Electrical Panel Replacement Process

Here's How We Handle Your Upgrade

We start with a complete assessment of your current electrical panel and your home’s power needs. This tells us exactly what size panel you need and identifies any additional electrical issues that should be addressed during the upgrade.

Next, we coordinate with PG&E to safely disconnect power, remove your old panel, and install the new one. We handle all the permit applications and ensure everything meets current California electrical codes. The new panel gets properly grounded, labeled, and tested before we restore power.

After installation, we walk you through your new electrical panel, explain how it works, and provide you with all documentation for your records. The entire process typically takes one day, and you’ll have reliable, safe electrical service that can handle your home’s demands.

Complete Electrical Panel Upgrade Service

What's Included in Your Panel Replacement

Your electrical panel replacement includes removing the old panel, installing a new panel sized for your home’s needs, updating all connections to current code standards, and proper labeling of all circuits. We handle the permit process and coordinate with PG&E for power disconnection and reconnection.

Many San Mateo homes we work on have panels from the 1970s and 80s that simply can’t handle today’s electrical loads. We see this especially in the Laurel and Highlands neighborhoods where older homes are being updated. These outdated panels create safety risks and limit what you can do with your electrical system.

We also upgrade the grounding system, install GFCI protection where required, and ensure your new panel has room for future expansion. Everything comes with manufacturer warranties, and our work is backed by our service guarantee.

How do I know if my electrical panel needs to be replaced?

If your breakers trip frequently, you smell burning odors near the panel, see scorch marks or rust, or have an older panel with fuses instead of breakers, it’s time for replacement. Panels over 25 years old, especially Federal Pacific or Zinsco brands, should be replaced due to known safety issues. If you’re adding major appliances or your home inspector flagged electrical concerns, replacement is typically the best solution rather than trying to patch an outdated system.

How long does electrical panel replacement take in San Mateo?

Most electrical panel replacements take 4-8 hours to complete, usually finished in one day. The timeline depends on your current setup and any additional electrical work needed. We coordinate with PG&E for power disconnection, which can add time depending on their schedule. Complex jobs involving meter relocation or extensive rewiring may take longer. We’ll give you a realistic timeline upfront and keep you informed throughout the process so you can plan accordingly.

Do I need permits for electrical panel replacement in San Mateo?

Yes, electrical panel replacement requires permits from the City of San Mateo. We handle all permit applications as part of our service—you don’t need to deal with the paperwork. The work must be inspected by city officials to ensure it meets current electrical codes. This protects you and ensures your insurance coverage remains valid. Attempting panel replacement without permits can create serious problems when you sell your home or file insurance claims.

What size electrical panel do I need for my San Mateo home?

Most modern homes need at least a 200-amp electrical panel to handle current electrical demands. Smaller homes might work with 150-amp panels, while larger homes or those with electric vehicle charging, pools, or extensive electrical systems may need more capacity. We calculate your home’s electrical load based on square footage, appliances, HVAC systems, and planned additions. The goal is ensuring you have enough capacity now and room for future electrical needs without oversizing unnecessarily.

How much does electrical panel replacement cost in San Mateo?

Electrical panel replacement typically costs between $2,000-$4,000 in San Mateo, depending on panel size, complexity of installation, and any additional electrical work needed. Factors affecting cost include accessibility of your current panel, whether the meter needs relocation, permit fees, and PG&E coordination requirements. We provide upfront pricing after assessing your specific situation. While it’s a significant investment, it’s essential for safety and often required for insurance coverage and home sales.

Will my power be off during the entire electrical panel replacement?

Your power will be off for most of the installation process, typically 4-8 hours. We coordinate with PG&E for disconnection and reconnection to minimize inconvenience. We recommend planning for the day without electricity—charge devices beforehand, have flashlights ready, and consider arrangements if you work from home. Some electricians use temporary power setups for essential circuits, but complete disconnection is usually necessary for safety. We’ll give you advance notice of exactly when power will be off so you can prepare.
