What uPVC repair costs
Prices start from £95. A fixed quote means you know the cost before you book. We take into account:
- Access to the area
- Doing more than one item at once
- The colour and finish to match
- The type of damage
We charge the same wherever you are, with no extra for Underwood. The job itself decides the price: the material, the amount of damage and how many items.
Getting a price from photos
Most quotes are done from photos alone. To help us price it:
- Details of any past repairs
- A picture taken from further back
- Where you are, by postcode
- A coin beside the damage so we can judge size
Getting a quote takes a couple of minutes: take one close-up and one wider shot of the window, door or sill, include your postcode and send them to us. You will get a fixed quote, not an estimate.
Honest limits
A repair is not right for every job, for example:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square

Landlords, agents and businesses in Underwood
Rented homes see more wear and tear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
If you manage property in Underwood, we will quote for several properties at once. Just send pictures for each address and we will come back with a combined price.
Repair or replace: which is better?
Replacing the frame or sill costs far more, and new uPVC may not match the weathered frames around it. A repair leaves the unit in place. Prices start from £95. A few things move the price: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.

What we’re called out for in Underwood
uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes burn sills, and old fittings leave holes.
Keep an eye out for these signs:
- Burns on sills
- Holes from removed fittings and alarms
- Damage during building work
- Chips and dents
Before booking anyone
- What happens if the damage is worse than the photos show
- How long it needs to cure
- How the colour is matched
- A fixed quote, and whether VAT is included
Can I fix it myself?
What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.
It’s natural to want to try a repair yourself. The trouble is that kit repairs often look fine at first and then fail, and then the old filler has to be removed first.

Underwood questions
Is it OK to have pets in the house?
Just keep them out of the work area. We will let you know when it’s safe to use again.
Can I get a quote without a visit?
Nearly always. We only ask to see it in person if the photos cannot show what we need.
Can landlords book you?
Yes. We work for landlords, agents, builders and businesses as well as homeowners in Underwood.
Is the work guaranteed?
All our work carries a one-year guarantee. Ask us what it covers when you get your quote.
Is it worth repairing rather than replacing?
Usually, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. We will tell you honestly if replacement makes more sense.
Are you a vetted contractor?
We’re accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
Will it make a mess?
Very little mess: we sheet and mask everything nearby, and we leave the room clean.
Will there be a smell?
Some materials have a smell while they’re applied, so we ventilate the room. It clears as the materials cure.
