Our licensed and qualified plumbers can quickly detect and repair leaks in both residential and commercial plumbing. We carry all the tools necessary to fix any leak on the spot, regardless of the size of the problem or your property. Leaks can sometimes be difficult to spot, especially for larger properties. They can be hidden underground or in walls and slowly leak for months without your knowledge.

OUR ADVANCED LEAK DETECTION TECHNIQUES
We utilise four specialised, non-invasive technologies to pinpoint hidden leaks with pinpoint accuracy — no guesswork, no unnecessary digging.
Thermal Imaging
Infrared thermal cameras detect temperature differences in walls, floors, and ceilings caused by hidden hot or cold water leaks — revealing what the naked eye can't. This allows us to visually map the exact location of moisture build-up without removing a single tile or cutting into plaster.
The camera reads surface temperatures and creates a colour-coded heat map. Cooler patches indicate cold water leaks; warm areas reveal hot water pipe leaks behind walls or under floor coverings.
- Hot water slab leaks
- Behind-wall pipe leaks
- Under-floor heating faults
- No demolition required
- Instant visual results
Acoustic Listening
High-sensitivity electronic listening devices amplify the sound of water escaping from pressurised pipes, allowing us to locate underground and sub-slab leaks precisely. Ground microphones and contact sensors filter out background noise to isolate the distinct hiss of escaping water.
A sensitive ground microphone is placed along walls, floors, or soil above the suspected pipe. The device amplifies the high-frequency noise created by pressurised water forcing through a crack or joint, guiding us to the exact leak point.
- Pressurised pipe leaks
- Underground water mains
- Sub-slab leak pinpointing
- Minimal surface disruption
- Works through concrete & soil
Electronic Line Tracing
We trace the path of underground pipes and cables using electromagnetic signal technology, mapping concealed service lines before any excavation takes place. A transmitter sends a signal along the pipe and a receiver tracks it above ground, giving us a complete picture of your underground network.
An electromagnetic signal is induced onto the pipe either by direct connection or induction. A handheld receiver then follows the signal's path across the surface, recording the pipe's route and estimated depth at each point.
- Maps underground pipes
- Prevents accidental damage
- Accurate depth readings
- Locates concealed junctions
- Essential before excavation
Tracer Gas Sniffing
A safe, non-toxic gas (typically a nitrogen-hydrogen mix) is introduced into the pipe system and escapes through the leak point. Sensitive sniffers detect the gas at the surface, pinpointing even the smallest leaks that other methods might miss — ideal for notoriously difficult-to-find micro-leaks.
The pipe is pressurised with the tracer gas. The gas escapes through any crack or pinhole and rises to the surface. A gas detector is swept over the area and alerts when it registers the gas concentration, marking the leak's exact position.
- Detects micro-leaks
- Works on any pipe material
- 100% non-invasive method
- Ideal for slow / intermittent leaks
- Safe for potable water systems
CCTV Inspection
High-resolution waterproof cameras are fed deep into your pipes to visually inspect the interior of drains and sewer lines in real time. This lets us identify cracks, tree root intrusion, collapsed sections, and blockages without any excavation — giving you a clear picture of exactly what's happening underground.
A flexible, high-definition camera on a push-rod cable is inserted into an access point and navigated through the pipe. Live footage is displayed on a monitor above ground, while a built-in sonde transmitter records the camera's depth and location for precise mapping of any defects.
- Tree root intrusion detection
- Cracked or collapsed pipes
- Live real-time footage
- Pinpoint defect location & depth
- No digging required
Dye Testing
Non-toxic, environmentally safe coloured dyes are introduced into your water or drainage system to trace the flow path and reveal exactly where water is escaping or cross-connecting. This simple yet highly effective method is perfect for confirming suspected leaks in showers, pools, stormwater systems, and underground drainage networks.
A fluorescent dye tablet or liquid is introduced into the suspected fixture or pipe. The dye travels with the water flow and appears at the leak point or exit, visually confirming the source and path of the leak — even through soil, cracks, or cross-connected pipes.
- Shower & balcony leak tracing
- Stormwater & sewer cross-connection
- Swimming pool leak detection
- Confirms exact leak source
- Safe, non-toxic & eco-friendly
