We carry out leak investigation and inspection in Christchurch and across the BH23 area. Some leaks are obvious; many aren't.

What you might be seeing
- The leak moves around or is intermittent
- You're not sure if it's a leak or condensation
- You need a written report for a landlord, insurer or builder
Common causes we find
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 Christchurch and the BH23 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Christchurch as part of Dorset, about 4 miles from Bournemouth.
Close by, we also cover Bournemouth (4 miles), New Milton (5 miles), Poole (9 miles).
Guide prices for leak investigation and inspection in Christchurch
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.
