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

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.

Covering Chesterfield and nearby

Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.

From Derby to Chesterfield is roughly 23 miles — all part of the Derbyshire area we cover.

We also cover nearby Staveley (3 miles), Dronfield (4 miles), Sheffield (9 miles).

How much should it cost?

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?

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.
