Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Morden (SM4) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Leaves or moss at the eaves
- You've never had it checked
- The lantern is under trees
Why it happens
Debris
Leaves and moss block drainage.
Unnoticed wear
Nobody looks at the roof until it leaks.
Roof lanterns in Morden
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.
We cover Morden as part of Greater London, about 7 miles from Westminster.
Neighbouring places we cover include Mitcham (1 mile), Wimbledon (2 miles), Carshalton (2 miles).
What should you expect to pay in Morden?
Most cleaning and maintenance jobs come in between £95 and £245 ex VAT (£114–£294 including 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.
