Electrical panel upgrade in San Mateo, CA

If your San Mateo home still has a fuse box, a Zinsco or Federal Pacific panel, or a breaker box with double-tapped lugs and no free slots, an upgrade is the single highest-value electrical project you can do. It is also the prerequisite for almost every other upgrade in San Mateo County homes.

What affects panel upgrade pricing in San Mateo

Service size and panel location	A straight swap in the same spot costs far less than relocating the service.
Meter and mast condition	Rusted masts, buried service and damaged meter bases add work at the utility side.
Grounding and bonding	Older homes often need ground rods and a proper water bond added.
Permit and utility coordination	Included in the quote, but the schedule depends on the local inspector and utility.

Recent San Mateo feedback

Panel had no room left and we wanted an EV charger. Got a straight answer, a flat number, and the whole thing done in a day. The new labels alone were worth it.

Marisol R.San Mateo, CA

Added four outlets and GFCI protection in the garage and laundry. Small job, treated like a real one. Fair price, no upsell.

Lorraine T.San Mateo, CA

Generator sized properly, transfer switch installed, and they tested it under load. Ran the whole house through the last shutoff without us touching anything.

Electrical Panel Upgrade in San Mateo — questions we get asked

Do I really need 200 amps?

If you are adding EV charging, electric heat, a hot tub or an ADU, yes — and it is far cheaper to do it once. If your loads are modest and the panel is simply old, a same-size replacement may be all you need. We tell you which case you are in.

Do I need a permit for a panel upgrade in San Mateo?

Panel and service work is permitted work in California. We pull it, meet the inspector, and handle the utility coordination so the job closes out properly.

How much does an electrical panel upgrade cost in San Mateo?

In San Mateo and the wider San Mateo County market, a straightforward 200 amp upgrade usually lands in the low-to-mid four figures, with meter relocation, long service runs and mast work pushing it higher. You get one flat number after we look at the service entrance, not a range.

Will you fix the labeling?

Every panel we touch leaves with each breaker mapped and labeled. It takes twenty minutes and saves the next electrician an hour.

How long does a panel upgrade take?

Most San Mateo residential upgrades are a one-day job. Power is off for part of that day while the utility disconnects and reconnects, and we schedule that window with you in advance.
