Greenwood Village’s chimneys face unique threats from local wildlife and seasonal debris. The most common culprits are raccoons, squirrels, birds, leaves, and pine needles, all of which create fire hazards. Proactive removal before October’s first frost prevents costly repairs and chimney fires. Schedule a sweep now to avoid peak-season delays.
1. What is animal and debris removal in chimneys?
Animal and debris removal in chimneys is the process of clearing out nests, carcasses, twigs, leaves, and other blockages that accumulate in your flue. Greenwood Village’s mix of older homes (many built in the 1960s–80s) and dry, windy plains creates ideal conditions for wildlife to take up residence. A professional chimney sweep uses specialized tools, like brushes, vacuums, and sometimes even a camera, to remove these hazards without damaging your chimney. The Chimney Safety Institute of America (CSIA) recommends this service at least once a year, but Greenwood Village’s high squirrel and bird activity often demands more frequent checks the Chimney Safety Institute of America.
2. Greenwood Village’s top 7 animal and debris culprits (and why they’re dangerous)
Greenwood Village’s climate and housing stock make these the most common offenders: 1. Raccoons: They shred insulation, chew through mortar, and leave behind feces, all of which create fire risks. Their nests block airflow, forcing smoke into your home. 2. Squirrels: They gnaw on wood framing and chimney caps, creating gaps that let in rain and debris. Their nests trap creosote, accelerating buildup. 3. Birds (especially starlings and sparrows): They pack mud and twigs into flues, reducing draft and increasing carbon monoxide risks. A single nest can weigh 20+ pounds, collapsing into your fireplace. 4. Leaves and pine needles: Colorado’s dry autumn winds push debris into unprotected chimneys. A single storm can fill a flue with flammable material. 5. Dead animals: Decomposition leaves a foul odor and attracts pests. Skunks, rats, and even snakes have been found in Greenwood Village chimneys after homeowners ignored lingering smells. 6. Mud daubers (wasps): Their nests block flue tiles and create sharp edges that damage sweep brushes. 7. Acorns and twigs: Fallen from nearby oak trees (common in Greenwood Village’s older neighborhoods), they clog dampers and force smoke into living spaces.
Each of these requires professional removal. DIY attempts often push debris deeper or damage the chimney. For example, a home near Quail Hollow Drive had a raccoon nest that took three hours to remove safely, plus $400 in repair costs for chewed flashing. Schedule a Greenwood Village chimney sweep before these become emergencies.
3. 5 warning signs your Greenwood Village chimney has animal or debris issues (don’t ignore these)
Greenwood Village homeowners often miss early signs because chimneys are out of sight. Watch for: - Unusual odors: A sweet, musty smell (animals) or rotting vegetation (debris) means something’s trapped. Last winter, a home near Village Square reported a ‘wet dog’ odor, it was a dead raccoon decomposing in the flue. - Smoke backing up into the room: Debris or nests block airflow, forcing smoke into your home. This is a serious fire risk and a clear sign your chimney isn’t drawing properly. - Animal droppings in the fireplace: Fresh scat or chewed wood near the damper indicates active wildlife. A Littleton homeowner near Buffalo Creek found squirrel droppings inside their home’s HVAC vents, traced back to a chimney nest. - New holes or damage around the chimney cap: Gnaw marks or torn metal mean animals are accessing your flue. Greenwood Village’s older brick homes often have loose mortar, making them easy targets. - Increased soot or creosote buildup: Animals and debris disrupt combustion, leaving black residue on walls or glass doors. The EPA’s Burn Wise program notes this as a top sign of poor chimney function the EPA's Burn Wise program.
If you notice any of these issues, shut down the fireplace right away and don’t use it again. A temporary cap or screen won’t solve the problem, it’ll just trap smoke or heat. Contact Buffalo Chimney LLC for a same-day inspection if you notice these signs before October 15, when demand spikes.
4. How Greenwood Village’s climate worsens animal and debris problems (and when to act)
Greenwood Village’s dry, windy conditions and sudden temperature swings create perfect conditions for chimney issues: - Dry autumn winds (September–October): Push leaves, pine needles, and acorns into unsealed chimneys. A single storm can fill a flue with flammable material. Last year, a home near Prairie Center Drive had to replace a damper after acorns jammed it shut during a pre-winter windstorm. - Early freezes (October–November): Animals seek shelter in warm chimneys. Raccoons and squirrels are most active in late September, nesting before the first frost. The National Fire Protection Association (NFPA) reports that 86% of chimney fires start from creosote or debris buildup, often triggered by wildlife the National Fire Protection Association (NFPA)|https://www.nfpa.org/)). - Snowmelt (December–March): Melts debris into a sludge that clogs flues. Greenwood Village’s older homes with clay liners are especially vulnerable to water damage from trapped moisture.
Pro tip: Schedule your chimney sweep before October 15 to avoid peak-season delays. Prices rise by 20–30% in November as homeowners rush to prepare for Thanksgiving gatherings. Check our Greenwood Village chimney sweep costs and book early, our crew often fills up by October 1st.
