Can I fix it myself?
DIY kits are sold for most surfaces, and they can tidy up a tiny mark. Where they fall down is colour and preparation: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
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.
When to call us in Sandon
uPVC is tough but not indestructible: ladders, tools and building work scratch and chip it, candles and cigarettes mark sills, and removed fittings leave holes.
Look out for these signs:
- Burns on sills
- Holes from removed fittings and alarms
- Damage during building work
- Scratches from ladders and furniture

For landlords and businesses
Hotels, guest houses and holiday lets need rooms back in use quickly, so most of our work is done in a single visit. We’ll fit around changeovers where we can.
We work for landlords, letting agents and housing providers in Sandon as well as householders. Repairing between tenancies keeps void periods short, and it typically costs far less than a refit.
The process
On the day, we arrive at the time we’ve agreed, cover the area with dust sheets and masking, and set to work. The job generally takes a few hours. We tidy up before we leave and tell you when it’s ready to use.
- We clean the frame or panel.
- Next we fill the damage.
- We sand the repair smooth.
- The finish is colour-matched, woodgrain included.
- Finally we blend it into the rest of the frame.
How to prepare
- Tell us about any previous repairs or coatings
- Point us to the nearest place to park
- Have a window or extractor fan available

Repair or replace: which is better?
A new window, door or sill is a much bigger job, and new uPVC may not match the weathered frames around it. A repair leaves the unit in place. Our uPVC repair starts from £95.

FAQs for Sandon
Can you repair something that is been repaired before?
Most of the time. Let us know what was used before and we’ll plan for it.
Can you do more than one item on the same visit?
Yes, and it’s often cheaper. Send pictures of everything together and we will quote them together.
Can tenants book a repair?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
What do you need from me?
Photos of the damage, a picture of the entire window, door or sill and your postcode. After that, we just agree a date.
What areas do you cover?
We cover the whole UK, including Sandon and the rest of Hertfordshire. Just include your postcode and we will confirm dates.
Will it make a mess?
Dust sheets and masking go down before we start, and we clean up when we’ve finished.
Is repairing better than replacing?
Usually, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. We will tell you honestly if replacement makes more sense.
Are you a vetted contractor?
We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.
