Alameda County · Detection
Locate leaks in buried main water lines and irrigation systems before they surface.
Ivan S., a Fairview, Hayward homeowner, had been living with a water meter that keeps registering usage with everything indoors shut off for weeks before calling us. Hayward's position along the Hayward Fault adds a genuine seismic factor to how buried main lines age here, on top of the usual soil and terrain considerations found throughout the East Bay. The written diagnostic report gave the follow-up contractor exactly where to cut, so the job stayed small.
— Ivan S., Fairview, Hayward
Hayward's position along the Hayward Fault adds a genuine seismic factor to how buried main lines age here, on top of the usual soil and terrain considerations found throughout the East Bay.
Water service in Hayward is provided by East Bay Municipal Utility District (EBMUD), and confirming whether an issue is on your private plumbing or the utility side of the meter is one of the first things we check.
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.
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.

Call or request an appointment online. 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.
“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.”
