A chimney fire can start silently and spread fast, especially in older Franklin homes with wood-burning fireplaces. The 7 warning signs—like thick creosote buildup, a smoky smell indoors, or cracks in the flue—are your early warning system. If you notice any of these in your Brentwood or Thompson’s Station home, call Robert Wilson Chimney LLC for a professional inspection before winter sets in.
What a Franklin chimney inspection actually checks — and why it matters
A chimney inspection is a thorough, methodical walk-through of your chimney system from the firebox to the chimney cap. The Chimney Safety Institute of America recommends three inspection levels depending on use and changes to the system. Level 1 is the standard for most Franklin homes and includes checking the flue interior, chimney structure, and basic safety clearances. We use a high-definition camera to spot hidden cracks, creosote thickness, and blockages that a flashlight simply can’t reveal. In older Franklin neighborhoods like the Historic District or the newer subdivisions off Mack Hatcher, we often find previous repairs that didn’t meet current codes. A proper inspection isn’t just about sweeping—it’s about preventing a chimney fire before it starts. If you haven’t had one in the last 12 months, schedule yours today before your first fall fire.
Thick, tarry creosote layers: The silent Franklin chimney killer
Creosote is the sticky, tar-like byproduct of burning wood. When it builds up to 1/8 inch or more, it becomes a serious fire hazard. In Franklin’s humid climate, creosote can harden into a glaze that traps heat and ignites even at lower temperatures. We’ve seen it in chimneys on the Natchez Trace corridor where homeowners burn green or unseasoned wood. The warning signs are a strong, acrid smell in your living room when the fireplace isn’t in use, or black, shiny streaks on the inside of your glass doors. If you notice either, don’t wait for a cold snap—call us for a creosote removal service before your next burn. A standard Level 1 inspection includes creosote measurement and removal, and costs start at $125 for most Franklin homes.
Cracks in the flue liner: When to worry in your Brentwood or Thompson’s Station home
A cracked flue liner is a direct path for heat to reach combustible wood framing or roof materials. In Brentwood’s older brick homes or Thompson’s Station’s newer builds, we often find hairline cracks that widen over time due to thermal expansion. The warning signs are white, chalky stains on the exterior chimney brick or pieces of flue tile in the firebox. If you see these, stop using your fireplace immediately and schedule a Level 2 inspection, which includes a camera scan of the entire flue. Repairing a cracked liner typically costs between $800 and $2,500 depending on liner type and accessibility. Ignoring it can lead to a chimney fire or carbon monoxide leaking into your home.
Smoke spilling back into your living room: A Franklin fireplace red flag
If smoke rolls into your Franklin living room instead of going up the chimney, your system isn’t drafting properly. Common causes include a blocked flue, a damaged chimney cap, or negative indoor air pressure from exhaust fans. In the fall, we see this often in homes on the Harpeth River where wind patterns shift. The fix might be as simple as a chimney cap installation or a flue cleaning, but it could also signal a cracked flue or improper liner size. Don’t light another fire until a pro diagnoses the issue—smoke spillage can damage walls, ceilings, and your family’s health.
White, chalky stains on the chimney exterior: What the efflorescence means
White, powdery stains on your chimney brick are called efflorescence. They’re a sign of water intrusion, which accelerates mortar deterioration and can freeze and crack tiles in winter. In Franklin’s freeze-thaw climate, this is a common issue for homes built before 2000. The stains often appear after heavy spring rains or when gutters overflow near chimneys on Hillwood Estates or the Berry Farms area. While efflorescence itself isn’t an immediate fire risk, it indicates a leak that can lead to structural damage or a blocked flue. Schedule a waterproofing treatment and inspection before the next storm season using our Franklin-specific checklist.
A roaring sound in the chimney: Is it a chimney fire or just wind?
A loud, roaring sound in your chimney is often the first audible sign of a chimney fire. It’s caused by superheated gases igniting creosote deposits. In Franklin, we’ve responded to calls from homes near the Battle of Franklin Trust sites where homeowners mistook the sound for wind howling through a loose cap. If you hear this, evacuate immediately, call 911, and shut off air supply to the fireplace. Even if the fire seems to stop, the chimney may still be damaged and require a full inspection. The National Fire Protection Association recommends calling a professional even if the fire appears to have self-extinguished.
Damaged or missing chimney cap: The Franklin homeowner’s overlooked risk
A chimney cap is your first line of defense against embers, animals, and rain. In Franklin, missing or damaged caps are common after summer storms, especially in areas like Leiper’s Fork or Arrington where trees overhang rooftops. Signs include birds nesting in the flue, water stains near the chimney crown, or a sudden increase in insects indoors. Installing a new cap costs between $150 and $400 and is one of the most cost-effective ways to prevent chimney fires and water damage. We offer same-day cap installations for Franklin homeowners—just contact us before the next storm.

Frequently Asked Questions
What does thick, shiny creosote in my Brentwood fireplace mean for fire risk?
Thick, shiny creosote is a Stage 3 hazard—it’s highly flammable and can ignite at temperatures as low as 1,000°F. In Brentwood’s older homes, we often find it after burning softwoods like pine. It’s a clear sign you need a professional sweep immediately to prevent a chimney fire.
Why does my Franklin chimney smell like campfire even when I’m not using it?
That smoky smell usually means creosote is off-gassing into your home. In Franklin’s humid climate, it lingers in upholstery and carpets. A Level 1 inspection and sweep will remove the source and often eliminates the odor within hours.
How can I tell if my Thompson’s Station chimney cap is damaged without climbing on the roof?
Look for water stains on the ceiling near the chimney, bird nests in the firebox, or rust on the damper. If you see any of these, your cap may be missing or cracked. We offer free cap inspections—just call us and we’ll check it from the ground.
What’s the first thing I should do if I hear a roaring sound in my Franklin chimney?
Evacuate immediately, call 911, and shut off air supply to the fireplace. Even if the sound stops, the chimney may still be damaged. Do not use the fireplace again until a professional inspects it—this is a true emergency.
