custom chimney cap sizes Available

Chimney caps come in a variety of shapes, sizes and materials. They are typically made of galvanized metal or stainless steel. Our stainless steel chimney caps provide a lifetime warranty. We carry sizes to fit single or multi flues. We also provide custom chimney cap sizes for challenging installations.


Although it may seem like a decorative topper to your chimney, the chimney cap is actually one of the most important parts of your entire chimney system. It is the primary piece (other than the crown) that protects your flue from moisture, debris and animal entry.


The chimney cap sits on top of the chimney flue and protects the entrance of the flue against any damaging forces. Without a chimney cap – or if the existing chimney cap is damaged – the flue is vulnerable to damage and deterioration.


dangers of having an uncapped chimney

Animals such as birds, raccoons and roof rats are notorious for attempting to find their way into chimneys. An uncapped chimney is an invitation for animals to use your flue as a nesting ground or hiding place, potentially blocking the flue and exposing your family to bacteria, disease and fire hazards.


Without a chimney cap, falling leaves, twigs, trash or even stray balls can fall into the flue. This debris can create a blockage, encourage mold growth and even ignite when the fireplace is used.


Water can be incredibly damaging to a chimney. Without a chimney cap, water from rain, snow or ice can easily damage the flue and surrounding building materials. Likewise, water can cause the metal damper to rust or the bricks and mortar in the firebox to crack and crumble.
