Pinpoint concealed foundation slab leaks, pressurized water line breaks, and hidden in-wall moisture without destructive digging. We combine acoustic frequency ground microphones, thermal infrared imaging, and helium tracer gas diagnostics across the SF Peninsula.
Unexplained spikes in your municipal water bill, damp spots along baseboards, warm patches on hardwood or tile, and the faint sound of running water when all taps are closed are classic hallmarks of a hidden pressurization leak. In older Peninsula homes—particularly mid-century slab-on-grade foundations and Eichler homes with copper radiant heating loops embedded directly in structural concrete—unaddressed leaks cause foundation settling, mold blooms, and costly structural damage.
Traditional plumbing approaches often involve jackhammering floor slabs or punching holes through finished drywall just to locate a suspected break. Daso Plumbing utilizes advanced electronic leak detection technology that isolates the exact failure point to within inches before a single tool touches your property. By pressurizing lines and deploying high-frequency acoustic ground microphones and precision thermal imaging cameras, we trace concealed water pathways through solid concrete, tile, and earth without disruption.
Once the leak is pinpointed, our licensed C-36 plumbers present you with clear, engineered repair options. Depending on your home's age and plumbing layout, choices include targeted single-tile spot repairs beneath the slab, or an overhead non-invasive PEX-a reroute through attic or crawlspace framing that permanently abandons compromised sub-slab lines. We document all acoustic and pressure readings in a detailed diagnostic report suitable for homeowner insurance claims.
High-gain ground microphones and electronic listening discs amplify the subterranean hiss of water escaping pressurized lines through concrete slabs.
High-resolution radiometric thermal cameras detect temperature anomalies across radiant floor heating loops, concrete slabs, and concealed wall cavities.
Nitrogen and helium tracer gas isolation tests pressurize isolated plumbing segments to detect microscopic micro-fissures undetectable by standard gauges.
When aging under-slab copper is severely corroded, we engineer clean overhead reroutes through attic rafters or crawlspaces, permanently abandoning vulnerable slab pipes.
Whole-home smart flow-monitoring shutoff valves that continuously evaluate water flow down to fractions of an ounce per minute and shut off automatically during failures.
We provide comprehensive, itemized diagnostic documentation, acoustic log readouts, and photo records tailored for Bay Area property insurance adjusters.
