Do you need uPVC repair in Treowen?
uPVC is hard-wearing, but it does get damaged: ladders and building work leave scratches and chips, candles and cigarettes mark sills, and removed fittings leave holes.
You may need us if you’ve spotted any of these:
- Holes from removed fittings and alarms
- Chips and dents
- Damage during building work
- Scratches from ladders and furniture
Questions to ask before you book
- How long the guarantee is and what it covers
- What protection goes down before work starts
- When it can be used again
- Whether the colour is mixed to match
How we price uPVC repair
Repairs from £95. Quotes are free and the price is fixed. What we look at:
- Whether it’s a chip, crack, burn or wear
- The colour and finish to match
- The material
- Previous DIY repairs that have to come out
We do not add extras on the day. What we quote from your photos is what you pay, and if the damage turns out to be different, we discuss it before starting.
Send photos for a quote
Two or three clear photos are generally enough. It helps if you send:
- One sharp close-up of the damage
- What it’s made of, if you know
- Details of any past repairs
- One picture of the whole window, door or sill
No survey visit is needed: we price from pictures. Use the quote form, or ring 0345 017 0787 to talk it through.
DIY kit or professional repair?
A DIY attempt isn’t a disaster. We take the old repair out and do it properly, so it will not stop us repairing it. It does add a little time, so tell us about it when you send pictures.
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.
Repairing versus replacing in Treowen
A new window, door or sill costs far more, and new uPVC may not match the weathered frames around it. Repairing the damage keeps the original. Our uPVC repair starts from £95. No two jobs are quite the same, so we price each one individually. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.
