Before Lexington’s summer heat hits, a quick chimney check can prevent costly damage and keep your home safe. Start with these safe DIY steps and know when to call Swallow Chimney Co for expert help.
Clear the area around your chimney
Trim tree branches hanging within 10 feet of your chimney to reduce fire risk and prevent debris buildup. Remove leaves, pine needles, or bird nests from the roof and gutters near the flue. In Lexington’s humid summers, moisture can accelerate rust on metal parts, so ensure downspouts direct water away from the foundation. If you spot a damaged chimney cap, replace it before critters move in—raccoons and squirrels love unprotected flues.
Inspect the exterior for visible damage
Use binoculars to check the chimney’s masonry for cracks, missing mortar, or leaning sections. Lexington’s clay soil can shift with heavy summer rains, so look for new gaps between bricks or tiles. Pay special attention to the crown—if it’s cracked or eroded, water can seep in and damage the flue liner. Small cracks can wait for a pro, but if you see daylight through the chimney or a section tilting more than an inch, stop and call Swallow Chimney Co immediately.
Test the damper operation
Open and close the damper a few times to ensure it moves freely and seals tightly when closed. A stuck damper wastes cool air in summer and lets heat escape. If it’s hard to move or doesn’t close fully, don’t force it—spray the hinges with silicone lubricant, but if it still resists, a professional can adjust or replace it. A faulty damper can also let rainwater into the flue, leading to rust and mold.
Check for creosote buildup
Creosote is a tar-like residue that builds up inside the flue from wood burning. In Lexington’s humid climate, it can absorb moisture and expand, narrowing the flue or even igniting. Shine a flashlight into the flue from the fireplace or attic—if you see more than 1/8 inch of buildup, it’s time for a professional cleaning. Never scrape or brush the flue yourself; improper tools can damage the liner or send soot into your home.
Warning signs that mean call a professional now
Stop all DIY work if you notice smoke backing up into the room when the fireplace is lit, a strong burning odor even when not in use, or white or rust-colored stains on the chimney’s exterior. These signs often point to a blocked flue, damaged liner, or hidden water damage. Other red flags include crumbling mortar, a chimney that leans, or animals entering/exiting the flue. These issues require licensed expertise—attempting repairs yourself risks injury, voids warranties, and can violate local building codes.

Frequently Asked Questions
My Lexington chimney has white stains on the bricks—what does that mean and should I be worried?
Those white stains are likely efflorescence, a sign of water seeping through the masonry. In Lexington’s humid summers, trapped moisture can weaken bricks and mortar over time. While it’s not an immediate hazard, it indicates your chimney needs waterproofing or repairs. Call Swallow Chimney Co to assess the damage and prevent further deterioration.
Why does my Lexington fireplace smell like campfire even in summer when I haven’t used it?
That smoky odor usually comes from creosote buildup or a damp flue. Lexington’s summer humidity can cause residue to absorb moisture and release odors. A professional cleaning will remove the buildup and eliminate the smell. Ignoring it can lead to more serious issues like mold or a chimney fire.
Can I just cover my Lexington chimney with a tarp to keep it dry this summer?
No—covering your chimney with a tarp traps moisture inside, accelerating rust and mold growth. Instead, ensure your chimney cap is intact and in good condition. If it’s missing or damaged, install a new one before summer storms arrive. A professional can also apply a breathable waterproofing sealant to protect the masonry.
