A spring chimney inspection in Colorado Springs should include checking for cracked brickwork, creosote buildup, and liner damage, especially after winter fires. Schedule a professional sweep and inspection before summer storms to prevent water damage and fire hazards. Older brick homes near Garden of the Gods need extra attention due to seasonal temperature swings.
A chimney inspection is a thorough check of your chimney’s structure, liner, and flue to identify damage, blockages, or safety hazards before use.
After Colorado Springs’ winter fires and freeze-thaw cycles, your chimney’s brickwork and liner take a beating. A professional inspection goes beyond a quick sweep: it examines mortar joints for cracks, checks for water stains inside the flue, and verifies the liner’s integrity. In older neighborhoods like Old Colorado City, where brick chimneys are common, this step is critical, many homes here have original masonry that’s 50+ years old and prone to hidden damage. The Chimney Safety Institute of America recommends an annual inspection, but spring is the best time to catch issues before summer storms worsen them. If you notice rust stains on the fireplace hearth or a musty smell when the chimney is cold, that’s a red flag. Schedule a spring inspection now to avoid costly repairs later.
Why your Colorado Springs chimney needs a spring inspection (even if it worked fine in winter)
Colorado Springs’ winter fires leave behind creosote, a sticky, flammable residue that builds up in the flue. But spring brings its own risks: melting snow can seep into cracked mortar, and summer storms test weak brickwork. If your chimney passed winter without issues, you might still have hidden problems. For example, a chimney in a home near Red Rock Canyon might look fine after a few fires, but the liner could be deteriorating from high heat exposure. Masonry chimneys in older homes often develop hairline cracks that let in moisture, leading to spalling (flaking brick) over time. The National Fire Protection Association (NFPA) notes that 25% of chimney fires start from undetected creosote buildup or blocked flues. A spring inspection catches these before they become fire hazards. See our full inspection process for what we check during your visit.
Step 1: Check for brickwork and mortar damage (Colorado Springs’ freeze-thaw cycle is brutal)
Colorado Springs’ freeze-thaw cycles expand and contract brick and mortar, causing cracks over time. Start by inspecting the chimney’s exterior for: - Crumbling mortar joints (a sign of water intrusion). - Spalling bricks (flaking or peeling surfaces). - Efflorescence (white, powdery deposits, indicating moisture seepage). In older homes, like those in the Broadmoor neighborhood, original brickwork may have been laid with lime mortar, which erodes faster than modern cement. If you see cracks wider than 1/8 inch or mortar pulling away from bricks, water is getting in, and that leads to rusted damper boxes and weakened masonry. The EPA’s Burn Wise program advises that even small cracks can reduce a chimney’s lifespan by 30%. If you’re unsure, a professional can assess whether the damage needs repointing or full masonry repair. Learn about chimney repair signs before calling a sweep.
Step 2: Inspect the chimney liner (the unsung hero of fire safety)
A chimney liner protects your home from heat damage and directs smoke out safely. In Colorado Springs, older homes often have clay tile liners or single-wall metal liners, both degrade over time. Here’s what to watch for: - Rust stains on the liner or damper (sign of moisture damage). - Cracks or gaps in the liner (allowing heat to escape into combustible walls). - A shiny, glass-like coating inside the flue (Stage 2 creosote, which is highly flammable). If your chimney has no liner or a damaged one, it’s a fire risk. The NFPA’s standard 211 states that all chimneys must have a properly installed liner. In older brick homes, liners often fail because they weren’t secured correctly during installation. A professional inspection uses a camera to check the liner’s full length, something you can’t do with a brush sweep alone. See our liner inspection process to ensure yours is safe for summer fires.
