Keeping Animals Out of Your Chimney


If your chimney isn’t protected, you could find it playing home to an animal. Whether they enter the chimney by accident or are tempted into building a nest by the warmth and shelter of the chimney, birds, bats, raccoons, and squirrels are common intruders in chimneys. Those intruders can cause some serious problems, which is why you should take measures to prevent animals in your chimney.

Keeping Animals Out is Important

Once inside your chimneys, animals can bring a host of problems. At the very least, you can’t use your fireplace if the chimney is blocked by a trapped animal or an animal nest. And having animals removed from your chimney by a professional can be expensive. Some of the other problems animals in chimneys can cause include:

  • Chimney damage. A trapped, frantic animal can damage your chimney with clawing and scratching. A nesting animal can damage the chimney as it enters and exits, and as it builds the nest.
  • Fire hazard. Animal nests are usually constructed of flammable materials. If you have a nest in your chimney that you’re not aware of and you light a fire, the nest could ignite and start a chimney fire.
  • Carbon monoxide hazard. If your chimney is blocked by an animal or an animal nest, gases generated by your fireplace, including carbon monoxide, can’t exit the chimney. That can cause the gases to build up to dangerous levels within your home.
  • Foul odors. If a trapped animal can’t escape the chimney, it can die and decay, filling your house with a horrible smell. Nesting animals can leave behind smells from droppings, rotting food or rotting nesting materials.
  • Diseases. Animals carry diseases. When they enter your chimney, they carry a risk of spreading those diseases to your family or your pets.

Prevent Animals From Entering Your Chimney

There are three primary ways to protect your chimney from animal intrusions:

  • Chimney caps. Chimney caps are perhaps the most common method for keeping animals out of your chimney. Chimney caps cover the chimney opening, and a proper chimney cap is surrounded by a metal cage to keep out animals and debris.
  • Top-sealing dampers. Top-sealing dampers close off your chimney entirely when the chimney isn’t in use, keeping out water, animals, and debris. When the chimney is in use and the damper is open, the damper opening should be enclosed with a wire cage to keep animals out.
  • Chimney sweepings and inspections. A chimney sweeping and inspection won’t keep animals out of your chimney, but a chimney sweep can spot a trapped animal or signs of an animal nest. A chimney sweep can clear away any signs of an animal nest or animal droppings, and he can help with any repairs needed due to damage caused by animals.
