We carry out leak investigation and inspection in Sandhurst and across the GU47 area. Some leaks are obvious; many aren't.

Is it time for 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 Sandhurst and the GU47 area
Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.
From Reading to Sandhurst is roughly 11 miles — all part of the Berkshire area we cover.
Close by, we also cover Crowthorne (2 miles), Yateley (2 miles), Camberley (2 miles).
How much should it cost?
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.
