For landlords and businesses
We regularly price jobs from inventory or check-out pictures. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.
We’re used to working with agents and managing companies. Just send pictures, the address and how to get access and we will handle the rest.
How we handle uPVC repair in Celynnen
The damage is filled and refinished so it blends into the frame, woodgrain finishes included. We also do snagging repairs for builders. We’re frequently asked to fix holes from removed fittings and alarms and chips and dents, across white uPVC, doors & door panels and window frames & sills.
You’re covered for a year from the day of the repair. Just call us if there’s a problem and we’ll come back. Clean with warm soapy water and a soft cloth. Do not use solvents or scourers.

Celynnen questions
Do you hold any accreditations?
Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Is a repair better than a new one?
Normally, if the item is otherwise sound. A repair avoids removal and making good. If replacing would be better, we’ll say so.
Do the materials smell?
A little, depending on the job. Open windows and an extractor fan help.
Is it messy?
No. The work area is masked and covered, and we take our waste away with us.
Can I add another job to the visit?
Yes. Doing several items on one visit typically costs less than separate visits. Include pictures of each item.
Can a burnt window sill be fixed?
Yes. We fill and refinish the burnt area to match.
Do you charge for travel?
We do not add a call-out fee. The fixed price covers the visit and the work.
What areas do you cover?
We work UK-wide. Our prices are the same everywhere.
Prices and what affects them
Repairs from £95. There’s no charge for travel to Celynnen. The price depends on:
- How easy the damage is to reach
- What kind of damage it is
- The material
- How many items we do on one visit
The price reflects the work involved, not your postcode. The full price is agreed before you book, with no extras added later.
Getting a price from pictures
Almost every job we do is priced from pictures. This is what we need:
- A coin beside the damage so we can judge size
- A close-up of the damage, in focus
- What it’s made of, if you know
- Whether it’s been repaired or coated before
A quote takes minutes to ask for: photograph the damage, then the entire window, door or sill, add your postcode and send them to us. You will get a fixed quote, not an estimate.
What we are called out for in Celynnen
uPVC is tough but not indestructible: ladders, tools and building work scratch and chip it, candles and cigarettes burn sills, and old fittings leave holes.
Contact us if you’ve noticed any of these:
- Chips and dents
- Burns on sills
- Scratches from ladders and furniture
- Damage during building work
What to look for in a quote
- How long it needs to cure
- What protection goes down before work starts
- Aftercare advice
- Whether a trained technician does the job
DIY kit or professional repair?
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
If you’re set on a kit, follow its instructions closely, and give it the full curing time. If it fails, we can still put it right.
Should you replace it?
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. Our uPVC repair starts from £95. We do not add extras on the day. The price we quote from your pictures is the price you pay, and if the damage turns out to be different, we discuss it before starting.

- Finally we blend it into the rest of the frame.
