Don't just take our word for it – here's what customers in Sarnia say on Google about working with Great Lakes Electric.
I saw Great Lakes number posted, and since no other company replied to my requests for a quote I chose them. Matt was very helpful getting everything organized and gave me a great quote. Dale did an amazing job! He was very organized and worked very quickly! The installation to a new breaker panel went super smooth, the only hold up was on Hydro's end to re-energize the panel. Dale cleaned up and the area is spotless. Overall replacing the fuse panel to a breaker panel only took between 4 and 5 hours. I would definitely recommend having Great Lakes perform any electrical work that you need done!!!
Great Lakes rewired my house and installed a new panel last summer. They were efficient, very quick and punctual. They did a great job. I would highly recommend them.
Prompt, efficient, and great follow-through! Gave detailed quote and showed up on time. Completed work with no problems, then followed up the next day to make sure we knew how everything worked (EV charger installation). Can highly recommend.
They were able to come the same day I called to fix a strange electrical issue in my home. Very happy with the service. I highly recommend this business.
Great Lakes Electric is my go to electrical company in Sarnia. Matt and his team are professional, knowledgeable and efficient.
Replaced my panel, made it very neat and was very polite and fair pricing. Would send my business here again.
Friendly and professional. Job was very well done.
Great service, reasonable price.
Matt was GREAT to talk with, he explained everything in great detail and even mentioned options on doing a future panel upgrade, being cost minded to our over all electric system, since its from the 1970's and not to spend much fixing something, that would be better off to upgrade and wont cost much to repair later on down the road. Very Professional and a GREAT Electrician... You wont be disappointed with his work and attention to details.
I'd recommend Great Lakes Electric for all your big and small jobs! The owner is extremely helpful, answers any questions, easy to deal with and personable. They're very quick to respond and a hard working crew! You should definitely give them a call!
Matt at Great Lakes Electric was great to work with. He was quick, efficient and completed the work safely & without any issues. We really appreciated his expertise and look forward to hiring him again.
