We carry out cleaning and maintenance in New Malden and across the KT3 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.

Signs you need cleaning and maintenance
- Dirty glass or green algae on the frame
- You've never had it checked
- The lantern is under trees
Common causes we find
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
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.

What should you expect to pay in New Malden?
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?
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.
