What We Offer
Main Panel Replacement
We replace outdated, damaged, or undersized commercial panels with modern, high-capacity panels from trusted manufacturers. This ensures your business has a safe, reliable foundation for all electrical operations.
Service Upgrades
Need more power? We upgrade your electrical service to higher amperage — from 200A to 400A, 600A, or higher — to support expanded operations, new equipment, and growing power demands.
Sub-Panel Installation
Adding a new section, tenant space, or equipment area? We install sub-panels to extend your electrical capacity to exactly where it's needed without overhauling your entire system.
Code Compliance Updates
We bring your commercial electrical system into full compliance with current NEC and local codes. Our commercial troubleshooting service can identify and resolve any violations.

What our customers say
Lucas Bernacki
August 2026
Josh (and Charlie) provided excellent service. We called for a site visit and an estimate. They got us on the schedule within a week, showed up on time, offered a fair price, and were able to complete the work the same day! After they replaced the electrical panel, they took the time to work with me to test and clearly label each switch.
Bret Barker

Josh was professional through and through. He responded quickly, came out to assess my new circuit installation needs and discussed options, clearly listening to my concerns. He then gave me an upfront estimate and got it all done same day. The new run is tidy, he cleaned up thoroughly, and was overall great to work with.

Josh has done two projects for us, including troubleshooting some non-working outlets and installing a new bathroom fan. He’s extremely courteous, professional, reliable, and offers fair pricing. Highly recommend for any electrical needs!
Commercial Panel Replacements FAQs
How do you limit business downtime?
We plan the cutover, stage the new gear, and schedule the utility disconnect for the shortest outage we can.
Do commercial panels need a permit?
Yes. Service and panel replacements need permits, inspection, and often utility coordination.
Can you upgrade service for new equipment?
Yes. We size the service to the new load and quote the panel, feeders, and any required disconnects.
What are signs a commercial panel is undersized?
Frequent trips, a warm enclosure, no spare slots, or new equipment that the existing service cannot carry.
Do you also handle emergency commercial repairs?
Yes. If the panel is already failing, we stabilize first and quote the replacement.
