Los Angeles County · Detection
Non-invasive detection for hidden leaks inside walls, ceilings, and under floors.
When Dexter M. in California Heights, Long Beach called about the water meter's leak indicator dial moving with everything turned off, a technician got out the same week. Long Beach's large stock of older multi-family buildings, especially in Downtown and the Alamitos Beach area, means an interior leak in one unit's supply line can affect water pressure or bills in adjacent units, which changes how a leak first gets noticed here. Instead of guessing and re-testing for weeks, the location was confirmed on the first visit and handed straight to repair.
— Dexter M., California Heights, Long Beach
Long Beach's large stock of older multi-family buildings, especially in Downtown and the Alamitos Beach area, means an interior leak in one unit's supply line can affect water pressure or bills in adjacent units, which changes how a leak first gets noticed here.
Water service in Long Beach is provided by the Long Beach Water 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.
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.
From Belmont Shore, Naples, Bixby Knolls to Downtown Long Beach, California Heights, Los Altos, we handle water leak detection calls across Long Beach, matching the approach to each property's age, soil, and layout.
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.
“Being this close to the water, I figured corrosion was the culprit and I was right. They found the exact fitting near the meter box that had failed. Fast and professional.”
“Our multi-family building had a mystery water bill spike. They tested each unit's supply line and found the issue in about two hours total across the building. Very organized process.”
“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.”
