If you see smoke pouring into your home when lighting a fire, hear loud cracking or popping from the chimney, or notice white powdery residue near the fireplace, your chimney needs an emergency inspection. Greenwood Village’s dry fall winds and older homes make these risks worse, delaying inspection can lead to chimney fires or carbon monoxide poisoning. Call a licensed chimney sweep immediately if you spot any of these signs.
1. Smoke Backdrafting Into Your Home (The Most Dangerous Sign)
A chimney inspection is a thorough check of your flue, liner, and damper to spot blockages, cracks, or structural damage. Greenwood Village’s older homes, especially those near the foothills, often have chimneys built with single-wall masonry that’s prone to creosote buildup and deterioration. When smoke billows back into your living space instead of venting outside, it’s a clear sign your chimney is blocked or damaged. This isn’t just annoying; it’s a fire hazard and a carbon monoxide risk. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) warns that backdrafting is the #1 reason for chimney fires in residential homes. If this happens, stop using the fireplace immediately and call a Greenwood Village chimney sweep services/ before attempting to burn another fire. We cover this in what we do page.
2. Loud Cracking or Popping Sounds (Your Chimney Is Under Stress)
Hear a sharp crack or pop when lighting a fire? That’s not normal. In Greenwood Village’s dry climate, the rapid temperature shifts between summer heat and winter cold cause masonry to expand and contract. Over time, this weakens mortar joints and brickwork. If you hear these sounds, your chimney may have hairline cracks or a failing liner. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) notes that cracked flues are a leading cause of chimney fires, especially when combined with creosote buildup. Don’t ignore it, schedule an emergency inspection. A Greenwood Village chimney sweep areas/greenwood-village/ can assess whether you need a repair or a full relining before winter sets in.

3. White or Black Powder Near the Fireplace (Creosote Buildup Is Accelerating)
Creosote is the sticky, black residue left when wood doesn’t burn fully, it’s flammable and dangerous. But in Greenwood Village, where homes often use dry pine or oak firewood, creosote dries out faster and becomes more flammable. If you see white powder (like talcum powder) or black soot near the fireplace, your chimney has Stage 2 or Stage 3 creosote, both highly combustible. Stage 3 creosote looks like thick, shiny black paint and can catch fire from even a small spark. The EPA’s Burn Wise program the EPA's Burn Wise program advises that homes in high-elevation areas like Greenwood Village should have their chimneys swept more frequently if they burn wood often. If you spot these signs, don’t wait for your annual sweep, book an emergency chimney sweep contact/ to avoid a chimney fire. More on this in our background and licensing page.
4. Rust on the Damper or Chimney Cap (Moisture Is Damaging Your Flue)
Greenwood Village’s humidity spikes in late summer and early fall, and if your chimney isn’t properly sealed, moisture seeps in. Rust on the damper or chimney cap means water is corroding metal components, which weakens the flue’s structure. Over time, this can lead to leaks, blockages, or even a collapsed chimney crown. The CSIA recommends checking for rust annually, especially in homes near Greenwood Village’s wetter microclimates, like those closer to Cherry Creek. If you notice rust, it’s a sign your chimney needs an inspection, and likely repairs, to prevent long-term damage. A Greenwood Village chimney sweep areas/cherry-hills-village/ can assess whether you need a new damper, cap, or crown repair before winter makes access difficult. Full details in our full service area page.
5. Animals Nesting in Your Chimney (A Hidden Fire and Health Hazard)
Birds, squirrels, and even raccoons are drawn to Greenwood Village chimneys, especially in older homes with loose mortar or missing caps. If you see feathers, nests, or animal droppings near your fireplace, critters have taken up residence. This is more than a nuisance, animal nests block airflow, trap creosote, and create fire hazards. Worse, droppings can release harmful bacteria like histoplasmosis. The CSIA reports that animal-related chimney fires account for 20% of all residential chimney fires. If you suspect animals are in your chimney, don’t try to remove them yourself. Call a Greenwood Village chimney sweep areas/littleton/ for a safe, humane inspection and cleanup. We’ll ensure your flue is clear and secure before you light another fire.

Frequently Asked Questions
Gas-like smells when lighting a fire? What that odor means and whether your Greenwood Village chimney is safe
No, that’s not normal. A gas-like smell (often rotten eggs or sulfur) means carbon monoxide or gas is leaking into your home. This could be from a cracked flue, improper venting, or a failing appliance. Greenwood Village’s older homes with unlined chimneys are especially prone to this. Turn off the fireplace immediately, open windows, and call a chimney sweep contact/ for an emergency inspection. Never ignore this, carbon monoxide poisoning is deadly.
I noticed cracks in the mortar around my chimney, how urgent is this?
Very urgent. Cracked mortar in Greenwood Village’s freeze-thaw cycles (common in fall and winter) allows water to seep in, weakening the masonry. Small cracks can turn into structural failures, especially if your chimney is over 30 years old. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) recommends repairing mortar cracks immediately to prevent chimney fires. Schedule an inspection with a Greenwood Village chimney sweep areas/englewood/ before the first frost, delaying could lead to a collapsed chimney crown.
My chimney hasn’t been swept in 2 years, should I panic?
Not yet, but act fast. The CSIA the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends annual sweeps for wood-burning fireplaces, but Greenwood Village’s dry climate can accelerate creosote buildup. If you’ve burned wood regularly, you likely have Stage 1 creosote (dust-like), but it could progress quickly. Book an inspection contact/ and a sweep before winter. If you’ve never had a sweep, expect higher creosote levels, this isn’t a DIY job. A professional chimney sweep areas/highlands-ranch/ will assess the risk and clean safely.
Can I still use my fireplace if I see soot on the ceiling or walls?
No, stop using it immediately. Soot on ceilings or walls means your chimney is leaking smoke into your home, which indicates a blockage or draft issue. Greenwood Village’s high winds can worsen this problem, especially in homes with single-wall chimneys. Soot also signals incomplete combustion, increasing carbon monoxide risk. Turn off the fireplace, open windows, and call a Greenwood Village chimney sweep contact/ for an emergency inspection. Never use the fireplace again until it’s cleared.
