Yes, Portola Valley is part of our regular Bay Area service area. We’re out in the area regularly for both installations and repair calls, handling tank and heat pump water heaters alike. Call (408) 733-2000 to schedule a free consultation.

Larger properties, especially those with multiple structures like a guest house or pool house, sometimes benefit from more than one water heater rather than trying to serve everything from a single unit. A higher-capacity heat pump water heater can also keep up with heavier household demand while running more efficiently than a comparable tank system. We assess your property’s layout during the free consultation.

Cost depends on the type of unit — standard tank or heat pump — plus your property’s plumbing and electrical setup. Rather than a rough number over the phone, we visit the property in person and provide a clear, itemized quote before scheduling any work.

Banging or knocking noises are usually caused by sediment settled at the bottom of the tank, which traps water and causes it to boil and pop as the unit heats. It tends to get louder over time if the tank isn’t flushed, and can shorten the unit’s lifespan if left unaddressed.

We treat leaks as priority calls since they can cause water damage quickly. Same-day service is usually available if you call earlier in the day. Reach us at (408) 733-2000 and we’ll get a technician headed your way.
