Keep your Chimney Fresh: 5 Tips to Prevent Unwelcome Smells

Summer’s mild weather is a welcome change from winter’s frigid cool air, but warmer temperatures can bring an unwelcome visitor into your home: chimney odors. The heat and humidity can exacerbate the issue, leading to unpleasant smells permeating throughout your living space. Fortunately, there are effective methods to prevent chimney odors. Here are the top five:


1. Schedule regular cleaning and maintenance.

Odor prevention begins with a well-maintained chimney. Your chimney is less likely to generate odors if it’s been regularly cleaned and inspected by one of our certified chimney professionals. A thorough cleaning will remove any built-up creosote, soot, or debris that contribute to unpleasant smells. Additionally, your inspection will help identify and address any potential issues that may be causing the odor.


2. Properly ventilate your fireplace.

Like other systems in your home, the right ventilation is crucial to prevent odors from accumulating. Make sure your chimney and fireplace have adequate airflow by keeping the damper open when not in use. This helps eliminate any stagnant air or moisture that can lead to odors.


3. Address water intrusion.

Water intrusion is a common cause of chimney odors, and warm weather can exacerbate this problem. Check for signs of water damage, such as discoloration, crumbling masonry, or leaks, and schedule repairs promptly. Ensure that your chimney has a proper chimney crown, a well-fit chimney cap, and intact flashing to prevent water from seeping in. In addition, our CCP-certified chimney profesionals recommend waterproofing the exterior of your chimney to help protect it from moisture damage and subsequent odors.


4. Eliminate nest and debris build-up.

During warmer months, small animals may seek refuge in your chimney. Their nests can cause strong, unpleasant smells as well as potential fire hazards. Likewise, leaves and other debris can enter your chimney, disrupting air flow and contributing to foul odors. Install a chimney cap or spark arrestor to prevent animals and debris from entering the chimney while still allowing smoke to escape. If you suspect an animal has nested in your chimney, contact our professional chimney experts to safely remove the nest and thoroughly clean your chimney.


Pro Tip: Even with proper maintenance, you may still experience residual chimney odors. Place an odor-absorbing material, like activated charcoal or baking soda, near the fireplace or inside the firebox to help absorb unpleasant odors and improve your indoor air quality.


5. Follow best-practice burning techniques.

Finally, avoid burning wet or green wood anytime you use your fireplace, as it can produce excessive smoke and contribute to odor problems. Ensure that the fire is well-established and burning hot to minimize the production of creosote, a major source of chimney odors. Avoid using your fireplace during extremely humid days, as the moisture can intensify odor issues.
