If you spot animal nests in your Littleton chimney, call a professional chimney sweep immediately. DIY removal risks damaging brickwork, disturbing wildlife, or triggering a chimney fire. A licensed sweep uses humane methods, inspects for structural damage, and seals entry points, often in under two hours for simple nests. Never attempt removal yourself if you suspect bats, raccoons, or birds.
What is chimney animal removal, and why Littleton homes need it
A chimney animal removal is the process of safely extracting nests, debris, and wildlife from your flue or chimney structure without harming the animals or damaging your masonry. Littleton’s older brick homes, especially those built before the 1980s, are particularly vulnerable. The city’s mix of mature trees, open spaces near foothills, and historic neighborhoods creates ideal nesting conditions for birds, squirrels, raccoons, and even bats. Unlike newer homes with sealed chimneys, older Littleton properties often have cracked crowns, loose bricks, or missing caps, inviting unwelcome guests. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) warns that nests block airflow, trap creosote, and create fire hazards, yet many homeowners delay removal until smoke backs into their homes. If you’ve noticed soot stains on walls near your fireplace or heard scratching in the flue, your chimney may already be compromised. Read up on the full list of services.
Step 1: Identify the animal, and what it means for your chimney
Not all critters require the same removal approach. In Littleton, the most common offenders are: - Birds (swallows, sparrows): Light nests of twigs and feathers, often found in the flue liner or crown. These can be removed with minimal masonry damage but may indicate a cracked crown needing repair. - Squirrels: Heavy nests of leaves, shredded paper, and insulation. Squirrels chew through mortar and brick, weakening your chimney’s structure. Their nests often leave tooth marks on the liner. - Raccoons: Messy, foul-smelling nests with food scraps. They tear through liners and crowns, creating large entry points that require professional sealing. - Bats: Rare but dangerous. Bat guano is highly corrosive to brick and mortar, and disturbing their nests violates federal law USA.gov. Only licensed wildlife removal teams should handle bat infestations.
Local tip: If you’re near South Platte Park or the foothills, bird nests are more likely. Homes on older streets like Washington or Main often deal with squirrels due to mature trees. Always confirm the animal before attempting removal, mistaking a bat nest for a bird’s could lead to fines or legal trouble.
Step 2: Why DIY removal is riskier than you think (and what to do instead)
Littleton’s brick chimneys aren’t built like modern steel flues, they’re porous, prone to erosion, and often have hidden cracks. Here’s what happens when homeowners try DIY removal: - Damaged liners: Scraping or pulling nests can tear stainless steel or clay liners, exposing your home to carbon monoxide. Older homes with single-wall liners are especially vulnerable. - Masonry collapse: Bricks weakened by animal urine or guano may crumble when disturbed. A single loose brick can cost $200–$500 to replace, plus the risk of a falling hazard. - Legal consequences: Disturbing bat nests or protected bird species (like swallows) can result in fines from the U.S. Fish and Wildlife Service. Littleton’s historic districts add another layer, unauthorized repairs can void insurance. - Fire hazards: Nests trap creosote, turning your chimney into a tinderbox. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that animal nests cause 10% of chimney fires, often because homeowners ignore them until it’s too late.
What to do instead: Schedule a chimney sweep with a team that offers humane removal. We use specialized tools to extract nests without damaging liners or brickwork, then inspect for structural issues. For bats, we coordinate with licensed wildlife experts to ensure compliance with local and federal laws. Contact us for a free estimate, we’ll assess your chimney’s condition and recommend repairs if needed.
Step 3: Humane removal methods we use in Littleton (and how they protect your home)
Our process prioritizes animal safety, masonry integrity, and long-term prevention. Here’s how we handle nests in Littleton’s older homes: 1. Visual inspection: We use a chimney camera to identify the animal, nest location, and any damage to the liner or brick. This avoids unnecessary tearing or scraping. 2. Gentle extraction: For birds and squirrels, we use vacuum systems or hand tools to remove nests in one piece, minimizing debris that could clog the flue. Bats require a sealed containment unit to prevent escape. 3. Liner and crown check: After removal, we inspect the liner for tears and the crown for cracks. If we find damage, we recommend repairs before sealing entry points. 4. Humane deterrents: We install chimney caps with fine mesh (¼-inch or smaller) to block animals while allowing smoke to escape. For persistent squirrels, we add stainless steel baffles inside the flue. 5. Post-removal sweep: Even after nest removal, creosote buildup from trapped smoke can remain. We always perform a thorough chimney sweep to ensure your flue is safe for burning.
Cost note: Humane removal in Littleton typically ranges from $150–$350, depending on the animal, nest size, and whether repairs are needed. This is far cheaper than repairing a damaged liner or rebuilding a collapsed crown. See our pricing guide for older brick homes to understand what’s included.
