John Stewart Richards
Alex was a great help. They sorted out electrical on my Kitchen reno. Great to see pros at work. Also found me a rare missing circuit breaker panel screw!!
Eli Kim-Swallow
We recently had Astron replace all of the knob and tube in our old home and they were amazing. Alex, Dino, and Phil were great and the team worked quickly and efficiently navigating the entire project. If you have an older home and need your knob and tube fully replaced and electric updated - these are your guys!

Astron recently replaced all the old knob and tube wiring in my century home, and I couldn’t be more impressed. From start to finish, their professionalism stood out; they were punctual, respectful of the space, and communicated clearly throughout. The quality of their work is outstanding. They approached everything with care and attention to detail, and their work ethic was next-level. It’s rare to find a crew that takes so much pride in what they do. Highly recommend Astron to anyone looking for top-tier electrical work.
Jonathan Philp
Excellent service by Alex and Dino at Astron Electric. Alex was fast to respond and quote a job in my kitchen, and was able to get a team over to my house very quickly. Dino and his crew were awesome and finished the project quickly and professionally. I am very happy with the end result, and will not hesitate to recommend their services to family, friends, and clients!
Duncan Palmer
Alex and his team were fantastic. They upgraded our panel and service. Walked us through the process with hydro. It was smooth as silk. But they really shined with the install of our sauna heater and light. It was an outside job (-4c) and they worked non-stop to get it done. Not only was the work technically good but the care they took to make it look good was next level. Thanks Astron.
