Electrical Panel Upgrade in Laguna Niguel, CA

A lot of Laguna Niguel houses are still running the panel they were built with, on a service sized for one window AC and a black-and-white television. Add an EV, a heat pump and an induction range and that panel is out of room and out of capacity.

Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

Situations we see in Laguna Niguel

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 Laguna Niguel 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 Orange County

Hot tub circuit and disconnect. Permit, inspection, everything. Showed up when they said and cleaned up after.

Standby generator install. They sized it to what we actually use rather than the biggest unit, then walked me through the transfer switch and the exercise cycle.

Renee B.Generator · Laguna Niguel

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.

Electrical Panel Upgrade in Laguna Niguel — questions

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.

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.

How much does an electrical panel upgrade cost in Laguna Niguel?

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.

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 Laguna Niguel?

Yes, service work is permitted and inspected. We pull the permit, schedule the inspection and meet the inspector so you don't have to.
