uPVC Repair in Letchworth
Problem with your window, door or sill in Letchworth? We repair it in place, mix the colour on the day and guarantee the work for a year.
- Repairs from £95
- Chips and dents
- Holes from removed fittings and alarms

Should I try a DIY kit first?
The difference between a kit and a professional repair is mostly in the preparation and colour. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
If you do try a kit, read the instructions carefully, and do not use it until it has fully cured. If it doesn’t work out, we can still repair it properly.
uPVC repair at your home in Letchworth
Builders and developers use us for snagging repairs too. We fill and refinish the damage to match the frame, including woodgrain finishes. If you’re dealing with burns on sills and chips and dents, we can help, whatever the material.
We stand behind the work with a one-year guarantee, so you are covered after the visit. Clean with warm soapy water and a soft cloth. Don’t use solvents or scourers.

Advice
Repairing versus replacing in Letchworth
Replacing the frame or sill is a much bigger job, and new uPVC may not match the weathered frames around it. Repairing the damage keeps the original. Repairs from £95, with every job priced individually. We do not add extras on the day. What we quote from your pictures is what you pay, and if the damage turns out to be different, we discuss it before starting.

How we price uPVC repair
Prices start from £95. Each job gets its own fixed price. This is what makes a difference:
- What the surface is made of
- How easy the damage is to reach
- How hard the colour is to match
- 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 combining jobs on one visit brings the cost down.
Send photos for a quote
It only takes a minute to photograph the damage, and it saves a visit. Please include:
- A picture taken from further back
- A coin or ruler next to the damage for scale
- Daylight if possible, and no flash reflection
- Any earlier repairs or coatings
We price from pictures so you don’t have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and you will get a fixed figure back.
