Carbon monoxide leaks from chimneys in Murfreesboro are most common in older brick homes with cracked liners, blocked flues, or improperly sealed masonry. If you smell gas, feel dizzy near the fireplace, or see soot outside the chimney cap, evacuate immediately and call 911. A professional chimney sweep can inspect for leaks and blockages before winter makes them deadly. Never ignore these signs, carbon monoxide kills silently, and Murfreesboro’s humid summers worsen masonry deterioration faster than most homeowners realize.
When does a chimney issue in your Murfreesboro brick home cross from ‘annoying’ to ‘emergency’? (Hint: It’s not just creosote buildup.)
A chimney emergency in Murfreesboro isn’t just smoke or soot, it’s when your fireplace or stove starts leaking carbon monoxide (CO) into your home. This happens when combustion gases can’t escape through the flue due to blockages, cracks in the liner, or damaged masonry. Older homes built before the 1980s, especially those with brick chimneys and no stainless-steel liners, are at higher risk. The problem worsens in Murfreesboro’s humid climate, where moisture seeps into mortar joints and accelerates deterioration. If your chimney isn’t properly maintained, a single cold snap can turn a minor issue into a life-threatening leak. The Chimney Safety Institute of America (CSIA) warns that most CO-related chimney failures start with undetected cracks in the liner or a collapsed crown, both common in Murfreesboro’s older brick homes after years of freeze-thaw cycles.
How to tell if your Murfreesboro chimney is leaking carbon monoxide
Carbon monoxide doesn’t have a smell or color, but these signs mean your chimney is failing and leaking dangerous gases into your home: - Gas-like odor near the fireplace: A strong, sweet, or rotten-egg smell (often from burning creosote or natural gas mixing with air) is your first warning. - Headaches or dizziness after using the fireplace: CO poisoning causes flu-like symptoms, nausea, fatigue, or confusion, especially in older adults or children. - Soot inside the house or on the chimney cap: Black streaks on the cap or inside the room mean incomplete combustion, a sure sign of a leak. - Yellow or flickering flames instead of blue: A healthy fire burns blue. Yellow or orange flames indicate poor airflow and CO buildup. - Stale or stuffy air when the fireplace is lit: If smoke or gases can’t escape, they’ll seep into your living space.
Murfreesboro’s older homes often have single-wall masonry chimneys (no liner), which are prone to cracks. If you’ve noticed rust around the damper or cracks in the brickwork, your chimney is already compromised. The EPA’s Burn Wise program the EPA's Burn Wise program recommends installing a carbon monoxide detector near sleeping areas and 10 feet from any fireplace or stove, but don’t rely on it alone. A professional inspection is the only way to confirm a leak before it’s too late.
Why Murfreesboro’s older brick chimneys fail, and how to fix it
Most carbon monoxide leaks in Murfreesboro start with one of these three issues: 1. Cracked or missing chimney liners: Older homes often have clay tiles that erode over time. If the liner cracks, gases escape into the masonry, and your home. Stainless-steel liners last longer but can corrode if not properly installed. 2. Damaged masonry: Murfreesboro’s freeze-thaw cycles (especially in winter) and high humidity weaken mortar joints. A collapsed crown or crumbling bricks create gaps where CO seeps out. 3. Blocked flues: Creosote buildup, bird nests, or debris (like leaves from nearby oak trees) restrict airflow, forcing gases back into the house.
The fix? A Level 2 chimney inspection (which checks inside the flue and smoke chamber) followed by relining or masonry repairs if needed. The CSIA recommends this for homes with visible cracks, rust, or soot outside the chimney. If your chimney is over 30 years old and has never been relined, it’s a ticking time bomb, especially in Murfreesboro’s climate. Juan Rodriguez Chimney LLC specializes in restoring older brick chimneys and can assess whether your system needs a stainless-steel liner, crown repair, or full masonry restoration before winter makes the problem worse.
You smell gas when you strike a match, don’t wait for symptoms to worsen. Here’s the exact step-by-step to handle a chimney CO leak safely.
If you smell gas, feel sick, or see soot near your fireplace, do not panic, but act fast: 1. Evacuate immediately and call 911. CO poisoning can be fatal within minutes. 2. Do not re-enter until emergency responders confirm it’s safe. 3. Call a professional chimney sweep, not just any handyman. A certified sweep can perform a smoke test to check for leaks and identify the source (cracked liner, blocked flue, or masonry failure). 4. Turn off the fireplace or stove and keep vents closed until inspected. 5. Schedule a Level 2 inspection (which checks the flue and smoke chamber) to rule out hidden damage.
Murfreesboro’s older homes often have hidden issues, like a collapsed liner behind intact brickwork. A visual inspection won’t catch them. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) states that 90% of chimney fires start with undetected blockages or cracks, so don’t wait for symptoms. If your chimney is over 20 years old, get it inspected before winter, when CO leaks become deadly. Juan Rodriguez Chimney LLC offers free estimates for emergency inspections and can often complete repairs within 24–48 hours.
How often should you check for carbon monoxide leaks in Murfreesboro?
