Fast, precise, and minimally invasive
1. Assess & Listen

2. Trace With Technology
Acoustic, thermal, tracer gas, and moisture readings identify the exact leak position with minimal disruption.
3. Repair & Restore
We complete on-the-spot repairs or plan targeted replacements, then restore surfaces neatly.
4. Verify & Prevent
Post-repair pressure testing confirms success, and we provide water-saving advice and monitoring tips.
Common Warning Signs
If you notice any of the signals below, book a leak inspection before damage escalates. Early detection saves on repairs and water bills.
Unexplained bill increases
A sudden spike in water usage usually indicates a concealed leak in supply lines or fixtures.
Meter spinning while taps are off
If the metre dial keeps turning, water is escaping somewhere on your property.
Damp walls or ceilings
Discolouration, peeling paint, or mould growth suggest ongoing moisture behind surfaces.
Warm floor spots
Hot spots can highlight a burst hot water line under slab or within screed.
Types Of Water Leaks We Detect & Repair
From visible drips to hidden underground leaks
Hidden Pipe Leaks
Critical PriorityLeaks concealed behind walls, under slabs, or within ceilings detected using acoustic listening, thermal imaging, and moisture mapping technology.
Burst Pipe Emergencies
Critical PrioritySudden pipe failures from freezing, corrosion, high pressure, or physical damage requiring immediate isolation and emergency repair services.
Dripping Taps & Fixtures
Medium PriorityWorn washers, cartridges, or seals in kitchen and bathroom taps wasting up to 20,000 litres annually per dripping tap.
Leaking Toilets
High PriorityRunning cisterns, faulty inlet valves, and pan seal leaks wasting hundreds of litres daily and potentially damaging bathroom floors.
Hot Water System Leaks
High PriorityPressure relief valve drips, corroded tanks, failed connections, and pipe leaks from hot water units causing water waste and energy loss.
Slab & Foundation Leaks
Critical PriorityUnderground supply line leaks beneath concrete foundations detected with acoustic correlators and thermal cameras before structural damage occurs.
When You Need Professional Water Leak Detection
Don't ignore these red flags—early detection prevents costly damage
Unexplained Water Bill Increases
A sudden spike in water consumption without changes to your usage patterns typically indicates a hidden leak somewhere in your supply lines or fixtures. Even small leaks can waste thousands of litres monthly.
Water Metre Running When Everything is Off
Turn off all taps, appliances, and irrigation, then check your water metre. If the dial continues spinning, water is escaping somewhere on your property and requires immediate investigation.
Damp Walls, Ceilings, or Floors
Water stains, peeling paint, bubbling wallpaper, mould growth, or musty odours indicate ongoing moisture intrusion from concealed pipe leaks behind surfaces or under flooring.
Warm or Cold Floor Spots
Unexplained warm patches can reveal hot water pipe leaks under slabs or within floor screed. Cold damp spots similarly indicate cold water supply line failures requiring urgent attention.
Sound of Running Water
Hearing water flowing through pipes when all fixtures are off suggests an active leak. The noise often becomes more noticeable at night when ambient sounds are reduced.
Foundation Cracks or Shifting
Underground leaks can erode soil beneath foundations causing cracks, uneven floors, or doors that no longer close properly. Address immediately to prevent structural damage escalation.
Advanced Leak Detection Technology
Non-invasive equipment locates leaks with precision
Acoustic Leak Detection
Sensitive microphones and digital correlators amplify leak sounds in pressurised water lines. This technology pinpoints leaks beneath concrete, tiles, and walls with centimetre accuracy without excavation.
Thermal Imaging Cameras
Infrared cameras detect temperature variations caused by escaping water. Hot water leaks show as warm spots, while cold water leaks create cool zones—both visible through walls and floors.
Moisture Meters & Mapping
Electronic moisture detection probes measure dampness levels within building materials to trace leak pathways from their source through affected areas without invasive testing.
Tracer Gas Technology
Safe hydrogen and nitrogen gas mixtures are introduced into drained pipes. Gas escapes at leak points where sensitive detectors pinpoint even the smallest failures in inaccessible locations.
Pressure Testing Equipment
Hydraulic test pumps maintain constant pressure on isolated pipe sections. Pressure drop rates calculate leak severity and verify repairs are successful before closing walls.

Non-Invasive Detection
Our advanced technology locates 95% of leaks without demolition, drilling, or excavation. When access is required, openings are minimised and professionally restored. Every detection includes documented evidence for insurance claims or strata reports.
