Los Angeles County
Pomona's historic downtown, once a major citrus-packing hub for the region, still has Art Deco-era commercial buildings and residential neighborhoods dating to the city's early-20th-century growth, while areas like Phillips Ranch near the city's eastern edge reflect much more recent development. Home to the LA County Fairplex and Cal Poly Pomona, the city's mix of historic core and newer suburban growth shapes how we approach leak calls here.
The Castillo Family, who lives in Ganesha Hills, Pomona, reached out after noticing a faint hissing sound near the meter box. Pomona's historic downtown, once a major regional citrus-packing hub, has some of the city's oldest plumbing, distinctly older than the newer Phillips Ranch development near the eastern edge. What looked like it might mean tearing out a whole room turned into a same-day, targeted fix once the exact spot was confirmed.

“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.”
