Can I fix it myself?
DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and then the old filler has to be removed first.
Repair or replace: which is better?
Replacing the frame or sill is a much bigger job, and it may not match the rest after years of weathering. A repair keeps the original. Our uPVC repair starts from £95. A repair is priced on what needs doing, not where you live. You will see the full price before booking, with nothing added on the day.
Why book with us
- A year’s guarantee on all work
- Rooms protected and left tidy

Rental properties take more wear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.
Common questions in Dolgellau
Will the price change on the day?
We will show you and explain before doing anything extra. You won’t be charged for anything you haven’t agreed.

How it works
We turn up at the time we agreed with you, introduces themselves and looks over the damage before anything else. Dust sheets and masking tape go down before we open a single tin. The work itself takes a few hours, and we leave the room as we found it.
- We start by cleaning the frame.
- Scratches, chips and holes are filled.
- The repair is sanded smooth.
- We colour-match the finish, including woodgrain effects.
- The repair is blended into the surface around it.
Before we arrive
- Let us know which floor the room is on
- Tell us about any previous repairs or coatings
- Have somewhere for us to park nearby if possible
Ask for a price
For most jobs, photos are all we need to give you a price. Add a line about what happened and your postcode, and we’ll send back a fixed quote and some dates.
Advice
How we price uPVC repair
Repairs from £95. Every quote is fixed and free. What we take into account:
- The material
- How many items we do on one visit
- The type of damage
- Previous DIY repairs that have to come out
We charge the same wherever you are, so there is no premium for Dolgellau. What changes the price is the job itself: the material, the amount of damage and how many items.
Quotes from your pictures
You can typically get a fixed price without us visiting. To help us price it:
- Whether it’s been repaired or coated before
- Your postcode, so we can check dates
- Daylight if possible, and no flash reflection
- A coin beside the damage so we can judge size
You do not need a survey visit. Photos are enough for us to price nearly every job: we need a close-up, a wider picture and your postcode, and we’ll come back to you with a fixed figure.
What we can’t put right
We’ll always be straight with you, so here’s what a repair will not do:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square
