A chimney inspection in Everett isn’t just about creosote buildup, it’s a carbon monoxide & smoke test to catch hidden dangers like cracked liners, blocked flues, or failing masonry. If your fireplace smokes, smells, or your home’s air quality drops, schedule a sweep now before winter. Older brick homes near Everett’s waterfront (like those in the Everett Waterway area) are especially vulnerable to moisture damage that weakens chimneys over time. The Chimney Safety Institute of America recommends annual inspections for homes with fireplaces, but Everett’s damp climate can accelerate wear, so don’t wait for a visible problem.
1. What Is a Carbon Monoxide & Smoke Test, and Why Does Your Everett Chimney Need It?
A carbon monoxide & smoke test is a professional chimney inspection that checks for two critical hazards: toxic gas leaks and poor draft/ventilation. In Everett, where older brick homes (especially those built before the 1980s) often lack modern chimney liners, these tests reveal problems you can’t see, like cracks in masonry, corroded flue tiles, or a blocked chimney from years of creosote buildup. The test works by introducing a harmless smoke puff into the fireplace while measuring CO levels and airflow. If smoke spills into your home or CO registers above safe levels, your chimney isn’t venting properly, meaning deadly gas could be leaking during fires. Everett’s humid summers and rainy winters make this especially risky: moisture seeps into brickwork, eroding mortar and creating gaps that let CO escape. The National Fire Protection Association (NFPA) reports that most chimney fires start from undetected creosote or structural flaws, and a smoke test catches those before they ignite. Schedule a chimney sweep in Everett to run this test before your first winter fire.
2. Your Everett Fireplace Smokes Even When Lit. Here’s What It Means (And How to Fix It)
If your fireplace smokes while burning, not just when you first light it, your chimney has a draft problem. In Everett, this often happens in older homes with unlined brick chimneys or those near the waterfront (where humidity accelerates mortar deterioration). Smoke backing up into your home means one of three issues: - Blocked flue: Creosote buildup, bird nests, or debris (like fallen leaves from Everett’s windy autumns) can clog the chimney. A chimney sweep clears this out. - Cracked liner or masonry: Everett’s freeze-thaw cycles (common in winter) can crack brickwork or liners, letting smoke escape sideways. A smoke test will show where the leak is. - Improper sizing: Older Everett homes often have chimneys too small for modern fireplaces. The EPA’s Burn Wise program notes that a chimney should be at least 3 inches wider than the flue pipe, otherwise, smoke can’t escape efficiently. Fixing this requires a professional inspection to identify the root cause. DIY fixes (like adding more wood) just mask the problem, until CO poisoning becomes a risk. Learn about Everett chimney liner repairs if your home has an older, unlined chimney.
3. You Smell Gas or Rotten Eggs Near the Fireplace. This Isn’t Normal (And It’s Dangerous)
A strong, acrid smell (like sulfur or rotten eggs) near your fireplace after lighting it means carbon monoxide or gas is leaking. In Everett, this often happens in homes with: - Cracked or missing chimney caps: Wind and rain (especially during Everett’s stormy winters) can dislodge caps, letting water and debris enter the flue. This corrodes the liner and creates gaps for CO to escape. - Improperly installed stoves or inserts: Older Everett homes sometimes have wood stoves retrofitted without proper clearance to combustible materials, causing incomplete combustion and gas buildup. - Faulty seals: Gaskets around glass doors or stove pipes can degrade over time, letting CO seep into your home. What to do: Turn off the fireplace immediately, open windows, and evacuate if you feel dizzy or nauseous (CO symptoms). Then call a licensed chimney sweep to perform a carbon monoxide & smoke test. The U.S. Environmental Protection Agency warns that CO is odorless and colorless, so if you smell it, the leak is already serious. Everett dryer vent cleaning can also cause CO if lint blocks airflow, but a fireplace smell requires urgent chimney attention.
4. Your Chimney Leaks Water. Even If It’s Not Raining (A Hidden Everett Problem)
Water stains on your ceiling or walls near the fireplace aren’t just cosmetic, they’re a sign of a failing chimney. In Everett, where annual rainfall averages 40 inches, moisture is the #1 enemy of brick chimneys. Here’s how it happens: - Missing or damaged chimney caps: Without a cap, rain pours directly into the flue, eroding mortar and rusting metal liners. Over time, this creates cracks that let CO escape. - Cracked crown or masonry: Everett’s freeze-thaw cycles (common in winter) cause bricks to expand and contract, leading to hairline fractures. These may not leak water yet, but they compromise the chimney’s structure and allow gas to bypass the flue. - Poor flashing: If the metal flashing around your chimney is rusted or improperly sealed (a common issue in older Everett homes), water seeps behind the bricks, weakening them. Solution: A chimney waterproofing inspection paired with a smoke test will reveal hidden damage. Ignoring leaks leads to structural collapse risks, and in Everett’s rainy climate, this happens faster than in drier areas. See our guide on Everett chimney waterproofing for steps to protect your brickwork.
