Have you been noticing a strange odor coming from your chimney, even when it’s not burning? Fireplace odors can be caused by several different factors, including outdoor moisture and soot buildup. While a chimney cleaning will have it smelling fresh again, learning the source will help you keep it that way in the future. Here are some of the most common causes, and how a chimney cleaning can help.

Here Are Some Reasons Why Your Fireplace Might Smell

1. Water Leaks

Is your chimney sealed around the roof? One of the most common reasons for strange fireplace odors is water that’s dripping into your chimney from rain and snow. This can give chimneys a damp, mildew smell. After having a chimney cleaning done, consider installing a rain cap. This will help guard against excess moisture, as well as the next issue.

2. Trapped Animal

If you notice a foul odor coming from your fireplace, there’s a chance that an animal has gotten stuck in your chimney and died. This can happen with squirrels, raccoons and other animals that are able to scale the roof. A professional will be able to check your chimney to see if this is the case, clear the animal out, and clean the area. Consider installing a rain cap afterward in order to prevent another animal from getting in.

3. Negative Air Pressure 

Negative air pressure causes outside odors to enter the home through the chimney. This is most common during the warmer summer months, but can also be caused by the installation of a new furnace before the onset of winter. Other home improvement projects, such as installing new exhaust fans or roofing, can also cause this negative air pressure issue. 

To combat negative air pressure, consider having a glass fire screen installed. This will prevent warm air from escaping whenever a fire is lit. The homeowner should also keep their fire damper closed whenever the fireplace isn’t in use.
