I finally looked up how many house fires start in chimneys each year and the number floored me
Honestly I was just killing time between jobs last week and ended up on the NFPA site reading their chimney and heating fire stats. Turns out around 25,000 chimney fires happen in the US every year, and most of them trace back to creosote buildup that nobody cleaned. I've been sweeping for 6 years and always told customers it matters, but seeing a real number made me realize how many folks are just one cold night away from a bad situation. Ngl it also made me rethink how I explain the creosote stages to people instead of just saying "it's dirty in there." Does anyone here have a go-to way of showing customers how fast that glaze layer builds up?
A guy in Portland had me take a before and after pic of his flue every year, and after three seasons you could literally see the glaze creep up past the smoke chamber. Now I hand new customers a cheap mirror and a flashlight and tell them to check it themselves in January, works better than any speech I've given.
