Leak Detection in Sydney
Hidden leaks can waste thousands of litres of water and quietly damage your home. We use non-invasive detection tools to locate leaks accurately before repairing them.
Overview
Leak Detection in Sydney
A hidden leak shows up as a water bill that jumps for no reason, a damp patch that never dries, a musty smell, warm spots on a slab or a water meter that ticks over with every tap in the house turned off. Finding it without wrecking the property is the whole job.
We use acoustic listening equipment, thermal imaging, pressure testing and tracer methods to pinpoint the leak before anything is opened up. Once located, we mark it precisely so the repair is a single targeted access point rather than a wall or slab pulled apart in stages.
We also provide written reports and photos for insurance claims, which most insurers now require before they will consider a water damage claim.
