In Murfreesboro’s older brick homes, chimney damage often hides in plain sight: hairline cracks in mortar near the roofline, white efflorescence on bricks after summer storms, or a musty smell in the fireplace room. Addressing these early—before winter’s first burn—can prevent a $2,000+ rebuild.
A chimney inspection is a non-negotiable first step for Murfreesboro’s older brick homes
A chimney inspection is a thorough visual and instrumental assessment of your flue, liner, masonry, and flashing to identify damage, blockages, or safety hazards. In Murfreesboro, where many homes were built before 1980 and feature unreinforced masonry, even minor cracks in the crown or shifting bricks can signal deeper structural issues. The Chimney Safety Institute of America recommends annual inspections, but in older neighborhoods like historic downtown or the College Heights area, bi-annual checks are wise due to seasonal temperature swings and humidity. A certified sweep will use a camera to inspect the flue and check for creosote buildup, cracks in the tile liner, or gaps in the mortar joints. If you’ve owned your home in Murfreesboro for over 10 years without an inspection, schedule one now—especially if you’ve noticed drafts or soot buildup. Learn what to expect during your inspection
Check your chimney crown and flashing for cracks before Murfreesboro’s summer storms hit
The chimney crown is the concrete or mortar cap at the top of your chimney; in Murfreesboro’s older homes, it’s often cracked or missing chunks due to freeze-thaw cycles. Walk outside after a rain and look for water stains on the bricks below the crown or white efflorescence (salt deposits) on the masonry. These are signs water is seeping in, which can erode mortar and rot wooden framing inside the chase. Flashing—the metal seal between the chimney and roof—is another weak point; if it’s lifted, corroded, or missing sealant, water can pool and cause rot in your attic or ceiling near the chimney chase. A quick DIY check: shine a flashlight along the crown’s edge and use binoculars to inspect flashing from the ground. If you spot gaps larger than a credit card, call a sweep before the next storm. Murfreesboro’s summer storms can worsen hidden leaks—don’t wait
Listen for drafts and smell for mustiness: Murfreesboro’s indoor clues to chimney trouble
If your fireplace room smells musty when the flue is closed, or you feel a draft from the chimney even when the damper is shut, your chimney may have a cracked flue liner or a disconnected section. In older Murfreesboro homes with brick chimneys built before modern liners, the clay tile liners often crack over time, allowing smoke, carbon monoxide, and cold air into your home. A persistent campfire smell in summer or soot dust on furniture near the fireplace are also red flags. Don’t ignore these signs—carbon monoxide is odorless and deadly. The National Fire Protection Association warns that damaged liners are a leading cause of chimney fires. If you notice these symptoms, especially in homes near the Stones River or in the historic district, schedule an inspection immediately. Don’t gamble with indoor air quality—get a free estimate
Brickwork and mortar: How to spot shifting and cracks in Murfreesboro’s older chimneys
In Murfreesboro’s pre-1980 brick chimneys, hairline cracks in the mortar joints or bulging bricks are common but dangerous. Walk around your chimney and look for stepped cracks (diagonal cracks that follow mortar lines) or bricks that protrude outward—these indicate the chimney is leaning or separating from the house. Another telltale sign is loose bricks in the firebox or hearth area, which can fall into the flue and block airflow. If you see white, powdery deposits on the bricks (efflorescence), it means water is dissolving the lime in the mortar and weakening the structure. Older chimneys in neighborhoods like Oakland or the Cannonsburgh area often show these issues due to age and seasonal temperature swings. Addressing cracks early can save you from a full rebuild, which can cost $3,000–$7,000 in Murfreesboro. See how we restore historic masonry safely
Creosote buildup in Murfreesboro’s wood-burning fireplaces: The silent efficiency killer
Creosote is a black, tar-like residue that builds up inside your flue when burning wood, and it’s a major fire hazard in older Murfreesboro homes with unlined or cracked chimneys. If you burn pine or softwoods, creosote accumulates faster—especially in homes near the Rutherford County Fairgrounds, where humidity is higher. Signs of creosote buildup include a strong campfire smell when the flue is closed, black soot falling into the firebox, or a thick, shiny glaze inside the flue. The Chimney Safety Institute of America recommends cleaning when creosote reaches 1/8 inch or more. Ignoring this can lead to chimney fires, which are more common in older, unlined flues. If you haven’t cleaned your chimney in over a year, schedule a sweep now—especially before the first cold snap in November. Learn how often to clean based on your wood type
Murfreesboro’s seasonal humidity and temperature swings: How they accelerate chimney damage
Murfreesboro’s climate—hot summers, mild winters, and high humidity—is tough on older chimneys. In summer, moisture seeps into cracks in the crown, mortar, and bricks, then freezes in winter, expanding and widening the gaps. This cycle can cause bricks to spall (chip or flake) and mortar to crumble. Homes near the Stones River or in low-lying areas like the Jones Boulevard corridor are especially vulnerable. Another local issue: older chimneys often lack proper cricket flashing (a peaked metal shield behind the chimney), which directs water away from the roof. Without it, water pools and seeps into the chimney chase, rotting wooden framing. If your chimney is exposed to direct sun or sits on a south-facing roof, the heat can also dry out mortar and cause it to crack.

When to call a professional: Murfreesboro’s red flags that demand immediate action
Some chimney issues in Murfreesboro’s older homes are emergencies. If you see bricks falling into the firebox, a chimney leaning visibly, or smoke backing up into the room when the damper is open, stop using the fireplace immediately and call a professional. Other urgent signs include a collapsed flue liner, a missing or severely damaged chimney cap, or water dripping into the firebox during rain. These problems can lead to structural failure, carbon monoxide leaks, or chimney fires. Even if the damage seems minor, older chimneys in Murfreesboro’s historic districts or pre-1980 neighborhoods often hide unseen issues. A certified sweep can assess the damage and provide a repair estimate, which may include tuckpointing, liner replacement, or crown repair. Don’t wait for a disaster—get a free estimate today

Frequently Asked Questions
What does white powder on my Murfreesboro chimney bricks mean after a rain?
That white powder is efflorescence—salt deposits left behind when water evaporates from bricks and mortar. In Murfreesboro’s humid climate, it’s a sign your chimney is absorbing water, which weakens mortar and can lead to cracks or spalling. Address it by sealing the chimney crown and repairing any cracks before winter.
Why does my Murfreesboro fireplace smell like a campfire in the middle of summer?
A persistent campfire smell in summer usually means creosote buildup in your flue is releasing trapped odors when humidity rises. Older, unlined chimneys in Murfreesboro’s pre-1980 homes are especially prone to this. A professional cleaning will remove the residue and eliminate the odor.
How can I tell if my Murfreesboro chimney liner is cracked without climbing on the roof?
Signs of a cracked liner include soot falling into the firebox, a strong campfire smell when the flue is closed, or smoke backing up into the room. If your chimney is older and you notice these issues, especially in homes near the Stones River, assume the liner is compromised and schedule an inspection.
What’s the cost range for repairing a cracked chimney crown in Murfreesboro?
Repairing a cracked chimney crown in Murfreesboro typically costs $300–$800, depending on the extent of the damage and whether the crown needs partial or full replacement. If the crack is small, a professional can patch it with hydraulic cement. For larger cracks or missing sections, a full rebuild may be needed, which can cost $1,000–$2,500.
