A chimney draft problem in Colorado Springs usually means your fireplace isn’t pulling smoke upward like it should. For older brick homes, this often stems from cracked mortar, a collapsed crown, or a liner that’s too large for the flue. The fix depends on the root cause: sealing masonry gaps, repairing the crown, or installing a properly sized liner. Left unchecked, poor draft forces toxic gases into your home and increases fire risk, especially during Colorado’s high-elevation winter burns. A professional inspection and sweep are the first steps to diagnosing the issue.
What happens when your Colorado Springs chimney loses its pull?
A chimney draft problem means your fireplace isn’t drawing smoke and gases upward through the flue as designed. In Colorado Springs, where older brick homes dominate neighborhoods like Old Colorado City and the North End, draft issues are common due to aging masonry and high-elevation atmospheric pressure. When draft fails, smoke spills into your living space, carbon monoxide builds up, and creosote, highly flammable tar, accumulates faster on chimney walls. The Chimney Safety Institute of America (CSIA) notes that draft problems are the #1 cause of chimney fires in older homes, often linked to blocked flues, cracked liners, or deteriorated mortar joints. If your fire smokes heavily or smells like gas when lit, that’s your chimney telling you it’s time for a pro check.
Why do older Colorado Springs brick chimneys lose draft?
Brick chimneys in Colorado Springs built before the 1980s often lack modern insulation or properly sized liners, making them prone to draft loss. Here’s what typically goes wrong in these homes: - Cracked or missing mortar: Over time, freeze-thaw cycles in Colorado’s dry winters (with sudden temperature swings) erode mortar between bricks. Even small gaps disrupt airflow. - Collapsed or damaged crown: The concrete or brick cap at the top of your chimney can crack or shift, letting rainwater seep into the flue. Water turns to steam during burns, blocking the chimney’s ability to draw air. - Improper liner sizing: Many older chimneys have oversized liners (installed to meet outdated codes), which create turbulence instead of smooth draft. A liner that’s too large forces smoke to cool and settle before exiting. - Obstructed flue: Debris like bird nests, fallen leaves, or creosote buildup (especially in unlined brick flues) narrows the passage, restricting airflow. In Colorado Springs, chimney swifts and starlings often nest in unused chimneys, creating blockages. - Downsized or missing damper: Older homes frequently have dampers that don’t seal tightly or are left partially open, letting cold air enter the flue and canceling out the draft.
The key fix? Start with a Level 2 chimney inspection (which includes a video scan of the flue) to pinpoint the exact issue. For brick chimneys, masonry repairs often resolve draft problems before needing a liner replacement. Learn more about chimney inspections and what they reveal.
How to test your chimney draft at home (before calling a pro)
Before scheduling a chimney sweep in Colorado Springs, try this simple draft test: 1. Hold a sheet of newspaper near the firebox, if it doesn’t catch immediately, your draft is weak. If the flame tilts toward the fireplace, your chimney has positive draft (good). If it tilts away, you’ve got a negative draft (smoke will spill into your home). 2. For a more precise test, use a draft gauge (available at hardware stores for ~$20) or a smoke puff test: Light a match, blow it out, and hold the smoke near the fireplace opening. Watch the smoke’s direction, it should rise straight up. If it spreads sideways or sinks, your draft is weak. 3. Check for backdrafting: Light a fire and listen for a whooshing sound. If smoke rushes back into the room, your damper may be stuck or the flue is blocked.
If your draft fails these tests, don’t ignore it. Colorado Springs’s dry air and high altitude make poor drafts especially dangerous. A blocked or damaged chimney can force carbon monoxide into your home, invisible, odorless, and deadly. The U.S. Environmental Protection Agency the EPA’s Burn Wise program warns that improper chimney function is a leading cause of CO poisoning during winter. If you suspect a draft issue, contact a licensed chimney sweep immediately. See our service areas if you’re outside Colorado Springs, we cover Manitou Springs, Woodland Park, and Castle Rock.
