We carry out cleaning and maintenance in Dover and across the CT16 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.

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
Debris
Leaves and moss block drainage.
Algae and dirt
Hold moisture against seals and spoil the view.
Roof lanterns in Dover
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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Dover is around 36 miles from Maidstone, and both are within our Kent coverage.
If you're just outside Dover, we also cover Folkestone (7 miles), Deal (8 miles), Canterbury (15 miles).
Guide prices for cleaning and maintenance in Dover
Typical range: £95–£245 ex VAT, which is £114–£294 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.
