In Northwich, 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
- You're not sure if it's a leak or condensation
- You need a written report for a landlord, insurer or builder
What usually causes it?
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.
About Northwich and the CW9 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.
From Chester to Northwich is roughly 16 miles — all part of the Cheshire area we cover.
Close by, we also cover Winsford (5 miles), Warrington (10 miles), Runcorn (10 miles).
Guide prices for leak investigation and inspection in Northwich
Typical range: £145–£295 ex VAT, which is £174–£354 with 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.
