We carry out leak investigation and inspection in Corby and across the NN17 area. Some leaks are obvious; many aren't.
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 Corby and nearby
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 Northampton to Corby is roughly 19 miles — all part of the Northamptonshire area we cover.
If you're just outside Corby, we also cover Uppingham (6 miles), Kettering (7 miles), Market Harborough (10 miles).
Guide prices for leak investigation and inspection in Corby
Typical range: £145–£295 ex VAT, which is £174–£354 with 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.
