BRUSHES: The largest selection in stock! This is just a small sample of chimney brushes that we carry....... Every chimney needs to be cleaned periodically. The build up creosote causes chimney fires--wood is the worst culpret. Measure flue size and height of chimney... you'll need a brush either the same size or slightly smaller than your flue. You can attach rods to the brush or use rope to drag. We carry various sized brushes and special brushes for pellet stoves!
