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 Upgrades & Troubleshooting FAQs
Can you add circuits for new equipment?
Yes. We size circuits for new loads, lighting, and tenant improvements and confirm the panel can carry them.
Do you troubleshoot flickering or nuisance trips in a shop?
Yes. We diagnose overloaded or failing circuits and quote the repair before we start.
Will a tenant buildout need a permit?
Most new commercial circuits do. We pull permits and meet inspections.
Can you work around business hours?
When downtime matters, we schedule around your operations.
Do you also replace commercial panels?
Yes. See our commercial panel replacement page if the service itself is the limit.
