My wife and I are in the final stages of our reno in Don Mills. We selected Top Line based largely on the reviews on this site and we weren't disappointed. The company sent the crew to our team at a time and date that worked best with our schedules (and the schedules of the other trades who were finishing up their work). In our case, this meant a Sunday morning time slot.
They showed up on time, they were courteous, and very thorough. I had them clean the air conditioning and furnace after an inspection found them to be very dirty (not surprising considering the reno). Though this was an added cost, I never felt that I was being pressured or 'upsold' for something that I didn't need. They also gave me tips on buying filters for my furnace as the previous owners had not installed them correctly - basic information, but, as a new home owner, I appreciated it.
Having dealt with a number of frustrating experiences with this reno, my dealings with Top Line were a welcome change. Quick, easy, high quality service. Based on our experiences, my parents will be using Top Line for their duct cleaning as well.
