Situations we see in Martinez
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.
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.
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 Martinez jobs.
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 Contra Costa County
Breaker tripped Sunday night and I got a call back in about ten minutes. Tech found a bad connection in a junction box behind the closet, fixed it that night, and the price was what he said on the phone.

How much does an electrical panel upgrade cost in Martinez?
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.
Do I need a permit for a panel upgrade in Martinez?
Yes, service work is permitted and inspected. We pull the permit, schedule the inspection and meet the inspector so you don't have to.
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.
