Santa Clara County · Detection
Non-invasive detection for hidden leaks inside walls, ceilings, and under floors.
Odalys E. in Willow Glen, San Jose noticed warped baseboards, cabinets, or flooring near plumbing walls and wasn't sure how serious it was. San Jose's dry summer season followed by winter atmospheric river storms creates a seasonal expansion-contraction cycle in the South Bay's clay-heavy soil that stresses aging interior supply lines, particularly in homes built before the mid-1970s. What could have meant a much bigger job instead only needed one targeted repair.

Water service in San Jose is provided by San Jose Water Company, 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.
“We had slow drains for weeks and figured it was just old pipes. Camera inspection showed root intrusion about 30 feet out. Clear video, clear explanation, no surprises.”
“Solid, professional service. Arrived within the scheduled window and walked me through the sewer camera footage on the spot so I understood exactly what was going on.”
“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.”
