Before Knoxville’s crisp fall air arrives, take these safe DIY steps to prep your chimney for cozy fires. Learn the warning signs that mean stop and call Marshall & Espinoza Chimney Co—your local experts in keeping chimneys safe and efficient.
Clear debris from your Knoxville chimney cap and flue before October’s first fire
Use a sturdy ladder to check your chimney cap and flue for leaves, twigs, or animal nests that Knoxville’s autumn winds can blow in. Wear gloves and eye protection, and gently remove debris with a broom or shop vac—never climb onto the roof yourself. If the cap is damaged or missing, call a pro immediately to prevent water damage or critters from entering. A clear flue means better draft and less smoke in your living room when you light that first fire of the season. Learn more about our full list of services.
Inspect your chimney’s exterior for Knoxville’s seasonal wear and tear
Walk around your home and look up at the chimney from the ground. Check for cracked or missing masonry, leaning bricks, or gaps around flashing—especially after Knoxville’s summer storms. Small cracks can let water seep in, freeze, and expand, damaging your chimney over winter. If you spot damage, don’t seal it with caulk yourself; call a pro to assess whether tuckpointing or a full repair is needed. Learn more about Knoxville chimney cap installation reasons and costs before winter hits.
Test your chimney’s draft with a simple Knoxville homeowner trick
On a breezy Knoxville morning, light a small piece of newspaper and hold it near the open damper. If the smoke rises steadily up the flue, your draft is working. If it puffs back into the room or barely moves, your chimney may be partially blocked or need cleaning. Do not use your fireplace until you resolve this—poor draft can push carbon monoxide into your home. If the test fails, schedule a professional inspection right away.
Never DIY these dangerous chimney tasks in Knoxville—here’s why
Removing creosote buildup, repairing cracked liners, or installing a chimney cap without training risks chimney fires, carbon monoxide leaks, or roof falls. Knoxville’s building codes require licensed sweeps for any work above the roofline. DIY repairs can also void manufacturer warranties on stoves or fireplaces. Leave these jobs to certified pros who carry insurance and know local codes. See our full service list to understand what’s safely DIY versus pro-only.
Warning signs your Knoxville chimney needs a professional now
Stop using your fireplace if you see thick creosote buildup on the damper or flue tiles, smoke backing up into the room, or a strong, acrid odor when the fireplace is cold. Also call a pro if you notice crumbling mortar, white staining (efflorescence), or animals entering through the flue. These signs mean hidden damage or dangerous blockages that DIY tools can’t fix. Knoxville’s damp autumn air worsens existing issues—don’t wait until winter to act.

Frequently Asked Questions
How can I safely check my Knoxville chimney for animal nests before fall?
Use binoculars from the ground to scan the flue and cap for signs of nesting. Never climb onto the roof or insert tools into the flue yourself—animals like squirrels or raccoons can become aggressive if disturbed. If you suspect a blockage, call Marshall & Espinoza Chimney Co in Knoxville to safely remove it and inspect for damage.
What’s the safest way to burn wood in my Knoxville fireplace this fall?
Burn only seasoned hardwood like oak or hickory, and keep fires small and hot to reduce creosote buildup. Never burn treated wood, trash, or wet wood in your Knoxville fireplace—these create thick, flammable residue. Always use a metal screen and keep the damper fully open while burning and until embers cool.
Why does my Knoxville chimney smell like campfire even when it’s not in use?
That smoky odor often comes from creosote deposits or trapped gases in the flue, especially after Knoxville’s humid summers. A professional chimney sweep can remove buildup and install a cap to improve airflow. Don’t mask the smell with air fresheners—it’s a sign your chimney needs maintenance before winter.
