Fresno County · Detection
Non-invasive detection for hidden leaks inside walls, ceilings, and under floors.
When Beatriz C. in Sunnyside, Fresno called about the water meter's leak indicator dial moving with everything turned off, a technician got out the same week. Fresno's groundwater is notably hard, and homes drawing on well or municipal supply alike see mineral scale build up inside older fittings faster than in coastal California markets, which is often the first thing that fails in an aging Fig Garden or Tower District home. The diagnostic report was enough to move the insurance claim forward without further back-and-forth.

Fresno's groundwater is notably hard, and homes drawing on well or municipal supply alike see mineral scale build up inside older fittings faster than in coastal California markets, which is often the first thing that fails in an aging Fig Garden or Tower District home.
Water service in Fresno is provided by the City of Fresno Department of Public Utilities, 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.
“Our irrigation system was losing water and we assumed it was just old sprinkler heads. Turned out to be a leak in the underground line itself. Glad we called before digging up the whole yard ourselves.”
“Hard water here does a number on pipes. They found a pinhole leak in a joint I never would've guessed. Quick, respectful of the property, and didn't leave a mess.”
“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.”
