We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. Send photos from Sandown (PO36) and we'll tell you which it is — with the price agreed in writing before any work.

About Sandown and the PO36 area
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).
Guide prices for roof lantern replacement in Sandown
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc VAT), supplied and fitted. 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
