San Diego County · Detection
Pinpoint hidden leaks under concrete foundations without breaking up the whole slab.
When Tom H. in Point Loma, San Diego called about the sound of running water when every fixture in the house is off, a technician got out the same week. San Diego's coastal neighborhoods like La Jolla, Point Loma, and Ocean Beach sit in salt-laden marine air that accelerates corrosion on copper slab lines faster than most inland California markets, and the region's decomposed granite and clay soil in canyon-adjacent communities like Clairemont shifts seasonally with the area's wet-winter, dry-summer cycle, stressing slab plumbing installed during the postwar boom of the 1950s and 60s. Instead of guessing and re-testing for weeks, the location was confirmed on the first visit and handed straight to repair.

San Diego's coastal neighborhoods like La Jolla, Point Loma, and Ocean Beach sit in salt-laden marine air that accelerates corrosion on copper slab lines faster than most inland California markets, and the region's decomposed granite and clay soil in canyon-adjacent communities like Clairemont shifts seasonally with the area's wet-winter, dry-summer cycle, stressing slab plumbing installed during the postwar boom of the 1950s and 60s.
Water service in San Diego is provided by the City of San Diego Public Utilities Department, 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.

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.
“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.”
“Pinhole leak in a copper line behind the shower wall. Non-invasive detection meant our contractor only had to open a small section of drywall instead of the whole bathroom wall.”
“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.”
