Expert water and slab leak detection in Kentfield, CA — from Kent Woodlands to the College of Marin flats, found fast and fixed right.
Kentfield sits where the wooded slopes of Mt. Tamalpais drop into the Ross Valley floor, and that mix of terrain is hard on water lines. Hillside homes in Kent Woodlands fight shifting soil and decades-old copper, while the older flats near the College of Marin and Corte Madera Creek deal with high water tables and aging under-slab plumbing. John Owens Services uses electronic and acoustic leak detection to pinpoint the exact spot — no guesswork, no tearing up half a wall or a foundation to find it.
We use electronic acoustic equipment, pressure testing, and thermal imaging to pinpoint the leak to within inches before any digging or cutting. That precision matters on older Kentfield homes and hillside Kent Woodlands lots, where exploratory demolition gets expensive fast.
Yes. Slab leak detection is a core specialty, and it's especially common in the flatter Kentfield and Greenbrae neighborhoods near Corte Madera Creek where homes sit on slab-on-grade foundations. We're licensed (CA #501853) and locate the leak under the concrete without breaking the whole floor.
We do — a hidden water leak only gets more damaging the longer it runs, so we offer same-day service throughout Kentfield and the Ross Valley to find and stop it quickly.
Very likely. An unexplained bill jump usually means a hidden supply-line or slab leak, and our detection equipment can confirm it and find the exact source, often the same day you call.
From the Marin coast to Sonoma wine country, we bring honest plumbing, heating & cooling to homeowners across both counties — based locally since 1986.
