Found out some wild stats about creosote buildup the other day...
I was reading through an old trade magazine from like 2018 that I found in my uncle's garage. Turns out that a 1/8 inch layer of creosote can actually reduce your chimney's draft by almost 30 percent. I had no idea it was that sensitive to small amounts. I always figured you needed a big chunky buildup before it really messed things up. Made me rethink how often I tell my customers to get inspections even if they think their fireplace is running fine. The article was from the National Chimney Sweep Guild bulletin, pretty dry reading but full of little nuggets like that. Anyone else come across a stat that surprised you about your daily work?
