Find hidden leaks and prevent damage

Water damage destroys structural integrity. We use advanced thermal imaging and moisture meters to locate the source of hidden leaks before they cause costly damage.

Water Leak Inspection NSW

"Our strata committee spent six months and $30,000 replacing bathroom tiles - and the leak came back the next week. The source was never the tiles. It was a failed flexi-hose behind the wall."

Water damage compounds silently. Left unfound, a single failed seal can cost tens of thousands in structural repairs, mould remediation, and strata disputes.

  • Advanced thermal imaging technology to detect hidden moisture without breaking walls or tiles
  • Pinpoint diagnostic reports that identify the exact leak source — not just the symptom
  • Strata-ready findings that clearly establish whether a leak is common property or private lot responsibility
  • Independent of plumbers, waterproofers, and repairers — our only obligation is an accurate diagnosis

Scope of Works

Common leak sources we identify

Water rarely travels in a straight line. We find the true source.

Failed Waterproofing

We test wet areas to see if the membrane has ruptured or deteriorated.

We:

We assess the building's history and plan our diagnostic approach.

Consultation

Thermal & Moisture Scanning

You:

Provide access to the affected and surrounding rooms.

We:

We use infrared cameras and deep-penetrating moisture meters to trace the water's path to its origin.
