Hot air from your furnace or cold air from your chimney may be flowing right out of your chimney. A damper in your chimney is exposed to extreme heat and temperature changes, and that can cause it to warp. You can keep that air in your home with a tight sealing damper cap.
With no cap leaves, raccoons, squirrels and birds can easily get into your chimney and damage it. Or, they can fall inside your chimney and die, causing an unpleasant odor in your home. A damper caps helps keep unwanted pests out of your chimney.
