uPVC repair in Trethowel without replacing anything
We fill and refinish the damage to match the frame, woodgrain finishes included. Builders and developers use us for snagging repairs too. Common call-outs are for holes from removed fittings and alarms and damage during building work, in conservatory frames, doors & door panels and white uPVC.
A one-year guarantee comes with the work, just as it does everywhere we cover. Clean with warm soapy water and a soft cloth. Do not use solvents or scourers.

Should you replace it?
Replacing the frame or sill costs far more, and it may not match the rest after years of weathering. A repair leaves the unit in place. Prices start from £95. Instead of hourly rates, we price the whole job up front. It depends on the damage, the material and access, and doing several items at once reduces it.

How it works
Once we are through the door, we keep the work contained to the one room. We mask off everything nearby, the work takes a few hours, and we finish with a tidy-up and a look at the finished work together.
- First the frame or panel is cleaned.
- Scratches, chips and holes are filled.
- We smooth the repair.
- The finish is colour matched, woodgrain included.
- Finally we blend it into the rest of the frame.
Before we arrive
- Tell us about any previous repairs or coatings
- Keep pets and children out of the room while we work
- Mention if the room is upstairs or in a flat

Prices and what affects them
Prices start from £95. Prices are worked out job by job. The main factors are:
- Access to the area
- The type of damage
- The size and number of damaged areas
- Whether old repairs or coatings need taking off
Compared with replacing, a repair is typically a fraction of the price, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.
Getting a price from pictures
It only takes a minute to photograph the damage, and it saves a visit. Please include:
- Your postcode, so we can check dates
- The material, if you know it
- A wider photo showing the whole window, door or sill
- A close-up of the damage, in focus
For a price in Trethowel, photos are the quickest way: one close up, one from further back, plus your postcode. You will get a fixed quote with dates to choose from.

DIY kit or professional repair?
For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.
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.