The CSIA recommends annual inspections for homes that use their fireplace regularly, but Murfreesboro’s climate demands more frequent checks if you have an older brick chimney: - Before the first fire of the season: Humidity and summer storms can weaken masonry overnight. - After any major weather event: High winds or ice can crack chimney caps or dislodge bricks. - If you notice changes in flame color or smell gas: Don’t wait, schedule an inspection immediately. - Every 5–7 years for a full masonry and liner check: Even if nothing seems wrong, creosote buildup and mortar erosion happen silently in Murfreesboro’s damp air.
If your home is in a high-risk area (like near Old Fort Park or Stone’s River National Battlefield, where older homes dominate), consider bi-annual inspections, spring and fall. The U.S. Environmental Protection Agency the U.S. Environmental Protection Agency notes that older homes with unlined chimneys are 3x more likely to leak CO than newer ones with stainless-steel liners.

Can a chimney sweep prevent carbon monoxide leaks in Murfreesboro?
Yes, but only if they do more than just clean. A proper chimney sweep should: - Inspect the liner for cracks, rust, or separation from the masonry. - Check the crown and flashing for gaps where CO could escape. - Test for blockages using a smoke puff test or camera inspection. - Assess the masonry for crumbling bricks or mortar failure (common in Murfreesboro’s older homes).
What a basic sweep won’t catch: Hidden cracks in the liner, collapsed mortar joints, or a partially blocked flue. That’s why the CSIA certifies sweeps to perform Level 1 and Level 2 inspections, the only way to confirm your chimney is safe. If your sweep only cleans and doesn’t inspect, you’re gambling with your family’s safety. Juan Rodriguez Chimney LLC uses CSIA-certified technicians who perform full diagnostic inspections during every cleaning, so you know your chimney is leak-free before you light another fire.
Murfreesboro chimney emergency costs: What to expect
The cost of fixing a CO-leaking chimney depends on the damage, but here’s what Murfreesboro homeowners typically pay: - Emergency inspection: $120–$200 (includes smoke test and visual assessment). - Liner repair or replacement: $800–$2,500 (stainless-steel liners last 20+ years and prevent leaks). - Masonry repairs: $500–$3,000 (depends on brickwork damage; older homes often need full repointing). - Crown or cap replacement: $200–$600 (a cracked crown is a top CO leak source in Murfreesboro).
The good news: Fixing a small crack or blockage now costs far less than treating CO poisoning or dealing with a chimney fire. The NFPA reports that chimney fires cause $125 million in damages annually, and that’s before medical bills from CO exposure. Juan Rodriguez Chimney LLC offers transparent pricing and can often complete emergency repairs within 48 hours to get your home safe before winter. If you’re in Smyrna, La Vergne, or Franklin, we also serve those areas with the same emergency response.

Frequently Asked Questions
Lighting your gas fireplace in your Southside bungalow triggers a sharp chemical smell, should you keep burning, or is this a liner leak waiting to happen?
No, that’s not normal and means your chimney is leaking unburned fuel gases, likely carbon monoxide. The smell comes from incomplete combustion due to a blocked flue, cracked liner, or poor draft. Evacuate immediately, call 911, and don’t re-enter until a professional confirms it’s safe. Murfreesboro’s older brick chimneys often have hidden cracks that let gases escape into the house. Learn the 7 critical signs your chimney is leaking CO before it’s too late.
I feel dizzy every time I use my fireplace, could it be carbon monoxide?
Yes, dizziness, headaches, or nausea after using the fireplace are classic signs of low-level CO poisoning. Since CO is odorless, you might not realize it’s coming from your chimney until symptoms appear. Install a CO detector near your fireplace and schedule a Level 2 inspection, this checks the flue and smoke chamber for cracks or blockages. Murfreesboro’s humid summers accelerate liner deterioration, so if your chimney is over 20 years old, it’s at high risk. Call us for an emergency inspection before your next fire.
My chimney cap has black streaks, does that mean I’m leaking carbon monoxide?
Black streaks on the chimney cap usually mean soot buildup, but they can also signal incomplete combustion, a warning sign of a CO leak. If the soot is thick, tar-like, or accompanied by a strong odor, your chimney isn’t venting properly. Soot outside the cap often means a blocked flue or cracked liner, both of which can let CO into your home. Don’t ignore it. Murfreesboro’s older brick chimneys are prone to these issues, especially after winter freeze-thaw cycles. A professional sweep can clean the flue and check for hidden damage before it becomes an emergency.
How do I know if my Murfreesboro chimney liner is cracked and leaking CO?
You can’t see a cracked liner from outside, but watch for these signs: - Rust around the damper or stove pipe (CO reacts with metal). - Yellow/orange flames instead of blue (poor combustion = CO buildup). - Soot inside the house (means gases aren’t escaping). - A musty or stale smell when the fireplace is lit (CO mixing with air). The only way to confirm is a Level 2 inspection with a smoke test or camera scope. Murfreesboro’s older homes often have clay tile liners that crack over time, stainless-steel liners are the only long-term fix. Find a CSIA-certified sweep in your area who can inspect your liner before winter makes the problem worse.
