Chimney Odor

Though fireplaces and chimneys make your home more cosy and comfortable, they require maintenance to ensure they work well. In certain situations, chimneys tend to develop a strong odor that’s unpleasant for inhabitants.

Chimney odours are most likely to occur during the rainy season or summertime when the moisture heats up due to the humidity. Odours coming from the chimney are frustrating as they make the home quite unpleasant to live in.

Diagnosing the cause of the odor is a step in the right direction. Here are some possible reasons for chimney odors:


When the fire burns in the fireplace, the smoke that enters the chimney leaves behind a substance known as creosote. Creosote is a sticky black substance that’s flammable and must be removed from the chimney on a regular basis. This substance is tricky to remove and if the job isn’t done correctly, this can come back to haunt you in the summer.

This substance has a strong odour that’s difficult to miss. Its odor can be described as hot asphalt.



Just like the gutter of your home, the chimney also collects debris from the trees nearby and anything that blows across the rooftop. This problem is amplified if you don’t have a chimney cap. This debris eventually forms a clog in the chimney when ignored for a considerable period. The debris begins to decompose, leading to a strong odour. If you begin smelling rotten leaves, call up a professional to clear the chimney out.

Chimney leaks

Chimney leaks can occur due to a number of reasons and they can cause significant damage as well like the growth of mold and mildew which has considerable health implications. Moisture gets into the chimney and during summers the odour begins to build up. Since there are many reasons that can cause a chimney leak, a close inspection by a professional is needed to determine the cause and deal with the situation.

Animal invasion

Birds and small animals tend to get stuck in the chimney, causing a foul odour. The odours caused by animal intrusion can vary. An overpowering decaying smell around the house is an indicator that an animal has got through the system. Animal droppings can also cause a distinct odour in your home. To prevent such issues from happening in future, make sure all parts of the chimney is installed correctly and is in good shape.
