We planned to install a home theatre in our Family room. However, we have our Master bedroom immediately above the family room and found that far too much sound was transmitting through the ceiling/floor - so the kids would have to keep the sound VERY low once my wife and I went to bed.
There seem to be very few companies in the Toronto area that have a clue about soundproofing. Fortunately, we found Canadian Drywall and Acoustics.
Jardel was not only very knowledgeable, but his work ethic was unbelievable, working several very long days, well into the evening hours, in order to get it done. In addition, he also volunteered to do many extras at no cost (ex materials); as he put it: "he's already there". For example, we had a dining room wall that needed a drywall patch due to water damage. Jardel insisted he take care of it. Similarly, he insisted on adding a primer coat when he finished on a Thursday, even though we had painters coming in on the Monday (I hadn't realized Canadian Drywall also does painting). Jardel wanted to keep the dust down for the weekend!
Overall workmanship was excellent. Price was totally fair. Diligence and effort were outstanding. I wouldn't hesitate to use Canadian Drywall again and heartily recommend them to anyone.
