In East Grinstead, 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're not sure if it's a leak or condensation
Common causes we find
Hidden water paths
Water can travel along bars, decks and linings before it shows.
Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
About East Grinstead and the RH19 area
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
East Grinstead is around 39 miles from Chichester, and both are within our West Sussex coverage.
Neighbouring places we cover include Horley (7 miles), Crawley (8 miles), Crowborough (9 miles).
What should you expect to pay in East Grinstead?
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?
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.
