Gavin was super helpful getting my emergency lighting batteries replaced. He was quick and easy to work with. Gigawatts responded to my initial call quickly and understood my tight timeline that I was under. I highly recommend!
We had Gigawatts Electric fix our electrical line to our detached garage and resolve the complex mess of wires on our back patio and front porch. Gavin, Bob, and Mason were a pleasure to work with and I really enjoyed them being here! Very professional and efficient team. They made sure everything was safe and were even able to address some unforeseen issues. We have an older home with very outdated wiring. Everything came out better than I expected. Great company, great people, and I’m glad I was connected to them for my project.
So great working with Gigawatts Electric! Everyone is very professional and easy to work with. They definitely are knowledgeable and can handle basic to complex projects. The owner Mike is great and puts the customer first. Definitely recommend!
Dan and Mason were in our home multiple times for a large reno project in our basement. Their professionalism and expertise was greatly appreciated. Well thought out plan and great execution.Highly recommend both of them!Thank you very much, super pleased with all of the work you completed.
I know these guys since I completed my basement via Meyer Contracting, Gigawatts team did a great and neat job in completing the electrical work hence I called them back to install a 25amps socket for my newly purchased TV stand with fireplace which requires 25amps and not 15amps. First Mike came in, to give me the quote and a week after Noah and Mason came to perform the installation, right from pulling the cables from basement till completion of job, very neat and professional work. Really appreciate them. I have recommended Gigawatts to many of my friends. Once again Kudos team!!
