Signs you need leak investigation and inspection

  • Previous repairs haven't stopped the leak
  • 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.

Covering Northampton and nearby

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

Neighbouring places we cover include Wellingborough (9 miles), Daventry (12 miles), Rushden (12 miles).

Guide prices for leak investigation and inspection in Northampton

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?

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.
