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

Signs you need leak investigation and inspection
- 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.
Covering Grimsby and nearby
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Grimsby is around 30 miles from Lincoln, and both are within our Lincolnshire coverage.
If you're just outside Grimsby, we also cover Cleethorpes (2 miles), Hull (16 miles), Scunthorpe (24 miles).
How much should it cost?
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
