Our Leak Detection Services

Water Leak Detection

Hidden water leaks inside walls, under floors and through building structures are among the most damaging and costly problems a Sydney property can face. Left undetected, they cause water damage, structural deterioration, timber rot and mould growth.

Our team uses thermal imaging cameras and moisture detection equipment to map moisture activity behind surfaces — locating the precise leak source without unnecessary cutting, drilling or demolition. Whether the leak is in a residential wall cavity, a commercial ceiling void or a multi-story building, we find it accurately and document it in full.

Shower & Bathroom Leaks

Leaking showers are one of the most common plumbing issues in Sydney homes and apartment buildings. They are also one of the most misdiagnosed. Water can travel significant distances from the original source before becoming visible, making accurate detection essential before any repairs begin. Our shower leak detection service assesses all potential failure points: waterproofing membranes, grout and silicone joints, waste pipes and puddle flanges, shower screen seals, drain connections and shower recess gradient. We also check basins, toilets and cisterns for related leaks that may be contributing to the problem. By identifying the true cause rather than treating symptoms, we help you avoid costly repeat repairs.

Underground Pipe Leaks

Leaking underground supply lines and stormwater pipes are notoriously difficult — and expensive — to find without the right equipment. Signs include soggy ground, unexplained drops in water pressure, or a water meter that keeps ticking when every tap is off. Our electro-acoustic and tracer gas technology allows us to pinpoint underground leaks to within centimeters, without excavating large sections of your yard, driveway or paving. We confirm the exact position before any digging begins — saving you significant cost and property disruption.

Roof Leak Detection

Roof leaks are deceptive. They often only appear during heavy or directional rain and the water entry point can be located well away from where the stain appears on your ceiling. Our team inspects all critical areas of the roof system: flashing, roof surfaces, joints, fixtures, gutters and downpipes. We identify leak paths caused by weather-dependent conditions and trace water intrusion back to its source. All findings are documented with photographs and a written report.

Slab & Under-Floor Leaks

Warm or wet spots underfoot, cracked or lifting tiles, or a persistently high water bill may all point to a leaking pipe beneath your concrete slab. Slab leaks require fast action — left unaddressed, they can undermine foundations, damage flooring and cause significant structural harm. Evolution Plumbing uses thermal imaging cameras and electro-acoustic equipment to locate under-slab leaks precisely. By confirming the exact position before recommending any concrete breaking, we keep the repair area as small as possible.

Moisture, Mould & Water Damage

Persistent moisture trapped inside walls, subfloor spaces or roof cavities leads to more than just water damage. Over time it causes structural rot, failure of insulation, health risks from mould spores, and reduced property value. Our moisture detection equipment measures the moisture content of timber, plasterboard, masonry and screed across all affected building elements. We identify the extent of moisture infiltration, trace it to the source, and provide recommendations for both leak repair and remediation of any resulting damage.

Our Leak Detection Technology

At Evolution Plumbing, we use five professional-grade detection technologies to ensure every leak is found accurately, efficiently and with minimal disruption.

Thermal Imaging Camera Thermal cameras detect the temperature differential caused by evaporating or pooling water, creating a precise visual map of moisture activity behind walls, ceilings and floors. Completely non-invasive, thermal imaging is one of the most powerful tools available for identifying hidden leaks in both residential and commercial buildings.

Electro-Acoustic Technology Water escaping from a pressurised pipe produces a distinctive sound signature — higher frequency for smaller leaks, lower frequency for larger ones. Our electro-acoustic listening equipment amplifies and analyses these sounds through surfaces and soil, pinpointing the exact leak location along buried or concealed pipework.

Tracer Gas Detection A non-toxic, non-flammable tracer gas is injected into the pipe under test. Our electronic detector then traces where the gas escapes at the surface, enabling highly accurate detection of even micro-leaks in deeply buried or inaccessible pipework — through concrete, paving, soil or landscaping.

Electronic Leak Detector Used in combination with tracer gas, our electronic leak detectors measure gas concentration at the surface with pinpoint precision. This combination is particularly effective for detecting small leaks in pipes running beneath concrete slabs, driveways or tiled courtyards.

Moisture Detection Calibrated moisture meters measure the moisture content in timber, plasterboard, screed and masonry. They are essential for mapping the extent of water infiltration and identifying building elements at risk of rot, mould or structural failure — guiding effective, targeted repairs.

How Our Leak Detection Process Works

Step 1 — Contact Us Call, text or submit our online form. We confirm your booking, provide an upfront quote and schedule a time that suits you — including same-day and emergency appointments across Sydney.

Step 2 — On-Site Inspection Our technician arrives with a full equipment kit and conducts a systematic, non-invasive assessment of the affected areas. We take the time to understand the problem before selecting the most appropriate detection method.

Step 3 — Pinpoint the Leak Using thermal imaging, electro-acoustic or tracer gas methods — or a combination — we precisely identify the leak source. All findings are documented with on- site photographs and notes.

Step 4 — Report & Repair You receive a clear written report detailing the leak location, likely cause and recommended repair scope. We carry out or coordinate the repair and can provide documentation suitable for insurance claims or strata records.

Signs You May Have a Hidden Water Leak

If you notice any of the following, contact Evolution Plumbing for an inspection:

•  Your water bill has increased unexplainably
•  You can hear the sound of running water when all taps and appliances are off
•  Damp, discoloured or stained patches on walls, ceilings or floors
•  Musty odours or visible mould growth in rooms without obvious moisture sources
•  Tiles that are cracking, lifting or becoming loose
•  Warm spots on a concrete floor or slab
•  Soft, wet or unusually green patches in your garden or lawn
