We carry out leak investigation and inspection in Barnsley and across the S70 area. Some leaks are obvious; many aren't.

Signs you need leak investigation and inspection
- Previous repairs haven't stopped the leak
- 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.

Freeze-thaw cycles open up tired sealant and gaskets faster than mild weather does. A spring check after a hard winter catches most problems before they leak.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
Barnsley is around 12 miles from Sheffield, and both are within our South Yorkshire coverage.
Neighbouring places we cover include Wakefield (9 miles), Rotherham (10 miles), Ossett (10 miles).
How much should it cost?
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.
