Why repair rather than replace?
A new window, door or sill is a much bigger job, and it may not match the rest after years of weathering. A repair leaves the unit in place. Prices start from £95. Compared with replacing, a repair is generally a fraction of the price, because there’s no removal, plumbing or making good. The quote lists exactly what you’re paying for.

Work for landlords and builders
Hotels, guest houses and holiday lets need rooms back in use quickly, so we keep visits short and tidy. We will fit around changeovers where we can.
We regularly price jobs from inventory or check-out photos. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.

DIY repairs versus a professional job
If you do try a kit, read the instructions carefully, and give it the full curing time. If it does not work out, we can still repair it properly.
The difference between a kit and a professional repair is mostly in the preparation and colour. 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.
How it works
We begin by going over the job with you, so there are no surprises. After that, protection goes down around the work area and we start. You can expect it to take a few hours, and we will keep you posted as we go.
- We start by cleaning the frame.
- Scratches, chips and holes are filled.
- The repair is sanded smooth.
- The finish is colour matched, woodgrain included.
- We blend the repair into the surrounding surface.
Preparing for the visit
- Ensure the area is dry
- Plan for the room to be out of bounds to pets and children
- Keep a parking space free if you can

FAQs for Llanllyfni
Is repairing better than replacing?
In most cases, yes. A repair skips the removal, fitting and redecorating. If it is not worth repairing, we’ll tell you.

Yes. The burn is filled and refinished to match.
How do I book?
Use the quote form or ring 0345 017 0787, and we’ll do the rest.
Can you do more than one item on the same visit?
Yes. Combining jobs on one visit brings the cost down. Include pictures of each item.

We review the photos and send a fixed quote and the next dates we have.
Do you repair coloured uPVC?
Yes. Colour and grain are matched by hand.

What uPVC repair costs
Repairs from £95. We price every job individually, from your pictures. What matters most is:
- How hard the colour is to match
- Whether old repairs or coatings need taking off
- The material
- The type of damage
Every job is a little different, 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 combining jobs on one visit brings the cost down.
How to get a fixed price
Photographing the damage takes a minute, and it saves a visit. Try to send:
- One picture of the whole window, door or sill
- Natural light rather than flash
- What it’s made of, if you know
- One sharp close-up of the damage
Upload a picture of the damage and a wider shot of the whole item, and tell us you’re in Llanllyfni, and we’ll reply with a fixed price.
