If your Auburn home has an older brick chimney, a standard sweep isn’t enough. Our local team performs 7 critical checks—from crown cracks to liner gaps—before we even touch the flue. These steps prevent chimney fires, carbon monoxide leaks, and costly water damage in Covington’s damp winters.
1. Crown inspection: the first line of defense against Covington’s rain
A chimney crown is a chimney’s concrete or mortar cap that keeps water out of the flue and masonry. In Auburn and Covington, where winter rain and freeze-thaw cycles are relentless, a cracked or eroded crown lets water seep into the brickwork, freeze, and spall the face off your chimney. We start every older-home sweep by checking the crown for spider-web cracks, missing chunks, or a slope that pools water toward the flue. If the crown is beyond spot repairs, we recommend a full replacement before the next wet season. Auburn chimney sweep crews see this failure pattern most often on homes built before 1980, when modern crown mixes weren’t standard. tips/how-to-prepare-for-your-covington-chimney-appointment with a quick crown photo so we can prioritize the repair.
2. Flue liner assessment: gaps you can’t see from the living room
A chimney inspection is a visual evaluation of the flue’s condition, creosote buildup, and structural soundness. In older Auburn brick chimneys, the clay tile liner often has missing joints, cracked sections, or outright gaps where heat and gases escape into the adjacent masonry. We run a specialized camera up the flue to photograph every joint and crack. If we spot gaps wider than 1/8 inch, we flag them for a liner repair or reline—especially if you burn seasoned hardwood in your Covington fireplace. A compromised liner is a chimney fire waiting to happen; the Chimney Safety Institute of America recommends relining when gaps exceed 1/4 inch. services/ before your next burn season.

3. Mortar joint depth and repointing needs in Auburn’s older brick
Older brick chimneys in Auburn neighborhoods like Lakeland Hills and Lea Hill often have mortar joints that are soft, recessed, or missing entirely. We measure joint depth with a probe and check for eroded lime in the mix—a common issue in pre-1950 masonry. If joints are less than 3/8 inch deep, we schedule repointing to prevent water intrusion and restore structural integrity. Repointing costs in Covington typically run $12–$18 per square foot for labor and materials, depending on access and joint width. blog/covington-repairs-restoration-older-brick-chimney before the next storm season hits. Worth a look: book a visit or ask a question.
4. Creosote layer thickness: the hidden fire hazard in Covington fireplaces
Creosote is the tar-like residue that coats flue walls from burning wood. In older Auburn homes with slow-burning, resinous softwoods, creosote can build up in layers thicker than a credit card in a single season. We measure thickness with a calibrated probe; anything over 1/8 inch requires mechanical removal. The National Fire Protection Association warns that creosote layers thicker than 1/4 inch can ignite at 1,000°F, a temperature easily reached in Covington fireplaces. compare/chimney-sweeping-vs-inspection/ so you can change burning habits and reduce future buildup.

5. Chimney cap and spark arrestor: the $20 part that saves thousands
A chimney cap is a metal cover that sits atop the flue to block rain, animals, and embers. In Auburn, where raccoons and squirrels nest in flues every spring, a missing or damaged cap is a common failure point. We inspect the cap for rust, missing mesh, or a spark arrestor screen that’s torn or clogged with pine needles. Installing a new stainless-steel cap with 3/8-inch mesh costs $150–$300 in Covington, a fraction of the cost of a chimney fire or animal removal. areas/covington/ before the next nesting season. Read up on our towns we cover.
6. Smoke chamber and smoke shelf: where Covington’s damp air hides trouble
The smoke chamber is the tapered section above the firebox that funnels smoke into the flue. In older Auburn homes, this area often has rough, uneven brick surfaces that trap soot and promote creosote growth. We check for cracked bricks, missing mortar, and a smoke shelf that’s clogged with debris. A properly shaped smoke chamber with a smooth parging coat reduces turbulence and improves draft. If we find buildup or damage, we recommend parging repairs to restore efficiency and safety. blog/covington-inspections-assessments-7-key-checks-older-brick-c on every Covington inspection.
7. Clearance to combustibles: the 2-inch rule every Auburn homeowner must know
Clearance to combustibles is the minimum distance required between the chimney’s exterior and any wood framing, siding, or roofing. In older Auburn homes, original framing often encroaches within 2 inches of the chimney, violating the International Residential Code. We measure clearance with a laser and flag any violations for correction. If you have a zero-clearance fireplace, we recommend a UL-listed chimney enclosure or a stainless-steel chase cover to bring your home up to code. blog/chimney-sweep-maintenance-protecting-covington-home-value by addressing clearance issues before they become a fire hazard.

Can I burn pine in my Auburn fireplace after a chimney sweep, or should I switch fuels?
After a sweep, burning pine is safe only if your chimney passes a Level 1 inspection and your liner is intact. Pine creates more creosote than hardwood; the Chimney Safety Institute of America recommends burning only seasoned hardwood to reduce buildup. blog/covington-chimney-sweep-tips/ for safer burning habits.
What’s the difference between a sweep and an inspection for my Covington brick chimney?
A chimney sweep removes creosote and debris; an inspection evaluates the flue, liner, masonry, and clearances for safety and code compliance. The National Fire Protection Association recommends both annually. compare/chimney-sweeping-vs-inspection/ before your next visit.
