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.

How we handle leak detection in St George & Sutherland Shire
1. Isolate and pressure test
We shut off sections of the system and watch the meter and gauge. That confirms there really is a leak, tells us whether it is on the hot or cold side, and narrows it to a section of the property before anything is opened up.
2. Acoustic and thermal location
Acoustic equipment listens for the sound of water escaping under slabs and paving, while thermal imaging shows temperature patterns through floors and walls. Together they pinpoint the leak rather than leaving us to guess a metre either way.
3. Non-destructive access
Once the leak is marked, we open the smallest area that lets us reach it, whether that means a single tile, a small slab core or a neat wall access panel, instead of demolishing a bathroom to find one pipe.
4. Repair and verify
We repair the failed section, re-pressurise the system and re-check the meter with everything closed. You get a report showing where the leak was, what caused it and confirmation the system now holds pressure.
Every job is quoted on site and agreed in writing before work starts, so there are no surprises.
