  • "If you have a need for an electrician and call someone other then Gagnon you are foolish, there is not a better contractor to complete your work. I will use Gagnon for all my electrical needs going forward!"

  • "I had recently moved into a new house that needed a few electrical problems addressed. Bill was great to work with on scheduling time for the appointment. He and his co-worker Shawn arrived promptly at 7:15 am and installed ceiling fan, a difficult bathroom fan and 4 light fixtures with a few hours at a reasonable price. They were great… I would highly recommend Gagnon!"

  • "Great service! Looking on the web, don't call anyone else - they are who you need! Answered my call right away, no machine. On a Saturday, was here w/in 30 minutes and me all fixed up in another 20. Fixed 2 other problems for me while here! Real old-school honest service! "

  • "Called up Bill late in the evening for an issue and he responded right away, which was great. He agreed to come very early in the morning to fix the faulty main circuit breaker. He picked up the parts at like 5 am and came to my house to fix the problem. He was very accommodating. His charges were very very reasonable, even though I did not ask him for the cost of the job upfront. He fixed the problem quickly and professionally. I am so glad I got to know him. Now I have a permanent contact for a master electrician."

    - Hitesh Patel

  • "We had Gagnon's hook up a direct line for our generator for easy access in the event we lost power over the winter. He was there on time, got the job done in less time than he said and did an awesome job at a decent price. I work from home and had only minimal time down without power while they did this install for us. Thanks for hooking us up!"
