Water Leak Detection Sydney

Watch for an unexplained spike in your water bill, damp or stained patches on ceilings, walls or floors, a musty smell in closed-up spaces, lower pressure at the taps, the sound of running water when everything’s switched off, or warm patches on the floor that suggest a hot water pipe underneath. Any of those, give us a call for a proper assessment.

We use acoustic detectors, thermal cameras, moisture meters, tracer gas and CCTV pipe cameras. Using more than one method means we can confirm the location with confidence before recommending that anything gets opened up. Less guesswork, less unnecessary damage.

Most residential detection jobs come in between $150 and $300, depending on the property size and how complex the investigation is. Tracer gas or extended CCTV work can add to that. We give you the price upfront before anything starts. In most cases the detection cost comes back quickly through lower water bills and avoided repair costs.

Yes, slab leaks are a regular part of what we do. Acoustic ground microphones and thermal imaging locate the leak before we touch the concrete. For deep slab leaks that are hard to pinpoint acoustically, tracer gas works well. In most cases we can narrow it down well enough that only a small section needs breaking out.

Most residential jobs take one to two hours. A simple leak with an obvious trail can be quicker. Multiple potential sources, hard-to-reach areas or tracer gas work takes longer. We give you a realistic estimate when you book, and we’ll let you know on the day if it’s running over.

Most building and contents policies cover detection costs when the inspection relates to a water damage claim, particularly for sudden or accidental leaks. Some cover detection costs where it prevented damage from happening. It varies by policy, so check your PDS. We can write up a report of the leak source, method used and findings, which insurers often ask for.

The spots most likely to have hidden leaks: bathrooms (shower recesses, toilet connections, under the bath), kitchens (under the sink, dishwasher connection), the laundry, around the hot water system, beneath upper-floor wet areas where pipes run down, and any wall or ceiling next to or below a neighbour’s plumbing. We check all of these during an assessment.

Yes, outdoor and underground detection is part of what we do. Ground microphones and line tracing technology locate leaks in buried irrigation lines, outdoor supply pipes, pool plumbing and other external systems. Outdoor leaks often go unnoticed for a long time because the water just drains away rather than staining a ceiling or leaving damp patches inside.

Condensation sits on surfaces, comes and goes with temperature and humidity changes, and usually clears up when you open a window. A leak creates dampness that sticks around no matter how much ventilation there is, often stains or shows efflorescence in the same spot, and can make the surface material start to soften. If you can’t tell which one it is, a moisture meter reading during an inspection will give you a clear answer.

Annual plumbing inspections do the most work here. If your supply pressure is above 500 kPa, a pressure regulator takes stress off pipe joints and fittings. Replace older braided hoses on appliances before they split, check bath and shower silicone seals each year, and turn the water off at the mains when you’re away for a while. Smart sensors and automatic shutoff devices are worth adding on top of all that.
