Why San Lorenzo homes call us at night
Most of San Lorenzo Village was built in the years right after World War II. Many of those homes still run on their first water lines and first drain lines. Pipes that age tend to fail without much warning: a supply line splits under the house, a drain that was slow for months stops for good, or an old shutoff valve will not close when you need it to.
The calls we get from the 94580 ZIP at night are mostly three things. Water coming through a ceiling or out from under a wall. Sewage backing up into a tub or shower because the main line is blocked. A water heater that has started to leak in the garage. All three are core plumbing work for us.
What happens when you call
We answer the phone, day or night. Tell us your street, what is leaking or backing up, and whether the water is still running. We send a plumber and give you an arrival window. San Lorenzo sits right between Hesperian Boulevard and I-880, a short drive from our Hayward base, so it is one of the fastest places for us to reach.
When the plumber gets there, the first job is to stop the damage. After that we show you what failed, explain the repair and go over the cost before any more work starts. You decide what happens next.
Sewer backups and the Oro Loma district
San Lorenzo is unincorporated, and its sewer mains belong to the Oro Loma Sanitary District. The pipe from your house to that main, called the lateral, is the owner's to keep up. When sewage comes up in the lowest drain of the house, the blockage is usually in that lateral. We clear it, and when a line keeps clogging we can run a sewer camera through it so you can see the cause. Our San Lorenzo drain cleaning page has more on that work.
