How To Fix Summer Chimney & Fireplace Smells

After using your fireplace all winter, the hot, steamy days of summer can cause your chimney to really stink. Here’s how to stop the stench!

According to’s Jason Raddenbach, consumers’ most common complaint is foul fireplace odors during the summer.

This summer’s humidity is making people’s chimneys and fireplaces smelly. This fragrance is drawn inside the house by the A/C. They clean the chimney, which makes it smell worse,” he explains.

That stinky fireplace:
This is because the chimney has been soaked with creosote (a tar-like byproduct of wood burning) and ash all winter. The humid outside air reacts with the creosote’s acidity. The stink can pervade an entire home.

With an open or poorly sealed chimney (a loose-fitting damper or glass doors), the dryer or bathroom fan creates negative pressure, sucking the odorous air down the chimney and into the living space.
