 Trustindex verifies that the original source of the review is Google. The lights in my house started flickering so I called Liberty Electric power Company. They came out and checked the lines from the telephone pole to my house and they said I had an internal problem with my current electrical box which was only rated at 50 amps and it had been installed about 60 years ago. So they immediately turned off my power and would not turn it back on until I had it replaced. So I called Janusz Electric and spoke with Mitch. He was great he came out to my house within the hour, we made a deal and he started immediately with getting me some temporary power until they could come back the next morning to replace my panel and upgrade to a 200 amp. He had three guys there and they worked all day until they got the panel fixed and then he got the inspector out and got it approved so I was up and running . Everything came out great looks perfect and I'm very happy with my new service. The pricing was fair and they were very professional. THANKS Mitch

 Trustindex verifies that the original source of the review is Google. I had a wonderful experience with Janusz electrical.  I had reached out on a Thursday or Friday and was able to get an appointment scheduled for the following Tuesday.  It wasn't an emergency of any kind but we couldn't get some lights on our outdoor posts working.  Mitch was able to determine it was just a bad switch on the outlet (I was thinking it was something significantly worse), was able to swap it out quickly and have us back up and running in no time.  He was extremely professional, kind and the pricing was very fair.  I would highly recommend Janusz Electric.

 Trustindex verifies that the original source of the review is Google. Janusz did great work on a handful of move-in items I needed. Owen and Gabe showed up promptly and got right to work, coordinating tasks so they could work smoothly and efficiently. As they went they were communicative and open to questions and input I had about exactly how I wanted certain things done. The price was reasonable and fair and matched their initial estimate very closely. Highly recommended.
