A chimney sweep in Peterson SFB is your first step if you spot animal nests, droppings, or blocked flues. Squirrels and birds create fire hazards by packing debris into flues, while their nests trap moisture, leading to creosote buildup and structural damage. Never attempt removal yourself; call a licensed chimney sweep to avoid carbon monoxide exposure or chimney collapse risks. Peterson SFB’s older homes (many built before 1980) are especially vulnerable due to unlined masonry chimneys.
What Are the Most Common Animal Infestations in Peterson SFB Chimneys?
A chimney inspection in Peterson SFB almost always turns up signs of animal activity, especially in homes near open spaces like Peterson Air Force Base or along the foothills near Fountain Creek. The top culprits here are squirrels (drawn to the dry, insulated flue space), swifts and sparrows (which nest in tight chimney openings), and raccoons (which tear apart caps for easy access). Peterson SFB’s climate, hot, dry summers and cold winters, makes chimneys even more appealing. Animals seek shelter, and your flue becomes a perfect nesting site.
How to spot them before they become a hazard: - Squirrels: Gnawed chimney caps, shredded debris at the base, or loud scratching sounds inside the flue (common in older homes near trees). - Birds: Feathers, droppings, or mud nests clogging the flue (especially in homes near open fields or near the base’s overhanging eaves). - Raccoons: Torn chimney caps, scattered nesting material (leaves, twigs), and strong ammonia smells from urine.
The Chimney Safety Institute of America the Chimney Safety Institute of America warns that animal nests can reduce draft by 70%, forcing smoke and carbon monoxide back into your home. In Peterson SFB, where many homes use wood-burning fireplaces for heat, this is a silent killer. If you’ve noticed soot stains on walls near the fireplace or a musty smell when the fire’s off, animals are likely blocking your flue. Contact Griffins Chimney Co for a free inspection, we’ll confirm the blockage and assess fire risks before removal.
Why DIY Removal Is Dangerous in Peterson SFB (And What to Do Instead)
A homeowner in Peterson SFB once tried to poke a squirrel out of their chimney with a broom handle, only to dislodge a nest of twigs and insulation, which then caught fire when they lit the fireplace. Never attempt DIY removal. Here’s why:
1. Carbon monoxide risk: Animals block flues, trapping deadly gases. The EPA the U.S. Environmental Protection Agency reports that improper chimney use causes hundreds of CO poisonings yearly, many from blocked flues. 2. Structural damage: Squirrels chew through mortar joints, and birds pack mud nests that weaken masonry. Peterson SFB’s older brick chimneys (common in neighborhoods near the base) are especially prone to cracks from animal activity. 3. Fire hazards: Dry nesting material + creosote buildup = a tinderbox. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) states that animal nests are a leading cause of chimney fires in rural and suburban areas.
What to do instead: - Call a licensed chimney sweep in Peterson SFB immediately if you see signs of animals. We use rotary brushes and flexible rods to safely dislodge nests without damaging the flue. - Install a stainless-steel chimney cap with 1/4-inch mesh to block animals while allowing smoke to escape. Peterson SFB’s dry winds can scatter lightweight caps, so we recommend weighted or screw-down models for security. - Schedule a Level 2 inspection (which checks for animal damage to the flue lining) if you’ve had repeated infestations. Many Peterson SFB homes built before 1980 lack proper liners, making them prime targets.
Cost note: Animal removal in Peterson SFB typically runs $150–$300, depending on nest size and chimney height. This is far cheaper than repairing animal-damaged masonry or dealing with a chimney fire. See our pricing for Peterson SFB services for transparent estimates.
Step-by-Step: How a Peterson SFB Chimney Sweep Removes Animal Infestations Safely
When you hire a chimney sweep in Peterson SFB for animal removal, here’s the exact process we follow to ensure safety and compliance:
1. Pre-inspection safety check: - We test for carbon monoxide in the home using a high-grade detector. - If CO levels are elevated, we ventilate the area and delay removal until levels drop.
2. Nest removal: - For squirrels, we use a flexible brush system to break up nests without damaging the flue. Larger nests may require a vacuum attachment to contain debris. - For birds, we often find mud nests packed tightly. These must be soaked with water (from the top down) to soften before removal to avoid inhaling dust. - Raccoon debris (like shredded insulation) is removed with specialized tools to prevent tearing the flue liner.
3. Flue cleaning and inspection: - After removal, we sweep the entire flue to clear creosote and debris left by the animals. - We check for gnaw marks, cracked mortar, or weakened masonry, common in Peterson SFB’s older homes. If damage is found, we recommend repairs before you use the fireplace again.
4. Preventative measures: - We install animal-resistant chimney caps (like the Chim-Chimney or HearthMaster models) to deter future infestations. - For homes near trees (common in Peterson SFB’s residential areas), we suggest chimney guards with 1/8-inch mesh to block smaller pests.
Pro tip: If your chimney has a blocked crown (top), we’ll need to remove and replace it, a job that costs $200–$400 in Peterson SFB. This is often necessary after raccoon or squirrel infestations. Learn more about chimney cap installation to protect your investment.
Warning sign to watch for after removal: If your fireplace smokes excessively or back drafts, the flue may still be partially blocked. This requires a second inspection, never ignore it.
