Treharris questions
Do you work in Treharris?
Yes, we do. Technicians travel to Treharris from across the region, and the price is the same as everywhere else.
Is it worth repairing rather than replacing?
Typically, if the item is otherwise sound. A repair avoids removal and making good. We will tell you honestly if replacement makes more sense.
Do the materials smell?
There may be a mild smell during the work, which fades afterwards.
It’s been repaired before. Can you still fix it?
In most cases. The old repair comes out first.
What happens after I send pictures?
You get a fixed quote and available dates. If we need another angle, we will ask.
Can a burnt window sill be fixed?
Yes. The burn is filled and refinished to match.
How quickly can you book me in?
Your quote comes with available dates. If it’s urgent, say so and we’ll do what we can.
Which areas do you work in?

What uPVC repair costs
Repairs from £95. Each job gets its own fixed price. This is what makes a difference:
- What the surface is made of
- What kind of damage it is
- The size and number of damaged areas
- Unusual colours or finishes
We charge the same wherever you are, with no extra for Treharris. What changes the price is the job itself: the material, the amount of damage and how many items.
Getting a price from pictures
Most quotes are done from pictures alone. To make it quick:
- A clear, close picture of the problem area
- Any details about the material
- Good light, ideally daylight, without flash glare
- Details of any past repairs
Ring 0345 017 0787, or send us pictures through the quote form. With a clear picture of the damage and one of the entire window, door or sill, we can price the job without visiting.

DIY kit or professional repair?
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
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.
When we would advise against a repair
Some jobs aren’t right for a repair, including:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square
If in doubt, send pictures and we will say what we think.
Materials we repair
- Conservatory frames
- Window frames & sills
- Coloured and woodgrain uPVC
- White uPVC
- Doors & door panels
Repair or replace in Treharris?
A new window, door or sill is a much bigger job, and new uPVC may not match the weathered frames around it. A repair keeps the original. Prices start from £95. 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.
