Sampson Electric upgraded our electrical box for our generator, and we couldn’t be more impressed with their service. From the initial consultation to the final installation, the team was incredible! They communicated clearly about the timeline and costs. They were true professionals, taking the time to explain the process, ensuring everything met code, and leaving the work area spotless. The upgrade has given us peace of mind during power outages, and the quality of their work can’t be beat! We highly recommend Sampson Electric!

Mike and his team are professional and great to work with. We installed a heating unit in our garage and had Sampson Electric do the electrical work. I was able to promptly schedule an estimate with Mike. After completing the estimate Mike was able to schedule his employees to get the work done the same day. The final cost was in line with the estimate. All around great customer service!
