Upon inspection of a chimney today I saw something that really made me shake my head. The home was a ranch with a wood/coal furnace in the basement. What I saw in the basement was normal smoke pipe going into a section of class A through a masonary wall. Outside was a vinyl sided sixteen ft. chase with a class A cap on top. After somewhat of a strugle getting on the snow/ice covered roof the cap seemed to be some how connected to the top section of pipe. The top section was very loose so I pulled the cap and top section out of the chase. Little did I know that was the whole chimney. Looking down the chase all I could see was the plywood interior and a piece of class A at the bottom. Needless to say I told the homeowner not to burn , call the guy who built it and I got the heck out of there. I was so baffled that I forgot to even charge him....
