Tŷ Sign
uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes mark sills, and old fittings leave holes.
These are the problems we’re asked about most:
- Burns on sills
- Damage during building work
- Holes from removed fittings and alarms
- Chips and dents
Before booking anyone
- What protection goes down before work starts
- Is the price fixed, and does it include VAT?
- Whether the colour is mixed to match
- Whether the price covers travel
Prices and what affects them
Prices start from £95. Every quote is fixed and free. What we take into account:
- Access to the area
- Doing more than one item at once
- Previous DIY repairs that have to come out
- Unusual colours or finishes
What it costs depends on how much damage there is and what kind, what it’s made of and how many jobs we combine into one visit. We give a fixed price from your pictures, so there are no surprises on the day.
Quotes from your pictures
Before you send pictures, these tips help us give you a firm price:
- A clear, close picture of the problem area
- Your postcode, so we can check dates
- Something in shot to show the size
- One picture of the whole window, door or sill
No survey visit is needed: we price from pictures. Use the quote form, or ring 0345 017 0787 to talk it through, and you will get a fixed figure back.
Repair or replace: which is better?
Replacing the frame or sill costs far more, and new uPVC may not match the weathered frames around it. Repairing the damage leaves the unit in place. Repairs from £95, with every job priced individually. A repair is priced on what needs doing, not where you live. You’ll see the full price before booking, with no extras added later.
