Before climbing on your roof, run through this Durham-specific checklist to spot minor issues safely. If you see these warning signs, stop and call a licensed sweep—chimney work isn’t a DIY job.
Step 1: Check the Exterior for Obvious Damage
Stand back and look up at your chimney from the ground in Durham’s morning light. Cracked bricks, leaning sections, or missing mortar near the crown are red flags. Use binoculars if the stack is tall. If you spot damage, don’t attempt repairs yourself—brickwork and mortar require specialized tools and masonry skills. Instead, note the location and call Matts & Sons Chimney for a professional assessment. Even small cracks can let water in, and Durham’s freeze-thaw cycles turn them into major problems fast.
Step 2: Inspect the Chimney Cap and Crown
A damaged cap or cracked crown lets rain, debris, and animals into your flue. From the ground, check for a missing or tilted cap and look for white, powdery stains on the crown—signs of water damage. If the cap is missing or the crown is cracked, don’t climb onto the roof to replace it. These components are critical for preventing water intrusion and downdrafts. Schedule a repair with a pro before your next burn. Learn more about cap and crown care in our Chimney Cap & Crown Repair guide.
Step 3: Test the Flue for Obstructions
Turn off your furnace and fireplace, then shine a bright flashlight up the flue from the firebox. Look for bird nests, leaves, or creosote buildup. If you see debris, don’t poke at it with a stick or broom handle—you could dislodge it and block the flue completely. Instead, use a shop vacuum with a long hose attachment from the firebox side to safely remove loose debris. For stubborn blockages, call a pro. Need a refresher on safe tools? Check our Durham Chimney Safety Inspection guide.
Step 4: Monitor Smoke and Smell Inside the House
Light a small, safe fire in your Durham fireplace and watch how smoke exits the chimney. If smoke blows back into the room or you smell a strong, acrid odor, your flue may be blocked or improperly sized. Don’t ignore this—it’s a carbon monoxide risk. Open windows for ventilation and avoid using the fireplace until a pro inspects the system. For more on smoke issues, read our Durham Chimney Warning Signs guide.
Step 5: Check the Damper Operation
Open and close the damper a few times to ensure it moves freely and seals tightly when closed. A stuck or broken damper won’t control airflow, leading to heat loss or downdrafts. If the damper is rusted or won’t budge, don’t force it—you could damage the flue liner. Lubricate the mechanism with a graphite-based spray if it’s stiff, but replace it if it’s broken. Need help?

Warning Signs: Stop DIY and Call a Pro Immediately
If you notice any of these signs, stop troubleshooting and call a licensed chimney sweep in Durham right away: visible cracks in the flue liner, white efflorescence on bricks, a strong sulfur smell (rotten eggs), soot or debris falling into the firebox, or a chimney that leans more than an inch from vertical. These issues can cause chimney fires, carbon monoxide leaks, or structural collapse. Never attempt to repair liners, crowns, or masonry yourself—hire a pro with CSIA certification.

Frequently Asked Questions
How much does a chimney inspection cost for a typical Durham home in 2025?
A Level 1 chimney inspection in Durham averages $120–$180, while a Level 2 inspection (required after major renovations or if you’ve had a chimney fire) runs $200–$350. Prices vary based on flue type and accessibility. For a full breakdown, see our How Much Does a Chimney Sweep Cost in Durham, CT: A Safety-First Guide.
Can I burn wood in my Durham fireplace after a chimney cleaning, or should I wait?
You can safely burn wood immediately after a professional cleaning, but wait 24 hours after a Level 2 inspection to ensure no residual moisture or sealants affect your fire. If your chimney hasn’t been cleaned in over a year, schedule a sweep before your first burn to prevent creosote fires. Learn more in our Durham Chimney Safety Inspection guide.
How often should I schedule a chimney sweep for my Durham home if I use it weekly in winter?
Durham homeowners who burn wood weekly should schedule a chimney sweep every 12 months, or more often if you notice thick creosote buildup. If you use gas logs, an annual inspection is still recommended to check for debris or animal nests. For a seasonal schedule, read our How Often Should You Service Your Chimney?
