The Technology and Equipment Behind Professional Leak Detection

Acoustic Listening Devices: Pinpointing the Sound of Escaping Water

The first line of investigation for pressurised pipework is often acoustic detection. Even the smallest leak under pressure creates a distinct high-frequency sound. Our engineers use ground microphones and amplified stethoscopes to listen for this signature noise through walls, floors, and along pipe runs.

This non-invasive method allows us to narrow down the leak's location without unnecessary damage. Crucially, we can often record these audio signatures. This provides tangible, objective data to include in our report, demonstrating to your insurer that we have corroborated evidence before any invasive work begins.

Thermal Imaging Cameras: Visualising Temperature Anomalies

Thermal imaging is a powerful tool for visualising the hidden effects of a leak. Escaping water changes the temperature of surrounding materials like plaster, screed, or timber. Our high-resolution thermal cameras detect these subtle differences, creating a detailed heat-map image of the affected area.

These thermal images are irrefutable visual evidence. They clearly show the extent of moisture migration and often the precise origin point. These photographs form a core part of our insurance report, providing a before-and-after visual ledger that justifies the exact area of trace and access proposed.

Tracer Gas Detection: The Definitive Test for Non-Pressurised Leaks

For leaks on drains, underfloor heating, or in pipes that can be isolated, tracer gas is the gold standard. We inject a safe, inert gas (a mix of hydrogen and nitrogen) into the pipework. This gas, which is lighter than air, escapes at the leak point and rises through the structure.

Our sensitive gas detectors then 'sniff' for its presence at the surface. This method is exceptionally precise and works where acoustic methods cannot. The successful detection of the tracer gas provides conclusive, scientific proof of a leak's location. This level of certainty is exactly what insurers look for to approve subsequent remedial work.

• Provides definitive, scientific proof of a leak's existence and location.
• Ideal for locating leaks in underfloor heating systems and non-pressurised waste pipes.
• Generates a clear procedural record for the insurance adjuster's review.

Moisture Mapping & Borescope Cameras: Quantifying the Damage

Once a leak area is identified, we must quantify the extent of the damage to support the scope of repairs. We use deep-probe moisture meters to map saturation levels in walls and floors, creating a detailed dampness profile. This data informs how much material needs to be removed.

For visual confirmation inside cavities or under floors, we use flexible borescope cameras. These allow us to inspect and record video evidence of the leak source and surrounding damage without initial large-scale exposure. This recorded footage is compelling evidence that minimises disputes over the necessary extent of work.

Our Reporting Protocol: The Key to Insurance Cost Recovery

The technology itself is only half the solution. Its value is realised through our meticulous reporting protocol, designed explicitly for insurance claims. We don't just provide a verbal summary; we compile a comprehensive, photographic and data-driven dossier.

This report includes timestamps, GPS data of our visit, annotated thermal images, moisture readings, acoustic logs or tracer gas detection results, and borescope footage. It clearly states the confirmed leak location, the recommended minimum trace and access points, and the diagnostic justification for each. This document becomes the foundation of your successful claim, satisfying the insurer's requirement for a justified, evidence-based course of action.

• Comprehensive digital report with timestamped and geo-tagged data.
• Annotated visual evidence (thermal images, borescope video stills).
• Clear, justified recommendation for the minimum necessary trace and access.
