    My experience from start to finish with Rob and Glenn was a 10/10. It was our pleasure to deal with both Rob and Glenn. They were professional, knowledgeable, polite, took their time to explain and answer all of our questions and had our electricity back up and running to the way it was originally the same day within hours. We will definitely be contacting them for any of our future electrical needs and would recommend this company to anyone as they provided us with an exceptional and quality service.

    After contacting so many others, I finally stumbled upon L&S via a Google search. Immediately, I found that Rob actually understood what I needed to get done. A few texts and pics later, we had a plan. Rob also got an appointment for me the following week. The electrician, Glenn, who came out to do the work was prompt and professional. He called me before he arrived, giving me an ETA, was polite during the whole work time and fixed my issues within 15min. There was a very clear understanding upfront from identifying the problem, coming up with a solution and the price involved. I loved the service and L&S are definitely going to be my first call the next time I need any electrical help! I would recommend Rob and his team without any reservation at all.

    Rob and his team did a great job addressing a recent issue we had. He explained the issue & what needed to be done in a way that was easy to understand and suggested a solution that would save us a bit of money. Great to work with a knowledgeable & honest contractor. Would definitely use them again!

    We used Langstaff & Sloan for extensive knob and tube removal in our new house. Their pricing was good, the crew professional and we were very happy with the work.

    Everything from the receptionist to the electrician was wonderful... extremely professional and pleasant. The electrician was super efficient and everything was completed and checked in record time. I will definitely call them again for any of my electrical work.

    Hands down the best service I have ever received. To start we had an electrician at our door within hours of calling. They thought our issue could be two different things one that would cost thousands of dollars and one that would only cost us the service call + Toronto Hydro coming out. Most business would go right for the wallet but Rob went above and beyond and went the cheaper route first which appears to have solved our problem. That type of integrity and honesty is incredible and for that reason Langstaff & Sloan Inc will be the electricians I use for every job and refer to family and friends! Thank you again for everything Rob!
    Very professional, friendly, and COVID health conscience. Highly recommended. K&S
