Leak Detection in Potters Bar

Potters Bar grew quickly in the 1930s, so most of the town is semis and detached houses of that period. They have suspended timber floors at the front and solid floors in later rear extensions. Many have had heating systems fitted and refitted, leaving pipework under floors and in screed. Cuffley and Northaw have large detached houses on big plots with long supply pipes and several bathrooms. Little Heath and the estates at Oakmere and Mount Grace are post-war, with heating pipes in concrete floors. Newer flats near the station use plastic pipework behind plasterboard. A 1930s house usually leaks at an old copper joint under a bathroom or kitchen.

We cover EN6, including Cuffley, Northaw, Little Heath, South Mimms, Oakmere and Mount Grace. Typical calls are a ceiling stain under a first-floor bathroom and a boiler losing pressure. Another is a soft or wet patch at the front of the house where the supply pipe comes in. Thermal imaging suits the timber floors, because warm pipes show through the boards. Tracer gas suits the solid floors in extensions and post-war houses. The acoustic ground microphone finds a supply pipe leak under a driveway or lawn in Cuffley, where the pipe can run a long way from the boundary stop tap.

Parking is simple on most roads, and in Cuffley and Northaw we can work from the drive. Near the station and the high street it is tighter and we carry the equipment in. We protect floors and furniture and open up only at the marked point. Your written report sets out the cause and the location, with photographs, thermal images and readings to back it up. It is prepared for a trace and access claim on your buildings insurance, with detection, access and repair listed as separate items so the claims handler can see each one.
