We are Australia's Original Leak Detection Specialists™

We find leaks plumbers can’t, before small signs become expensive damage. Get ahead of hidden water problems early, protect your property, and avoid a bigger repair later.

What Brought You Here Today?

Whether you've just opened a shock water bill or your pool's dropped overnight — you're in the right place. Tell us what's happening and we'll route you to the right solution. Below are the most common reasons people contact us. If yours isn't listed exactly, don't worry — we handle everything from slow drips to catastrophic water loss.

High Water Bill

Your meter's running when nothing's on. Could be an underground pipe, a hidden joint, a slow drip inside your walls, or a leaking toilet cistern. We find it fast using acoustic listening and tracer gas to pinpoint the exact location without digging.

How we Help

Pool Losing Water

If your pool's dropping faster than that, you've got a leak — and we know exactly where to look. We use every non-destructive trick in the book to find your leak.

How we Help

Damp Spots or Bubbling Paint

Moisture behind your walls, under your tiles, or on your ceiling is rarely a small problem. The sooner it's found, the less it costs to fix. We use thermal imaging to locate the source before the damage spreads.

How we Help

Locating Water Pipes & Utilities

Planning groundwork, renovations, or a pre-purchase inspection? Map every utility and water line acoustically before you cut or demolish — and prevent costly reactive repairs.

How Leak Detection Works

Most people don't know what to expect when they call a leak detection specialist. Here's exactly what happens from the moment you reach out to us, through to the moment you hand our report to your plumber.

  1. 01

    Book

    Call us, fill in our online quote form, or use our booking system. We'll confirm your appointment quickly — usually within 2 business hours. No long wait, no being put on hold with a call centre. Tell us what's happening and we'll ask a few questions to prepare our specialist with the right equipment. Most jobs are scheduled within 48 hours.

  2. 02

    Detect

    Your specialist arrives in their custom ALD vehicle. Their mobile workshops carry high-tech non-invasive leak detection equipment. We run a full assessment using acoustic sensors that listen for leaks through concrete, thermal imaging cameras that detect moisture behind walls, and tracer gas systems that trace the exact path of water flow. No guessing. No drilling to find out. The whole process is non-destructive — your floors, walls, and garden stay untouched.

  3. 03

    Report

    You receive a clear, detailed written report showing exactly where your leak is located and what equipment detected it. The report includes imagery, location coordinates, and practical notes for repair. Take it to your plumber or builder — they can repair the right spot without exploratory demolition. You save time, money, and stress. One cut, not ten.

Leak Detection Without Destruction™

Our Solution

Our Technology
Acoustic Listening

Acoustic Listening

We hear leaks through concrete, tiles, and soil without digging. Sound waves reveal what's hidden beneath every surface.

Thermal Imaging

Thermal Imaging

Infrared cameras reveal hidden moisture and heat patterns behind surfaces, under tiles, inside walls. We see what's invisible to the eye.

Tracer Gas

Tracer Gas

A safe, inert gas traces the exact path and exit point of even the smallest leak. We follow the water, not guess at it.

How Much Is Your Leak Costing You?

Small leaks escalate quickly, wasting thousands of litres and hundreds of dollars before visible signs appear. Every day a leak continues wastes your money. Water authorities charge by the kilolitre. A tiny one-litre daily drip costs you $550 annually. Larger hidden leaks in main lines or walls waste significantly more. Use the calculator below to estimate your potential water loss based on current rates. Many councils offer rebates after a verified repair. We provide the written reports required to approve these claims.

A steady drip of this size wastes approximately 100 litres per day — that's 36,500 litres per year, costing you an estimated $91.25 at current rates. Over three years, an undetected leak like this could cost you $273.75. In many cases, you can claim a rebate from your water authority if you complete repairs. Our written detection report supports these claims.
