Your questions about uPVC repair in Harwell
What areas do you cover?
We work UK-wide. Prices don’t change with location.
Can a burnt window sill be fixed?
Yes. We fill and refinish the burnt area to match.
Can tenants book a repair?
Yes, though it’s best to check with your landlord first. Many landlords are happy for a repair to be arranged before the end of a tenancy.
Does someone need to be in?
Someone needs to let us in and show us the job. You don’t need to watch us work.
Do you charge for travel?
We do not add a call-out fee. The fixed quote covers the visit and the work.
Can I add another job to the visit?
Yes. Doing several items on one visit generally costs less than separate visits. Include pictures of each item.
Can you quote from photos?
Nearly always. If photos do not show enough, we’ll ask for another angle.
Can you redo someone else’s repair?
Most of the time. Tell us what was done before and we’ll plan for it.

DIY kit or professional repair?
We understand the appeal of fixing it yourself. The trouble is that kit repairs frequently look fine at first and then fail, and the old filler has to come out before a proper repair.
If you’re set on a kit, follow its instructions closely and work on a clean, dry surface, and give it the full curing time. If it does not work out, we can still repair it properly.
Common problems we fix in Harwell
uPVC is hard-wearing, but it does get damaged: ladders and building work leave scratches and chips, candles and cigarettes burn sills, and old fittings leave holes.
The things clients normally mention when they call are:
- Scratches from ladders and furniture
- Chips and dents
- Burns on sills
- Holes from removed fittings and alarms
What your quote should include
- How soon you can use it again
- What aftercare is recommended
- What the guarantee covers, and for how long
- Whether the colour is mixed to match
Work for landlords and builders
We also carry out snagging repairs for builders and developers, fixing chips and scratches before handover. We are CHAS, Constructionline and SafeContractor accredited.
We regularly price jobs from inventory or check-out photos. That means we can quote before you even visit the property, and we liaise with tenants about access if you’d like us to.
How the visit works
We agree an arrival time beforehand, so you’re not left guessing. Once we’re there, the work takes a few hours for most jobs. The room is left tidy.
- We clean the frame or panel.
- We fill scratches, chips and holes.
- We sand the repair smooth.
- We match the colour, including woodgrain finishes.
- We blend the repair into the surrounding surface.
Before we arrive
- Let us know which floor the room is on
- Have somewhere for us to park nearby if possible
- Let us know if it has been repaired before
Ask for a price
A quote takes minutes to ask for: 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.

How we price uPVC repair
Prices start from £95. There is no charge for travel to Harwell. The price comes down to:
- Doing more than one item at once
- Any earlier repairs that need removing first
- The size and number of damaged areas
- What the surface is made of
We charge the same wherever you are, so there’s no premium for Harwell. The job itself decides the price: how much damage, what it’s made of and how many items.
Quotes from your pictures
Photographing the damage takes a minute, and it saves a visit. Please include:
- Daylight if possible, and no flash reflection
- Details of any past repairs
- A picture taken from further back
- Your postcode, so we can check dates
For most jobs, photos are all we need to give you a price. Add a line about what happened and your postcode, and we will reply with a fixed quote and the earliest dates we have.
Repair or replace in Harwell?
A new window, door or sill costs far more, and it may not match the rest after years of weathering. A repair keeps the original. Prices start from £95. The price depends on the type and amount of damage, what it’s made of and how many items we do on one visit. You get a fixed price from your photos, so there are no surprises on the day.
