About Whitstable and the CT5 area
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Whitstable is around 23 miles from Maidstone, and both are within our Kent coverage.
Neighbouring places we cover include Herne Bay (5 miles), Canterbury (6 miles), Faversham (7 miles).
Guide prices for roof lantern replacement in Whitstable
Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
