Acoustic Leak Detection in Northern Ireland

If you suspect a hidden leak under a floor, behind a wall, or in an underground pipe run, acoustic leak detection can help narrow down the likely location before anyone starts digging or lifting finishes.

We use specialist listening equipment as part of a structured leak investigation to reduce guesswork and focus any access and repair work where it’s most needed.

Acoustic Leak Detection in Northern Ireland

Signs a hidden leak may be present

People usually contact us when they notice:

  • Unexplained damp patches, staining, or recurring mould
  • Wet ground, pooling water, or soft spots outside
  • A pressure drop in the heating system or boiler needing frequent topping up
  • The sound of running water when nothing is on
  • Ongoing moisture with no clear source

If you’re not sure it’s a leak, tell us what you’re seeing and we’ll advise the best next step.

What acoustic leak detection actually does

Leaks under pressure often create vibrations and sound. These signals can travel through pipework and surrounding materials.

Acoustic equipment helps us listen for those patterns and compare readings at different points along a suspected pipe route. In the right conditions, this can help narrow the search area and guide targeted access.

In the right conditions, those temperature patterns can indicate areas affected by:

It’s not a magic “X marks the spot”. Accuracy depends on factors like pipe material, depth, water pressure, background noise, and ground conditions. Where needed, we use other checks to confirm the source.

When acoustic detection is useful (and when it isn’t)

Often useful for:

  • Suspected underground leaks (driveways, gardens, service runs)
  • Leaks under concrete floors where access needs to be planned carefully
  • Longer pipe runs where the leak location isn’t obvious
  • Situations where you want to avoid unnecessary excavation or opening-up

Not always the best first step for

It may be less helpful on its own when:

  • Very low-pressure or intermittent leaks
  • Areas with heavy background noise or vibration
  • Certain plastic pipework setups where sound transmission is reduced

If acoustic testing isn’t the right fit, we’ll explain why and what we’d use instead.

How our acoustic leak detection process works

We keep the approach simple and clear, so you know what's happening.

  1. 1

    Symptom review

    You explain what you’ve noticed, where it’s happening, and any recent changes (repairs, new flooring, heating issues).

  2. 2

    Identify likely pipe routes

    We work out which system is most likely involved (mains supply, heating, hot water) and the most probable runs.

  3. 3

    Acoustic testing

    We take readings at suitable points to compare sound/vibration patterns and narrow the search area.

  4. 4

    Confirm findings

    Where needed, we use additional checks to verify the likely source and reduce false positives.

  5. 5

    Next steps explained

    We explain what we’ve found and outline repair options and any access work that may be required.

Repairs can sometimes be carried out on the day depending on access, what’s found, and parts required. If not, we’ll set out the next best option clearly.

What you get at the end of the visit

You'll leave the visit with:

  • A clear explanation of findings in plain language
  • The most likely leak zone and recommended next steps
  • Advice on targeted access (if required) to limit unnecessary disruption
  • Photos and notes from the investigation where helpful
  • Repair options explained, with no pressure to proceed beyond what’s agreed

Acoustic detection and insurance documentation

Some home insurance policies include Trace and Access cover, which may contribute towards the cost of locating and exposing a hidden leak. Cover depends on your insurer and policy terms.

If you need documentation for an insurance query, we can provide a written summary of the investigation with supporting notes and images where relevant.

We do not handle claims on your behalf, but we can provide information that may help you present what was found.

Common scenarios we see

These are a few examples of where acoustic detection can help as part of the investigation:

Leak suspected under a concrete floor

Acoustic testing can help narrow the likely area before lifting finishes.

Damp patch with no obvious source

Readings can help prioritise which pipe route or zone should be investigated first.

Wet area outside

Testing can help reduce the amount of excavation needed to confirm the source.
