Leak Detection Brisbane: How We Find Leaks Other Plumbers Miss

Posted on June 6, 2026

A hidden water leak in your Brisbane home can go undetected for months while your water bill climbs and moisture quietly damages your walls, floors, and foundations. The old approach — dig it up and find it — is costly and disruptive. Plumbing Bros uses advanced electronic leak detection equipment to locate leaks precisely, minimising damage to your property and getting straight to the fix.

Signs you have a hidden leak in Brisbane

  • Your water bill has increased without an obvious reason
  • There are wet or damp patches on walls, ceilings, or floors
  • You can hear water running when all taps are off
  • There is mould or mildew in areas that shouldn’t be damp
  • Your water meter is moving when everything is turned off
  • There are soft or sunken areas in your lawn, which can indicate a leaking underground supply line

How we detect leaks in Brisbane

Our Brisbane leak detection process uses a combination of tools to locate leaks without unnecessary demolition:

  • Thermal imaging — detects temperature differences behind walls and under floors caused by water movement
  • Acoustic listening devices — amplify the sound of water escaping from pressurised pipes, allowing us to pinpoint the leak location to within centimetres
  • Moisture meters — measure moisture content behind surfaces to map the spread of water damage
  • Pressure testing — isolates sections of pipework to identify where pressure is dropping

Common leak types in Brisbane homes

  • Slab leaks — leaks in pipes running under the concrete slab of Queensland’s many slab-on-ground homes. These require precise location before any concrete cutting
  • Roof space leaks — copper pipes in roof spaces develop pinhole leaks over time as the pipe oxidises
  • Shower leaks — failed grout and silicon behind tiles allows water to penetrate walls. Often not discovered until mould appears or tiles start moving
  • Garden supply leaks — irrigation line and tap connections under driveways and in garden beds can leak for months undetected

“Plumbing Bros helped us locate a hidden leak that other plumbers could not find. Their equipment and experience made a huge difference and saved us from further damage.”

FAQs about leak detection in Brisbane

How much does leak detection cost in Brisbane?

Leak detection in Brisbane typically costs $150–$400 for the detection assessment. The cost of repairs depends on what’s found. We provide a fixed quote for repairs before any work starts.

How do I check if I have a water leak?

Turn off all water-using appliances and taps. Locate your water meter — usually near the front boundary. If the dial is still moving, there is an active leak somewhere in your system.

Can you detect a slab leak without breaking the concrete?

In most cases, yes. Our acoustic detection equipment can locate a slab leak to within 10–20cm, meaning the concrete cutting required is minimal. We confirm the location with pressure testing before cutting.
