Thornton Consulting

Thornton Consulting is the UK's leading specialist in leak detection and waterproofing investigations, delivering services for commercial and large residential buildings since 1986.

With 60+ years of combined management experience and a qualified team of leak detection engineers and consultants, we provide unparalleled expertise in locating and analysing leaks across all types of buildings.

Our advanced testing techniques include electronic leak detection using both "wet" (low voltage) and "holiday" (pinhole) dry methods, supported by differential pressure testing for non-conductive deck applications. As pioneers of Leaktector, we revolutionised electronic testing for flat roof waterproofing membranes. We also specialise in waterproof integrity testing for newly installed systems, roof condition surveys, leak investigations, and cost-effective planned maintenance programmes.

Serving clients in London, Manchester, Bristol, and the South East, our field teams deliver prompt, professional services to residential blocks, car parks, shopping centres and commercial properties.
