As a Knoxville homeowner, you can handle simple chimney maintenance like visual checks and cap cleaning—but never DIY inspections or repairs. Learn the safe steps, warning signs, and when to call a licensed pro like Murphy & Guerrero to keep your chimney safe and efficient.
Start with a quick visual check: what Knoxville homeowners can see safely
Every few months, grab binoculars and inspect your chimney from the ground. Look for missing or damaged bricks, cracked mortar, or leaning sections—especially after Knoxville’s spring storms. Check the chimney cap for rust or debris blocking airflow. If you spot gaps wider than a credit card, call a pro. For a closer look, use a flashlight inside your firebox to check for excessive soot buildup or signs of water stains on the damper. Keep an eye on your flue liner too; if it’s cracked or missing chunks, that’s a job for Murphy & Guerrero Chimney Co. Never climb onto your roof yourself—Knoxville’s unpredictable weather and steep pitches make it risky.
Keep critters out: clean and inspect your chimney cap in Farragut or Oak Ridge
Your chimney cap is the first line of defense against Knoxville’s squirrels, raccoons, and birds. Once a year, remove leaves and nests from the cap and screen using a sturdy brush or shop vac. If the cap is bent or missing, replace it immediately—unprotected flues invite pests and rain damage. In Farragut or Oak Ridge, where humidity is high, rusted caps corrode faster. Check the screen for holes; even a small tear lets debris and animals in. If you’re unsure about installation, Murphy & Guerrero Chimney Co offers cap repairs and replacements with local warranties.
Soot and ash: how to safely clear your firebox after a Knoxville winter
After your last fire of the season, let the ashes cool for 24 hours. Wear gloves and a dust mask, then scoop ash into a metal container with a tight lid—never use plastic or paper. Leave a thin layer (about an inch) to insulate coals for next season. For stubborn soot on the firebox walls, use a stiff brush and a shop vac with a HEPA filter. Avoid harsh chemicals; they can damage masonry. If you notice thick, tarry buildup or a strong chemical odor, that’s creosote—call a pro immediately. Knoxville’s damp springs can worsen creosote problems, so don’t wait. Explore our full list of services.
Warning signs your Knoxville chimney needs a pro—don’t ignore these
Stop DIY work and call a licensed sweep if you see smoke backing up into your living room, a strong campfire smell lingering after fires, or white, chalky stains on your chimney’s exterior (efflorescence). Cracked or crumbling bricks, a rusted damper, or soot falling into your firebox are red flags. In Knoxville, where sudden temperature swings can stress masonry, listen for unusual noises like popping or rumbling—it could signal a liner failure. If your chimney leans or has shifted, that’s structural and dangerous. These issues won’t fix themselves and DIY repairs can void warranties or worsen damage.
What you should NEVER DIY in your Knoxville chimney—and why
Never attempt a chimney inspection yourself—even with a camera. Knoxville’s tight flues and hidden cracks require professional tools and training. Avoid power-washing your chimney; high pressure can dislodge bricks and damage mortar. Don’t seal cracks with caulk or paint; proper repairs need heat-resistant materials like refractory cement. Skip DIY chimney sweeping with shop vacs or leaf blowers—they can’t remove dangerous creosote buildup. Lastly, never install a new liner or cap without checking local codes. Knoxville’s building department enforces strict standards, and improper work can lead to fines or dangerous gas leaks.

Frequently Asked Questions
My Knoxville chimney smells like a campfire even when I haven’t used it in weeks—what’s causing this and what should I do?
That smell is likely creosote buildup or trapped moisture reacting with soot. Knoxville’s humid springs make this worse. First, check for water stains or white mineral deposits on the chimney’s exterior. If you see either, call a pro immediately—DIY fixes can trap moisture and worsen the problem. Murphy & Guerrero Chimney Co can perform a Level 1 inspection to diagnose the issue and recommend safe, effective solutions.
Why does my chimney in Farragut have white stains on the bricks, and is this just cosmetic or something to worry about?
Those white stains are efflorescence, caused by water evaporating and leaving mineral deposits behind. In Farragut’s damp climate, this signals water intrusion—even if you don’t see leaks. While it may look cosmetic, it weakens mortar over time and can lead to bigger cracks. Don’t ignore it; call a pro to assess waterproofing needs. Murphy & Guerrero Chimney Co can apply breathable sealants to protect your chimney without trapping moisture inside.
I’m buying an older home in Knoxville with a brick chimney that hasn’t been used in 10 years—should I get it inspected before my first fire this winter?
Absolutely. A decade of disuse means potential blockages, critter nests, or hidden cracks—especially in Knoxville’s freeze-thaw climate. Even if the chimney looks fine from the ground, a Level 1 inspection by Murphy & Guerrero Chimney Co will check the flue, liner, and masonry for safety. Skipping this step risks carbon monoxide leaks or chimney fires. Schedule your inspection now at contact us to avoid last-minute surprises before winter.
