Pinpoint hidden leaks under concrete foundations without breaking up the whole slab.
The Ibarra-Solis Family in Malaga Cove, Palos Verdes Estates noticed mildew smell or unexplained humidity in ground-floor rooms and wasn't sure how serious it was. Palos Verdes Estates' 1920s Olmsted-planned core has some of the oldest, most architecturally distinctive slab plumbing on the South Bay peninsula. The leak was marked in that same visit, and the repair crew only had to open a small section instead of the whole area.

Palos Verdes Estates' 1920s Olmsted-planned core has some of the oldest, most architecturally distinctive slab plumbing on the South Bay peninsula.
Water service in Palos Verdes Estates is provided by California Water Service, 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.

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.”
