TIL my old way of checking for blockages was missing a lot
I was sweeping a big old farmhouse chimney in Burlington last week and the owner mentioned a faint smoke smell even after my clean. I finally borrowed a neighbor's inspection camera and saw a huge bird nest about 15 feet down a side flue I never even checked. I've been just using a mirror and flashlight for years. Has anyone else found a better tool for spotting those hidden side pockets?
