Fireplace systems are surprisingly complex and have a number of different components; unfortunately, this also means that there can be a number of different causes of chimney odors. While a chimney inspection from a certified chimney sweep is often needed to uncover the source of a chimney odor, the following are some of the most common causes of stinky chimneys.
The most common cause of chimney odor is creosote buildup. If your chimney smells like tar or asphalt, it’s probably coming from a buildup of creosote on your chimney walls. According to the Chimney Safety Institute of America, or CSIA, creosote is a natural byproduct of wood-burning.
Downdrafts are another big cause of bad smells creeping into your home. How can you prevent these? We suggest investing in a chimney cap. Some homeowners find themselves with a damaged, poorly installed cap, or lacking one in general. By having a quality chimney cap put in by a team of certified professionals, you can work to eliminate those smelly downdrafts.
Sudden and sharp rotting odors are often cause by the presence of an animal in the chimney. While the body of a deceased animal can create an extremely unpleasant odor, the food, nesting materials, and droppings of live animals can also cause quite a stink.
Water intrusion is a common cause of chimney odors, especially if a musty odor is your problem. Moisture intrusion can damage chimney linings, bricks or mortar. As a remedy, you may simply need a chimney cap or top-mounted damper installed to keep rainwater and moisture out.
A chimney odor is never something to be ignored; instead of trying to mask the smell with air fresheners, call a certified chimney sweep to help uncover the underlying cause. If you are dealing with a stinky chimney give Maine Chimney Sweep a call. 618.235.6364
