Why Fire Leak
Detection Matters

Undetected losses can leave your property under-protected in an emergency. Early detection:

Our Fire Leak Detection Process

We use targeted, non-destructive testing to pinpoint faults quickly and minimise disruption:

1. Pressure &
isolation testing

— narrow down leak zones

2. Acoustic listening

— identify escape noise in buried lines

3. Line location & mapping

— trace pipe runs without excavation

4. Dye testing (as applicable)

— confirm ingress points

5. Sectional verification

— confirm exact repair point before works

Fire Leak Detection FAQs

What parts of a fire system can leak?

Fire mains, hydrant branches, sprinkler lines, hose reel feeds, valves and joints — especially on older pipework or where ground movement occurs.

Can you find leaks without digging up the whole line?

Yes. We combine isolation, acoustic listening and line location to target a small repair area and avoid unnecessary excavation.

Do you provide reports for facility managers and insurers?

Yes — photos, findings and recommended next steps to support compliance and maintenance plans.

Do you offer after-hours testing?

Yes. We can schedule around trading hours to minimise disruption.

How much does fire leak detection cost?

Whilst costs can vary depending on the complexity, location of the leak and size of the network, we’ll always provide a clear plan of action once we’ve inspected the site. Modern leak detection methods are non-invasive, utilising technologies like thermal imaging and acoustic sensors, which can also save on repair costs.
