Unexplained high water bills
Warm or damp spots on your floors
Cracks appearing in walls, floors, or foundations
The sound of running water when no taps are on
Low water pressure throughout your property
Mould or mildew growth on flooring or lower walls
Water pooling around the base of your home
A constantly running water meter

If you said yes to any of the above, you may need professional slab leak detection services. At G.X.R Plumbing & Gas, we specialise in locating hidden slab leaks quickly across the entire Perth metro area.

Using advanced acoustic leak detection technology and non-invasive testing methods, our licensed plumbers can pinpoint the source of your slab leak beneath concrete without unnecessary digging or disruption.

Early slab leak detection can save you thousands in long-term repair costs.

Our Perth slab leak detection specialists can identify and repair:

Underground pipe leaks beneath concrete slabs
Hot and cold water pipe leaks
Leaks causing foundation cracks or movement

Accurate Slab Leak Detection Beneath Concrete Foundations

Slab leaks are one of the most difficult plumbing issues to detect because they occur beneath concrete. Without specialised equipment, finding the exact source can lead to unnecessary damage and guesswork.

At G.X.R Plumbing & Gas, we use a combination of acoustic leak detection, pressure testing, and moisture detection tools to accurately locate leaks beneath slabs. This allows us to pinpoint the issue without tearing up large sections of flooring or concrete.

Our approach reduces repair costs, limits disruption, and ensures the leak is fixed correctly the first time.
