A professional chimney sweep in Murfreesboro or Gallatin isn’t just about cleaning, it’s about catching early warning signs like excessive smoke, strange odors, or soot stains before they turn into chimney fires or costly repairs. Nashville’s high humidity and older brick homes make routine maintenance non-negotiable. If you notice any of these 7 signs, schedule a sweep before winter’s first fire.
1. A chimney inspection is a visual and diagnostic check of your flue, liner, and structural integrity, unlike a sweep, which removes creosote and debris. In Murfreesboro and Gallatin, where older homes with brick chimneys dominate, inspections should happen annually, especially before fire season.
Checking your chimney’s condition and cleaning it out are not the same task. One looks for hidden problems while the other removes built-up soot and debris. While a sweep clears out creosote and soot, an inspection looks for cracks, rust, or deterioration in your flue lining, crown, or masonry. In Murfreesboro and Gallatin, where many homes have brick chimneys built decades ago, these inspections are critical. The Chimney Safety Institute of America (CSIA) recommends a Level 2 inspection, where the technician looks inside the flue, at least once a year for homes using their fireplaces regularly. If you’ve noticed drafts or smoke spilling into your home, that’s a red flag. The inspection will tell you if your chimney is structurally sound or if it’s time for repairs before the next cold snap.

2. Excessive creosote buildup looks like black, tarry deposits on the flue walls. In Nashville’s humid climate, creosote dries harder and faster, turning into a flammable glaze that’s a leading cause of chimney fires in Murfreesboro and Gallatin.
Creosote isn’t just a nuisance, it’s a fire hazard. When wood burns, it releases condensable gases that stick to cool flue walls and harden into creosote. In Nashville’s high-humidity summers, creosote dries into a glass-like coating that’s highly combustible. If you see thick, glossy black deposits during a sweep or notice soot stains on your fireplace mantel after burning, your chimney is at risk. The National Fire Protection Association (NFPA) reports that creosote is involved in 25% of all chimney fires, and many of those start in homes that haven’t been swept in over a year. In Murfreesboro and Gallatin, where older homes with unlined flues are common, this risk is even higher. See how often you should sweep based on your wood type.
3. Smoke backdrafting into your home means your chimney isn’t drawing properly. This often happens in Gallatin’s newer subdivisions with tall, modern homes where wind patterns disrupt drafts, or in Murfreesboro’s older homes with deteriorated flues.
If smoke fills your living room instead of rising up the chimney, your flue isn’t venting correctly. This can happen for a few reasons: a blocked chimney (from debris or animal nests), a cracked liner, or poor draft due to wind direction, common in Gallatin’s hilly terrain. In Murfreesboro, older homes with single-wall masonry chimneys are especially prone to draft issues as the flue narrows over time. The EPA’s Burn Wise program advises that a proper draft is essential for safe, efficient burning, and backdrafting can push carbon monoxide into your home. If you’re lighting fires and getting smoke in the room, don’t ignore it. A professional sweep can check for blockages, while an inspection will reveal if your flue needs relining or repair. Learn how to test your chimney’s draft safely.
4. Rust stains on your chimney cap or crown signal moisture damage. Nashville’s frequent rain and humidity accelerate rust in metal caps, especially on older homes in Murfreesboro’s downtown historic district.
A rusted chimney cap isn’t just unsightly, it’s a sign your chimney is letting in water. In Nashville, where summer humidity lingers and sudden rainstorms are common, moisture seeps into small cracks in your crown (the top of your chimney) or rusts out metal caps over time. If you notice orange-brown streaks running down your brick or rust flakes near the cap, water is getting in. This can lead to masonry erosion, rusted flue liners, and even structural weakness. In Murfreesboro’s older homes, where many chimneys lack proper waterproofing, this is a frequent issue. A professional sweep can assess the damage during your appointment, and we often recommend sealing or replacing caps to prevent further deterioration. See how to waterproof your chimney before winter.
