Leak Detection in Harpenden

Harpenden is known for large detached and semi-detached houses from the Edwardian period and the 1930s, around the Common, East Common, Roundwood and Westfield. Most have been extended at the rear or into the loft. That adds bathrooms above living rooms and long runs of new pipework joined to old. Many kitchen extensions have underfloor heating in screed. Southdown and Batford have Victorian cottages and post-war houses with solid floors. Kinsbourne Green has cottages and barn conversions with private supply pipes. The joins between old and new plumbing are where leaks tend to start.

We cover AL5, including Southdown, Batford, Kinsbourne Green, East Common, Roundwood and Westfield. Typical calls are a ceiling stain under a new bathroom, an underfloor heating system that keeps needing topping up and a water meter turning with everything off. Thermal imaging shows underfloor heating loops through the screed and picks out the loop that is losing water. We isolate each loop at the manifold and pressure test it to confirm. Tracer gas finds pinhole leaks in pipework in walls, and the acoustic ground microphone locates a supply pipe leak under a long driveway.

Most Harpenden houses have a driveway, so parking is simple and we can work from the van. We protect floors, gravel and paving while we work. Most home surveys take between two and four hours, longer where there are several underfloor heating loops to test. You receive a written report with photographs, thermal images and readings that explains the cause and the location. It is prepared for a trace and access claim on your buildings insurance, with detection, access and repair kept apart so the insurer can see each one.