Step-by-step solutions for fixing draft problems in Colorado Springs
The repair path depends on the diagnosis. Here’s how Orca Chimney Inc tackles draft issues in older brick homes: 1. Cleaning and clearing obstructions: A thorough sweep removes creosote, soot, and debris. In Colorado Springs, we often find nests from chimney swifts or fallen pine needles from nearby forests clogging flues. A clean flue restores draft in many cases. 2. Masonry repairs: Cracked mortar or a damaged crown disrupt airflow. We tuckpoint (repoint) mortar joints and re-seal the crown with waterproof mortar. For severe damage, we may recommend a chimney crown repair to prevent water intrusion, which worsens draft problems over time. 3. Damper adjustments or replacement: If your damper is warped or doesn’t seal, we replace it with a top-sealing damper (which improves draft control). Older cast-iron dampers often rust shut, we’ve seen this in homes near Garden of the Gods where moisture seeps through cracked masonry. 4. Liner sizing and installation: If your liner is too large (a common issue in pre-1990s homes), we install a properly sized stainless steel liner to match the flue’s dimensions. For example, a 10-inch flue should have a 10-inch liner, not the 12-inch liner some contractors install to ‘future-proof’ it. The wrong size creates turbulence and kills draft. 5. Chimney cap installation: A stainless steel chimney cap with a mesh screen prevents debris and animals from blocking the flue. In Colorado Springs, we recommend caps with spark arrestors to meet local fire codes, especially for homes near Pikes Peak where embers can ignite dry brush.
Cost note: Minor draft fixes (cleaning + damper repair) typically run $150–$300. Masonry repairs or liner installations start around $800–$2,500, depending on chimney height and damage. Always get a written estimate, some ‘chimney sweeps’ in Colorado Springs quote high for unnecessary liner replacements when a simple crown repair would fix the issue. Compare repair vs. replacement costs for your chimney.
When to replace vs. repair a chimney for draft issues
Not all draft problems require a full chimney rebuild. Here’s how to decide: - Repair if: The masonry is structurally sound but has cracks, the liner is intact but oversized, or the damper is faulty. For example, a chimney in a 1920s bungalow in Fountain might only need repointing and a new damper. - Replace if: The flue is severely corroded, the chimney leans (common in older homes on sloped lots near Cheyenne Mountain), or the brickwork is crumbling. A leaning chimney can’t maintain proper draft no matter how much you clean it.
Pro tip: If your chimney is over 50 years old and made of unlined brick, it may need a chimney liner installation to meet modern safety codes. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) requires lined chimneys for wood-burning fireplaces, and many Colorado Springs insurance companies now mandate it. A lined chimney improves draft and extends the life of your brickwork by protecting it from creosote and moisture.
Local example: In the historic Broadmoor neighborhood, we’ve seen chimneys from the 1930s where the original brick flue is still usable, but the homeowner added a stainless steel liner to comply with insurance requirements. The draft improved, and the chimney now lasts decades longer. See our guide on chimney liner installation for older homes.
Preventing draft problems in Colorado Springs’ high-elevation climate
Colorado Springs’s thin air and temperature swings make chimney maintenance critical. Here’s how to keep your draft strong: - Burn only seasoned hardwood: Green or resinous wood (like pine) creates more creosote, clogging the flue faster. The EPA the EPA’s Burn Wise program recommends burning wood with 20% moisture or less. Locally, buy from suppliers like Colorado Springs Firewood who dry wood in our low-humidity climate. - Use the right fire size: Overloading your fireplace cools the flue, killing draft. Aim for a hot, small fire, not a roaring blaze. In Colorado Springs, we often see homeowners burn too much wood to ‘heat the room,’ which actually makes the chimney work harder and reduces efficiency. - Inspect before every fire season: Schedule a chimney sweep and inspection in late summer or early fall, before you light your first fire. The CSIA recommends this timing to catch draft issues before winter, when blocked chimneys become deadly. - Install a heat-resistant chimney cap: A cap with a spark arrestor prevents debris and animals from blocking the flue. In areas like Black Forest, where wildfire risk is high, a cap also reduces ember escape. - Test the damper: Make sure it moves freely when opened or closed. If it’s stuck, lubricate it with a silicone spray (avoid WD-40, it leaves a residue that burns). For older homes, consider upgrading to a top-sealing damper for better airflow control.
