Whole House Surge Protection across San Francisco and San Francisco County

Bay Area households are adding load quickly: EV chargers, heat pump water heaters, induction ranges and home batteries. Older 100-amp panels in San Francisco often can't absorb that without a load calculation and, sometimes, an upgrade. Wind-driven safety shutoffs in the hills also make backup power a common request.

In San Francisco we regularly work in the Castro, Nob Hill, the Mission District, the Sunset, the Richmond and Noe Valley. Our whole house surge protection service also covers nearby Daly City, Brisbane, Sausalito, South San Francisco, Belvedere Tiburon and Alameda. ZIP codes served in San Francisco include 94114, 94115, 94116, 94117, 94118, 94119, 94120, 94121, 94122, 94123 and more.

What affects whole house surge protection pricing in San Francisco

Whole house surge protection cost in San Francisco is modest compared with the equipment it protects. The price depends on the device rating and whether the panel has a spare two-pole breaker space. Most installations take about an hour, and it's often added during a panel upgrade for little extra labor.

Whole House Surge Protection questions from San Francisco customers

Is surge protection required by code?

Current electrical code calls for a surge protective device when a home's service equipment is installed or replaced. It's also a sensible add-on to an existing panel.

How long does a surge protector last?

Good devices last years, but each surge wears them a little. Most have an indicator light, and we check it during any service visit in San Francisco.

Can you install one during a panel upgrade?

Yes, and it's the ideal time. See electrical panel upgrades and, for outage planning, generator installation.

Don't power strips already protect my electronics?

They help with what's plugged into them, but they do nothing for hardwired equipment like air conditioners, ovens and furnaces. A panel-mounted device protects every circuit, and the two work best together.

What customers say

After two long outages we had a standby generator put in. They sized it properly instead of pushing the biggest unit, and showed us how the transfer switch works.
Rob H.Standby generator

After a surge took out our garage door opener and a TV, they installed a whole house protector at the panel. Quick job, clear price, no upsell.
Grace N.Surge protection

We needed new circuits and lighting before opening our shop. Bayshore worked around our contractor's schedule and the inspection passed the first time.
