We carry out cleaning and maintenance in Sevenoaks and across the TN13 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?
- Leaves or moss at the eaves
- You've never had it checked
- The lantern is under trees
What usually causes it?
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
About Sevenoaks and the TN13 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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Sevenoaks as part of Kent, about 14 miles from Maidstone.
If you're just outside Sevenoaks, we also cover Tonbridge (6 miles), Swanley (9 miles), Tunbridge Wells (10 miles).
What should you expect to pay in Sevenoaks?
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
