Smoke coming from your chimney in Englewood almost always means a blockage, cracked liner, or failing masonry, especially in older brick homes. The most common causes are creosote buildup, a damaged flue, or a collapsed crown. If you see smoke when lighting the fire, or it lingers after the fire dies, call a chimney sweep immediately. Ignoring it risks a chimney fire or carbon monoxide poisoning, both are serious threats in our high-altitude climate where drafts behave differently than at sea level.
What does smoke from a chimney actually mean in Englewood?
A chimney isn’t just a pipe, it’s a system of draft, heat, and airflow designed to pull smoke upward. In Englewood, where homes sit at over 5,400 feet elevation, draft issues are more common because the thinner air reduces suction. When smoke spills into your home instead of exiting the flue, it’s a sign one of three things is wrong: 1. Blockage: Creosote (the sticky byproduct of burning wood) or debris clogs the flue, forcing smoke back down. 2. Draft failure: Cracks in the masonry, a missing or damaged chimney cap, or a collapsed crown disrupt airflow. 3. Liner damage: A cracked or collapsed liner (common in older brick chimneys) lets smoke escape through gaps in the brickwork.
If your chimney is older than 30 years, like many in Englewood’s historic neighborhoods near the Englewood Mall area, it’s even more likely to have deteriorated liners or mortar joints that fail under seasonal temperature swings. The key is acting fast: smoke means poor combustion, which also means higher creosote buildup and a ticking time bomb for a chimney fire. The Chimney Safety Institute of America (CSIA) recommends addressing smoke issues within 24 hours to prevent further damage.
A chimney inspection is a visual and physical check of your flue, liner, masonry, and draft system to identify why smoke isn’t venting properly.
Before you call a chimney sweep, you must confirm the root cause. In Englewood, where many homes have unlined brick chimneys (a common feature in pre-1980s construction), inspections reveal hidden problems: - Creosote levels: A sweep will scrape the flue walls to check for Stage 1 (dry, flaky), Stage 2 (tar-like), or Stage 3 (hard, glassy) buildup. Stage 3 creosote buildup is a fire risk and must be cleared right away. - Liner integrity: Older brick chimneys often have missing or cracked liners. If the liner is gone, smoke will seep through the mortar joints, visible as dark streaks on the exterior bricks. - Masonry cracks: Wind and freeze-thaw cycles in Englewood’s winters can crack the crown or mortar. Even a small crack lets smoke escape and invites water damage. - Draft test: A pro will use a smoke puff test to measure how well your chimney pulls air. If the draft is weak, it’s usually due to a blocked flue or external obstructions (like a nearby tree overhang near the roof).
Pro tip for Englewood homeowners: If your chimney is over 20 years old and you’ve never had a formal inspection, schedule one before your first fire of the season. Many chimney fires in our area start because homeowners assume ‘no smoke’ means ‘safe’, until it’s too late. For a detailed breakdown of what an inspection covers, see our guide on Englewood chimney inspections.
Why does my Englewood chimney smoke when I light the fire, but not after?
This is a classic sign of a cold chimney syndrome, where the flue isn’t warm enough to create a strong draft. In Englewood’s climate, where winter temperatures can drop below freezing overnight, cold chimneys are common. Here’s what’s happening: - When you light the fire, the initial heat struggles to rise because the flue is cold. Smoke lingers in the room until the flue warms up. - Once the fire burns hot enough, the draft kicks in and smoke vents normally, but only until the fire cools. - Local fix: Preheat your chimney by burning a small, hot fire (like newspaper) for 10–15 minutes before adding logs. Or, install a chimney balloon (a disposable draft inducer) to warm the flue faster. However, if this doesn’t work after a few tries, you likely have a blockage or liner issue that requires professional cleaning.
Englewood-specific note: Homes near the foothills (like those in the area around the Englewood Lakes neighborhood) often have taller chimneys, which can exacerbate draft problems. If your chimney is over 30 feet tall, it may need a draft inducer fan or a stainless steel liner to improve airflow. Learn more about upgrading your chimney liner for older brick homes.
Smoke coming from the chimney after the fire dies out: What’s wrong?
If smoke appears after the fire has burned out, your chimney has a negative draft, meaning air is being pushed into the house instead of pulled out. This almost always points to: 1. A blocked flue: Creosote or debris is trapping smoke inside the chimney. 2. A damaged chimney cap: Wind blowing into an open or missing cap creates backpressure. 3. A collapsed crown: Cracks or holes in the crown let wind enter the flue from above, reversing the draft. 4. Improper fireplace setup: A closed damper or a fireplace screen blocking airflow can also cause this.
Englewood’s windy winters make this worse: The city’s location near the plains means gusts can easily disrupt drafts, especially if your chimney is tall or has a wide flue. Solution: Start with a chimney cap inspection, many older homes in Englewood lack them or have rusted, ineffective caps. A proper cap (like a stainless steel mesh cap) can cost $150–$400 but prevents 90% of draft-related smoke issues. If the crown is cracked, you’ll need masonry repairs before the next snowfall. See our guide on chimney cap and crown fixes for Englewood’s brick homes.
How to tell if smoke from your chimney is a creosote blockage (and what to do)
Creosote is the #1 cause of smoke issues in Englewood chimneys, especially in older brick homes. Here’s how to spot it: - Visual signs: Look inside the flue with a flashlight (or hire a pro to do it safely). Stage 1 creosote looks like soot; Stage 2 is sticky and tar-like; Stage 3 is hard and glassy (like amber). - Smell test: If you smell a strong, acrid odor when lighting the fire, creosote is burning off. - Smoke behavior: If smoke pours out immediately when you light the fire and doesn’t clear, the flue is likely 70%+ blocked.
