"Matt Carr has worked on many projects for my investment properties and he has always charged a fair price and has performed in a professional manner while completing the task on schedule in accordance with applicable codes and local standards. As a professional engineer myself I would recommend Matt to perform electrical work for your home and or facility. I am available as a reference for Matt Carr."

Peter J. Barbadoro P.E.

"Matt recently installed some light fixtures in my condo and did a fantastic job. He is extremely detailed with the work he does and is a true professional. He was very quick to follow up when I contacted him for an initial quote and was very punctual, arriving right on time on the day we specified. The quality of his work was outstanding and he made great suggestions on installing lighting in my home. I would highly recommend the quality of his work and would recommend him as a truly professional electrician."

Curt Houghton

"I would highly recommend using MJ Carr Electrical Services for any electrical work that you may need. We have utilized Matt on several occasions and have been nothing but pleased with his work. The jobs Matt has taken on range from large (complete rewiring of a finished basement) to smaller (installing a flat panel television). In all cases, Matt's work was exemplary. He met with us prior to review the work being requested and presented a fair, written estimate. Matt was in constant communication (email, calls, text messages) with us as far as dates and times, and working out some of the logistical details. And.....he was always on time."

Michael and Jennifer Lavoie, Weymouth, MA

"Matt was a referral from a friend, and by far it was the greatest referral! I am always thinking of projects that we need done so I can call on Matt! From the first time Matt came to our house he has been on time, professional and knowledgeable on every front.He has never steered us wrong in our electrical needs and listens to what we want. If I can’t be home I am so comfortable with Matt being in my house and completing the job at task. Matt has been such a good find, we couldn't be happier! " 

Aimee Barnes

"Matt Carr is not only professional and fair he always comes prepared, is flexible, responsive and friendly. I recommend him highly and wish him continued success."
