San Mateo County
San Mateo's historic downtown core along the Peninsula predates much of the surrounding Bay Area's suburban tech-driven growth, and neighborhoods like Hillsdale reflect a distinct mid-century construction wave from the older core.
The Kowalski Family, who lives in San Mateo Village, San Mateo, reached out after noticing a faint hissing sound near the meter box. San Mateo's historic downtown core has plumbing considerably older than the mid-century Hillsdale district built during the Peninsula's postwar suburban boom. The diagnostic report was enough to move the insurance claim forward without further back-and-forth.

“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.”
“Good experience overall, technician was knowledgeable and thorough. Took a little longer than expected but they were clearly being careful about pinpointing the exact spot before marking it.”
“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”
“Ground near our garage had been soft for a while. Turned out to be the main line. They marked the exact dig spot and our plumber only had to open a two-foot section instead of the whole path.”
