Contra Costa County
El Cerrito grew up along the original Southern Pacific rail line in the early 1900s, and its hillside neighborhoods, with BART access since the 1970s, sit atop the same Hayward Fault system that runs through neighboring Berkeley and Richmond.
The Nakamura Family in El Cerrito Hills, El Cerrito noticed a water bill that had crept up for two billing cycles with no clear reason and wasn't sure how serious it was. El Cerrito sits along the same Hayward Fault system that runs through neighboring Berkeley and Richmond, a genuine factor in how buried lines and slab foundations shift here. The leak was marked in that same visit, and the repair crew only had to open a small section instead of the whole area.

“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.”
