Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Nelson (BB9) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need cleaning and maintenance
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- You've never had it checked
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.
About Nelson and the BB9 area
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
Nelson is around 21 miles from Preston, and both are within our Lancashire coverage.
If you're just outside Nelson, we also cover Colne (2 miles), Burnley (3 miles), Accrington (8 miles).
What should you expect to pay in Nelson?
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?
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.
