Bloomington summers bring heat and storms—your chimney needs seasonal prep to stay safe and efficient. Start with these safe DIY steps, then know when to call a pro before fall’s peak season rush.
Clear debris and inspect the crown from the ground
Stand back and use binoculars to check your chimney crown for cracks or missing mortar—common in Bloomington’s freeze-thaw cycles. Remove any twigs, leaves, or bird nests blocking the flue cap with a broom or hose (never climb onto the roof). If the crown looks damaged, call us before summer storms arrive. A cracked crown can let water seep in, leading to costly repairs later.
Check the flue liner and damper for summer airflow
Turn off your HVAC and open the damper fully. Shine a flashlight up the flue to spot obstructions or a damaged liner—especially important in older Bloomington homes. If the liner is cracked or the damper won’t open/close smoothly, it’s time for a pro. A blocked flue can trap heat and create dangerous backdrafts. Learn more about liner safety.
Test your chimney’s draft with a simple tissue test
Light a small piece of newspaper, hold it near the open damper, and watch the smoke. If it blows back into the room, your chimney isn’t drafting properly—often due to debris, a cold flue, or a cracked flue liner. In Bloomington, summer humidity can worsen draft issues. If the smoke doesn’t rise steadily, schedule an inspection before using your fireplace this fall.
Clean the firebox and ash removal (safely)
Remove old ash with a metal shovel and bucket—never vacuum (ash can contain live embers). Scrub the firebox with a stiff brush and mild detergent, then rinse and dry. Avoid harsh chemicals; Bloomington’s humidity can cause residue buildup. If you notice thick creosote buildup (black, tar-like layers), stop and call a pro—it’s a fire hazard. See our safe cleaning guide.
Warning signs: Stop DIY and call a pro immediately
If you spot white efflorescence (salt stains), spalling bricks, or a leaning chimney, these are signs of water damage—common in Bloomington’s humid summers. Other red flags: a strong campfire odor, smoke backing into the room when the damper is open, or visible cracks in the masonry. These issues require professional repair to prevent structural failure or carbon monoxide leaks. Learn the risks.

Frequently Asked Questions
How can I tell if my Bloomington chimney crown needs repair before summer storms hit?
Look for visible cracks, missing mortar, or uneven surfaces on the crown from the ground. If you see gaps larger than a dime or pieces missing, water can seep in and cause freeze-thaw damage—common in Bloomington’s variable summer weather. Call us for a professional assessment before the next rainstorm.
Is it safe to use my Bloomington fireplace in summer if I’ve never had it inspected?
No. Summer humidity and pollen can clog flues, and undetected cracks may worsen. Even if you don’t use the fireplace, a professional inspection ensures no hidden damage exists. Schedule one now to avoid costly repairs later. Bloomington’s weather can accelerate wear year-round.
What’s the easiest way to check my chimney’s draft in Bloomington’s summer heat?
Turn off your AC, open the damper fully, and hold a lit incense stick near the flue opening. If the smoke drifts into the room or doesn’t rise steadily, your chimney isn’t drafting properly. This is often due to debris or a cold flue—common in older Bloomington homes. We can diagnose the issue.
