Los Angeles County · Detection
Non-invasive detection for hidden leaks inside walls, ceilings, and under floors.
The Solano Family, who lives in Highland Park, Los Angeles, reached out after noticing a musty odor in a room with no obvious source. A lot of Los Angeles housing stock, particularly in older neighborhoods like Hollywood, Los Feliz, and Eagle Rock, still runs its original galvanized or early-generation copper supply lines from construction decades ago that's well past a typical service life. Add in LADWP's tiered water rate structure, where usage above your allotted tier costs meaningfully more per unit, and a hidden interior leak in an LA home tends to show up as a sharper bill jump than the same leak would cause somewhere with flat-rate water pricing. A problem that had been dragging on for months was pinpointed in under two hours.
— The Solano Family, Highland Park, Los Angeles
A lot of Los Angeles housing stock, particularly in older neighborhoods like Hollywood, Los Feliz, and Eagle Rock, still runs its original galvanized or early-generation copper supply lines from construction decades ago that's well past a typical service life. Add in LADWP's tiered water rate structure, where usage above your allotted tier costs meaningfully more per unit, and a hidden interior leak in an LA home tends to show up as a sharper bill jump than the same leak would cause somewhere with flat-rate water pricing. That's often the first sign an LA homeowner notices before any visible water damage does.
Water service in Los Angeles is provided by LADWP, 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.
Not every leak announces itself with a puddle. Many hidden water leaks develop slowly inside a wall cavity, under a cabinet, or above a ceiling, and are only noticed once staining, warped material, or a spike in the water bill shows up. Our general water leak detection service covers the full interior plumbing system: supply lines, fixture connections, water heaters, and any point where a line runs through a wall, floor, or ceiling.
We start with a whole-home pressure and usage check to confirm whether a leak exists, then use acoustic listening devices and moisture meters to trace it to a specific wall section, joist bay, or fixture, rather than opening multiple areas to search.

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.”
“Called about a gas smell near our meter and they were incredibly clear about safety steps over the phone before even arriving. Found the leak point and coordinated next steps with the utility.”
“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.”
