In Bolton, as everywhere, some leaks are obvious; many aren't. Send photos and we'll tell you what we think has failed.

What you might be seeing

  • Previous repairs haven't stopped the leak
  • The leak moves around or is intermittent
  • You need a written report for a landlord, insurer or builder

Common causes we find

More than one fault

Older lanterns often have two or three small failures.

Not the lantern

Sometimes the source is the flat roof, a parapet, a gutter or a wall above.

Covering Bolton and nearby

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.

Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.

From Manchester to Bolton is roughly 11 miles — all part of the Greater Manchester area we cover.

Close by, we also cover Farnworth (3 miles), Westhoughton (4 miles), Radcliffe (5 miles).

Guide prices for leak investigation and inspection in Bolton

Guide price, per visit£145–£295 ex VAT£174–£354 inc VAT

Most leak investigation and inspection jobs come in between £145 and £295 ex VAT (£174–£354 including 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.
