Why repair rather than replace?
Replacing the frame or sill is a much bigger job, and it may not match the rest after years of weathering. Repairing the damage keeps the original. Prices start from £95. There are no surprise extras on the day. What we quote from your photos is what you pay, unless the damage turns out to be different, in which case we talk to you first.

How we price uPVC repair
Repairs from £95. There’s no charge for travel to St Martin. The price depends on:
- Any earlier repairs that need removing first
- The material and finish
- The type of damage
- Unusual colours or finishes
We charge the same wherever you are, so there’s no premium for St Martin. What changes the price is the job itself: how much damage, what it’s made of and how many items.
Getting a price from pictures
Before you send photos, these tips help us give you a firm price:
- The postcode, so we can plan the visit
- What it’s made of, if you know
- Natural light rather than flash
- Any earlier repairs or coatings
You do not need a survey visit. Photos are enough for us to price nearly every job: send a close-up, a wider shot and your postcode, and we will reply with a fixed quote.

Should I try a DIY kit first?
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.
If you are set on a kit, follow its instructions closely, ensure the area is clean and completely dry, and do not use it until it has fully cured. If it fails, we can still put it right.
Your questions about uPVC repair in St Martin
Do you do work for letting agents?
Yes. We carry out repairs for householders, landlords, letting agents, builders and businesses across Cornwall.
Do you repair coloured uPVC?
Yes. We recreate the colour and grain by hand.
Can I add another job to the visit?
Yes. Combining jobs on one visit brings the cost down. Include photos of each item.
Can pets and children be at home?
Keep pets and children away from the work area on the day, so the repair is not disturbed while it cures.
How quickly can you book me in?
We will give you dates with your quote. Tell us if you need it done quickly.
Do the materials smell?
There can be some smell while we work. It fades as everything cures.
What if the damage is worse than the pictures show?
We stop, show you and agree any change before carrying on. You won’t be charged for anything you haven’t agreed.
Does someone need to be in?
Yes. We need access to the room while we work, at a time we agree with you.
