Your home's electrical panel is the heart of its power system. If your lights are flickering, breakers are tripping, or you're planning to add new appliances, it might be time for an upgrade.
Older homes often feature panels that cannot accommodate modern electrical demands. We offer thorough evaluations and expert panel upgrades that improve safety, increase capacity, and reduce the risk of electrical fires or outages—including all permitting, code compliance, and cleanup.

If your home still has an older 60-amp or 100-amp service, if you frequently experience tripped breakers, or if you are planning to install major appliances like an EV charger or heat pump, an evaluation can determine if a panel upgrade is recommended to handle the increased electrical load.
The process typically includes evaluating your current electrical load, coordinating with the local utility company to disconnect power, removing the old equipment, installing the new panel and grounding systems, and completing a final inspection to ensure the installation meets current electrical codes.
Yes, replacing or upgrading a main electrical panel requires a permit from the city or county building department. Our team handles the necessary permit applications and coordinates the required inspections to ensure the work is fully compliant and safe.
While the physical installation of a new electrical panel usually takes one full day, the overall timeline depends on securing city permits and scheduling the utility company to disconnect and reconnect power. We work closely with inspectors and utilities to minimize the time your home is without electricity.
Upgrading an older or undersized electrical panel ensures your property meets current safety standards and can support modern electrical demands, which is often an attractive feature for potential buyers and may help prevent issues during home inspections.
