Hi all. I'm looking to get my flue cleaned before winter here and I've been searching on google for a chimney sweep. Thing is, most don't have any reviews at all, and the ones that do have two or three tops. I want to get quality work, so are there any questions I should be asking? Certain equipment they should have? Hell, since I just have double walled pipe with two 45 degree bends on a one story, should I just buy the stuff and do it myself?
