Service Overview

An underground water main leak can waste thousands of litres of water every day, leading to high water bills and ground subsidence around your property. Because these leaks are buried deep under lawns, driveways, or gardens, they often go unnoticed for months. We provide specialised external leak detection services across Sydney, utilizing high-powered acoustic microphones and tracer gas to find hidden failures without digging up your yard. We understand how Sydney’s varied soil conditions — from coastal sand to western clay — can stress underground pipes. With over 25 years of experience, we provide a 60-minute emergency response to find the leak and offer an upfront quote for the fix today.

What You Get

Our external leak detection service is a comprehensive diagnostic package designed for deep underground pipework. We don’t just guess where the wet patch is; we use industrial-grade technology to pinpoint the exact failure point. The service includes the use of high-frequency ground microphones to hear escaping water and tracer gas injection for deep or difficult terrain. We also perform a meter-based pressure test to confirm the exact rate of water loss. You receive a detailed location report and an upfront fixed-price quote to repair the leak on the spot. We offer a $0 callout fee if you book before 4pm today.

What We Handle

We handle external leak detection for all types of residential and commercial properties throughout the Sydney basin. Our scope covers main water supply lines under lawns, fire service lines in commercial car parks, and irrigation systems in large suburban estates. We are experts at locating failures in old galvanized steel, modern copper, and high-density poly pipework. Whether you have a leak under a concrete driveway in the Eastern Suburbs or deep within a garden bed in the Hills District, our licensed team has the technical credible expertise to find it. We ensure every fix complies with Sydney Water regulations and local council requirements today.

How We Get It Done

We begin by conducting a pressure test at your main water meter to determine if the leak is on the main supply line. After Providing an upfront quote, we use ground microphones to ‘sweep’ the path of your underground pipes, listening for the specific high-frequency sound of water escaping under pressure. For difficult-to-hear leaks, we inject a safe tracer gas into the line and use a sniffing probe to find where the gas emerges from the soil. Once the leak is pinpointed, we provide a fixed price for the targeted excavation and repair. Most yard repairs are completed in a few hours. Save $65 by booking online today. Our family-owned team delivers reliability you can trust.

Why It Matters for Your Home

The value of professional external leak detection is the prevention of foundation damage and massive water bill credits. A leaking main can cause ‘sinkholes’ and ground subsidence that cracks your house walls. By pinpointing the leak before digging, we save your landscaping and driveway from unnecessary destruction. As a family-owned Sydney business for 25+ years, we focus on providing a fix that is technically credible and permanent. Our upfront pricing ensures transparency, and our lifetime workmanship guarantee gives you long-term security. We’ve helped over 10,000 homes protect their assets with 4.9 stars. Our $0 callout fee makes starting easy today.
