Let's be honest, there are a lot of snow removal companies in the Ottawa area, and I've had a few over the years... one that took all of my money and came twice to clear the snow, one that did an ok job but was rude on the phone, and now I've been with Appleseed (Barrhaven/Westend) for over 3 years - happily : )
I'm not saying the company is perfect, no company is...but they are really good and always trying to improve.
What I like about them is that the owner, Ken, is always communicating with his customers. He sends informative (and often funny) emails to customers with regards to his snow removal PLAN when there is a storm coming. He actually has a plan that he implements so that he can make the best use of his tractors and employees to best serve his customers. And there is a 'tracking system' email you can sign up for so that you know when the tractor is in your area, if for example you need to move your car out of the laneway!
This past weekend was a storm that included snow, freezing rain, rain, and more snow. The driver that looks after my area, Justin, did a fantastic job, so much so that the storm didn't really affect us much. The laneway was cleared wide enough for our 2 cars and he was able to come back to clear once the sidewalk city plows had been by (this most likely due to 'the plan' and the owner's way of tracking the city plows).
I would recommend this company if you are looking for reliable snow removal.