Peterson SFB-Specific Warning Signs: When to Call a Chimney Sweep for Animal Infestations
In Peterson SFB, animal infestations often go unnoticed until they become fire hazards or health risks. Here’s what to watch for in your home:
- Smoke backing into the room: If smoke lingers instead of rising, animals (or their nests) are blocking the flue. This is especially common in older Peterson SFB homes with unlined masonry chimneys. - Animal droppings or feathers near the fireplace: Birds like swifts leave white guano that stains brick and mortar. Squirrels scatter shredded insulation or acorn shells. - Unusual smells: A musty, ammonia-like odor (from raccoon urine) or a rotten-egg smell (from bird nests) means animals are present. - New cracks in the chimney: Squirrels chew mortar, and birds pack mud nests that weaken brickwork. Check for hairline cracks near the crown or base. - Animals entering/exiting the chimney: If you see squirrels or birds flying in and out, they’ve already made it a nest. Wait until they’re gone (usually at dusk) before calling a sweep, never disturb them yourself.
Peterson SFB’s unique risk: Many homes here use wood-burning fireplaces for supplemental heat, even in milder months. The EPA’s Burn Wise program the EPA's Burn Wise program recommends never burning with a blocked flue, but homeowners often don’t realize animals are the cause. If you’ve noticed soot buildup on ceiling fans or walls, your chimney is not drawing properly, likely due to a blockage.
What to do next: If you spot any of these signs, stop using the fireplace immediately. Animals can return overnight, and a single nest can double your creosote buildup in weeks. Schedule a chimney sweep in Peterson SFB today, we’ll remove the infestation and inspect for hidden damage.
How to Prevent Animal Infestations in Your Peterson SFB Chimney (Long-Term Solutions)
Peterson SFB’s mix of older homes, wooded lots, and open fields makes animal infestations a recurring issue. Here’s how to prevent them long-term:
1. Install a proper chimney cap: - Stainless steel caps with 1/4-inch mesh block squirrels, birds, and raccoons while allowing smoke to escape. - Weighted caps (like the HearthMaster 1000) stay in place during Peterson SFB’s high winds. - Cost: $150–$300 installed. See our chimney cap installation services.
2. Seal entry points: - Check for gaps in the chimney crown or cracks in the masonry. Use high-temperature sealant to close openings wider than 1/4 inch. - Peterson SFB tip: If your home has a brick chimney with mortar joints wider than 3/8 inch, squirrels can squeeze through. We recommend repointing (replacing damaged mortar) every 5–7 years.
3. Trim nearby trees: - Squirrels and birds are less likely to nest if tree branches don’t overhang your roof. Keep limbs at least 10 feet away from the chimney. - Peterson SFB note: Many homes near the Peterson Air Force Base perimeter have mature trees, schedule trimming before fall, when animals start nesting.
4. Use deterrents: - Motion-activated sprinklers (like the ScareCrow) can deter animals from approaching. - Ultrasonic repellents (placed near the chimney base) work for squirrels but not birds.
5. Schedule regular chimney sweeps: - Twice a year (before fall and spring) is ideal for Peterson SFB homes. Annual inspections catch early signs of animal activity. - Cost: $120–$250 per sweep in Peterson SFB. Compare sweep vs. inspection costs.
Peterson SFB-specific tip: If you’re a rental property owner, Colorado law requires landlords to maintain safe chimneys. Animal infestations can void your homeowners insurance if they lead to a fire. Learn your legal obligations before the next tenant moves in.
What to Do If You Find a Live Animal in Your Chimney (Safety First)
Finding a live squirrel, bird, or raccoon in your chimney is an emergency. Do not attempt to remove it yourself, here’s the exact steps to take:
1. Evacuate the area: - Animals can bite or scratch if startled. Step back 10 feet from the chimney. - Do not throw objects into the chimney, this can injure the animal or damage the flue.
2. Call a professional: - A licensed chimney sweep in Peterson SFB will use humane removal techniques, like: - Live traps (for squirrels/raccoons) placed at the base. - Carbon dioxide gas (for birds) to safely relocate them. - Cost: $200–$400 for live animal removal, depending on species and chimney height.
3. Ventilate the home: - Open windows and turn on fans to reduce carbon monoxide risk while the animal is present.
4. Prevent recurrence: - After removal, we install a mesh chimney cap and inspect for entry points. Peterson SFB’s older homes often need mortar repairs to seal gaps.
Peterson SFB’s unique challenge: Many homes here have masonry chimneys without liners, making it easier for animals to nest. If you’ve had repeated infestations, consider a stainless steel liner ($1,500–$3,000 installed). Learn about chimney liners.
What NOT to do: - Do not use poison or traps, this is illegal in Colorado and can harm pets. - Do not burn the nest, this releases toxic fumes and can cause a chimney fire. - Do not wait, animals can die in the chimney, creating a foul odor and health hazard.

Never enter the attic or crawl space, raccoons can be aggressive. Call a chimney sweep in Peterson SFB to remove them safely. Learn how we handle raccoon infestations.
I heard birds chirping inside my chimney at night, what should I do?
Those are swifts or sparrows, which nest in tight chimney openings. Do not disturb them during nesting season (spring–summer), it’s illegal under the Migratory Bird Treaty Act. Wait until late August to call a chimney sweep in Peterson SFB for removal. In the meantime, cover the chimney with a tarp to deter them. See our bird nest removal process.
My Peterson SFB fireplace smokes when I light it, could animals be blocking it?
Almost certainly. Smoke backing into the room means the flue is partially or fully blocked. Animals (or their nests) reduce draft by 50–70%, forcing smoke indoors. Stop using the fireplace immediately, carbon monoxide risk rises sharply. Schedule an emergency inspection before your next fire.
