Chimney Sweep vs DIY: 6 Critical Signs You Need a Licensed Everett Chimney Expert Before Winter Hits

By Joel & Colin Chimney Inc Team · Updated October 27, 2026

If your chimney shows soot stains on the fireplace walls, a strong smoky smell when lighting fires, or visible creosote glaze inside the flue, call a licensed Everett chimney sweep immediately. DIY tools can’t remove heavy buildup safely, and Everett’s damp winters turn minor issues into fire hazards overnight. Always hire a pro for anything beyond a quick visual check, especially before your first winter fire.

1. A chimney inspection is a detailed, safety-certified check of your flue, liner, and chimney structure for cracks, blockages, or damage, done by a licensed pro using specialized tools. DIY ‘cleaning’ with a brush only scratches the surface and misses hidden risks like cracked masonry or creosote glaze.

Everett’s older homes, especially those near the waterfront or in neighborhoods like Alderwood, often have chimneys built with mortar that weakens when exposed to our wet winters. A proper inspection catches what you can’t see: hairline cracks in the flue liner, rusted damper issues, or even animal nests (a common problem after our mild winters). The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends an annual inspection before winter, but if you’ve noticed drafts or smoke spilling into your home, you’re already past due.

DIY tools like a stiff brush or vacuum won’t reach the upper flue where creosote glaze builds up like tar. This sticky residue is highly flammable and ignites at lower temperatures than dry creosote, meaning a single spark from your fireplace can turn your chimney into a fire hazard overnight. In Everett, where homes sit close together and wind funnels smoke between buildings, a chimney fire can spread faster than you think. If your inspection reveals glaze, a pro sweep is non-negotiable. Everett chimney sweep teams use rotating brushes and high-pressure air to dislodge it safely, then follow up with a chimney cap inspection to prevent future buildup.

2. Creosote glaze looks like black, glassy streaks inside your flue. If you see it, stop burning wood and call a chimney sweep in Everett immediately, this is stage 3 buildup, the most dangerous.

Creosote forms when wood smoke condenses on cool chimney walls, and Everett’s humidity turns it into a sticky nightmare. Stage 1 (soot) is manageable with DIY tools, but by stage 3, glaze, you’re looking at a chimney that could erupt into flames with just one spark. Glaze is thick, tar-like, and often found in older chimneys or those with poor draft (common in homes near Everett’s industrial zones where wind patterns disrupt airflow).

Here’s how to spot it without risking a fall: Use a flashlight and a chimney mirror (available at hardware stores) to peer up the flue. If you see shiny, glossy black streaks that don’t brush away easily, that’s glaze. Never attempt to scrape it yourself, it’s toxic when disturbed and can clog your lungs. A licensed Everett chimney sweep will use a motorized brush and protective gear to remove it, then assess whether your chimney needs a liner upgrade or crown repair to prevent recurrence. Everett chimney cap & crown repair is often part of the fix after glaze removal.

3. Your damper sticks, rusts, or won’t stay closed. A faulty damper lets cold air rush in, speeds up creosote buildup, and wastes fuel, costing Everett homeowners hundreds in wasted wood each winter.

Everett’s damp air turns metal dampers into rust traps, especially in older homes with cast-iron dampers. If yours sticks open or closed, or if you hear a loud clang when opening it, that’s a sign it’s warped or corroded. A stuck damper doesn’t just reduce efficiency, it creates negative pressure in your flue, pulling unburned gases into your home. The EPA’s Burn Wise program the EPA's Burn Wise program warns that this can expose you to carbon monoxide, a silent killer.

DIY fixes like WD-40 or sandpaper might seem to help, but rusted dampers often need replacement. A chimney sweep in Everett will inspect yours during a cleaning and recommend upgrades if needed. For example, homes in the Everett Heights area with brick chimneys often require stainless steel dampers to handle our climate. If your damper is beyond repair, a pro can install a new one during your sweep, saving you a separate service call later. Everett chimney sweep services include damper checks as standard.

4. You’re burning wet, unseasoned, or treated wood. Everett’s mild winters trick people into burning anything, from pallet wood to pressure-treated lumber, until their chimney fills with toxic tar and soot faster than expected.

Everett’s average winter humidity (around 87%) means wood dries slower than in drier climates. Burning wood with over 20% moisture content creates twice the creosote of seasoned wood, and treated lumber releases toxic chemicals that corrode chimney components. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) estimates that improper wood burning causes 25% of all chimney fires, many preventable with the right fuel.

If you’ve been using firewood from a local lot without checking moisture content (use a moisture meter or knock two pieces together, if they thud, they’re dry), your chimney is paying the price. Switch to properly seasoned hardwoods like oak or maple, and store them under a tarp in a dry area. A chimney sweep in Everett will confirm if your recent wood choices have already damaged your flue. For homes near the Snohomish River, where humidity lingers, we often see severe buildup in just a few weeks of burning unseasoned wood. Everett chimney sweep tips include a fuel checklist to avoid this.

5. Animals have taken up residence in your chimney. Everett’s mild winters mean birds, squirrels, and even raccoons nest in chimneys year-round, not just in spring.

Everett’s proximity to forests and wetlands makes our chimneys prime real estate for wildlife. Bird nests cut off airflow, pile up flammable creosote, and turn your chimney into a tinderbox. Signs include feathers, droppings, or the sound of scratching above your fireplace. Never reach in yourself, animals can bite or scratch, and their nests are often built on top of flammable creosote.

DIY removal risks damaging the chimney or leaving debris behind. A licensed chimney sweep in Everett uses specialized tools to safely evict animals and clean the flue thoroughly. For example, last winter, we removed a family of raccoons from a chimney in the Everett West neighborhood, only to find their nest had created a creosote bomb that would’ve ignited with the first fire. After cleaning, we installed a stainless steel chimney cap to keep them out. Everett chimney cap repair is often part of the solution after animal removals.

6. Your chimney is older than 20 years or made of brick/mortar. Everett’s historic homes (like those in the Downtown Everett district) often have chimneys with deteriorated mortar or cracked liners, hidden risks DIY tools can’t fix.

Brick chimneys in Everett’s older neighborhoods can develop hairline cracks over time, especially after our heavy winter rains. These cracks let water seep in, freeze, and expand, weakening the structure. A licensed chimney sweep will spot these during an inspection and recommend repointing (sealing mortar joints) or even a full relining if the damage is severe.

DIY mortar repairs rarely last in Everett’s climate. The moisture from our frequent rain and the salt air near the waterfront accelerate deterioration. If your chimney’s older than two decades, book an inspection before the first cold snap hits. Many Everett homeowners wait until they see water stains on their ceiling, but by then, the damage could require a full chimney rebuild. Everett Level 2 chimney inspection is the gold standard for catching these issues early.
