Knob And Tube Re-Wiring - Jun 2017

Insurance required that the home be re-wired. Being an older residence located in North Toronto, it was important that the process undertaken did not materially affect the original plaster and mouldings, while also being minimally intrusive to the residents. From quotation through to completion Astron fulfilled its commitments. In just over 1 weeks time, the home was rewired, new circuits, switches and fixtures were added, the main circuit box was updated and on recommendation from Astron, upgraded the electrical services into the property. Ted, Alex and crew are to be commended with their great work, patience and customer care throughout this challenging undertaking.


Great Job! - Jun 2017

Our call for two new electric outlets installed in two bedrooms was answered quickly and an install date was set up for a week later. Alex and Nick showed up, discussed the best option and went straight to work. They exceeded our expectations and went above and beyond to give up what we wanted. Their price was very reasonable. Would definitely use them again and recommend their services. Also, they were careful to clean up and leave the walls in great shape! Job Price


Excellent Service, Professional, Prompt, Knowledgeable, Nice People - Jun 2017

From booking to estimate to job completion, the service was flawless. Ted quoted within 15 minutes. Alex, Dino and Nick showed up on time and completed the job. Job was completed to perfection. All recommendations from the team were bang on. Team was professional, knowledgeable, friendly and cleaned up afterwards. They were a pleasure to do business with from start to finish. We've had many electricians do work in our home but this team is by far, the best. What other electricians couldn't do, Alex, Nick and Dino found a way. HIghly recommend.


Electrical Work and Installation - Jan 02, 2015, Toronto

I'm very happy with the electrical work done by Alex and Simon. They installed a new subpanel, moved 5 circuits from the main panel into the new subpanel, and ran three new circuits (one dryer circuit, and two 15A circuits). The guys were there almost the whole day and the price seemed reasonable for the amount of work needed to be done and the professionalism with which it was carried out. I dealt mostly with Alex and he seems like a straight shooter. Apart from the original quoted work, I asked them to do a few extra things above the original quote and was given a reasonable increase on the spot. I didn't feel any upselling, and just got the sense that they're good guys who do good work. And, they left the place cleaner than they found it

Replaced K&T wiring, added outlets and fixtures - Mar 08, 2013

Astron knows old houses. I interviewed several commercial electrician Toronto -based professionals recommended to me by the Home Service Club, but found that they were all worried about working on my 100-year-old house with its plaster & lath walls, asbestos heat duct wrappings, and knob & tube wiring. It was a relief to me when Astron’s commercial electrician in Toronto told me that they were accustomed to working on the old houses in my neighbourhood. I had Astron replace knob & tube wiring on my ground floor, and add new electrical outlets and lighting fixtures. In all, they installed 16 outlets and 8 electrical fixtures. This work took 3 days. The guys arrived on time and worked hard all day. They were knowledgeable, polite, and cleaned up the work area well. If you are looking for a commercial or residential electrician in Toronto, then Astron Electric is the place to contact. I was impressed that they neatly re-plastered any holes that they had to make in the walls, and removed old wiring that was no longer needed. They told me when there was a problem with an outlet location that I had picked, and we discussed how to rearrange things to work well for me. They told me when an old light fixture was unsafe to reinstall, and they did install a new fixture that I had quickly rushed out to replace it with. I feel that it is important to remain in the house while contractors are working, so that when unexpected issues pop up, they can be discussed and resolved right away. Overall, I was very pleased with their work, and I do plan to hire Astron again next year to replace the knob & tube wiring on the second floor of my house.

Replaced Main Electrical Panel - Feb 13, 2013

I picked this company because they have been in the same location for as long as I have lived here, over 20 years). This company is very professional, and has the capability to send a residential or commercial electrician to Toronto locations. Ted came to see the situation and gave me a fair quote. Alex removed the old panel and did a great job installing the new panel. He was able to use existing wiring and did a very clean job on wiring the panel. He also gave good additional advice, and I would recommend them to replace your main electrical panel.

Interior and Exterior Electrical Work - Sep 18, 2012

At my residence, everything in the kitchen was on the same circuit and needed to be separated. Astron’s electrician installed a new lighting system in the basement using track lights, which look great. They also wired and installed security lights outside our house, which has left us with great peace of mind. The electrician also rewired the bathroom lights because one switch would turn on both the lights and the power plugs. He separated them, and then patched everything back up nicely, so all we have left to do is re-paint once we decide what color we're going to use. You can't even tell there was any work done in the spots where they patched up some holes! They did a wonderful job and we haven't had any issues. Now my entire family calls Astron Electric if they ever require the services of a residential electrician in Toronto. -Marguerite McGuire from Toronto
