Durham’s summer heat and humidity can stress your chimney, increasing fire and carbon-monoxide risks. Start with safe, simple checks now to keep your hearth safe all season long.
Step 1: Inspect Your Chimney Cap and Crown Outside
Walk around your home and look up at the chimney top from the ground. Check that the chimney cap is secure and free of debris like leaves or pine needles—Durham’s summer storms can send branches flying. Inspect the crown for cracks or crumbling mortar; even small gaps let water in, damaging the flue and liner. If you see damage, mark it with painter’s tape and call a pro. Never climb onto the roof yourself; Durham’s steep pitches and uneven shingles are a fall risk. For a closer look, hire a professional to assess the crown and cap safely.
Step 2: Clear the Hearth and Check for Nesting Debris
Inside, remove ashes and debris from the firebox using a metal shovel and ash bucket. Wear gloves and a dust mask—Durham’s older homes often harbor old soot and mold. Look for signs of animal nests or droppings; squirrels and birds love chimneys in summer. If you find nesting material, do not light a fire until it’s removed—blocked flues cause deadly carbon monoxide buildup. For stubborn blockages, schedule a sweep to clear the flue and inspect for damage.
Step 3: Test the Damper Operation and Seal
Open and close the damper a few times to ensure it moves freely. A stuck damper can trap heat and moisture, accelerating creosote buildup. Check the seal around the damper frame for gaps; Durham’s humid summers can warp metal over time. If the seal is cracked or the damper won’t stay open, it’s time for repair. Avoid forcing it—you could bend the frame or dislodge the liner. For a precise fix, request a damper service from a licensed sweep.
Step 4: Check for Creosote and Soot Buildup
Use a bright flashlight to peer up the flue from the firebox. Creosote looks like black, tarry streaks or shiny, hardened deposits. Even a thin layer is a fire hazard, especially in Durham’s dry summer heat. If you see more than 1/8 inch of buildup, do not use the fireplace until it’s cleaned. Creosote removal requires specialized brushes and tools—attempting it without training risks pushing debris into the flue or inhaling toxic dust. Book a chimney cleaning before your next burn to stay safe.
Warning Signs: Stop DIY and Call a Pro
If you notice cracked flue tiles, white staining (efflorescence), or a strong campfire smell in your living room, stop all DIY work. These signs point to water damage, hidden cracks, or a failing liner—common in Durham’s older brick chimneys. Other red flags include rust on the damper, smoke backing up into the room, or soot falling into the firebox. These issues demand a certified inspection and repair to meet code and prevent chimney fires. Contact Matts & Sons immediately if you see any of these warning signs.

Frequently Asked Questions
How much does a Durham chimney sweep cost in summer 2025?
In Durham, a standard chimney cleaning averages $120–$250, depending on flue length and buildup. Summer appointments are often cheaper and easier to schedule than fall rush. For exact pricing, request a free quote—we’ll inspect your chimney and provide a transparent estimate before work begins.
Can I burn wood in my Durham fireplace after a summer chimney cleaning?
Yes, but wait 24 hours after cleaning to ensure the flue is completely dry. Durham’s humidity can cause residual moisture, so light a small, hot fire first to test draft and smell for any smoke leaks. If smoke enters the room or the damper won’t open fully, stop using the fireplace and call us for an inspection.
What’s the difference between a Durham chimney inspection and a cleaning?
A Level 1 inspection checks for visible damage and blockages using a flashlight and mirror—ideal for routine maintenance. A cleaning removes soot and creosote buildup. If your chimney hasn’t been inspected in over a year, schedule both to ensure safety and code compliance before summer storms arrive.
