Chimney Cap Repair & Replacement


If you are the owner of a chimney that does not have a chimney cap, all we can say is: Get thee to a chimney professional—and fast—or else. By “or else” we mean that your uncapped chimney is putting you at risk of costly home repairs and even a house fire. Fortunately, adding a chimney cap is one of the simplest and least expensive chimney repairs you can make. Usually made of aluminum, galvanized or stainless steel, or copper, a good chimney cap will come with a mesh screening called a spark arrestor that keeps animals out and sparks in on windy days when stray sparks could set fire to nearby trees, leaves and other flammables. The screening built into the cap is designed to create proper drafting while letting wildlife guests know they are not invited in. Stainless steel caps are guaranteed against rust and are usually the most durable caps on the market. However, we are also happy to offer copper chimney caps, which many people love for the patina they develop over time.  You may be wondering …

Why does my chimney need to be capped?

  • To keep out rain, which can be absorbed into bricks and mortar and deteriorate your masonry, compromising your chimney’s structural integrity.
  • To keep animals, birds and insects out—and prevent the odor that accompanies their passing.
  • To keep leaves, sticks and other debris from blocking your flue and starting a fire.
  • To keep sparks from escaping your chimney and catching anything nearby on fire.
  • To eliminate downdrafts.
  • To help keep your masonry and chimney lining in tip-top shape.
  • To ensure that your chimney’s air flow does not get obstructed and prevent toxic gases from properly venting outside of your home.

A Word About Animals Inside Your Chimney


From an animal’s perspective, a chimney is a perfect place to live, as it is nice and tall and secure. But when animals and birds build their nests inside your chimney, they are bringing in materials that are highly flammable. A chimney cap will ensure that your chimney remains free of critters—their skittering and chirping noises, their smells, and their little friends, by which we mean lice, fleas, and maggots. Oftentimes you’ll also find that the baby animals born inside your chimney cannot figure out how to exit your chimney top; this can result in some lingering repulsive odors. But most importantly, these animal nests create a fire hazard and block your chimney so that toxic fumes and smoke can’t escape.
