Raccoon family moved in and taught me about drafty flues
I got a call from a lady in Boise who said her fireplace was making scratching noises. Thought it was a stuck damper, but when I opened the cleanout I found a mama raccoon and 3 babies chilling on the smoke shelf. Turns out they tore through a cracked crown and were basically living in the flue, which explained why her living room always smelled like a wet dog. I fixed the crown, installed a proper cap, and now I check every chimney for animal signs before I do a sweep. Has anyone else had critters mess with their draft or cause weird airflow?
