We carry out leak investigation and inspection in Lincoln and across the LN2 area. Some leaks are obvious; many aren't.

Is it time for leak investigation and inspection?
- 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
What usually causes it?
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.
About Lincoln and the LN2 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Neighbouring places we cover include Gainsborough (14 miles), Newark-on-Trent (16 miles), Retford (18 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?
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.
