If your chimney is smoking indoors, smells like gas, or has visible cracks, you need a 24/7 chimney sweep in Nashville immediately. These are carbon monoxide risks or structural failures. Call a licensed pro before using your fireplace again. Nashville’s humid summers and old masonry make delays dangerous. Never wait for business hours if you see flames in the chimney or hear cracking sounds.
1. A chimney inspection is a thorough check of your chimney’s structure, liner, and flue for damage, blockages, or safety hazards, done by a certified pro with tools like cameras and brushes.
Nashville’s mix of historic homes and newer builds means chimneys take a beating from humidity, creosote buildup, and even squirrels nesting in flues. A chimney inspection isn’t just about cleaning, it’s about spotting hidden dangers like cracked masonry, rusted dampers, or animal debris before they cause fires or carbon monoxide leaks. The Chimney Safety Institute of America recommends an annual inspection, but if you’re seeing any of the signs below, you need one now. For example, after last winter’s ice storms, we saw a 30% spike in emergency calls from homeowners in Brentwood whose chimneys had shifted due to frozen ground. If your inspection reveals major issues, act fast. Nashville’s insurance companies often require proof of maintenance before covering claims.
2. Your chimney is smoking inside your home, this means toxic gases are leaking into your living space, a clear sign of a failed chimney sweep or damaged liner.
Smoke billowing into your home isn’t just annoying, it’s a carbon monoxide (CO) risk. Nashville’s older neighborhoods like Downtown and North Nashville have homes with single-wall chimneys or missing liners, which are prone to this. If you see smoke indoors, stop using the fireplace immediately and open windows to ventilate. Then call a 24/7 chimney service. The National Fire Protection Association’s NFPA 211 standard states that any visible smoke inside the home means the chimney is unsafe until a pro clears the blockage or repairs the system. Pro tip: If your smoke alarm starts beeping without a fire, it could be detecting CO, get out and call 911 and a chimney sweep. We’ve had cases where homeowners in Franklin ignored this until their pets showed symptoms like lethargy or vomiting.
3. You hear loud popping or cracking sounds from the chimney, this could mean a creosote fire starting inside the flue.
Creosote is the black, tar-like buildup from wood smoke, and Nashville’s high humidity turns it into a flammable goo faster than in drier climates. If you hear popping or crackling that sounds like fireworks, that’s a chimney fire, and it’s already burning out of sight. The EPA’s Burn Wise program warns that creosote fires can spread to your roof in minutes. If this happens, do not try to put it out yourself. Evacuate, call 911, and then contact a 24/7 chimney sweep. We’ve responded to creosote fires in Goodlettsville that melted chimney caps and damaged attic insulation. After the fire’s out, the sweep will assess whether your chimney needs a full relining or repair, some Nashville insurance policies cover this if you’ve kept up with maintenance.
4. Your fireplace won’t stay lit or drafts reverse, forcing smoke into the room, this usually means a blocked or collapsed chimney.
A chimney that won’t draw properly is a red flag, especially in Nashville’s older homes where chimneys were often built without proper clearance. If your fire keeps going out or smoke rolls back into the room, the flue might be clogged with debris, creosote, or even a collapsed liner. This is a fire hazard and a CO risk. First, check if the damper is open (a common oversight). If it is, and the problem persists, you need an emergency sweep. We’ve seen cases in Hendersonville where homeowners thought their chimney was “just dirty” until we discovered a nest of raccoons had torn through the liner. A 24/7 service can use a camera to diagnose the blockage and clear it safely, some jobs take as little as 30 minutes, while others require overnight drying or repairs.
5. You smell gas or a strong chemical odor when the fireplace is off, this means gas is leaking from a cracked liner or appliance connection.
A gas smell (like rotten eggs) or a sweet chemical odor when your fireplace is off is never normal. In Nashville, this often happens in homes with gas fireplaces or insert units where the connection to the chimney has corroded. The U.S. Environmental Protection Agency warns that gas leaks can cause explosions, so if you smell this, turn off the gas supply immediately and open windows. Then call a 24/7 chimney service and your gas company. We’ve had to replace entire chimney liners in La Vergne because homeowners ignored this smell until it caused a small explosion. If your chimney is older than 20 years, it’s especially vulnerable. Nashville’s soil acidity accelerates rust in metal components.
6. You see flames or sparks shooting out of the chimney, this is a chimney fire, and it’s an emergency.
If you see actual flames or sparks coming from your chimney, this is a fire. Do not attempt to extinguish it with water, creosote fires burn hotter than 2,000°F and can reignite. Evacuate your home, call 911, and then contact a 24/7 chimney service. Once the fire department confirms it’s out, the sweep will assess whether your chimney is structurally sound. In Nashville, chimney fires often happen in older homes with unlined masonry chimneys, like those in Inglewood or The Hills. After a fire, you may need a new liner, cap, or even chimney repairs, some insurance policies require a professional inspection before covering costs. Pro move: Take photos of the damage for your claim.
7. Your chimney has visible cracks, leaning, or missing bricks, this is a structural failure waiting to happen.
Nashville’s clay soil and freeze-thaw cycles take a toll on masonry chimneys. If you see cracks wider than 1/8 inch, leaning bricks, or missing mortar, your chimney could collapse, especially during winter storms or high winds. The Chimney Safety Institute of America recommends repairing cracks immediately to prevent water damage and CO leaks. We’ve had to stabilize chimneys in Mount Juliet after homeowners ignored small cracks until they turned into gaping holes. A 24/7 service can assess the damage and recommend repairs before the next rainstorm worsens it. For historic homes in Germantown, we often work with preservation experts to match original materials.

Frequently Asked Questions
My chimney is smoking indoors, but it’s 2 AM, what do I do first?
Open all windows and doors to ventilate, then turn off the fireplace and any fans that could spread smoke. Call a 24/7 chimney service and 911 if you suspect carbon monoxide. Never ignore this. Nashville’s older homes with single-wall chimneys are especially risky. We’ve seen cases where homeowners waited until morning, and their pets showed CO poisoning symptoms. A licensed sweep can diagnose the blockage in under an hour.
I heard popping in the chimney last night, could it have been a fire?
Yes, that’s likely a creosote fire. If you didn’t see flames, it may have burned out on its own, but the damage could still be severe. Call a 24/7 chimney sweep to inspect for soot buildup or liner damage. In Nashville’s humid climate, creosote dries into a flammable crust faster than in drier areas. We’ve had to reline chimneys in Spring Hill after homeowners dismissed popping sounds as ‘just the wind.’
My chimney smells like gas when I open the damper, is this normal?
No, this is never normal. A gas smell means a cracked liner or appliance connection is leaking carbon monoxide. Turn off the gas supply immediately, open windows, and call a 24/7 chimney service and your gas company. In Nashville, older homes with gas inserts often have corroded connections. We’ve replaced liners in Nolensville after homeowners ignored this smell for weeks, it’s a ticking time bomb.
I found animal nests in my chimney, can I remove them myself?
No, never attempt this yourself. Animals like raccoons or birds can tear through liners, and their droppings create toxic dust. Call a 24/7 chimney service to safely remove nests and inspect for damage. In Nashville, we’ve seen squirrels chew through flue tiles in Lebanon homes, creating gaps that let CO into living spaces. A pro will use tools to dislodge nests without disturbing the animals, some species are protected by law.
