Your home’s electrical panel is the heart of your electrical system—responsible for safely distributing power to lights, outlets, appliances, and every other part of your home. At Site Electric Services, we specialize in safe, code-compliant electrical panel upgrades, subpanel installations, and full main panel replacements throughout Vallejo, Benicia, Napa, Fairfield, Concord, and surrounding North Bay communities.
Whether you’re experiencing frequent breaker trips, planning a remodel, or simply need to bring your system up to current code, our licensed electricians are here to guide you through the process—from permitting to final inspection.
Many older homes in the Bay Area still rely on outdated 60 or 100 amp service panels, some of which may be overloaded or even unsafe. An electrical panel upgrade increases your system’s capacity, improves safety, and allows you to support new technology like:
If your existing panel is more than 30 years old, you may be at risk of hidden fire hazards, especially if your home still has a Federal Pacific Electric (FPE), Zinsco, or Pushmatic panel—many of which are now known to fail under overload conditions.
Not sure if your panel is up to the task? Here are some common red flags:
If any of these apply to your situation, it may be time to consider upgrading.
At Site Electric Services, we take pride in making the panel replacement process smooth, transparent, and hassle-free. We handle everything—so you don’t have to worry about permits, code violations, or dealing with the power company.
We start with a site visit to inspect your existing panel, service entrance, and grounding system. We'll review your power usage, any planned upgrades, and identify your utility provider’s requirements. From there, we’ll provide a detailed, no-obligation quote outlining your options.
We obtain all required permits from your local building department and submit any necessary service upgrade applications to your utility provider, whether it's PG&E, City of Napa Utilities, or another provider. Our team handles the drawings, photos, and load calculations required for approval.
For main panel replacements, the utility will need to shut off power to your home. We coordinate this with their scheduling department and typically perform the changeover in a single day, minimizing downtime. For subpanels, no utility shutdown is needed.
On the day of your install, our licensed electricians:
We use top-rated equipment from manufacturers like Square D, Eaton, and Siemens—ensuring you get reliable, high-quality components that last.
After installation, we schedule the required building inspection, and the utility company comes out to re-energize your meter. We stay on-site to confirm everything is up and running—and your home is safe, compliant, and fully powered.
A subpanel is a smaller distribution panel that connects to your main panel and feeds power to a specific area—like a garage, workshop, ADU, or addition.
Subpanels are ideal when:
We install subpanels that are fully grounded, labeled, and expandable. Whether you’re running a 60 amp panel to your backyard office or a 100 amp panel for a new in-law unit, we’ll make sure it’s installed right the first time.
We offer fair and competitive pricing based on the size of your system, level of access, and site complexity. Every panel installation is quoted individually after a site visit, but here are some average costs to help you budget:
