Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos from Dartford (DA1) and we'll tell you which it is — with the price agreed in writing before any work.

Paint failure
Once the paint film breaks, water gets into the end grain and joints.
No maintenance
Timber needs redecorating on a cycle; skipped cycles turn small repairs into big ones.
About Dartford and the DA1 area
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.
Dartford is around 18 miles from Maidstone, and both are within our Kent coverage.

What should you expect to pay in Dartford?
Guide price for timber roof lantern repairs: £395–£1,995 ex VAT (£474–£2,394 inc VAT), per lantern. 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.
