Common questions in Cwm-y-glo
Can you match woodgrain uPVC?
Yes. Colour and grain are matched by hand.
What happens after I send pictures?
You’ll get a fixed quote back. There’s no obligation to book.
Is it worth repairing rather than replacing?
Usually, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.

What else we do in Cwm-y-glo
What affects the price in Cwm-y-glo
Repairs from £95. You’ll know the full cost before you book. We take into account:
- Whether it’s a chip, crack, burn or wear
- What the surface is made of
- Doing more than one item at once
- Any earlier repairs that need removing first
A few things move the price: access, material, the extent of the damage and whether we can do several items together. Photos let us give you a fixed figure.
Send photos for a quote
Photographing the damage takes a minute. Please include:
- A close-up of the damage, in focus
- What it’s made of, if you know
- Where you are, by postcode
- A wider photo showing the whole window, door or sill
Getting a price is easy: snap the damage close up and then the whole item, send them over with your postcode, and we’ll reply with a fixed quote. There’s no charge for the quote and you’re under no obligation.
Repairing versus replacing in Cwm-y-glo
A new window, door or sill costs far more, and new uPVC may not match the weathered frames around it. A repair leaves the unit in place. Repairs from £95, with every job priced individually. There are no surprise 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.

What we’re called out for in Cwm-y-glo
uPVC is hard-wearing, but it does get damaged: ladders and building work leave scratches and chips, candles and cigarettes mark sills, and removed fittings leave holes.
The most common problems we’re called about are:
- Burns on sills
- Chips and dents
- Scratches from ladders and furniture
- Damage during building work
Before booking anyone
- Who turns up on the day
- How to care for the finish
- Whether there are any call-out or travel charges
- How long it needs to cure
Should I try a DIY kit first?
If you do try a kit, read the instructions carefully, ensure the area is clean and completely dry, and give it the full curing time. If it doesn’t work out, we can still repair it properly.
It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is typically the cheaper route.
How it works
Your technician turns up at the time we agreed with you, introduces themselves and looks over the damage before anything else. The floor and nearby surfaces are covered before we open a single tin. Most visits take a morning or an afternoon, and we leave the room as we found it.
- We start by cleaning the frame.
- We fill scratches, chips and holes.
- We smooth the repair.
- The finish is colour matched, woodgrain included.
- The repair is blended into the surface around it.
Getting ready for the visit
- Have somewhere for us to park nearby if possible
- Let us know about parking or access
- Make sure the area is dry
