Pinpoint hidden leaks under concrete foundations without breaking up the whole slab.
The Isham Family, who lives in Montanoso, Mission Viejo, reached out after noticing unexplained cracks in flooring, drywall, or the foundation itself. Mission Viejo's status as one of the country's original master-planned communities, built around Lake Mission Viejo since the 1960s, means slab construction era is fairly consistent across most of the city. A problem that had been dragging on for months was pinpointed in under two hours.

Mission Viejo's status as one of the country's original master-planned communities, built around Lake Mission Viejo since the 1960s, means slab construction era is fairly consistent across most of the city.
Water service in Mission Viejo is provided by Moulton Niguel Water District, 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.
A slab leak happens when a hot or cold water line running beneath your home's concrete foundation develops a crack, pinhole, or corrosion failure. Left alone, it can warp flooring, feed mold behind walls, and quietly inflate your water bill for months. Our technicians use acoustic listening equipment, infrared thermal cameras, and static pressure testing to find the leak's exact position before a single inch of concrete is opened.
Because slab leaks are hidden under structural concrete, guesswork digging is expensive and destructive. We combine electronic amplification with thermal imaging to narrow the leak to a small, marked area, so any follow-up access work is as limited and targeted as possible.

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.”
