Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Wimbledon (SW19) 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
- You've never had it checked
- The lantern is under trees
Why it happens
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
About Wimbledon and the SW19 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.
Wimbledon is around 6 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Wimbledon, we also cover Morden (2 miles), Mitcham (2 miles), Putney (3 miles).
What should you expect to pay in Wimbledon?
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
