In Dartford, as everywhere, commercial lanterns and atrium rooflights fail in the same ways as domestic ones, but access, safety and disruption matter more. Send photos and we'll tell you what we think has failed.
What you might be seeing
- Leaks into trading or office areas
- Multiple lanterns on one roof needing a programme
- Managed buildings with planned maintenance needs
Why it happens
Access
Roof access, edge protection and permits all affect the plan.
Deferred maintenance
Leaks appear when maintenance has slipped.
Covering Dartford and nearby
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.
From Maidstone to Dartford is roughly 18 miles — all part of the Kent area we cover.
Neighbouring places we cover include Bexley (3 miles), Swanley (4 miles), Welling (5 miles).
How much should it cost?
Most commercial roof lantern repairs jobs come in between £495 and £2,995 ex VAT (£594–£3,594 including 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.
