How do I know if I have a hidden water leak?

Check your water meter with all taps and appliances off. If the dial is still moving, you have a leak. Other signs include unexplained damp patches, mould, a high water bill, or the sound of running water when nothing is on.

Can you find a leak under a concrete slab?

Yes. Terry uses pressure testing and acoustic detection equipment to locate leaks under slabs without breaking concrete unnecessarily. Once found, the repair is targeted to the exact spot.

How much does leak detection cost?

Leak detection in the Berala area typically costs $200–$400 depending on complexity. This includes locating the leak and providing a quote for the repair. Simple leaks are often repaired in the same visit.

Leak Detection in Berala & Western Sydney

A water leak you can't see can cost hundreds on your water bill and cause serious structural damage. Terry uses pressure testing and acoustic detection to find leaks in walls, under slabs, and in buried water mains without tearing up your property.

Hidden leaks are one of the most common calls Terry gets. The signs are usually the same: a water bill that's doubled for no reason, damp patches on walls or ceilings, or the sound of running water when everything's turned off.

The approach is methodical. Terry isolates sections of your plumbing to identify which line is leaking, then uses acoustic listening equipment to pinpoint the exact location. Most leaks are found and repaired in a single visit.

In the Berala and Auburn area, common leak sources include corroded galvanised pipes (still common in homes built before 1970), failed copper joints under slabs, and cracked PVC fittings from ground movement. Terry can repair or reroute the affected section depending on what makes sense for your property.
