When your Lynnwood chimney starts acting up, start with these safe checks first. But know your limits—some problems demand a pro’s trained eye and tools. We’ll show you what you can safely inspect and when to call David Chimney.
Step 1: Check the exterior brickwork for Lynnwood’s weather damage
Older Lynnwood homes often have brick chimneys that show their age. Walk outside and look for cracked, loose, or missing bricks—especially after winter’s freeze-thaw cycles. Also check the mortar joints for gaps or crumbling. If you spot damage larger than a quarter, stop here. Climbing ladders or poking mortar with tools can worsen cracks or cause bricks to shift. Instead, take a photo and contact us for a free inspection. We specialize in masonry repairs for homes built before 1980, common in Lynnwood’s older neighborhoods near Alderwood Mall.
Step 2: Inspect the chimney cap and crown from the ground
Use binoculars to check the chimney cap and crown from your yard. Look for rust on the cap, cracks in the crown, or debris blocking the flue. A missing or damaged cap lets rain, birds, and leaves into your chimney—accelerating wear in Lynnwood’s damp climate. If the cap is loose or the crown has spiderweb cracks, don’t try to fix it yourself. A DIY fix can void warranties or worsen leaks. Instead, schedule a chimney inspection to assess liner and cap condition before winter.
Step 3: Test the damper operation from inside your fireplace
Light a flashlight and open your fireplace damper. It should move smoothly and stay open. If it sticks, squeaks, or won’t stay open, don’t force it. Older dampers in Lynnwood homes often warp from heat and moisture. Forcing a stuck damper can crack the flue liner or dislodge bricks. Instead, try a graphite spray lubricant on the hinge—but only if you’re comfortable. If it still won’t budge, call us to inspect the damper and liner before your next burn.
Step 4: Look for creosote buildup with a mirror and flashlight
Shine a flashlight up the flue from the fireplace opening. Use a small mirror on a stick to see inside. Heavy black, tarry creosote or thick layers of brown, flaky buildup mean it’s time for a sweep. But don’t climb on the roof or use tools to scrape it—old chimneys in Lynnwood can have weakened masonry that collapses under weight. Instead, note the thickness and request a quote for a Level 2 inspection. We’ll measure creosote depth safely and recommend cleaning or liner repair.
Step 5: Watch for smoke and odor clues after burning
After your next fire, watch how smoke exits the chimney. Does it billow back into the room? Does a strong, acrid smell linger for hours? These are signs of poor draft or a blocked flue—common in Lynnwood homes with tall trees or nearby hills that disrupt airflow. Don’t ignore it. A blocked flue can force carbon monoxide into your home. Instead, open a window and schedule a Level 1 inspection to check for obstructions or liner damage before lighting another fire.
Warning signs that mean stop and call a pro immediately
Some chimney issues in Lynnwood are silent killers. If you see white, chalky stains on bricks (efflorescence), hear a rumbling sound during wind, or notice soot falling into the fireplace, stop all DIY. These signs often point to water damage, cracked liners, or deteriorating masonry that could collapse. Also, if your carbon monoxide detector alarms during fireplace use, evacuate and call 911. Never use the fireplace again until a pro inspects it. Learn more about warning signs and when to act.

Frequently Asked Questions
Should I try to repair cracked mortar on my Lynnwood chimney myself?
No. Older Lynnwood homes often have soft, crumbly mortar that’s unsafe to patch without proper tools and training. A DIY repair can trap moisture, accelerate brick decay, or void insurance. Instead, call us for a masonry assessment. We use tuckpointing techniques that match historic mortar and prevent future leaks.
Is it worth cleaning my chimney if I only use my fireplace a few times a year in Lynnwood?
Yes. Even occasional use in Lynnwood’s damp climate builds creosote and traps moisture, leading to liner damage and mold. A yearly inspection is cheap insurance. See our pricing guide for Lynnwood homeowners. We recommend cleaning if creosote is thicker than 1/8 inch—even with light use.
Do I really need a chimney liner in my older Lynnwood home?
Absolutely. Many Lynnwood homes built before 1980 have unlined chimneys or damaged clay tiles. A liner protects your home from heat transfer, prevents carbon monoxide leaks, and improves draft. Learn about liner options and why they’re critical for older masonry.
