    I have only good things to say about CMC Electric, Inc. This was the second big job they have done for me at my home. Electrician Shawn came to map out and quote what would be needed to most unobtrusively install two new dedicated lines and circuits to power an under-the-sink R/O Water Filter system and dishwasher. Very detail oriented! Electrician Andrew installed the new circuits and power lines. It was terrific working with this gentleman. He was very personable, knowledgeable, and patient in putting up with my many questions. His work was impeccable and his passion for helping clients was sincere.

    The just finished an upgrade in service at my house. It took two days and lots of digging and trenching to get the new mains run.
    Also updated the breaker panel.
    Have to say they did an excellent job. Very professional and worked through the hiccups you would expect in a 60+ year old house.
    Their price to value was excellent. We got our monies worth with them.
    Would highly recommended and plan on using them again in the future.

    I had never used CMC Electric but the reviews were all so positive. I'm happy I did.
    From Brittany setting up everything for me, to Sean as my electrician, it was seamless.
    Sean was nice, professional, and very experienced electrician. He tackled 20 foot ceilings to change my track lights,he removed my old fan and set up my new fan with light. And he took the old fan away for me. He also tackled a closet full of wires and organized them for me.
    Sean also had some really great recommendations about my basement rec room lighting that I'll implement next time.
    In summary, I can wholeheartedly recommend CMC Electric. A great local electric company with great employees.
