Specialist Leak Detection Engineers
Water Leak Detection Specialists Across London & Southern England

- Evidence-led, non-destructive methods
Evidence-Led Investigation
Methods Selected For The Property And Symptoms
No single method is suitable for every suspected leak. Engineers assess the symptoms, pipework and property construction before selecting the techniques most likely to provide useful evidence.
Thermal Imaging
Infrared scanning helps identify temperature patterns linked to concealed water movement.
Tracer Gas
Safe trace gas can confirm leaks in pipework where visual access is limited.
Acoustic Detection
Sensitive listening equipment tracks leak noise through pipes, floors and ground.
Moisture Mapping
Moisture readings map water spread and separate leak evidence from surface staining.

“Pro leak detection came out to review leak in bathroom. They were immediately scoping the root cause and found the issue very quickly. I was surprised by their honesty and professionalism to get the job done rather than others who may have tried to stretch it out to increase the bill. Well done to the team, can’t recommend them enough.”
