About our uPVC repair in Blackwater
The damage is filled and refinished to match the frame, woodgrain finishes included. Builders and developers use us for snagging repairs too. Common call-outs are for scratches from ladders and furniture and burns on sills, on doors & door panels, conservatory frames and white uPVC.
The work is covered for a year after we finish. Just call us if there’s a problem and we’ll sort it. Warm soapy water and a soft cloth are all it needs. Don’t use solvents or scourers.

Your questions about uPVC repair in Blackwater
Do you cover Blackwater?
We do. We send a technician to Blackwater for every job, with no extra charge for travel.
Is a repair better than a new one?
Typically, when the rest is in good condition. A repair avoids removal and making good. We will tell you honestly if replacement makes more sense.
Does someone need to be in?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
Do you cover the whole of Cornwall?
Everywhere in the UK, Blackwater included. There is no extra charge for travel.
Can tenants book a repair?
Yes. Check with your landlord; we can send the quote to them too.
Do you work for landlords and businesses?
We do, regularly. We quote for multiple addresses and fit around tenancy changeovers.
Are there extra charges for Blackwater?
Travel is included in the price, with the same prices everywhere we work.
Is there a guarantee?
Yes: twelve months. If there is a problem with the work in that time, we come back and put it right.
Can I fix it myself?
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.
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
Common problems we fix in Blackwater
uPVC is hard-wearing, but it does get damaged: ladders, tools and building work scratch and chip it, candles and cigarettes mark sills, and old fittings leave holes.

- Chips and dents
- Scratches from ladders and furniture
- Burns on sills
- Holes from removed fittings and alarms

What affects the price in Blackwater
Repairs from £95. Prices are worked out job by job. What matters most is:
- What kind of damage it is
- The material and finish
- Any earlier repairs that need removing first
- How many items we do on one visit
Our prices are the same across the UK, with no extra for Blackwater. 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, a few simple things make all the difference:
- The material, if you know it
- A photo taken from further back
- A clear, close picture of the problem area
- Your postcode, so we can check dates
No survey visit is needed: we price from pictures. Use the quote form, or ring 0345 017 0787 to talk it through, and we will come back with a fixed figure.
Repair or replace: which is better?
A new window, door or sill costs far more, and new uPVC may not match the weathered frames around it. A repair leaves the unit in place. Repairs from £95, with every job priced individually. There are no surprise extras on the day. The price we quote from your photos is the price you pay, unless the damage turns out to be different, in which case we talk to you first.