Seasonal note: Colorado Springs’s fall weather (cool nights, warm days) creates ideal conditions for moisture buildup in chimneys. If you notice white smoke when lighting a fire, that’s steam from water in the flue, another sign of poor draft. Learn how to prep your chimney for Colorado Springs’s fall weather.
Why DIY fixes for draft problems fail in Colorado Springs
Many homeowners try to fix draft issues themselves, only to make them worse. Here’s why DIY often backfires in Colorado Springs: - Improper cleaning: Scrubbing creosote with a wire brush can damage brick flues or dislodge mortar. Creosote in older chimneys is often Stage 3 (glazed), which requires professional removal to avoid flue fires. - Wrong liner sizing: Installing a liner that’s too small or too large disrupts draft. For example, a 12-inch liner in a 10-inch flue creates turbulence, while an 8-inch liner in a 10-inch flue leaves gaps where smoke escapes. - Masonry mistakes: Repointing mortar incorrectly (using the wrong mortar mix or not sealing against moisture) leads to faster deterioration. Colorado Springs’s freeze-thaw cycles test even ‘permanent’ repairs. - Ignoring structural issues: A leaning chimney or cracked crown can’t be ‘fixed’ with a sweep or new damper. These require professional masonry work to restore draft safely.
Local warning: We’ve seen DIY ‘chimney sweeps’ in Colorado Springs use shop vacs or leaf blowers to clear flues, this pushes soot deeper into the chimney and can damage liners. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) prohibits this method, yet some unlicensed crews still use it. Always hire a CSIA-certified chimney sweep like Orca Chimney Inc to avoid costly mistakes. See why licensing matters in Colorado Springs.

Frequently Asked Questions
How much does it cost to fix a draft problem in a Colorado Springs brick chimney?
Costs vary based on the fix. A chimney sweep and inspection runs $120–$250. If the issue is cracked mortar or a damaged crown, repairs start around $500–$1,200. Replacing a chimney liner (needed for older unlined brick flues) costs $1,500–$3,500, depending on height and liner type. For example, a 10-foot chimney in Manitou Springs with a stainless steel liner averages $2,200–$2,800. Always get a written estimate, some ‘chimney sweeps’ upsell unnecessary liner replacements when a simple crown repair would work. See our pricing guide for Colorado Springs.
Can I still use my fireplace if the draft is weak but not dangerous?
No, even a mild draft problem is unsafe. Weak draft means smoke and carbon monoxide will enter your home, and creosote buildup accelerates, increasing fire risk. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) states that any chimney with poor draft should not be used until repaired. In Colorado Springs, where wood-burning fireplaces are a winter staple, ignoring draft issues can lead to carbon monoxide poisoning or a chimney fire, both are preventable with a professional inspection. If your draft is weak, stop using the fireplace and call a chimney sweep immediately.
How often should I check my chimney draft in Colorado Springs’s dry climate?
Check your draft twice a year: once in late summer/early fall (before fire season) and again after winter’s last use. Colorado Springs’s dry air and high elevation make draft problems more likely than in humid climates. The CSIA the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends annual inspections for homes that burn wood regularly. If you notice smoke spilling into the room, soot on walls, or a strong odor, test the draft immediately, these are red flags. Learn the best times to schedule a chimney sweep in Colorado Springs.
Will a new chimney cap fix my draft problems in an older Colorado Springs home?
Not always. A chimney cap prevents debris and animals from blocking the flue, but it won’t fix structural issues like cracked mortar, a damaged crown, or an oversized liner. However, a properly installed cap (with a spark arrestor) can improve draft by reducing turbulence at the top of the chimney. In Colorado Springs, we often pair a new cap with masonry repairs or liner adjustments for the best results. If your draft is still weak after adding a cap, schedule a Level 2 inspection to check for hidden problems like a collapsed flue or rusted damper. See how chimney caps work in Colorado Springs’s climate.
