Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Stratford (E15) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for cleaning and maintenance?
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- The lantern is under trees
What usually causes it?
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
Roof lanterns in Stratford
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.

Guide prices for cleaning and maintenance in Stratford
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?
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.
