We are often asked how often to clean my chimney with normal use. We recommend yearly and have a Big Ass Cleaning special for a limited time. More importantly, the yearly inspection determines if future problems are starting to show up.
Our special includes a chimney camera with video capabilities. We run this camera up and down the entire chimney flue and record the results. This shows us any mortar or degrading in the bricks.
The special we are running now includes a full chimney sweep, a camera inspection, a 30 point inspection with a certificate (if you are selling your house soon) and free travel expense within 50 miles of Knoxville, TN. Therefore, it is a sweet deal to jump on our special during this season.
Again, so many customers ask us how often to clean my chimney, we ask how much wood do you burn a year. If you burn a cord (or ric) a year, we recommend yearly inspections and cleaning. 3 cords or more of wood should be inspected twice a year.
