Appreciation post: the old sweep in Knoxville who showed me why we brush bottom-up on really sooty flues
About 4 years back I was helping out on a job in Knoxville, a 1940s brick chimney that had not been touched in maybe 15 years, and I was going at it top-down like always. An older sweep named Ray stopped me and said "you are just pushing the creosote back onto yourself, son." He had me start at the bottom with a smaller brush first, then work up in stages, and the amount of junk that came loose without packing the flue was night and day. Took us about 40 extra minutes but we pulled out close to two 5 gallon buckets of soot and glaze that would have just sat there otherwise. I still go top-down on light jobs, but on nasty ones I do it his way first. Curious if anyone else was taught bottom-up first, or if that is mostly a regional thing down south?
