Common Fireplace Problems That Start in Summer

Except for possibly decorating the mantel for the season, most homeowners don’t touch their fireplace or woodstove once the heating season ends. And why would they? There’s little need for their warmth and much more desire to enjoy the fresh air outdoors. However, summer can be surprisingly hard on chimneys, fireplaces, and wood-burning appliances. When they sit unused, humidity, summer storms, and wildlife can all contribute to problems that may not be noticeable until the first cool day of fall.

By understanding the issues that commonly develop during the summer months, you can address small concerns before they become expensive repairs or safety hazards.

Water Damage: Summer’s Biggest Threat to Your Fireplace

Moisture can find its way into your fireplace and chimney in several ways during the summer months. High humidity can leave dampness trapped inside the system, while summer storms may introduce water through a missing or damaged chimney cap, deteriorating flashing, or cracks in the masonry. Once moisture gets inside, it can create a variety of problems throughout the system.

Moisture can cause rust on metal components such as dampers, chimney caps, stove pipes, fireplace doors, and wood stove parts. It can also contribute to masonry deterioration as water works its way into small cracks and mortar joints. In some cases, trapped moisture can even create unpleasant odors inside your home.

Signs of water intrusion may include:

• • Water stains on walls or ceilings near your fireplace
• • Damp or musty odors
• • Visible cracks or deterioration in masonry
• • Rust on metal components

If you notice any of these warning signs, don’t wait. Addressing your water issues during the summer can help prevent more extensive repairs later. It's also often easier to schedule inspections and repairs before the busy fall season begins.

Birds, Squirrels & Other Unwanted Guests

Summer is the prime nesting season for many animals—birds, squirrels, raccoons, and insects may seek shelter inside your chimney. But making their home in your chimney brings risk to your home. Nests can block your flue, creatures can damage chimney components and create unpleasant smells. Worst of all, they can create a fire hazard. Their nests are highly flammable. But if you’re not paying attention, you may never know they’re even there until you light a fire in the fall. A properly fitted chimney cap can help keep animals out while still allowing your chimney to vent properly.

Small Issues Become Big Problems

One of the biggest challenges with fireplace and chimney issues is that they often develop slowly. Because most homeowners aren't using their fireplace or wood stove during the summer, problems can go unnoticed for weeks or even months.

A small leak may not seem significant at first, but continued moisture exposure can lead to more extensive damage. A minor masonry crack can allow water to enter and worsen over time. An animal nest can remain hidden until the first fire of the season. Even a rusted or stuck damper may not be discovered until you try to use your fireplace on the first chilly evening of the season.

The longer these problems go unaddressed, the more expensive and inconvenient they can become. Identifying and correcting issues during the summer helps ensure your fireplace or wood stove is ready when you need it most.

Get Ahead of Fireplace Problems This Summer

While fireplaces and wood stoves may be out of sight during the summer months, they shouldn't be completely out of mind. Water intrusion, animal activity, and other issues can develop while your system sits unused, creating problems that may not become apparent until cooler weather arrives.

A quick inspection during the off-season can help identify potential concerns before they become costly repairs. Taking care of small issues now can help ensure your fireplace or wood stove is ready to provide safe, reliable warmth when fall returns.
