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 Barrow-in-Furness (LA14) and we'll tell you which it is — with the price agreed in writing before any work.

Why it happens
Age

Structural damage
Impact or movement distorts the frame.
Roof lanterns in Barrow-in-Furness
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.

Guide prices for roof lantern replacement in Barrow-in-Furness
Typical range: £1,995–£4,995 ex VAT, which is £2,394–£5,994 with 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?
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.
