Common Summer Chimney Issues

After a long winter, many folks look forward to spending the summer enjoying Lake Ontario, Lake Erie, and other outdoor recreation spots in the Greater Buffalo and Rochester area. Although you’re not using the fireplace or heating stove in the summer, your chimney is not out of the woods. Here are five common chimney issues to watch for during the summer:

Chimney Repair Amherst, NYStaining/Efflorescence

When the masonry absorbs moisture, the salt deposits in the clay or shale material in the bricks are drawn to the surface, leaving a white stain when the surface dries. This white staining, known as efflorescence, may only appear on one side of the chimney that is exposed to the most moisture. You may also notice orange stains dripping down the sides of the chimney after it rains due to a rusty chimney cap or chase cover. If not corrected, efflorescence and other chimney stains can lead to masonry damage.

Water Leaks

Water leaks are another common summer chimney issue. Wind, hail, and lightning can damage the masonry, flue liner, chimney cap, and chimney crown that can cause water to leak inside the chimney and fireplace. Heavy rain, hail, and summer heat in the Buffalo-Rochester area can also damage the flashing and rainwater will leak through the gap between the chimney and roof. It can also cause water damage to the attic, roof, ceiling, and walls around the fireplace.

Unpleasant Odors

Our hot and humid summer weather often kickstarts unpleasant chimney and fireplace odors. The oxidization of creosote, soot, debris, and organic matter accumulating in the chimney from the winter releases the odor into the air, which can cause a foul smell throughout your house. Your chimney may need a thorough professional cleaning to get rid of the odor, but it can also be a sign of a leaky chimney.

Animal Entry

It is not uncommon for small birds and wildlife to find their way into your chimney during the summer. They usually gain entry through a broken or missing chimney cap or gaps in the masonry and chimney crown. While inside, they build nests, store food, give birth to their young, and create a mess inside the chimney. They also attract other pests, including roaches, insects, mice, and rats that may make their way into your home through the fireplace.


Humidity and moisture or condensation in the flue are the perfect conditions for mold and mildew to grow inside the chimney. Mold spores multiply rapidly and spread through your ventilation system to other areas of the home, requiring the replacement of portions of your walls, flooring, and ceiling. While not all mold is toxic, it can cause respiratory problems and other health issues.