Step 4: Preventing future nests in Littleton’s climate and housing
Littleton’s dry summers and cold winters create the perfect conditions for animal nests. Here’s how to keep your chimney clear year-round: - Install a chimney cap with mesh: A cap with ¼-inch or smaller mesh blocks birds and squirrels while allowing smoke to vent. For homes near South Platte Park, we recommend heavy-duty caps with a rain shield to prevent water damage. - Seal cracks in the crown and masonry: Use chimney sealant on mortar joints and small cracks. For larger gaps, repointing (replacing damaged mortar) is often needed. Learn how to spot water damage in your crown. - Trim nearby trees: Overhanging branches near your roof provide easy access for squirrels and birds. Keep limbs at least 10 feet away from your chimney. - Use a chimney balloon: For homes with open flues (common in older Littleton properties), a chimney balloon (a flexible liner) creates a barrier that animals can’t penetrate. This is especially useful if your liner is damaged. - Schedule annual inspections: The EPA’s Burn Wise program the EPA's Burn Wise program recommends inspecting your chimney before and after fire season. In Littleton, that means checking in late spring (before nesting season) and fall (before winter burning).
Local pro tip: If your home is in a historic district or near open space (like the foothills), animals may return annually. We’ve seen cases where homeowners skip prevention and end up with nests every spring. A $200 chimney cap now can save you $1,000+ in repairs later.
Step 5: What to do if you find a nest, and when to call us immediately
Not all nests require urgent action, but some signs demand professional help right away. Here’s how to assess the situation: - Call us immediately if: - You see bats flying in and out of your chimney (federal law protects them). - You smell a strong ammonia or rotten odor (sign of bat guano or raccoon waste). - You notice soot stains on walls or ceilings near the fireplace (blocked flue = fire risk). - You hear scratching or scurrying during the day (animals are active and may be chewing your liner). - Wait to call if: - The nest is small (a few twigs) and you haven’t used the fireplace in months. - You’ve already installed a chimney cap and want to monitor for a few days.
Littleton-specific warning: If your home is near Cherry Creek or the foothills, bird nests are more likely to contain parasitic mites (like those from European starlings). These mites can infest your home if nests are disturbed improperly. Always err on the side of caution, humane removal is safer than DIY.
Next steps: If you’re unsure, schedule a free inspection. We’ll confirm the animal, assess damage, and provide a clear plan, no pressure, no upselling. Many Littleton homeowners assume a nest is harmless until smoke starts backing into their living room. Don’t wait until it’s an emergency.

Frequently Asked Questions
My chimney has a bird’s nest, but I haven’t used the fireplace in years. Do I still need a chimney sweep?
Yes. Even unused chimneys need inspection after animal nests because birds and squirrels leave creosote residue, guano, and debris that can corrode your liner or brick. In Littleton’s dry climate, this buildup dries into a flammable tar. We’ve seen nests in disused chimneys cause fires when homeowners later try to light a fire. Always schedule a sweep and inspection after removal, it’s the only way to confirm your flue is safe.
I think a raccoon got into my chimney. How do I know if it damaged the liner or masonry?
Raccoons have a habit of shredding cast-iron liners and brickwork mortar in older homes. Watch for: - Scratch marks along the liner’s seams (their teeth leave telltale grooves). - Shifting or crumbling bricks near the chimney’s top (mortar pulled loose by their digging). - A sharp, chemical-like stench (their droppings reek of ammonia and spoiled meat). If you notice any of these in your 1920s Craftsman or Victorian row home, call a pro immediately, raccoons will keep coming back, and their nests can weigh over 50 pounds, risking a partial collapse. We start with chimney inspections using high-def cameras to spot hidden damage before we remove them.
My neighbor said I can just pour water down the chimney to remove a nest. Is that safe?
No, this is a dangerous myth, especially in Littleton’s older brick homes. Pouring water can: - Weaken mortar by accelerating erosion in already cracked crowns. - Damage liners if the water pressure dislodges debris that scrapes the walls. - Fail to remove the nest completely, leaving behind flammable material. The proper method is humane extraction with a vacuum or hand tools, followed by a full inspection. We’ve seen water ‘solutions’ lead to $800+ in liner repairs when homeowners tried to DIY.
I found a dead bird in my chimney. Should I remove it myself or call a chimney sweep?
Remove it only if it’s fully decomposed and not blocking the flue. If the bird is fresh or the nest is intact, call us immediately. Dead animals in chimneys: - Attract scavengers (like raccoons or rats) that can cause worse damage. - Release parasites (e.g., mites from starlings) that may infest your home. - Hide structural damage (e.g., a cracked liner or loose bricks). In Littleton, we’ve had cases where homeowners removed a dead bird, only to find a live nest behind it. Always let us inspect first, it’s safer and often cheaper in the long run.
