Our Method

Leak Detection & Repair Process

Fast, precise, and minimally invasive

1. Assess & Listen

We discuss symptoms, inspect plumbing fixtures, and perform isolation tests to narrow down the leak zone.

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.

What We Find

Types Of Water Leaks We Detect & Repair

From visible drips to hidden underground leaks

Hidden Pipe Leaks

Critical Priority

Leaks concealed behind walls, under slabs, or within ceilings detected using acoustic listening, thermal imaging, and moisture mapping technology.

Burst Pipe Emergencies

Critical Priority

Sudden pipe failures from freezing, corrosion, high pressure, or physical damage requiring immediate isolation and emergency repair services.

Dripping Taps & Fixtures

Medium Priority

Worn washers, cartridges, or seals in kitchen and bathroom taps wasting up to 20,000 litres annually per dripping tap.

Leaking Toilets

High Priority

Running cisterns, faulty inlet valves, and pan seal leaks wasting hundreds of litres daily and potentially damaging bathroom floors.

Hot Water System Leaks

High Priority

Pressure relief valve drips, corroded tanks, failed connections, and pipe leaks from hot water units causing water waste and energy loss.

Slab & Foundation Leaks

Critical Priority

Underground supply line leaks beneath concrete foundations detected with acoustic correlators and thermal cameras before structural damage occurs.

Warning Signs

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.

Our Technology

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.

Thermal imaging leak detection technology

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.

FAQs

Water Leak FAQs

Expert guidance from Sydney leak specialists

How do I know if I have a hidden water leak?
Signs include unexplained water bill increases (20%+), damp patches on walls/ceilings, musty smells, mould growth, decreased water pressure, sound of running water when all taps are off, warm spots on floors (hot water leaks), or visible meter movement when no water is being used.
How do you find hidden water leaks without destroying my home?
We use non-invasive leak detection technology including thermal imaging cameras (detect temperature changes), acoustic listening devices (hear water escaping), moisture meters, tracer gas detection, and pressure testing. These methods locate leaks accurately without unnecessary damage to walls, floors, or gardens.
Will my insurance cover water leak detection and repairs?
Most home insurance policies cover sudden, unforeseen water leaks and resulting damage, including detection costs. However, gradual leaks from poor maintenance may not be covered. We provide detailed reports and invoices suitable for insurance claims. Check your specific policy for coverage details.
How much does leak detection cost in Sydney?
Professional leak detection typically costs $250-$500 depending on property size and complexity. This investment often saves thousands by preventing ongoing water damage and eliminating expensive exploratory demolition. Many insurers cover detection costs when a leak is found and claimed.
Can you fix leaks in walls and under floors?
Yes, after precisely locating the leak, we'll access it with minimal damage, repair the leak, then arrange restoration of building materials. For leaks in concrete slabs, we often use pipe relining to fix leaks without excavation. We coordinate with builders, tilers, and plasterers for seamless repairs.
Why is my water bill so high but I can't see any leaks?
Underground leaks, leaking toilet cisterns (can waste 200L+ daily), slow dripping taps, faulty irrigation systems, and pool equipment leaks are common hidden water wasters. We'll perform a comprehensive leak audit to identify and fix all sources of water loss.
What should I do if I discover a water leak?
Turn off the water at the mains immediately to prevent further damage. Turn off electricity if water is near powerpoints or electrical appliances. Move valuables and furnish ings from the affected area. Take photos for insurance. Then call us for emergency leak repairs - we're available 24/7.
How quickly can you attend to fix water leaks?
For emergency leaks causing active flooding or property damage, we provide rapid response aiming for 60-minute arrival across metro Sydney. For suspected leaks without active damage, we can typically attend same-day or next-day. Call 0404 939 121 for immediate assistance.
