Report
Unreliable and untrustworthy. I had a 4:00 pm appointment with Mike for an estimate. I needed to leave work early to meet him. I confirmed the 4pm appointment at 3:00 pm. When he did not show by 4:20, I called and it was sent to voicemail after 2 rings. I then got a text from Mike that he needed to stop by another job, which apparently he was not going to mention to me since I had not heard from him at 4:20.
When he did not show by 5:20 pm, I told Mike to forget the appointment. He never even bothered to respond or apologize. I have attached a screenshot of the text messages. This is precisely the type of contractor you want to avoid.

Mike has done very nice work for my mother, mother-in-law and sister-in-law. The work done has included CAC connection, generator transfer switch installations and full fuse to breaker upgrades. All his work has been top notch, done neatly and at a reasonable price. He does the work when he says he will and communicates with you like he should. I am a home inspector myself and I am very happy with the work I have seen him do and will continue to refer Mike of MS Electric to my family and friends as well as use him myself in the future when needed.

A couple of months ago my electric panel began to arc. Having moved in to my home less than a year ago, I knew of no electricians in the area. I placed a request through Home Advisor about 10pm on a Saturday, and Mike from MS electric responded within the hour. He stopped in the following Monday, removed two bad circuit breakers, and set up to have the panel replaced. Since then he returned, did the job in under 4 hours, was efficient, courteous, knowledgeable and professional. Excellent communication throughout. Highly recommended!
