In Crawley, 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
Why it happens
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.
Roof lanterns in Crawley
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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Crawley is around 32 miles from Chichester, and both are within our West Sussex coverage.
We also cover nearby Horley (4 miles), Horsham (7 miles), East Grinstead (8 miles).
What should you expect to pay in Crawley?
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.
