Situations we see in Menlo Park
Panel is rusted or wet
Water in an enclosure corrodes bus stabs and creates high-resistance connections. Once rust reaches the bus, the panel is done.
Zinsco or Federal Pacific panel
These breakers have a documented history of failing to trip under fault. Replacement is the only real remedy, and it is one of our most common Menlo Park jobs.
No space left in the panel
Double-tapped breakers and tandem cheaters are a sign the panel is full. A 200 amp replacement gives you 40 or more spaces and room for the next ten years.
Adding an EV, heat pump or ADU
All of these need a load calculation. If existing demand plus the new load exceeds your service, the upgrade comes first.

Reviews from San Mateo County
Kitchen breaker kept popping whenever we ran the microwave and kettle. They put in a dedicated circuit instead of just telling us to use one appliance at a time.
Alicia G.Dedicated circuit · Menlo ParkZinsco panel replaced. Straight quote, one day of work, and they handled the utility disconnect scheduling so I didn't have to call anyone.
Yasmin K.Panel replacement · Menlo ParkWe needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.
Priya N.Panel upgrade · Menlo ParkElectrical Panel Upgrade in Menlo Park — questions
Can you replace just the breakers instead of the whole panel?
Sometimes. On a sound modern panel, breaker replacement is fine. On a Zinsco, Federal Pacific or corroded enclosure, new breakers don't fix the bus, so the panel gets replaced.
Do I need a permit for a panel upgrade in Menlo Park?
Yes, service work is permitted and inspected. We pull the permit, schedule the inspection and meet the inspector so you don't have to.
How much does an electrical panel upgrade cost in Menlo Park?
Cost tracks the service size, the condition of the service entrance and whether the meter has to move. A straight 100 to 200 amp swap sits well below a job that needs a new mast and underground feed. Call (833) 652-8933 and we will walk your panel and quote a flat number.
How long will my power be off during the upgrade?
Plan on most of a working day. We coordinate the utility disconnect and reconnect so the outage lands in one block rather than spread over days.
Do I really need 200 amps?
If you are adding EV charging, electric heat, a hot tub or an ADU, almost certainly. We run an actual load calculation rather than guessing, and if 100 amps genuinely still works we will tell you.
