Leak Detection From Diagnosis to Resolution
Investigation-Led Leak Detection & Repair
The Leak Hunter specialises in diagnosing leaks that are hidden, difficult to trace, or where the source of the problem is unclear. From concealed water leaks and central heating pressure loss to mains water supply issues, underground leaks, concrete floor leaks and confirmed gas leaks, every investigation begins with understanding what is actually happening before recommending the most appropriate solution.
Successful leak detection relies on more than specialist equipment alone. Water and gas can travel significant distances from the source of a fault, often appearing in a completely different location to where the problem originates. Every property, system and leak behaves differently, which is why investigations are tailored to the construction of the building, the affected pipework and the evidence available on site. Our approach combines practical experience with specialist diagnostic technology to accurately identify the cause of the problem while avoiding unnecessary disruption wherever possible.
Once the source of the leak has been identified, the next step is deciding how best to resolve the problem. The Leak Hunter can remain involved beyond the initial investigation, helping with repairs, controlled access, making-good works and insurance-related support where required. Customers remain fully in control of the process, but benefit from having continuity from diagnosis through to resolution and a clear understanding of the available options at each stage.

Common Leak Problems We Investigate
Many customers know something is wrong but aren’t sure what is causing it. These are some of the most common issues we investigate:
- Unexplained damp patches, staining or mould growth
- Boiler pressure that keeps dropping
- Unexpectedly high water bills
- A water meter that continues to move when no water is being used
- Wet floors, carpets or skirting boards
- Water appearing beneath floors or behind walls
- Water appearing in gardens, driveways or external areas
- Leaks hidden beneath concrete floors
- A gas supply that has been isolated following a confirmed gas leak
Our role is to identify the source of the problem, explain the findings and help you understand the most practical way forward.
Advanced Leak Detection Technologies We Use
We invest in state-of-the-art leak detection technologies to ensure the most accurate results with minimal disruption:
Pressure Testing
Monitor pressure changes in isolated sections of pipework to confirm leak locations.
Thermal Imaging Cameras
Detect temperature differences caused by leaks in walls, floors, and ceilings.
Acoustic Listening Devices
Identify the sound of escaping water or gas through pipes, even when buried underground or hidden.
Tracer Gas Detection
A safe, odourless gas is introduced into the pipework and traced to the point of escape, especially useful for very small or inaccessible leaks.
Moisture Mapping and Infrared Scanning
Used to determine the extent of water damage and identify areas of concern.
