We carry out leak investigation and inspection in Altrincham and across the WA14 area. Some leaks are obvious; many aren't.

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
Why it happens
Hidden water paths
Water can travel along bars, decks and linings before it shows.
More than one fault
Older lanterns often have two or three small failures.
Roof lanterns in Altrincham
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 Altrincham is roughly 8 miles — all part of the Greater Manchester area we cover.
We also cover nearby Sale (3 miles), Urmston (4 miles), Stretford (5 miles).
What should you expect to pay in Altrincham?
Guide price for leak investigation and inspection: £145–£295 ex VAT (£174–£354 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
