Underground Leaks

A leak underground can run for months undetected — driving up your water bill and slowly damaging your property. We use specialist equipment to find it fast, with minimal disruption.

C Caroline Lowe Google review · Verified ★★★★★

After a leak was detected near my driveway, Kevin very carefully jack-hammered through and found the leaking pipe. He removed the pipe, replaced it with a new one, cemented over it and very neatly finished the surface. Kevin is an excellent plumber and problem solver — I would recommend him for any plumbing job.

Underground Leaks

Finding Leaks Underground

Underground leaks are the hardest to find — and the most damaging if left. Our specialist equipment locates the exact point before any excavation begins.

Acoustic Ground Microphones Our Sewerin equipment listens through concrete, asphalt and soil to detect the sound of escaping water — pinpointing the leak to within centimetres.

Tracer Gas Technology We pressurise your pipes with a harmless gas that escapes at the leak point and rises to the surface, detected by our electronic sniffer above ground.

Minimal Excavation We only dig at the confirmed leak location — not exploratory trenches across your property. One small excavation, leak repaired, reinstated neatly.

Driveways & Slabs We regularly locate leaks under concrete driveways, pool surrounds and slabs — using jackhammers only where we've confirmed the exact location.

Water Main Leaks We detect leaks on your side of the water meter — including mains supply pipes running underground from the street to your home.

Leak Found or It's FREE* If we can't find it using our full suite of equipment, you don't pay. That's our guarantee.

Common questions

Underground Leaks questions

How do I know if I have an underground leak?
Common signs include a water bill that's higher than usual, wet patches on dry days, sinkholes or soft spots in your lawn, or a water meter that keeps ticking when all taps are off.
Will you have to dig up my whole driveway?
No. We locate the leak precisely first using acoustic and tracer gas equipment, then excavate only at the confirmed point.
How deep can you detect leaks?
Our equipment can detect leaks at significant depth — most residential underground pipes are within 600mm–1.2m of the surface, well within our detection range.
Can you repair the pipe once found?
Yes — as licensed plumbers we carry out the repair, reinstate the surface and leave your property neat. One call, fully sorted.
