We carry out cleaning and maintenance in Blackheath and across the SE3 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.

Roof lanterns in Blackheath

Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.

London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

From Westminster to Blackheath is roughly 7 miles — all part of the Greater London area we cover.

We also cover nearby Greenwich (1 mile), Catford (2 miles), Eltham (2 miles).

Guide prices for cleaning and maintenance in Blackheath

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

Guide price for cleaning and maintenance: £95–£245 ex VAT (£114–£294 inc 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.
