How much does a panel upgrade cost in Foster City?

A 200-amp panel upgrade in the Foster City area costs $1,800–$4,500 depending on complexity. A straightforward panel swap averages $2,500–$3,500. If your meter base also needs replacement or the utility requires a riser upgrade, expect $3,500–$4,500.

Do I need a panel upgrade for an EV charger?

Most Level 2 EV chargers require a dedicated 50-amp circuit. If your panel is 100 amps or less, you'll likely need an upgrade to 200 amps. Many Foster City homes built before 2000 have undersized panels. We can assess your capacity and handle the full upgrade plus charger installation.

How much does EV charger installation cost?

EV charger installation in Foster City costs $500–$2,500 for labor, depending on the distance from your panel to the charger location and whether a panel upgrade is needed. A simple installation with the panel in the garage averages $500–$800.

Do I need a panel upgrade for an EV charger?

If your home has a 200-amp panel with available capacity, usually not. However, many Foster City homes have 100-amp panels that can't safely support a 50-amp EV circuit on top of existing loads. We assess your panel before quoting.

How much does it cost to rewire a house in Foster City?

Whole-house rewiring in Foster City costs $8,000–$25,000 depending on home size, accessibility, and whether walls need to be opened. A typical 1,500 sq ft home averages $10,000–$15,000. Homes with easy attic/crawlspace access cost less than those requiring extensive wall work.

How long does rewiring take?

A full rewire takes 5–10 days for an average Foster City home. You can typically remain in the home during the work, though power to certain areas will be off at times. Drywall patching and painting after the electrical work adds 1–3 days.

Sepanta Electric – Exceptional Full House Rewire I hired Sepanta Electric for a complete home electrical rewire, and the experience exceeded expectations from start to finish. Ben was a pleasure to work with — patient, communicative, and flexible through multiple change orders without ever making the process feel complicated. The scope of work was extensive: upgrading the main panel from 100A to 200A, installing 2 subpanels, and connecting a 28.8kW electric water heater. Despite the complexity, the project came in on time and on budget with zero delays. What really sets Ben apart is that he works hands-on alongside his team during the electrical work — a rarity that translates directly into savings for the customer and tighter quality control. After getting 6 competing quotes, Sepanta came in at a fair price without cutting corners. Highly recommend Ben and the Sepanta Electric team for any project, big or small.

Ben at Sepanta has been my "go-to" electrician for the past 6-7 years. He has done quite a few projects for me.....installed recessed lighting, installed a hard-wired fan, installed outdoor flood lighting, installed numerous outlets, etc etc. He is skilled, honest, and a nice guy.

The Sepanta team did a great job rewiring my florescent lighting to convert it to direct-wire LED tubes. They were quick, responsive, communicated clearly, and delivered exactly what I asked for. Ben helped talk through the different options and gave me a good price for what we settled on. I would definitely recommend them to anyone looking for electrical work.
