Ken Marquis Electric is a Nashua, New Hampshire electrician, and a recent customer who had just moved in says Ken rewired some faulty outlets and three-way switches and went out of his way to help get things situated. The company describes itself as a residential and commercial electrical contractor offering service upgrades, whole-house electrical work, generator hookups, EV charger installation, troubleshooting and specialty circuits, and its website cites NH electrical license number 11910M. A recent reviewer said Ken took the time to explain what he was doing, was accommodating when they asked for an extra switch, light or outlet, and is now their go-to electrician. A recent customer who has used Ken Marquis for home projects for two years wrote that Ken knows how to keep his customers informed throughout the project. In a 2024 review, a customer said Ken assessed their electrical needs for a remodeling project and thought through the location of light switches and the order of the switches on each. A 2024 reviewer said Ken had been the go-to electrician for that reviewer's general contracting business and home for almost a decade.
I highly recommend Ken. He was contracted to do electrical work for us and he was terrific. So much so, he’s now our go to electrician. He was cordial, pleasant to work with, no question was stupid, he took the time to explain what he was doing. And the best of all … he was so accommodating when we asked for an extra switch, light, or outlet. He once told me … no matter what work he’s doing, he does it as if he were doing it for himself.

Ken did a great job rewiring some faulty outlets and three-way switches in my house. He is very thorough and professional. He followed up with me quickly and got the job done in record time. He went out of his way to help me get things situated as I had just moved in to my home. I really appreciate his promptness, professionalism, and friendly, helpful attitude throughout the time he worked on my home. I highly recommend his service.

Ken Marquis is an outstanding electrician. Thoughtfully and creatively, he assessed our electrical needs and implemented elegant solutions. Ken is knowledgeable, conscientious, and thorough. We especially appreciated his thoughts about the location of light switches and the order of the switches on each, making for sensible and efficient access to lighting upon entering and leaving each room. It was a pleasure working with him. Thank you, Ken, for contributing significantly to our remodeling project.