What to do next: 1. Stop using the fireplace until a professional cleans it. Burning with a blocked flue creates toxic gases and increases fire risk. 2. Schedule a chimney sweep, creosote removal requires specialized tools (rotary brushes, pneumatic vacuums) to avoid damaging the liner. 3. Upgrade your burning practices: Use only seasoned hardwood (moisture content below 20%) and avoid softwoods like pine, which produce more creosote. The EPA’s Burn Wise program recommends burning only dry, split wood to minimize buildup.
Cost in Englewood: A creosote removal sweep runs $120–$250, depending on chimney height and blockage severity. If your chimney is over 30 feet tall (common in homes near the Englewood High School area), add $50–$100 for equipment access.

Smoke leaking from the chimney bricks: Is your liner failing?
If you see smoke seeping through the mortar joints or dark streaks on the exterior bricks, your chimney liner is likely cracked or missing. This is a silent emergency in older Englewood homes because: - Brick chimneys without liners (common in pre-1970s construction) rely on the mortar to contain heat and gases. When the liner fails, smoke escapes through the brickwork. - Freeze-thaw damage: Englewood’s winters cause mortar to crumble, creating gaps where smoke (and carbon monoxide) can leak into your home. - Hidden risks: A failing liner also lets heat damage the surrounding masonry, leading to cracks that worsen over time.
How to confirm: - Visual check: Look for black streaks on the exterior bricks near the flue. These are smoke deposits where the liner has failed. - Physical test: Gently tap the bricks around the flue with a hammer. A hollow sound means the mortar is crumbling. - Draft test: If smoke leaks out and the fire smolders instead of burning hot, the liner is restricting airflow.
Fix: You’ll need a new stainless steel liner ($1,200–$3,500 installed, depending on chimney height and complexity). In Englewood, homes with tall, multi-story brick chimneys (like those near the Englewood Lakes) often require custom liners to navigate existing masonry. See our guide on chimney liner upgrades for older brick homes for cost and timeline details. Never ignore this, a failed liner is a fire hazard and a health risk.
Smoke from the chimney after rain: Is your crown leaking?
If smoke only appears after rain, your chimney crown is likely cracked or deteriorated. The crown is the concrete or masonry slab at the top of the chimney, and in Englewood’s wet springs and snowy winters, it’s constantly exposed to moisture. Here’s why this matters: - Water damage: A cracked crown lets rainwater seep into the flue, mixing with creosote to form a corrosive sludge that eats away at the liner. - Draft disruption: Water in the flue creates steam, which can temporarily block airflow and cause smoke to back up. - Mortar erosion: Over time, water seeps into the mortar joints, freezing and expanding to crack the bricks.
How to fix it: 1. Inspect the crown: Look for hairline cracks, spalling (flaking) concrete, or missing sections. If the crown is crumbling, it needs replacement. 2. Seal cracks: For minor damage, a chimney waterproofing sealant ($100–$300) can buy time, but a full crown repair is better long-term. 3. Install a chimney cap: A stainless steel cap with a rain shield prevents water entry and improves draft. Learn about crown repairs and caps for Englewood homes. 4. Check for water stains: If you see dark streaks on the ceiling or walls near the fireplace, water is leaking into your home, this requires immediate masonry repairs.
Englewood’s climate note: The city averages 30 inches of rain annually, with snowmelt adding to crown stress. If your chimney is over 25 years old, the crown has likely deteriorated. Act now, waiting until winter can lead to frozen pipes in the flue and costly repairs.

Frequently Asked Questions
My chimney smokes when it’s windy, is that normal in Englewood?
No, it’s not normal. Englewood’s windy conditions can disrupt drafts, but smoke should never pour into your home. If wind causes smoke to back up, your chimney cap is likely missing, damaged, or too small. A properly sized stainless steel cap ($200–$500) will prevent this. If the issue persists, your flue may need a draft inducer or relining to handle the wind patterns near your roof. See our guide on chimney caps for Englewood homes for solutions tailored to our climate.
I see smoke coming from the chimney bricks, could it be a gas leak?
Unlikely, but not impossible. If the smoke is accompanied by a rotten egg smell (sulfur), hissing noises, or a yellow flame in the fireplace, it could indicate a gas leak, but this is rare in chimneys. More likely, you’re seeing smoke leaking through cracked mortar or a failed liner. However, if you suspect a gas issue, evacuate immediately and call 911. For chimney-related smoke, schedule an inspection to check for liner damage or creosote buildup, both are common in older Englewood brick chimneys. Learn how to spot dangerous chimney warning signs before they become emergencies.
My chimney puffed smoke once but now seems fine, do I still need a full inspection?
Yes, absolutely. A single smoke incident means your chimney has an underlying issue, likely creosote buildup, a draft problem, or a small crack. If you ignore it, the problem will worsen, leading to higher repair costs or a chimney fire. In Englewood, where many homes have unlined brick chimneys, even minor issues can escalate quickly due to our dry winters and windy conditions. Schedule a sweep and inspection before your next fire, it’s the only way to confirm the chimney is safe. See our pricing guide for Englewood chimney sweeps to budget for the service.
I live near the foothills, does my tall chimney need special care?
Yes, tall chimneys in Englewood’s foothills area (like those near the Englewood Lakes) require extra attention because: - Stronger winds at higher elevations can disrupt drafts. - Longer flues are harder to clean thoroughly, increasing creosote risk. - Older brick chimneys may have settled or cracked over time, reducing structural integrity. Solution: Have your chimney inspected annually and consider a stainless steel liner to improve airflow. Tall chimneys also benefit from draft inducers or chimney caps with wind guards.
