What else we do in Llanystumdwy
Should you replace it?
A new window, door or sill costs far more, and new uPVC may not match the weathered frames around it. Repairing the damage keeps the original. Prices start from £95. A repair is priced on what needs doing, not where you live. You will see the full price before you book.

How we price uPVC repair
Repairs from £95. We do not charge extra for travel to Llanystumdwy. The price comes down to:
- How much damage there is
- Previous DIY repairs that have to come out
- The colour and finish to match
- How many items we do on one visit
Instead of hourly rates, we fix the price before we start. Damage, material and access decide it, and doing several items at once reduces it.
Getting a price from photos
Two or three clear photos are generally enough. It helps if you send:
- Any earlier repairs or coatings
- What it’s made of, if you know
- Natural light rather than flash
- Your postcode, so we can check dates
Send us a picture of the damage and a wider shot of the whole item, with your LL52 postcode, and we will come back with a fixed quote.
FAQs for Llanystumdwy
Can you price it without visiting?
In nearly every case. If photos do not show enough, we’ll ask for another angle.
Do the materials smell?
There may be a mild smell during the work.
Is it safe with children and pets around?
We ask you to keep children and pets out of the room while we work. The rest of the house is unaffected.
Is there a guarantee?
Every repair comes with our one-year guarantee. Ask us what it covers when you get your quote.
What areas do you cover?
The entire UK, including all of Gwynedd. Send your postcode with your photos and we’ll offer you dates.
How do I book?
Just photos, your postcode and a contact number. On the day, we only need access to the room.
Can you repair several things at once?
Yes. Doing several items on one visit typically costs less than separate visits. Send pictures of everything you’d like done.
Will it make a mess?
We protect the room with dust sheets and masking first, and tidy up before we leave.
DIY repairs versus a professional job
If you’re set on a kit, follow its instructions closely, make sure the area is clean and completely dry, and give it the full curing time. If it fails, we can still put it right.
Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Getting it right first time is normally cheaper.

uPVC is tough but not indestructible: ladders, tools and building work scratch and chip it, candles and cigarettes burn sills, and removed fittings leave holes.
It’s worth getting a quote if you see:
- Damage during building work
- Chips and dents
- Holes from removed fittings and alarms
- Burns on sills
What to look for in a quote
- Who turns up on the day
- How the colour is matched
- Aftercare advice
- Whether the price is fixed and includes VAT
