Reading an old trade journal from 1978 and the creosote buildup stats shocked me
I was cleaning out my dad's garage and found a stack of 'Sweep's Quarterly' magazines, and one article claimed that in the late 70s, over 40% of the chimneys they inspected in Chicago had over a quarter inch of creosote. I always thought modern heating made that worse, but maybe not. Do you think our methods are actually less effective now, or were they just inspecting worse systems back then?
