Leak Detection in the Inner West
Suspect a hidden water leak in your Inner West home? We use non-invasive leak detection technology to pinpoint leaks in walls, floors, slabs and underground pipes — without tearing your home apart.
A high water bill, damp patches or the sound of running water can all signal a hidden leak. We find it accurately, then repair it and back the work with our lifetime guarantee.

Leak Detection questions
How do you find a hidden leak?
We use acoustic, thermal, moisture and pressure-testing equipment to pinpoint the leak before opening anything up.
Can you detect leaks under a concrete slab?
Yes — slab leaks are one of the most common jobs we handle, and we can locate them without demolishing the whole floor.
Why is my water bill so high?
A sudden increase with no change in usage usually points to a hidden leak — worth investigating quickly to limit damage.
Do you repair the leak too?
Yes — we locate and repair the leak, then make good the area, all backed by our warranty.
