I contracted Electrica to upgrade my main service panel and install a NEMA 14-50 to charge my EV. Not only was Nick able to help me through the process, but he also provided very quick turnaround for the jobs. I was never left waiting for his team, as they were always ready to work on my house the moment that PG&E moved the process forward. Thank you for your professionalism and speed!

Nick and Andrew did a great job upgrading my electrical panel and adding a new EV charger. The work was completed in two days at a fair price. Very professional, arrived on time and understood everything that needed to be done. This is a very easy company to work with and I would definately hire them again to work at my home. (July 2025)

Great service, had a different company install a my main breaker box as well as install a generator transfer switch. Well needless to say is they did a horrible job. Called the good people at Electrica to inspect. The came inspected the work and explained to me in simple terms what was don't correctly and incorrectly. Quoted me on the spot for repairs and got to work. Quality was above and beyond what I expected, everything is working the way it should. Not to mention reasonable pricing, I will using Electrica for all my electrical needs from now on.

Great experience working with Nick and his team to upgrade our outdoor electrical panel for solar service. Nick kept me in the loop through every stage, with timely text updates...

Electrica installed an EV charger. Did a great job. They re-worked the main panel a bit to accommodate the breaker, cleanly/neatly ran metal conduit to the front of the house and installed a smaller breaker box and the charger inside the garage...

I found them on Yelp and they truly exceeded my expectations. I needed a Tesla Charger installed, but my meter capacity was low. Their team handled the job flawlessly and ensured everything was done up to code. They are knowledgeable, efficient, and highly professional. I would strongly recommend them for any electrical services.

I needed to wire and install a 240v hanging power heater. We needed to have new switches from our main breaker to the backyard. They did the work on-time and at a fair price. We will use them for all of our electrical needs in the future.

I had an excellent experience with Electrica installing a Tesla Universal Wall Charger in an older house with only 100amp service. Nick responded very quickly with an estimate that was very reasonable compared to others. Andrew did the work, replacing my old 100amp service breaker, installing the Tesla/Neurio load balancer (required because of the low 100amp house service), new 60amp sub-panel, and the EV wall charger. Nick also handled the permit with Santa Clara County which took a few days but worked out well.

Does your home need rewiring?
- Your insurance company or a home inspector flagged knob-and-tube or aluminum wiring
- Most outlets are two-prong, with no ground wire
- Breakers trip often, or lights flicker and dim
- Outlets or switch plates feel warm, or you notice a burning smell
- The house was built before the mid-1970s and the wiring was never updated
- You plan to add an EV charger, a heat pump, or an induction range
Not sure what's behind your walls? The on-site estimate is free, we will tell you straight.
If you smell burning, turn off that breaker and call us.
Insurance company flagged your wiring?
Many insurance companies in the Bay Area now refuse to cover or renew homes with knob-and-tube wiring, and some want an electrician to check aluminum wiring before they insure the home. The same thing comes up in home inspections when you buy or sell. We replace the old wiring and close out the permit with the city, so you have the final inspection sign-off to show your insurer or buyer.
What we replace
Knob-and-tube wiring
Common in Bay Area homes built before the 1950s. The insulation dries out and cracks with age, and there is no ground wire. We disconnect it and run new copper circuits.
Aluminum branch wiring
Used in many homes built from the mid-1960s to the mid-1970s. Aluminum expands and loosens at the connections over the years, which can overheat outlets and switches. We replace it with copper.
Ungrounded two-prong circuits
Without a ground wire, a surge protector can't do its job, and a three-prong outlet is only for show. We run new grounded circuits, so your outlets are grounded for real.
Old cloth-covered wiring
Rubber and cloth insulation from the 1940s to the early 1960s gets brittle with age. We replace it before it cracks inside the walls.
Kitchen, laundry, and bathroom circuits
Older homes often run the whole kitchen on one or two circuits. We add dedicated circuits, with GFCI and AFCI protection where code requires it.
The whole house or just part of it
Sometimes the whole house needs new wiring, sometimes only a few rooms do. You can also choose the scope: the outlets only, or the outlets and the lighting. We will recommend what makes sense for your home.

Planning an EV charger or a heat pump?
If you're rewiring anyway, it's the best time to add circuits for an EV charger, a heat pump, or an induction range. We plan the new wiring around what you want to add, so you don't have to open the walls twice. We have installed 500+ EV chargers across the Bay Area, so we know what these loads need.
