Summer is the perfect time for Swarthmore homeowners to tackle simple chimney maintenance safely. A few minutes of upkeep now can prevent costly repairs and keep your older brick chimney working efficiently all year.
Why summer is the best time for Swarthmore chimney care
Swarthmore’s warm, dry summers give you a safe window to inspect and clean your chimney without the rush of fall. Older brick chimneys in Swarthmore often have mortar joints that expand and contract with temperature swings, so summer maintenance helps spot cracks before winter rain or snow worsens them. Use this season to clear debris, check for loose bricks near the crown, and ensure your flue liner is intact. Avoid climbing on a cold, wet roof—summer’s stable weather makes it easier to spot issues like spalling bricks or missing mortar on your 1920s-era chimney. Read our summer safety note for Swarthmore homeowners.
Safe DIY steps: Exterior chimney inspection and cleaning
Start with a ground-level inspection of your Swarthmore home’s chimney. Look for leaning bricks, cracked mortar joints, or missing chunks near the crown—common in older Swarthmore masonry. Use binoculars to scan the flue for obstructions like bird nests or fallen branches. For cleaning, wear gloves and safety glasses, then gently brush the exterior with a stiff-bristle brush to remove soot and algae. Never use a pressure washer; it can erode older mortar and push water into cracks. If you spot white efflorescence (salt stains), it’s a sign of water damage—note it for your professional sweep.

How to check your Swarthmore chimney’s crown and cap
The chimney crown is the concrete or mortar “hat” at the top of your Swarthmore chimney. Cracks here let water seep in, damaging bricks and liners. Use a flashlight to inspect the crown from the ground or a sturdy ladder (with a spotter). Look for hairline cracks or chunks missing from the edge. If the crown is crumbling, it’s a job for a pro—DIY patching with mortar won’t last in Swarthmore’s freeze-thaw cycles. A missing chimney cap? Replace it with a stainless-steel model to keep out debris and critters. See our full list of repair services.
Warning signs: Stop DIY and call a pro immediately
If you see black streaks (creosote) inside the flue, bulging bricks, or a strong campfire smell in your living room, stop all DIY work. These signs point to dangerous creosote buildup, a cracked liner, or a blocked flue—all fire hazards in older Swarthmore homes. Never attempt to chip away at creosote yourself; it’s highly flammable and can ignite during your next fire. Other red flags: white powdery stains (efflorescence), rust on the damper, or smoke backing up into the house. These issues require professional tools, certifications, and insurance—your safety depends on it. See why DIY cleaning isn’t always safe.

Maintenance habits that save Swarthmore homeowners money
Simple habits extend your chimney’s life and reduce repair costs. After summer maintenance, keep gutters clean to prevent water from overflowing onto the chimney. Trim nearby trees (like those along Swarthmore’s tree-lined streets) to stop branches from scratching the flue. Burn only seasoned hardwood in your fireplace to minimize creosote buildup. Check your chimney cap annually—if it’s missing or rusted, replace it to block pests and debris. These small steps protect your investment in an older Swarthmore home. Learn more cost-saving tips.
Frequently Asked Questions
My Swarthmore chimney has white stains on the bricks—what are they and should I worry?
Those white stains are efflorescence, a sign your chimney is absorbing water. In Swarthmore’s humid summers and freeze-thaw winters, this can weaken mortar and bricks over time. While not an emergency, it’s a warning to check your crown and flashing for cracks. If the stains spread or bricks start spalling, call a pro to reseal or repair the chimney before winter.
Why does my Swarthmore chimney smell like a campfire even when I’m not using it?
That campfire odor usually means creosote buildup inside your flue. Older Swarthmore chimneys often have rough, unlined flues that trap soot and odors. Burning softwoods or wet wood worsens the problem. A professional sweep can remove the buildup and install a liner to prevent future smells. Don’t ignore it—creosote is highly flammable.
Can I patch my Swarthmore chimney’s crown with DIY concrete?
No—DIY concrete patches won’t hold up in Swarthmore’s climate. The crown expands and contracts with temperature changes, causing cracks to reopen. A pro will use flexible, waterproof materials designed for chimneys. If your crown is crumbling, it’s a job for a licensed sweep to avoid water damage to your flue and bricks.
