- The leak moves around or is intermittent
- You're not sure if it's a leak or condensation
Why it happens
Hidden water paths
Water can travel along bars, decks and linings before it shows.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
About Morden and the SM4 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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 Morden is roughly 7 miles — all part of the Greater London area we cover.

Guide prices for leak investigation and inspection in Morden
Typical range: £145–£295 ex VAT, which is £174–£354 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?
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.
