Golden’s high-elevation climate and historic homes make chimneys prime targets for squirrels, birds, and bats. Never attempt removal yourself, disturbing nests can cause fires, structural damage, or void warranties. Andrew Chen Chimney Inc. uses humane traps, professional-grade tools, and sealed systems to remove animals safely, then inspects for damage before sealing gaps. Always schedule this before fall to avoid winter hazards.
How do you clear out critters stuck in your chimney?
Chimney animal removal is the process of safely extracting live or deceased animals (squirrels, birds, raccoons, bats) from a chimney flue or chase, then repairing any damage they caused. In Golden, this often involves older masonry homes near Clear Creek or the foothills, where wildlife seeks shelter in unused chimneys. Unlike a standard chimney sweep, animal removal requires specialized tools, like one-way exclusion doors, humane traps, and high-pressure air systems, to avoid harming the animal or damaging your flue liner. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) warns that DIY removal can push debris into living spaces or ignite nests, creating fire hazards. Golden’s dry, windy conditions make this risk even higher, as nests dry out and become flammable faster than in humid climates. We cover this in the full list of services.
How Golden’s climate makes animal infestations worse
Golden’s unique mix of high desert and mountain proximity creates ideal conditions for chimney invaders. The dry air and temperature swings from summer to winter force animals to seek insulated spaces, like brick chimneys, during cold snaps. Squirrels, for example, often nest in Golden’s older homes along North Table Mountain or near Clear Creek, where chimneys lack modern seals. Birds like starlings or sparrows build nests in flue caps or loose mortar joints, while bats prefer the drafty chase areas of homes built before the 1980s. The EPA’s Burn Wise program the EPA's Burn Wise program notes that unused chimneys are 3x more likely to attract wildlife than those with annual inspections. If you’ve noticed rustling in your chimney or piles of droppings near the flue cap, schedule removal before fall, animals are most active in September as they prepare for winter.

Step-by-step: How Andrew Chen Chimney Inc. removes animals safely
Our process starts with a visual inspection from the roof to confirm the animal’s location and assess damage. For live animals, we use humane traps or one-way exclusion doors to guide them out without harm. Dead animals require careful extraction with vacuum systems or poles to avoid scattering debris into your home. Every removal includes a full chimney sweep to clear nests, droppings, and insulation materials, critical in Golden, where creosote buildup from past fires can mix with organic debris, creating a fire risk. After removal, we repair any damaged mortar, flue liners, or caps, then install stainless steel mesh or caps to prevent re-entry. Unlike generic crews, we document every step and provide a warranty on our work. For Golden homes with historic masonry, we also check for structural weaknesses caused by animal activity. Contact us for a free estimate, we’ll arrive with the right tools and leave your chimney sealed tighter than before.
Warning signs your Golden chimney has animals (and what they mean)
Don’t wait for a fire or foul odor to act. These Golden-specific signs mean animals are in your chimney: - Rustling or scratching noises during quiet hours: Squirrels or raccoons are common in Golden’s older neighborhoods like North Table Mountain. The noise often sounds like someone shuffling paper. - Piles of droppings near the flue cap or on the roof: Bird nests leave white guano, while squirrels create dark, pellet-like droppings. In Golden’s dry climate, these can bake into the mortar, weakening it. - Strong, musty odors when the fireplace is cold: Animal urine and decomposing nests create a pungent smell that lingers even after sweeping. This is more noticeable in Golden’s high-altitude homes, where air circulation is different. - Soot or debris in your fireplace after lighting a fire: Animals block airflow, causing incomplete combustion and black soot. If you see this, extinguish the fire immediately and call a pro. - Visible nests or chewed insulation in the fireplace: Squirrels often shred attic insulation to line their nests, leaving shredded fiberglass or cellulose in your flue. This is a fire hazard and voids most home warranties.
Why DIY chimney animal removal is dangerous in Golden
Golden homeowners often try DIY removal with traps or smoke, but this backfires. Animals panic and scatter debris into living spaces, or nests ignite during a test fire. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that DIY attempts account for 15% of chimney fires, higher in Colorado due to our dry fuels. Another risk is damaging your flue liner. Many Golden homes have clay or metal liners installed in the 1970s–90s, which can crack under pressure from DIY tools. Our crew uses specialized vacuums and exclusion systems designed for Golden’s chimney styles, ensuring no damage to your system. Plus, improper removal can void manufacturer warranties on stoves, inserts, or even your home insurance. For $200–$500 (depending on the animal and damage), you avoid costly repairs later. See our pricing for transparent estimates.
