uPVC Repair in Cynwyd
uPVC repair in and around Cynwyd: a fixed quote from pictures, a tidy visit and a one-year guarantee.
- Repairs from £95
- Holes from removed fittings and alarms
- Damage during building work

Can I fix it myself?
A DIY attempt isn’t a disaster. We take the old repair out and do it properly, so it does not stop a professional repair. Just mention it when you send pictures, as it can add time.
If you are set on a kit, follow its instructions closely and work on a clean, dry surface, and give it the full curing time. If it does not work out, we can still repair it properly.
uPVC repair in Cynwyd without replacing anything
The damage is filled and refinished so it blends into the frame, including woodgrain finishes. We also do snagging repairs for builders. Common call-outs are for burns on sills and holes from removed fittings and alarms, across window frames & sills, conservatory frames and white uPVC.
Your repair is guaranteed for a year, as with every job we do. Clean with warm soapy water and a soft cloth. Avoid solvents and abrasive cleaners.

Landlords, agents and businesses in Cynwyd
Rented homes see more wear and tear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
Builders use us to fix snagging damage before handover, so there is no need to replace a damaged item at the last minute. Several plots can be done in one visit to keep costs down.
Prices and what affects them
Prices start from £95. Every quote is fixed and free. What we look at:
- The colour and finish to match
- Any earlier repairs that need removing first
- The size and number of damaged areas
- Whether we combine several jobs
No two jobs are quite the same, so each one is priced on its own. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.
How to get a fixed quote
Good pictures mean an accurate price. Here’s what helps:
- Natural light rather than flash
- One picture of the entire window, door or sill
- One sharp close-up of the damage
- Your postcode, so we can check dates
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 you’ll get a fixed figure back.
Why repair rather than replace?
A new window, door or sill costs far more, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. Prices start from £95. The price depends on the type and amount of damage, what it’s made of and how many jobs we combine into one visit. You get a fixed price from your pictures, so there are no surprises on the day.

Your questions about uPVC repair in Cynwyd
Is a repair better than a new one?
Normally, when the rest is in good condition. A repair avoids removal and making good. We’ll tell you honestly if replacement makes more sense.
Can you redo someone else’s repair?
Yes, regularly. It can add a little time, which we include in the quote.
Can you repair a burn on a uPVC sill?
Yes. We fill and refinish the burnt area to match.
Will there be a smell?
It depends on the job, but often a little. Open windows and an extractor fan help.
Are you accredited?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Can I add another job to the visit?
Of course, and it typically saves money. Just add the extra items to your photos and we’ll quote them together.
Is the work guaranteed?
Every repair comes with our one-year guarantee. Ask us what it covers when you get your quote.
Can tenants book a repair?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
