I have been using Clean Sweep Chimney & Stove about twenty years. They are nice enough people, and they are very professional. As far as the guy inside the house vacuuming and cleaning up and all - that was all great. They just make it look so easy and quick. They come in, scrape it down, hand you the bill, and then they are gone. They get paid per chimney, and it just seems like they can't wait to get out of there. I haven't used them yet this year, but they are good people. I know they are trying. I will probably still use them because they do a good job. I just wish they would be a little more personable.
