What’s That Smell Coming from My Chimney?

By | Tagged with: Tags: , , | Comments Off on What’s That Smell Coming from My Chimney?

During the hot and humid months of summer, your home could be invaded by unpleasant odors from the chimney through the fireplace. Even though your fireplace and chimney are probably the last things on your mind in the summer, certain things can be lurking inside the chimney that cause stinky smells. Magic Sweep can help you avoid these situations with a spring chimney sweeping and inspection, and we can also assist you if you do have bad smells coming out of your chimney. We would like to tell you about the most common sources of unpleasant chimney odors to help you determine what that smell could be.

Whats that smell coming from my chimney - Chesapeake VA - Magic Sweep


You have heard that the natural compound of creosote is extremely flammable. The Chimney Safety Institute of America (CSIA) has even called creosote the biggest cause of chimney fires. Not only is creosote a dangerous fire hazard, but it also releases a strong, acrid odor, especially when the weather is hot and humid. If the unpleasant smell coming from your chimney smells like asphalt or bad barbecue, you most likely have a large amount of creosote accumulated on the inside of your chimney. When the CSIA-certified chimney sweeps from Magic Sweep clean your chimney, great care is taken to remove every bit of creosote from your chimney to reduce your risk of a chimney fire and to keep your chimney from releasing unpleasant odors.


If your chimney does not have a chimney cap professionally installed at its top, your chimney will have water and leaves sitting on the smoke shelf. The water not only damages the metal components of your chimney, including the damper and liner, but it also creates a musty odor that can invade your home through the fireplace. When leaves are mixed with water, it causes the leaves to decompose and give off a rotting odor. To prevent this problem, Magic Sweep can install a chimney cap on top of your chimney to keep water and leaves from getting inside.


Another risk you take without a chimney cap is birds, squirrels, raccoons, and other wild animals being able to easily get into your chimney. The droppings of these animals can cause quite a few stinky smells in your home, and, in the worst-case scenario, a bird or animal can become trapped inside the chimney and die. You can imagine the stench created by a dead animal in your chimney. Magic Sweep can keep birds and animals from ever getting into your chimney with a chimney cap that is equipped with mesh metal sides.
