1. Tracer Gas Leak Detection

One of the most effective tools for finding hidden leaks in water pipes. This method uses a safe, non-toxic hydrogen/nitrogen gas mix that is introduced into the pipework. The gas escapes even through the smallest leak point and is detected at the surface using a sensitive gas detector — ideal for underground, underfloor, and central heating leaks.

2. Thermal Imaging Cameras

Our high-resolution thermal imaging cameras detect temperature changes behind walls, ceilings, and floors — helping us locate hot and cold water pipe leaks, central heating faults, and underfloor heating issues without breaking surfaces.

3. Borescope Camera Inspection

When internal access is needed, our borescope cameras provide a clear view inside concealed areas like cavities, ceilings, and voids. This allows us to inspect behind tiles, floorboards, and drywall with minimal disruption.

4. CCTV Drain Camera Surveys

For drain and waste pipe leaks, we use advanced drain CCTV cameras that travel through your pipework and deliver high-definition footage. This allows us to spot cracks, joint failures, blockages, or root intrusions — often the cause of slow leaks or foul smells.

5. Pressure Testing

To confirm pipework integrity, we use pressure testing equipment to detect pressure drops within your water or heating system. This helps identify whether a leak is present even if water is not visibly escaping.

6. Dye Testing

We use coloured dye in water systems to visually confirm the source of moisture or water staining — especially useful for bathroom leaks, ceiling damp, or suspected shower tray failures.

7. Smoke Generator Testing

Smoke testing is a reliable method for detecting hidden leaks in drainage systems. By introducing non-toxic, visible smoke into the pipework, we can quickly identify cracks, gaps, or faulty connections as the smoke escapes from the defect points. This method is especially effective for tracing odour issues, locating breaches in soil pipes, and detecting leaks in flat roofs or underground systems.
