Santa Clara County
Sunnyvale sits at the heart of what was once called the Valley of Heart's Delight, the fruit-orchard economy that defined the Santa Clara Valley before the tech industry transformed it into Silicon Valley, and pockets of that older agricultural-era housing still exist in neighborhoods like Old Town Sunnyvale alongside decades of subsequent tech-driven residential growth. That layered history means construction era varies significantly across the city.
The Lindqvist Family, who lives in Old Town Sunnyvale, Sunnyvale, reached out after noticing a damp patch on the wall that never fully dried out. Sunnyvale's Old Town district predates the tech industry's transformation of the valley, carrying plumbing from the area's earlier fruit-orchard economy, distinct from the newer construction found throughout most of the city. A problem that had been dragging on for months was pinpointed in under two hours.

“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.”
