What else we do in Trinant
Repair or replace: which is better?
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. Prices start from £95. The price reflects the work involved, not your postcode. The full price is agreed before booking, with no extras added later.

Nothing needs to be moved out of the room beforehand. We bring everything we need with us, lay protective sheets and start once you’re happy with the plan. Most jobs take a morning or an afternoon, and you are welcome to carry on with your day while we work.
- We clean the frame or panel.
- Scratches, chips and holes are filled.
- We sand the repair smooth.
- We colour-match the finish, including woodgrain effects.
- Finally we blend it into the rest of the frame.

Prices and what affects them
Repairs from £95. There is no charge for travel to Trinant. The price depends on:
- How easy the damage is to reach
- What kind of damage it is
- Whether we combine several jobs
- Whether old repairs or coatings need taking off
A repair generally costs much less than people expect, particularly next to the cost of replacement. Send photos and we’ll give you the exact figure.
How to get a fixed quote
Photographing the damage takes a minute, and it saves a visit. Try to send:
- A coin beside the damage so we can judge size
- One picture of the whole window, door or sill
- Natural light rather than flash
- Whether it’s been repaired or coated before
Send us photos of the damage and a wider shot of the entire item, and tell us you’re in Trinant, and we will reply with a fixed quote.
DIY repairs versus a professional job
If you’re set on a kit, follow its instructions closely and work on a clean, dry surface, and do not use it until it has fully cured. If it does not work out, we can still repair it properly.
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, and the work is guaranteed.
