Is it time for leak investigation and inspection?

  • The leak moves around or is intermittent
  • 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.

Covering Portsmouth 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.

What should you expect to pay in Portsmouth?

Guide price, per visit£145–£295 ex VAT£174–£354 inc VAT

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?

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.
