About Streatham and the SW16 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.

Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.

Streatham is around 5 miles from Westminster, and both are within our Greater London coverage.

Neighbouring places we cover include Mitcham (2 miles), Brixton (3 miles), Wimbledon (3 miles).

How much should it cost?

Guide price, per visit£95–£245 ex VAT£114–£294 inc VAT

Typical range: £95–£245 ex VAT, which is £114–£294 with VAT, per visit. 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.
