I have been doing renos in my home for 2 years and after completing my livingroom and diningroom it's time to take a break. I have heard from others that duct cleaning is a scam well Top Line proved that wrong. I called them asking if they could come the next day and they fit me in at 8pm, which was great as I had already missed enough time away from work dealing with other contractors. The job turned out to be a big job as my ducts were very bad, think it had something to do with me ripping all the plaster walls down and not covering the vents. They charged me a little more than quoted but I was fine with that. It took 3 of them about and hour to do the job and they showed me what was coming out of my vents, all I can say is that it was incredible, wood, plaster, rocks, and dust that was so big it looked like insulation. I was very happy with the job and the crew that did my job.
