We carry out roof lantern replacement in Portishead and across the BS20 area. We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed.

Covering Portishead and nearby

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

We cover Portishead as part of Somerset, about 35 miles from Taunton.

Neighbouring places we cover include Nailsea (3 miles), Clevedon (5 miles), Bristol (8 miles).

What should you expect to pay in Portishead?

Guide price, supplied and fitted£1,995–£4,995 ex VAT£2,394–£5,994 inc VAT

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.
