On 1/14/2024 Tony Siebers had this to say:
I called Greg with an "emergency" electrical problem. My lights started to flicker in half the house and then the power went all the way out. Given the cold temperatures I was afraid that my pipes could freeze if it wasn't fixed quickly. Greg came out the same day that I called. Greg diagnosed the problem within the first 5 minutes. He was very knowledgeable and efficient. I would highly recommend him and would rate him higher than 5 stars if I could. Great work and reasonable prices.

On short notice Greg took the time from his busy schedule to troubleshoot an electrical issue I had at my septic tank. I never met this man but kudos to you for diagnosing the problem and your quick response. Definitely 5 stars!
