A leak you can't see is still costing you water, and under a slab it's undermining something. Finding it precisely is cheaper than looking for it destructively.
No obligation. Takes 30 seconds.
Emergency Plumber Geelong does plumbing work across the Geelong and Bellarine region, including leak detection. Tell us what's happening and whether water is still running. We give you a firm price before work starts.
Turn off every tap and water-using appliance in the property. Go to the meter and note the reading, including the small dial. Wait an hour without using any water, then check it again.
If it's moved, you have a leak on your side of the meter. That's a genuinely useful piece of information to give us when you ring, and you can get it yourself.
A water bill noticeably up with no change in usage. A damp patch on a floor or a wall that doesn't dry. An area of the garden greener than the rest. The sound of running water with everything off. A warm spot on a floor, which suggests the hot line under a slab.
Where an older Geelong house still has galvanised supply pipe, corrosion can produce this pattern — pinhole leaks that do not show.
Acoustic listening equipment picks up the sound of pressurised water escaping, through concrete and soil. Thermal imaging finds temperature differences from a hot water leak. Pressure testing isolates which section of the system is losing water.
$250 to $600, and it's money well spent — it converts an unknown into a specific location before anybody opens a wall or a slab.
Once located, a slab leak can usually either be accessed directly by cutting the slab, or the affected line can be re-routed and abandoned.
Re-routing can be cheaper and less disruptive than cutting the slab. Where both are possible, we price both, so you can choose.

The ranges for this job and the call-out that comes with it.
| Job | Indicative price | What moves it |
|---|---|---|
| Emergency call-out, business hours | $120 – $250 | Attending and diagnosing. We tell you when you book whether it comes off the repair. |
| After hours, weekend or public holiday | $180 – $400 | The call-out premium. We give you the figure on the phone, before we come out. |
| Burst pipe — isolate and repair | $250 – $900 | Depends heavily on access. A pipe in a wall or under a slab must be reached first, and that work can take the total past this range. |
| Leak detection, non-invasive | $250 – $600 | Acoustic and thermal tracing to find a leak without opening walls or slab. |