Golden-specific animal removal costs and what’s included
Pricing varies based on the animal, chimney height, and damage. Here’s what Golden homeowners typically pay: - Squirrels or raccoons: $250–$400. Includes extraction, nest removal, and minor repairs to mortar or caps. - Bird nests (starlings, sparrows): $200–$350. Often requires mesh installation to block re-entry. - Bats or large nests: $400–$600. Bats require extra caution due to health risks (guano contains histoplasmosis spores). - Severe damage (collapsed liners, structural issues): $600–$1,200+. Common in Golden’s older homes near Clear Creek, where moisture and animal activity weaken masonry. Every job includes a free inspection, animal removal, full sweep, and a 1-year warranty on repairs. We also offer discounts for Golden homeowners who bundle animal removal with their annual chimney sweep /services/. Unlike national chains, we don’t upsell unnecessary parts, just honest labor and materials. Ask about our fall prep package if you’re due for an inspection.
Preventing future animal infestations in Golden chimneys
Golden’s wildlife won’t stop seeking shelter, but these steps reduce risks: 1. Install a stainless steel chimney cap with mesh smaller than 1/4 inch. Our crew recommends models like the Chimney Safety Institute’s certified caps for Golden’s windy conditions. 2. Seal gaps in the chase with high-temperature caulk or mortar. Animals enter through cracks in brickwork, common in homes near North Table Mountain with settling foundations. 3. Use your fireplace regularly. Animals avoid occupied spaces. If you don’t use your fireplace, leave the damper open slightly to deter nesting. 4. Schedule annual inspections. The CSIA the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends this to catch early signs of animal activity. In Golden, we often find nests during spring inspections before homeowners notice odors. 5. Trim tree branches near your roof. Squirrels and birds use them as bridges to chimneys. Golden’s pine and aspen trees provide easy access to homes along Lookout Mountain. For homes in Golden Gate Canyon or near Idaho Springs, we also recommend pressure-washing the chase annually to remove built-up guano, which attracts more animals.

Frequently Asked Questions
My chimney smells like urine even after sweeping. Could it be animals?
Yes. In Golden’s dry climate, animal urine crystallizes faster than in humid areas, leaving a sharp ammonia smell that lingers. If you’ve swept recently and the odor persists, animals are likely nesting higher in the flue or chase. Our crew uses UV flashlights to spot urine stains on mortar, common in Golden’s older homes where animals mark territory. Schedule removal before fall, when scents worsen as animals prepare for winter.
I heard scratching in my chimney last night near Clear Creek. How do I confirm it’s not just the wind?
Golden’s wind can mimic animal sounds, but real activity has patterns. If the noise is rhythmic (like shuffling) and happens at dawn/dusk, peak times for squirrels, it’s likely an animal. Also check for fresh droppings on the roof or soot in your fireplace after lighting a small fire. Our crew often finds nests in chimneys along Clear Creek due to the area’s dense tree cover. Never shine a light up the flue at night, it startles animals, causing them to scatter debris into your home.
My neighbor in North Table Mountain had a chimney fire from a squirrel nest. How do I know if mine is at risk?
Golden’s high-altitude homes are at higher risk because creosote buildup dries faster in our thin air, making nests more flammable. Watch for these signs: black, tarry streaks on the flue (creosote mixed with animal debris), a sweet or smoky odor when the fireplace is cold, or soot blowing back into the room when you light a fire. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) states that 25% of chimney fires start with animal nests. If you’ve noticed any of these, schedule a sweep and animal check, don’t wait for a test fire.
Will removing animals from my chimney void my home warranty?
Only if you DIY it. Many Golden home warranties require professional removal to avoid voiding coverage for fire or structural damage. Our reports detail the work and include photos, which we provide to your insurer if needed. We’ve worked with Golden’s historic homes near CoorsTek Parkway where improper removal caused $3,000 in liner repairs. Always ask your warranty provider before attempting removal yourself, even humane traps can damage flue liners if not used correctly.
