Ken Marquis Electric is an electrical contractor in Nashua whose customers describe him as a go-to electrician for home projects and general contracting work. His website says he handles troubleshooting, installations, and upgrades for homeowners and small businesses. Recent Google reviews describe rewiring faulty outlets and three-way switches, prompt follow-up, and careful work that helped a homeowner settle into a new house. Another customer, writing in June 2026, said Ken had handled home projects for two years using high-quality parts while keeping communication clear. Older reviews add useful context: in June 2024, a homeowner praised his thoughtful planning of switch locations during a remodeling project, and an April 2024 customer said Ken had been their go-to electrician for almost a decade. Those customers emphasized workmanship, attention to detail, and professionalism. Ken appears suited to homeowners and small businesses seeking electrical troubleshooting, rewiring, outlet and switch work, and installation planning. Ask for a written scope and confirm the details of the specific project before scheduling.
“Safe, reliable electrical services for homeowners and small businesses. From troubleshooting to installations and upgrades, we’re ready to help.”
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.
We have been using Ken Marquis for our home projects for two years now. The work is exceptional with high quality parts. Communication is key in all successful businesses and Ken knows how to keep his customers informed throughout the project.
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.
Ken has been my go-to electrician for my general contracting business and home for almost a decade. His attention to detail and his level of workmanship is simply unrivaled. I have complete faith that he will get the job done correctly and maintain the highest level of professionalism on my jobs. He is also an exceptionally cautious driver.
