What you might be seeing

  • 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

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 Seaham and the SR7 area

Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.

We cover Seaham as part of County Durham, about 10 miles from Durham.

What should you expect to pay in Seaham?

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

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.
