Common questions in Whetstone
What does uPVC repair cost?
Prices start from £95. The exact price depends on the damage, so we quote from photos. You know the full cost before anything is booked.
Is it OK to have pets in the house?
Keep pets and children away from the work area on the day.
Is there a guarantee?
Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.
Will it make a mess?
Dust sheets and masking go down before we start, and we clean up when we have finished.
What if the damage is worse than the photos show?
Your quote covers the damage in the photos. If there’s more, we will tell you before starting.
What happens after I send pictures?
We review the pictures and send a fixed quote with dates.
Do the materials smell?
Expect a mild smell while we are working.
Do you repair coloured uPVC?
Yes. We recreate the colour and grain by hand.
Should I try a DIY kit first?
Kits are cheap and easy to find, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is usually the cheaper route.
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: they come in a handful of shades, and if the surface is not prepared the repair won’t last.
What uPVC repair costs
Repairs from £95. You won’t pay by the hour. The price is based on:
- What the surface is made of
- Whether it’s a chip, crack, burn or wear
- Unusual colours or finishes
- Whether we combine several jobs
It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Photos let us give you a fixed figure.
Send pictures for a quote
Two or three clear pictures are typically enough. Try to include:
- Any details about the material
- Your postcode, so we can check dates
- A close-up of the damage, in focus
- Something in shot to show the size
There’s no need for us to visit first. Nearly every job can be priced from photos: we need a close-up, a wider picture and your postcode, and we’ll reply with a fixed quote.
