Leak Inspection
& Diagnosis Sydney
Accurate diagnosis is everything. Before a single tile is touched, our technicians use moisture meters, thermal imaging, pressure testing and dye tracing to pinpoint the exact cause of your leak.
Why It Matters
Diagnosis Before Demolition
The majority of shower and balcony leaks are misdiagnosed on first assessment. A damp ceiling below a shower does not automatically mean the waterproofing membrane has failed. It could be grout degradation, silicone shrinkage, a plumbing joint leak, or water tracking from an entirely different wet area.
Sydney Sealed invests in proper diagnosis because getting it wrong costs you thousands in unnecessary tile removal, wrong repairs and recurring problems. Our diagnostic process is designed to identify the true source — the first time.
Key insight: In over 60% of cases we inspect, the actual leak source is different from where the visible damage appears.
Our Arsenal
Diagnostic Tools & Methods
No single tool tells the full story. We deploy a combination of technologies depending on the symptoms, building type and suspected leak source.
Electronic Moisture Meters
Pin-type and pinless moisture meters detect hidden water within walls, floors and substrates without surface damage. Readings are taken at multiple points to map the full extent of water ingress.
Thermal Imaging Cameras
Infrared thermography reveals temperature differentials caused by evaporative cooling at leak sources. Essential for identifying leaks behind tiles and within wall cavities where no surface damage is visible.
Hydrostatic Pressure Testing
Controlled water pressure testing of showers, balconies and plumbing connections confirms leak pathways and distinguishes between waterproofing failure and plumbing defects.
Flood & Dye Testing
Non-toxic coloured dye tracing in shower bases and drains confirms whether water is penetrating the waterproofing membrane or escaping through drainage faults.
Endoscopic Inspection
Flexible borescope cameras access confined spaces, wall cavities and subfloor areas to visually confirm water damage, mould growth and structural deterioration without invasive demolition.
Acoustic Leak Detection
Specialist listening equipment identifies the sound of pressurised water escaping from pipes, joints and fixtures — particularly effective in multi-storey buildings where water travels horizontally.

Watch Out For
Common Misdiagnoses
These four errors account for the majority of failed leak repairs. We see the consequences every week.
Blaming the Drain
A slow drain is often mistaken for a leak. We test drainage separately from waterproofing to confirm the actual failure point.
Tile Removal as Default
Many trades recommend full tile removal before proper diagnosis. Our methods identify when tile removal is truly necessary — and when it is not.
Ignoring Hidden Pathways
Water can travel metres from its entry point through wall cavities and ceiling spaces. Surface symptoms rarely reveal the true origin without proper testing.
One-Size-Fits-All Repairs
Different leak causes require different repairs. Grout failure, membrane breach, plumbing defect and structural movement each demand a specific solution.