5. Your Fireplace Burns Slowly or Goes Out Unexpectedly. This Means Poor Airflow
If your fire struggles to stay lit or smolders instead of burning hot, your chimney isn’t drawing air properly. In Everett, this is often due to: - Creosote buildup: Thick, tar-like creosote (common in older, unlined chimneys) clogs the flue, restricting airflow. The Chimney Safety Institute of America (CSIA) warns that 1/8-inch of creosote can reduce draft by 50%. - Obstructions: Birds, squirrels, or even Everett’s windy autumn leaves can block the flue. A chimney sweep removes these blockages. - Down-drafting: Everett’s coastal winds can push smoke down the chimney instead of up, especially in tall, unlined brick chimneys. This is why chimney caps with wind-resistant designs are critical here. Fix it: A smoke test will confirm if your chimney is drawing properly. If not, you may need a chimney liner upgrade or draft inducer to improve airflow. Older Everett homes often need specialized chimney repairs, learn more.
6. Your Chimney Is Older Than Your House (And You’ve Never Had It Inspected)
If your Everett home was built before the 1970s, your chimney likely has no liner, just bare brick. While brick chimneys are durable, they’re not designed to handle modern fireplaces or the high-heat outputs of today’s wood stoves. Here’s why this is risky: - No protection from heat: Unlined chimneys absorb heat, causing thermal stress cracks that let CO escape. - Creosote buildup accelerates: Without a liner, creosote sticks to rough brick surfaces, creating a highly flammable layer that can ignite into a chimney fire. - Mortar deterioration: Older mortar (especially in Everett’s damp climate) crumbles over decades, leaving gaps for gas to leak. Action step: Schedule a carbon monoxide & smoke test immediately. If your chimney is unlined, you’ll need a stainless steel liner installed before winter. Everett historic brick chimneys require specialized care, see our techniques to avoid damaging your home’s character.
7. You Hear Strange Noises (Popping, Crackling, or Whistling) When the Fireplace Is Off
Unusual sounds from your chimney when the fireplace is cold signal structural issues. In Everett, these noises often mean: - Cracked flue tiles: The popping sound is brick or tile shifting due to moisture expansion (common after Everett’s rainy winters). - Loose or missing chimney cap: A whistling noise can mean wind rushing through gaps in a damaged cap. - Animal activity: Squirrels or birds nesting in your chimney create scratching or scurrying sounds. A chimney sweep will remove them, and check for damage they may have caused. Don’t ignore it: These noises can escalate into chimney collapses or CO leaks. A smoke test will pinpoint the source. Everett’s older homes need regular chimney checks, here’s how often to catch these issues early.

Frequently Asked Questions
My Everett chimney passed a smoke test last year, do I need another one this year?
Yes. The Chimney Safety Institute of America (CSIA) recommends annual inspections for homes that use their fireplaces regularly. Everett’s climate, with its humid summers and rainy winters, accelerates wear on chimneys, especially older brick ones. A test from last year doesn’t account for new cracks, creosote buildup, or seasonal damage. If you’ve had no fires since last winter, a biennial inspection may suffice, but schedule a carbon monoxide & smoke test if you notice any changes in draft or smell.
Can I do a DIY carbon monoxide test for my Everett chimney?
No. Portable CO detectors only measure room air, they won’t detect leaks inside the chimney flue. A professional carbon monoxide & smoke test uses specialized equipment to trace gas flow through the chimney system. In Everett, where older homes often have hidden masonry cracks, a DIY test misses critical risks. The NFPA warns that improper testing can give false negatives, leading homeowners to believe their chimney is safe when it’s not. Learn why DIY chimney work is risky in Everett.
My Everett chimney is made of brick, do I still need a smoke test if it looks fine?
Absolutely. Brick chimneys hide damage until it’s severe. In Everett, moisture from rain and humidity seeps into mortar, causing cracks that aren’t visible from the outside. A smoke test reveals: - CO leaks through microscopic gaps in the brickwork. - Poor draft due to creosote or obstructions you can’t see. - Structural weaknesses from freeze-thaw cycles (common in winter). The CSIA states that even well-maintained brick chimneys need annual testing, especially in areas with high humidity like Everett. See how Everett’s climate affects brick chimneys.
How much does a carbon monoxide & smoke test cost in Everett?
In Everett, a basic carbon monoxide & smoke test typically costs $120–$200, depending on chimney height and access. If your chimney has no liner or visible damage, the test alone may reveal hidden issues requiring repairs (like liner installation or masonry work), adding $500–$2,000+ to the total. Many Everett homeowners bundle this with a chimney sweep ($150–$300) to clear creosote and debris at the same time.
