Why your fireplace smells in summer

Humidity and Moisture

Humidity is a common cause of fireplace odors in summer. Moisture in the air can mix with soot and ash left inside the chimney, creating an unpleasant smell that infiltrates your home.

To reduce moisture-related odors, ensure the damper is closed when the fireplace is not in use and consider installing a chimney cap to keep out rainwater. Regular cleaning can also help reduce buildup that leads to odors.

Animal Intrusions

Animals such as birds, squirrels, or raccoons may find chimneys an attractive place to build nests during warmer months. Their presence can lead to foul smells if they leave droppings or debris, or worse, become trapped.

To prevent animals from entering your chimney, consider installing a sturdy chimney cap with a mesh screen, and make sure to schedule routine inspections to check for and remove any unwanted animal guests.

Creosote Buildup

Creosote is a byproduct of burning wood that can accumulate in the chimney lining. During the humid summer months, creosote can emit strong, smoky odors that waft into your living spaces.

To mitigate the smell of creosote, have your chimney professionally cleaned. Regular sweeping removes creosote deposits, improving air quality in your home and reducing the risk of chimney fires when you start using the fireplace again in cooler months.
