Questions from Monkswood
Can pets and children be at home?
On the day, the room should be kept clear of pets and children, so the repair isn’t disturbed while it cures.
How do I book?
Some pictures, your postcode and how to reach you. On the day, access to the room.
Is it worth repairing rather than replacing?
Usually, when the rest is in good condition. A repair avoids removal and making good. If replacing would be better, we’ll say so.
Do you work for landlords and businesses?
Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses.
Can a burnt window sill be fixed?
Yes. The burn is filled and refinished to match.
Can you match woodgrain uPVC?
Yes. Colour and grain are matched by hand.
Do I have to be there?
Yes. We need access to the room while we work, at a time that suits you.
Will there be a smell?
A little, depending on the job. Ventilation keeps it to a minimum.
What uPVC repair costs
Prices start from £95. We price every job individually. What matters most is:
- How hard the colour is to match
- Any earlier repairs that need removing first
- How many areas need work
- The type of damage
No two jobs are quite the same, so each one is priced on its own. The size and type of damage, the material and access all make a difference, and doing several things on one visit costs less than separate visits.
How to get a fixed quote
Almost every job we do is priced from pictures. This is what to send:
- Details of any past repairs
- One picture of the whole window, door or sill
- Any details about the material
- Good light, ideally daylight, without flash glare
Most customers in Monkswood get their price from pictures. Add a line about what happened and your postcode, and we will reply with a fixed quote and the earliest dates we have.
Landlords, agents and businesses in Monkswood
We regularly price jobs from inventory or check-out pictures. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.
Rented homes see more wear and tear, and replacing things at every changeover adds up. A repair between tenancies is a cheaper way to keep the property in good order.
DIY kit or professional repair?
DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
A DIY attempt is not a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. It does add a little time, so tell us about it when you send pictures.
How it works
Nothing needs to be moved out of the room beforehand. Everything we use comes in the van with us, put protection down and get going once we’ve agreed what we are doing. It typically takes a few hours, and you can get on with other things while we’re there.
- First the frame or panel is cleaned.
- We fill scratches, chips and holes.
- We smooth the repair.
- We colour-match the finish, including woodgrain effects.
- The repair is blended into the surface around it.
Before we arrive
- Make sure the area is dry
- Move bottles, mats and clutter away from the area
- Tell us about any previous repairs or coatings

Should you replace it?
A new window, door or sill is a much bigger job, and it may not match the rest after years of weathering. Repairing the damage keeps the original. Prices start from £95. We charge the same wherever you are, with no extra for Monkswood. The job itself decides the price: how much damage, what it’s made of and how many items.
