Frequently asked questions

Anything special about fixture work in San Mateo's housing stock?

San Mateo is built largely between the 1920s and 1950s: prewar and early-postwar neighborhoods under mature trees, plus newer bayfront condos. In the older homes, original shutoff valves and supply lines are often the real job hiding behind a faucet swap — replacing them while the water is off is cheap insurance.

Do I need a water softener in San Mateo?

Probably not — San Mateo receives Hetch Hetchy supply — soft, which is gentle on tanks, fixtures and appliances. That is unusual for California. Maintenance still pays (anode rods, valve checks), but the aggressive descaling schedules needed in hard-water regions can relax here.

Why is my water flow weak at one faucet?

Usually a scaled-up aerator (unscrew and soak in vinegar) or a clogged cartridge — both minutes to fix. Weak flow at several fixtures points to bigger issues: pressure regulator, partially closed valve, or corroded galvanized pipe.
