Before climbing on your roof, start with these safe checks to spot common Lacey chimney issues. If you see red flags, stop and call a licensed pro—your safety depends on it.
Step 1: Check the flue cap and screen from the ground
From a safe distance on the ground, use binoculars to inspect your chimney’s flue cap and screen. Look for rust, cracks, or missing pieces—especially important in Lacey’s damp climate where corrosion happens faster. A damaged cap lets rain, birds, and debris enter, clogging your flue and damaging the liner. If the screen is torn or the cap is loose, do not climb onto the roof. Instead, contact us for a quick repair before lighting your next fire. Even a small gap can lead to costly water damage in older Lacey homes with historic brickwork.
Step 2: Look for smoke or odor issues during your first Lacey winter fire
When you light your first fire of the season in your Lacey home, watch the smoke. If it billows into the room instead of drafting up the chimney, your flue may be blocked or improperly sized for your stove. A musty or acrid smell coming from the fireplace can also signal trapped moisture or creosote buildup—a common issue in older masonry chimneys. If smoke lingers or smells persist after a few minutes, extinguish the fire safely and avoid using the fireplace until a pro inspects it. Never ignore these signs—they can indicate a dangerous blockage or cracked flue liner.
Step 3: Inspect the mortar joints and bricks around your Lacey chimney
Stand back and examine the mortar joints and bricks on your chimney’s exterior. In Lacey’s older neighborhoods, you’ll often find historic brickwork with soft, crumbling mortar. Use binoculars to spot loose bricks, cracks wider than a credit card, or white efflorescence (salt deposits) on the bricks—signs of water intrusion. If you see any of these, do not attempt to repoint the mortar yourself. Older masonry requires specialized tools and materials to match historic lime mortar. Instead, contact us for a professional assessment and restoration quote.
Step 4: Test the damper operation from inside your fireplace
With the fireplace cold, open and close the damper lever to ensure it moves freely and seals tightly when closed. A damper that sticks or doesn’t close fully can let cold air into your Lacey home or allow smoke to backdraft into the room. If the damper is rusted shut or the seal is broken, do not force it. Forcing a stuck damper can crack the flue liner or dislodge bricks. Instead, contact us for a damper repair or replacement—especially important in older homes where the damper may be original and prone to failure.
Warning signs: Stop DIY and call a pro immediately
If you notice any of these warning signs, stop all DIY attempts and call a licensed chimney sweep right away. Cracks wider than a credit card in the chimney crown or flue liner can lead to structural failure or carbon monoxide leaks. A chimney that leans more than 2 inches from vertical is a critical safety hazard and requires immediate attention. Black soot or white powder (efflorescence) on the exterior bricks indicates water damage that can weaken the entire structure. If you see any of these, do not use your fireplace or wood stove until a professional inspects it. contact us for an emergency inspection in Lacey or one of our nearby service areas like Olympia, Tumwater, or Yelm.

Frequently Asked Questions
My Lacey chimney smells like mildew every time I light a fire—what’s causing this and is it dangerous?
A musty smell usually means moisture is trapped in your flue or masonry, often due to a damaged cap or cracked flue liner. In Lacey’s damp climate, this can lead to mold growth and weakened bricks. It’s not immediately dangerous but can worsen over time. Have a pro inspect your chimney and consider a waterproofing treatment or liner repair.
Why does my Lacey fireplace smoke back into the room when I light a fire, even though it worked fine last year?
Smoke backdrafting often points to a blocked flue, improper damper operation, or negative indoor air pressure. Lacey’s older homes can develop creosote buildup or cracked liners that disrupt draft. Check for obstructions first, but if the issue persists, call a pro—your chimney may need cleaning or relining to restore proper airflow.
Can I just patch the cracks I see in my Lacey chimney’s mortar myself, or is that a job for a pro?
Never DIY mortar repairs on an older Lacey chimney. Historic lime mortar requires special tools and materials to match the original. Modern Portland cement can trap moisture and cause more damage. Instead, call us for a professional assessment and restoration using compatible materials to preserve your home’s brickwork and value.
