Covered a fireplace wrong for 5 years until a creosote explosion scared me
I had this one fireplace I swept regular for a home in Portland, always got a ton of creosote buildup but figured that was just typical use. Last spring I finally watched the homeowner light a fire and saw they were covering the top of the insert with a piece of steel after burning, trapping all that moisture and soot. Anyone else had a customer doing something simple that made your job way harder without you noticing till way later?
