Tracer Gas Leak Detection

Tracer gas is a food-grade mixture of hydrogen and nitrogen that is completely safe for use in all types of pipework, including drinking water supply pipes. It is non-flammable, non-toxic, non-corrosive, and environmentally harmless. It has been approved and tested for use in drains, water mains, grey water waste systems, and fire suppression pipework.

No. That is the key advantage of tracer gas detection. The entire process is completely non-invasive — no digging, no lifting of tiles or floorboards, and no damage to your walls or ceilings. The gas rises naturally through the ground or building materials and is detected at the surface using sensitive electronic equipment.

In most cases, a tracer gas survey can be completed within a few hours. The duration depends on the size of the property, the number of pipe runs to be tested, and the complexity of the leak. Our specialist will give you a clearer timeframe once they have assessed your property.

Yes. Following the survey, we provide a detailed written report confirming the location of the leak and the findings of the test. This report is fully accepted by UK insurers and can be submitted as part of an escape of water insurance claim to authorise repair and reinstatement works.

Yes — this is one of tracer gas detection's greatest strengths. The gas molecules are small enough to permeate through concrete, tarmac, paving slabs, and most other building materials. This makes it the most effective method for detecting leaks in pipes buried beneath solid floors or external hard landscaping.

In many cases, the cost of trace and access — which includes leak detection — is covered under a standard buildings insurance policy. As your loss assessor, Vanguardo will review your policy wording and ensure all eligible costs, including the tracer gas survey, are claimed back from your insurer on your behalf.