Step 3: Clear creosote buildup (Colorado Springs’ dry air makes it worse)
Creosote is a black, tar-like substance that's left behind when you burn wood, and it can accumulate inside your chimney over time. Colorado Springs’ dry air and high-altitude burning conditions accelerate its buildup, turning it into a fire hazard. There are three stages: 1. Stage 1 (sooty): Easier to remove but still flammable. 2. Stage 2 (glazed): Hard, glass-like coating that requires professional tools. 3. Stage 3 (hardened): A brick-like crust that can only be removed with high-pressure water or chemical treatments. If your chimney hasn’t been swept since last fall, it’s likely at Stage 2 or worse. Hardened creosote is responsible for 25% of chimney fires, according to the CSIA. A professional sweep uses rotating brushes and vacuum systems to remove it safely. If you’ve been burning wet or unseasoned wood (common in Colorado Springs’ damp winters), creosote builds up faster. Learn how to burn wood safely to slow buildup between sweeps.
Step 4: Test the chimney’s draw and ventilation (poor draft = dangerous fires)
A chimney’s draw, the upward pull of smoke, depends on temperature, wind, and flue size. In Colorado Springs, high winds or a blocked flue can reverse draw, sending smoke into your home. To test it: - Light a small piece of newspaper near the fireplace opening. If smoke rises straight up, draw is good. If it lingers or flows sideways, there’s a blockage or poor ventilation. - Check for bird nests, debris, or a collapsed liner. - Ensure the damper is fully open when in use. Older brick chimneys often have narrow flues, which restrict airflow. If your home is in a historic district like Manitou Springs, the chimney may have been built to older standards with less clearance. A professional can measure your flue’s size and recommend adjustments if needed. See common chimney ventilation problems and how to fix them.
Step 5: Schedule a professional sweep and inspection (DIY brushes miss critical issues)
While you can sweep your own chimney with a brush, you won’t catch hidden problems like liner cracks or mortar damage. A professional inspection includes: - Video scan of the flue (to check for cracks, blockages, or liner issues). - Exterior masonry assessment (for water damage or structural weaknesses). - Creosote removal (using industrial tools for hardened buildup). - Safety testing (to ensure proper draw and ventilation). In Colorado Springs, where older brick homes dominate, a professional sweep costs between $120 and $250, depending on chimney height and access. This is a small price compared to a chimney fire repair, which can exceed $5,000. Many homeowners in the Black Forest area wait until fall, but spring is ideal, you’ll avoid the rush before winter and catch any winter damage early.

Frequently Asked Questions
My chimney looks fine after winter, but I’m worried about hidden damage. What should I check first?
Start by inspecting the mortar joints for cracks wider than 1/8 inch and look for white powder (efflorescence) on the bricks, both signs of water damage. Then, check the damper for rust or movement, which indicates moisture seepage. If you see soot stains on the fireplace hearth or a lingering smell when the chimney is cold, schedule a professional inspection. Older brick chimneys in Colorado Springs often hide damage until it’s severe, so don’t wait until you see smoke.
Why Your Inactive Chimney Might Still Smell Musty, Even in the Spring on Wood Avenue
A musty smell means moisture is trapped inside the flue, likely from winter snowmelt seeping through cracks or a damaged liner. This encourages mold growth and accelerates creosote buildup. If you ignore it, the bricks can spall (flake) and the liner may rust. A professional inspection with a camera can pinpoint the source, often near the roof or where the chimney meets the house. Learn how to spot water damage early before it worsens.
I’ve heard creosote is dangerous, but how do I know if mine is at a risky stage?
Stage 1 creosote is sooty and can be brushed out, but Stage 2 (glazed) looks like shiny black glass and requires professional tools. Stage 3 is hardened like brick and needs high-pressure water or chemical treatment. If your chimney hasn’t been swept since last fall, it’s likely at Stage 2 or worse, especially if you’ve burned wet wood. Colorado Springs’ dry air makes creosote stickier, so don’t wait until you see it. A professional sweep can assess the stage and remove it safely.
My chimney has no liner, is it safe to use until I can afford repairs?
No, an unlined chimney is a fire hazard. The NFPA requires all chimneys to have a liner to contain heat and direct smoke. Without one, heat can ignite combustible walls, and creosote has nowhere to stick, meaning it builds up faster and becomes more dangerous. In older Colorado Springs homes, many chimneys were built without liners, but modern codes mandate them. If your budget is tight, prioritize a sweep first to remove existing creosote, then plan for a liner installation. See repair vs. replacement costs to budget accordingly.
