Alameda County · Detection
Non-invasive detection for hidden leaks inside walls, ceilings, and under floors.
The Okoro Family, who lives in Grand Lake, Oakland, reached out after noticing the water meter's leak indicator dial moving with everything turned off. Oakland's older flatland neighborhoods, including Fruitvale and parts of East Oakland, still run original pre-1960s galvanized supply lines in many homes, well past a typical service life and a common source of interior leaks. Instead of guessing and re-testing for weeks, the location was confirmed on the first visit and handed straight to repair.

Oakland's older flatland neighborhoods, including Fruitvale and parts of East Oakland, still run original pre-1960s galvanized supply lines in many homes, well past a typical service life and a common source of interior leaks.
Water service in Oakland is provided by East Bay Municipal Utility District (EBMUD), 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.
“Hillside home with a soft patch of yard that never dried out. Acoustic testing traced it to the main line about 15 feet from where we expected. Saved us from digging in the wrong spot entirely.”
“Great communication throughout, showed up when they said they would, and gave a clear written report I could hand to my plumber.”
“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.”
