We carry out uPVC roof lantern repairs in Sandown and across the PO36 area. Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings.

What you might be seeing
- Yellowed or brittle end caps
- Cracked cappings or ridge covers
- Rattling or whistling in wind
Common causes we find
UV ageing
uPVC components become brittle and crack after years of sun.
Clip failure
Clip-on cappings can lose their grip and lift.
Roof lanterns in Sandown
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Sandown by arrangement: island work is planned around ferry access, and any travel or access costs are set out in your written quote before you commit.
We also cover nearby Ryde (5 miles), Newport, Isle of Wight (7 miles), Cowes (10 miles).
How much should it cost?
Typical range: £175–£595 ex VAT, which is £210–£714 with VAT, per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
