Stop Your Underground Leak Without Destroying Your Driveway

Precision Underground Leak Detection Services Across Northern Ireland.
If you have a wet patch on your drive or a "Leak Notice" from NI Water, you are likely worried about the cost of repair. You might fear that finding the leak means digging a long, messy trench through your Tarmac, block paving, or garden.

We use acoustic equipment and tracer gas to pinpoint the location of your underground water leak. This allows us to find the exact spot of the failure before any ground is broken. We aim to dig one small hole rather than a trench.

Is the Leak Your Responsibility or NI Water’s?

Many homeowners in Northern Ireland are confused by the mains water supply boundary.

NI Water is responsible for the public main and the pipe leading up to the boundary of your property. The supply pipes that run from the boundary to your house are your private responsibility.

If your water meter is spinning when no taps are on, or if you see groundwater bubbling up in your yard, the repair usually falls to you. We help you identify this boundary clearly. If the leak is on your side, we provide the underground leak detection and the repair to stop the waste.

For metered properties, a professional leak detection and repair can often help you claim a "Leak Allowance" from NI Water to offset the cost of wasted water.

How We Find the Source Without the Mess

Traditional plumbing involves guesswork and trial-and-error digging. This causes unnecessary damage to your property. We use latest non-invasive technology to detect leaks through deep soil, concrete, and driveways.

Tracer Gas:

We drain the pipe and introduce a safe, inert gas. This gas escapes through the pipe leak and rises to the surface. Our sensors pick up the exact point where the gas emerges.

Acoustic Ground Microphones:

We use sensitive listening equipment to hear the specific frequency of underground water escaping under pressure.

Pipe Locating:

We map the exact route of your underground pipe before we begin. This ensures we do not hit other utilities when digging to expose the leak.

The Full "Find and Fix" Solution

Most leak detection services only find the problem and leave you to hire a plumber or a groundworks team to fix it. This creates disruption and delay.

We offer an end-to-end service for domestic properties and commercial leak situations. We carry the heavy equipment, breakers, and excavators needed to reach deep pipework.

Our Underground Leak Detection Process

Assess:

We assess the extent of the water damage and explain your options.

3

Access:

We carefully remove a small section of your driveway or lawn.

4

Repair:

We fix the water leak underground and test the water pressure to ensure the system is sound.

5

Restore:

We backfill and tidy the area so your property returns to normal.

Common Signs of an Underground Water Leak

You may not see a puddle. Sometimes the first indication of a water leak is subtle.

  • A sudden, unexplained increase in your water bill.
  • A drop in water pressure at your kitchen tap or shower.
  • The sound of running water behind floors and walls when the house is silent.
  • The boiler losing pressure or a central heating system that requires constant topping up.
  • New mould growth or damp patches near the foundations of your home.

Insurance and Trace and Access

If you have home insurance, your policy may include "Trace and Access" cover. This pays for the cost of detecting leaks in underground locations and exposing the pipe.

Insurance companies often require a professional report to process these claims. We provide the documented evidence and photos they need to validate the source of the leak. While we cannot guarantee your claim will be accepted, our technical reports provide the clarity required by adjusters.

FAQs — How We Find Leaks Without Damage or Stress

Not sure if non-destructive leak detection is right for you?
These FAQs show how we find leaks quickly and accurately — without damage to your home.

NI Water has the legal power to issue a "Section 75" notice. This requires you to fix the pipe leak within a set timeframe (usually 14 days). If you do not act, they can eventually turn off your water supply or enter your property to carry out a forced repair and bill you for the cost. Calling a leak detection company immediately proves you are taking "reasonable steps" to resolve the issue.
