Derek and his coworker did a great job.
Derek and his coworker did a great job. They found the issue in the upstairs bedroom and fixed it. They also relabeled all of my circuit breakers to the electrical box in my cellar. They also gave me an estimate on replacing my smoke alarms, which are currently defective. They wore foot protection to make sure they didn’t track any dirt into the house. It was a pleasant experience.
Jim Hardacre

Andres Silva
Installed by an honest company
I am beyond grateful for this company. On one of the coldest days of the year, my mother's circuit breaker panel was humming/arcing, lights dimming and flickering, and I was beyond terrified the worst would happen. I reached out, and within 24 hrs, Pam called me, even texted because she knew the severity of my email. (She's SUCH a sweetheart, by the way.)
She called me and I explained everything; she said they typically try to give options because, let's be honest, it's expensive just to breathe nowadays. She scheduled me, and the next day Jake came out, and within 30 min he delivered 3 options. We went with replacing the whole panel. The pricing was BEYOND reasonable. They don't nickel and dime you like most. Within 15 hrs of giving the quote, Jake came back, installed the brand new, larger circuit breaker panel, and 4.5 hours later he was on his way. I can at least rest easy knowing my mother has a brand new circuit breaker panel installed by an HONEST company, and although I hope I don't have to see an electrician for a while, if I do, I know who I'm calling. Thanks, Garneau!

Trustworthy, Reliable, and Fast Electrician
Derek and Jake were so helpful! Not to mention clean and polite. Before entering our home, they put on shoe protectors to keep our floors clean. I'm so happy to find a trustworthy, reliable, and fast electrician that can help me out around my home. I will be recommending them to all my friends and family.

Stacy Bilodeau
I Highly Recommend Garneau
I highly recommend Garneau! Especially for hard-to-reach places (see photo). From the first call to Garneau the service and follow-through were excellent. Pamela was personable, professional, and always pleasant. She made sure I was kept up to date on everything. Jake and Kyle were great, also friendly and professional. Jake had taken time to scope out the situation before arriving, so he had everything he needed. They got the job done quickly and efficiently and replaced my chirping (for 4 days) smoke detector. Now the chirping is only in my head, but I’m sure it will eventually cease. Thanks to everyone at Garneau.

Todd Spencer
Problem Was Diagnosed and Fixed in a Single Visit
Good experience with Garneau. Scheduling and communications were great with Pam in the office, and Jake, the technician who came out to do the work, was fantastic.
Had a quite convoluted GFCI circuit, modified by the previous homeowner, partially fail, and Jake was able to work through it, including finding a junction box completely hidden in the wall behind a shower.
Problem was diagnosed and fixed in the single visit.
Doug Clougher
Jake and Kyle did an amazing job
Jake and Kyle did an amazing job. The hall light gave them a challenge, but they handled it like a champ. Highly recommend this team.
Kristin Couturier
I Will Never Use Another Electrician
I will never use another electrician for my home! Corey Garneau and his crew are extremely responsive and professional. We had a very complex job (full Enphase 4th gen solar system with 10C batteries), and despite all of this being very new, he installed it perfectly. My town is also particularly picky about inspections, and we were able to pass our wiring inspection on the first try with no issues.
I really appreciated all of the follow-up as well, making sure everything was working and standing by his work. If you need an electrician in this area, look no further!
Ryan Chua
Amazing job diagnosing and fixing
Garneau Electric did an amazing job diagnosing and fixing my electrical issues efficiently. Jake, the technician, provided a few options and was extremely professional.
Rick S

Norman Heinze
Outstanding Work by Jake Williams
Outstanding work by Jake Williams and his partner. They were professional, knowledgeable, and efficient from start to finish. The quality of their work was excellent, and they took the time to explain everything clearly while ensuring the job was done right. I truly appreciate their attention to detail and great attitude. Highly recommend Jake and the Garneau Electric team for any electrical work.
Samuel Tsai
Did an excellent job
Derek and Harry did an excellent job. They were professional, friendly, and courteous. Definitely will be calling again.
Glenn Pierce
Hands down one of the best contractors
Hands down one of the best contractors I have had work on anything related to my house. The generator installation was timed before our first large snowstorm, the owner of the company came out late at night to make sure it was running properly before the storm. That is the kind of customer service you don’t see nowadays.