5. Step-by-step: How a Greenwood Village chimney sweep removes animals and debris (what to expect)
A professional sweep follows this process for animal and debris removal: 1. Inspection: The technician uses a chimney camera to assess blockages, damage, or nests. This costs $100–$150 in Greenwood Village but avoids costly surprises. 2. Animal removal: For live animals, they’re humanely trapped or coaxed out (never killed, this can leave carcasses). Dead animals are bagged and disposed of properly (never burned). 3. Debris clearance: Brushes, vacuums, and air tools remove leaves, twigs, and creosote. A typical Greenwood Village chimney yields 5–15 gallons of debris after a dry autumn. 4. Structural check: The sweep looks for chewed mortar, damaged liners, or rusted caps, common in Greenwood Village’s older homes. Repairs may be needed before winter. 5. Final test: A smoke test ensures proper draft. If smoke lingers, the damper or flue may need adjustment.
What you should do: Clear the fireplace area, move furniture away from the chimney, and ensure pets are secured. The process takes 1–3 hours, depending on the blockage. Learn how to prep your home for a smoother service.
6. DIY vs. professional animal and debris removal: When to call a Greenwood Village chimney sweep
Some homeowners attempt DIY removal with gloves and a shop vac, but this often makes problems worse. Here’s when to call a pro: - If you see animal activity: Never reach into a chimney without knowing what’s inside. A dead raccoon or skunk can carry diseases like leptospirosis. - If debris is deeper than 6 inches: A shop vac won’t reach it, and pushing it down can clog the flue further. - If the chimney smells foul: Decomposing animals or mold require professional ventilation and cleaning. - If your home is older than 30 years: Greenwood Village’s brick chimneys often have deteriorated mortar or cracked tiles that DIY tools can damage.
When DIY might work: If your chimney has a simple leaf blockage and you have a long-handled brush, you can try removing surface debris. But never use a leaf blower, it can push debris into the flue or damage the liner. For anything beyond surface cleaning, hire a licensed Greenwood Village chimney sweep. Our team uses industrial vacuums and cameras to ensure 100% clearance, plus we check for hidden damage.
7. How to prevent animal and debris buildup in your Greenwood Village chimney (seasonal checklist)
Greenwood Village’s dry climate means prevention is key. Follow this seasonal checklist: - Spring (March–May): Inspect your chimney cap for gaps or rust. Replace it if animals can squeeze through. A cap with a mesh screen (1/4-inch mesh) deters squirrels and birds. - Summer (June–August): Trim oak and pine trees near your roof to reduce acorn and needle fall. Greenwood Village’s older neighborhoods near Quail Creek Reservoir are prone to this. - Fall (September–October): Schedule your chimney sweep before October 15. Install a temporary chimney balloon (a flexible cover) if you won’t use the fireplace until winter. - Winter (November–March): Use your fireplace regularly to deter animals. Cold snaps drive wildlife indoors, so keep the damper closed when not in use.
Pro tip: If you’re away during peak animal season (September–November), leave a radio playing near the chimney, animals dislike the noise. For extra protection, consider a stainless steel chimney cap with a spark arrestor, which costs $150–$300 but pays for itself in avoided repairs.

Frequently Asked Questions
My Greenwood Village chimney smells like wet dog, what’s causing it and how do I fix it?
That stench almost always means a dead animal rotting in your chimney pipe. Local critters like raccoons and skunks are the usual suspects. Stop using the fireplace immediately and call a pro. Trying to remove it yourself could spread germs or crack the chimney. A certified sweep will pull out the remains, sanitize the flue, and check for cracks or other damage. Starting fees for cleanup and inspection run about $150.
I found squirrel droppings in my fireplace, how did they get there and what should I do?
Squirrels nest in chimneys year-round but become more active in September as they prepare for winter. Their droppings are a fire hazard and carry diseases like hantavirus. Do not attempt to remove them yourself, the nest is likely deeper in the flue. Schedule a Greenwood Village chimney sweep to safely remove the nest, droppings, and any chewed wood. Our crew uses HEPA vacuums to contain dust and debris.
My chimney is clogged with leaves and pine needles, can I just blow them out with a leaf blower?
No, using a leaf blower can push debris deeper into the flue or damage your liner. Greenwood Village’s dry autumn winds often push leaves and needles into chimneys, but they should be removed with a brush and vacuum. If the blockage is more than 6 inches deep, call a professional. A DIY attempt might leave residue that accelerates creosote buildup, increasing fire risks.
I heard animals in my chimney last night, what should I do before morning?
If you hear scratching or scurrying, do not light a fire, it can trap animals inside or force them into your home. Open windows near the chimney to encourage them to leave, then install a temporary chimney cap or screen. In the morning, schedule a Greenwood Village chimney sweep to inspect for damage or nests. Animals often return if their entry point isn’t sealed.
