California Service · Detection
Locate leaks in buried main water lines and irrigation systems before they surface.
The Silva Family, who lives in Canyon Crest, Riverside, reached out after noticing a sinkhole or settling ground above a buried line. Acoustic correlators listen for the specific sound signature of pressurized water escaping underground, while tracer gas can be introduced into the line and detected at the surface directly above a leak, letting us mark a precise dig site instead of trenching the entire line. What looked like it might mean tearing out a whole room turned into a same-day, targeted fix once the exact spot was confirmed.

The main line running from the water meter to your house, along with any underground irrigation lines, can develop a leak long before it ever reaches the surface. Soil often absorbs the water for a while, which means the yard can look normal even as the leak grows. We use acoustic ground microphones and tracer-gas methods to trace buried lines and identify the leak's position without trenching the entire run.

Same-day slots are available across California for active leaks.
A technician arrives with acoustic listening equipment, thermal imaging, and pressure or camera tools matched to your specific leak type.
The leak's exact location is marked and explained to you in plain terms, so nothing gets opened up on a guess.
You receive a written diagnostic report you can hand to your plumber, restoration team, or insurance company, with repair or fix options discussed on the spot.
We provide underground & main line leak detection for homeowners, property managers, and businesses throughout the state, including these service areas:
“The floor in our hallway had a warm spot for weeks. They found the slab leak in under an hour with the listening equipment and marked a tiny area instead of tearing up the whole hallway. Huge relief.”
“Our water bill jumped for two months straight and we couldn't find why. Turned out it was a slow leak behind the water heater. Professional, on time, and explained everything on the spot.”
“Salt air had corroded a fitting outside near the meter box. They traced it with the acoustic equipment without digging up my whole side yard first. Appreciated the straightforward report.”
“Good experience overall, technician was knowledgeable and thorough. Took a little longer than expected but they were clearly being careful about pinpointing the exact spot before marking it.”
“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”
“Ground near our garage had been soft for a while. Turned out to be the main line. They marked the exact dig spot and our plumber only had to open a two-foot section instead of the whole path.”
