I recently had the pleasure of working with James Barrett for some electrical upgrades in my home, and I couldn't be more satisfied with the results. He replaced our outdated electrical panel fuse with a modern circuit breaker, significantly enhancing our home's safety and efficiency. He was prompt and knowledgeable as well. In addition to the panel work, he also handled the wiring for our new doorbell. His attention to detail ensured everything was done correctly, and the final result looks fantastic!

I highly recommend Jim (James Barrett) for any electrical needs. His expertise, reliability, and commitment to quality work truly set him apart. Thank you for a job well done!

Nadia & Anthony C on Barrett Electric Inc.

Jim was outstanding! Communication was great. He answered every question I asked promptly. Arrived on time, price was very reasonable and the work was outstanding. We had a Tesla charger installed and his work is extremely neat and clean. I was very impressed. On the day of ESA inspection the inspector praised me for hiring a professional. That’s how you know Jim is the right guy for all your electrical needs.
There is no question that when I require more electrical work that Jim will be my only call!

I had contact other electricians, but from the moment I had a conversation with Jim, I knew he was the right person for the job!! He completed a thorough inspection and uncovered so many issues that were missed in my previous home inspection. Jim's knowledge, professionalism, and calm demeanour is what I needed and appreciated, during a very overwhelming and stressful situation. I plan to keep him on speed dial, for future work and I very highly recommend Barrett Electrical Inc. Thanks again Jim!!!

Jim was an absolute pleasure to work with. I got in touch with him to discuss adding two new 120v outlets to my garage and wiring up a 240v heater. He got back to me quickly, came out for a quote, and even offered a few of his own suggestions. The installation was efficiently completed in less than a day.

I’ve been raving my family about my experience with Jim and I wouldn’t hesitate to recommend him to anyone looking for a skilled, knowledgeable electrician. Thanks again, Jim!

We just moved into the house and called Jim right away after seeing our old 100A panel. He upgraded it to 200A and I think these photos speak for themselves....can't stress enough how AMAZING his work was. Very attentive to detail. Great price as well. Very very satisfied.
