Leak Detection in St George & Sutherland Shire
Ground conditions across St George and the Shire make leaks unusually easy to hide. Sandstone shelves through Menai, Illawong, Sutherland and Engadine mean water escaping from a buried pipe runs along rock rather than surfacing, often appearing dozens of metres downhill or not at all. Steep blocks amplify that, so the damp garage wall is frequently nowhere near the failure. On the coast at Cronulla and Caringbah, salt air pits copper and produces slow pinhole leaks inside walls and under tiled bathrooms. Kogarah and Hurstville add apartment buildings where a leak crosses between lots and needs proving before anyone approves a repair. We confirm the loss at the meter, then locate it acoustically and thermally before opening anything.

Recent leak detection jobs in St George & Sutherland Shire
Water tracking on rock, Illawong
Water appeared at a lower retaining wall with nothing wet above. Isolation testing showed a leaking buried main uphill, running along a sandstone shelf. We located, exposed and repaired it at the actual failure point.
Bathroom pinhole, Cronulla
A stained ceiling below a bathroom had no visible source. Thermal imaging found a salt-pitted hot line behind the tiles. Two tiles came out, the section was replaced and the area reinstated.
Cross-lot leak, Kogarah
An apartment ceiling kept staining. Pressure testing the units above identified the failing line, and we supplied strata with a written report so the correct owner's repair could be approved.
