What we’re called out for in Grendon Underwood
uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes burn sills, and removed fittings leave holes.
If you can see any of these, send us a picture:
- Burns on sills
- Chips and dents
- Holes from removed fittings and alarms
- Damage during building work
Before you book anyone
- Who will actually do the work
- How the colour is matched
- Whether cleaning and preparation are in the price
- If travel is included in the price
Prices and what affects them
Prices start from £95. We give every job a fixed quote from pictures. This is what makes a difference:
- Where the damage is and how we get to it
- What the surface is made of
- Whether it’s a chip, crack, burn or wear
- How many areas need work
Rather than charging by the hour, we price the entire job up front. Damage, material and access decide it.
Getting a price from photos
You can take the photos on your phone. Just ensure we can see:
- Daylight if possible, and no flash reflection
- A coin beside the damage so we can judge size
- A wider photo showing the entire window, door or sill
- What it’s made of, if you know
Getting a price is easy: take a close-up of the damage and a photo from further back, send them to us with your postcode, and you’ll get a fixed price back. There is no charge for the quote and no obligation.

Can I fix it myself?
It’s natural to want to try a repair yourself. The trouble is that kit repairs frequently look fine at first and then fail, and then the old filler has to be removed first.
A DIY attempt isn’t a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. Just mention it when you send photos, as it can add time.
When a repair is not the answer
Honesty matters more than a booking, 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
Send us photos and we’ll tell you honestly.
Surfaces we repair
- Conservatory frames
- Window frames & sills
- Coloured and woodgrain uPVC
- Doors & door panels
- White uPVC
