Leak Detection in Croydon

Croydon town centre has many office buildings converted into flats, with new plastic pipework behind plasterboard and shared risers serving dozens of homes. Addiscombe, Selhurst and Broad Green are Victorian terraces with suspended floors. Shirley, Selsdon, Sanderstead and Purley Oaks were built mostly in the 1930s with semis and detached houses on solid ground floors and heating pipes in the screed. South Croydon and Park Hill have larger Edwardian houses. New Addington is post-war. The hills on the southern side sit on chalk, so a leaking supply pipe can drain away without a wet patch showing at the surface for a long time.

We cover CR0 and CR2, including Addiscombe, Shirley, Selhurst, Waddon, New Addington, South Croydon, Sanderstead, Selsdon and Purley Oaks. The common calls are a water bill that has jumped, a meter turning with everything off, a boiler losing pressure, and water appearing in a flat from the one above. For supply pipes we listen along the route with the acoustic ground microphone on paving and tarmac and confirm with tracer gas. Heating leaks in screed are found with a pressure test, tracer gas and the thermal camera. In converted blocks we test each source and map moisture to prove the route.

Parking in central Croydon is controlled, so we take the kit in on a trolley and use visitor permits where the building provides them. The suburban roads in Shirley, Selsdon and Sanderstead usually have space on the driveway. We mark the leak position clearly so any digging is a small hole, not a trench. The written report has photographs, readings and thermal images and is prepared for a trace and access claim on your buildings insurance.