5. Animal nests or debris in your chimney create blockages that restrict airflow. In Gallatin’s wooded areas, birds and squirrels are drawn to chimneys, while Murfreesboro’s urban sprawl means leaves and twigs often clog flues after storms.
Animals don’t just make a mess, they create fire hazards. Birds, squirrels, and even raccoons will nest in chimneys, especially in Gallatin’s wooded outskirts where trees provide easy access. Even debris like leaves or pine needles can build up after Nashville’s summer storms, restricting airflow and increasing creosote buildup. If you hear scratching or see feathers, fur, or twigs around your chimney, there’s likely a blockage. The NFPA warns that blocked chimneys are a leading cause of chimney fires, as restricted airflow causes incomplete combustion and excess soot. A professional sweep will remove the debris and check for damage from nests or roots. Learn how to animal-proof your chimney.
6. A strong, unpleasant odor when lighting your fireplace means unburned fuel or creosote is off-gassing. In Nashville’s older homes, this often signals poor combustion or a dirty flue.
That acrid, chemical smell when you light your fire isn’t normal. It usually means unburned fuel or creosote is breaking down and releasing gases into your home. In Nashville’s older homes, especially those in Murfreesboro’s historic neighborhoods, poorly maintained chimneys or inefficient fireplaces can cause incomplete combustion. If you smell something sharp or tar-like, your chimney might be too dirty or your fireplace isn’t getting enough oxygen. The U.S. Environmental Protection Agency notes that improper burning can release harmful pollutants, including carbon monoxide. A professional sweep will clean out the flue, and we can also assess whether your fireplace needs adjustments or a new damper for better airflow. See how to burn wood safely in Nashville’s climate.
7. Cracks in your chimney’s masonry or flue liner reduce structural integrity. In Murfreesboro’s older homes, settling or freeze-thaw cycles can cause hairline cracks, while Gallatin’s newer builds may have improperly installed liners.
Cracks in your chimney aren’t just cosmetic, they’re a safety hazard. In Murfreesboro, where many homes date back to the early 1900s, settling and age-related wear can cause small cracks in the masonry. In Gallatin, newer homes might have cracks due to improper flashing or liner installation. Even tiny cracks let in moisture, which accelerates rust and masonry deterioration. The CSIA recommends sealing cracks with a high-quality chimney sealant, but larger cracks may require repointing or even partial chimney reconstruction. During a sweep, our technicians will inspect for cracks and recommend repairs before they lead to water damage or structural failure. Learn how to spot hidden chimney damage.

Frequently Asked Questions
It’s been a year since my last sweep, can I still book one before the cooler months?
No, it’s never too late. Nashville’s humidity means creosote builds up faster than in drier climates, and unswept chimneys are at higher risk for fires once you start burning again. Schedule a sweep now to clear last winter’s buildup and prevent a dangerous buildup during fall use. See our fall chimney prep tips.
I noticed soot stains on my fireplace mantel after burning a single log. Does this mean my chimney needs a sweep?
Yes, soot stains after just one burn indicate poor combustion or a dirty flue. In Murfreesboro and Gallatin, where older homes often have unlined chimneys, this is a common sign of creosote buildup. A sweep will remove existing deposits and improve airflow for cleaner burns. Learn how wood type affects soot.
My chimney cap is rusted, but the rest of the chimney looks fine. Should I replace it now or wait?
Replace it now. A rusted cap won’t protect your chimney from water intrusion, and Nashville’s rain and humidity will accelerate damage to your flue and masonry. A new stainless steel cap costs between $150 and $300 and can prevent costly repairs down the road. See our chimney cap recommendations.
I live in a newer home in Gallatin with a stainless steel liner. Do I still need annual sweeps?
Absolutely. Even stainless steel liners collect creosote, and newer homes with tight drafts can still suffer from poor combustion. The NFPA recommends sweeping at least once a year for all chimneys, regardless of material. Learn how often to sweep based on your setup.
