The main purpose of a damper is to seal the fireplace when not in use, making sure the heat stays in your home instead of escaping through your chimney. Having a broken damper or no damper at all is like money out the window. Chimney caps come in all shapes and sizes. More chimney damage occurs from lack of a chimney cap than any other source. A chimney cap not only stops the rain from getting in, but also any birds or other unwanted animals.
Rain can cause premature deterioration of the interior of your chimney. This can allow for eroded flue tiles, loose crumbling mortar (which allows for dangerous cracks and blockages) or at a minimal, a rusted-out damper. Please note that all our stainless steel chimney caps come with a lifetime warranty.
