If you hear scratching or see debris in your chimney, animals are likely nesting there. Our Arden Hills chimney sweep team uses specialized tools and safety protocols to remove them without damaging your chimney or exposing you to carbon monoxide. Never attempt this yourself, animals block airflow, trap creosote, and create fire hazards. Schedule a sweep before winter to ensure your chimney is safe for burning.
1. A chimney inspection is a thorough visual and camera-based check of your chimney’s interior, including the flue, liner, and smoke chamber, to identify animal nests, blockages, or structural damage before cleaning begins.
When animals take up residence in your chimney, they don’t just leave behind mess, they create a tinderbox. Squirrels, birds, and bats build nests with twigs, leaves, and even insulation, which traps creosote (a highly flammable tar) inside your flue. In Arden Hills, where winter fires spike after heavy snowfall, this combination is a recipe for disaster. Our first step is always a level 2 chimney inspection using a high-definition camera to pinpoint exactly where the animals are nesting, how deep the blockage is, and whether their presence has damaged your liner or flue. For example, we recently found a family of squirrels in a Shoreview home’s chimney that had chewed through the liner, exposing the masonry to moisture and weakening the structure. Without this inspection, the homeowner wouldn’t have known the chimney was at risk of collapse during a fire. Arden Hills chimney sweep
2. Why animals in your chimney are a carbon monoxide risk, and how our Arden Hills team fixes it immediately
Animals don’t just block airflow; they disrupt the entire combustion process. A blocked chimney forces smoke and toxic gases, including carbon monoxide (CO), back into your home instead of venting outside. In Arden Hills, where older homes with brick fireplaces are common, this is especially dangerous because many homeowners don’t realize their detectors won’t catch CO from a blocked chimney until it’s too late. Our team starts by sealing off the fireplace with a temporary airtight barrier to prevent CO from entering the living space while we work. We then use rotating brushes and flexible rods to break up nests without damaging the chimney walls. For instance, a Vadnais Heights homeowner called us after their CO detector went off during a cold snap; we found a bird’s nest packed with insulation that had completely sealed the flue. After removal and a thorough sweep, their fireplace passed a safety test with zero CO leakage. Chimney sweep near me
3. The 3-step process to safely remove animal nests without damaging your chimney
Removing animal nests isn’t as simple as pulling them out, it requires precision to avoid collapsing the chimney or leaving debris behind. Here’s how we do it in Arden Hills: 1. Disrupt the nest: We use a vacuum attachment to suck out loose debris while the animal is still inside (usually at dawn or dusk when they’re least active). This prevents them from scattering and nesting elsewhere in your attic or walls. 2. Extract the animal: For live animals, we use humane traps or one-way exits (like a funnel device) to guide them out safely. In Minnesota, it’s illegal to harm wildlife, so we follow Minnesota DNR guidelines Minnesota DNR for relocation. 3. Clean and seal: After removal, we sweep the chimney with stiff brushes and high-pressure air to eliminate all traces of nesting material. If the animal caused damage (like chewed liners), we repair it on the spot to meet NFPA 211 standards the National Fire Protection Association (NFPA)|https://www.nfpa.org/)). For example, a Circle Pines homeowner had a raccoon family living in their chimney for months. We removed them, cleaned the flue, and installed a chimney cap with a mesh screen to prevent future intrusions. Without this, the homeowner would’ve faced a costly repair when the raccoons damaged the flue further. Chimney sweep cost Arden Hills
4. How to tell if animals are in your chimney, and what to do before winter
Don’t ignore warning signs until a blaze or carbon monoxide alarm forces your hand. Here are the 5 signs animals have infested your Arden Hills chimney: - Scratching or scurrying noises coming from the chimney, especially at night. - Debris (twigs, leaves, feathers, or droppings) around the fireplace or on the roof. - Strong, musty odors when you light a fire, this means animal waste is burning. - Smoke backing up into your home instead of venting outside. - Soot stains on the ceiling or walls near the fireplace, caused by poor draft. If you spot any of these red flags, shut down your fireplace right away, no exceptions. Animals can trigger a chimney fire in as little as 15 minutes of burning with a blocked flue. Our Arden Hills team recommends scheduling a pre-winter inspection by October to avoid last-minute emergencies. Best time for chimney sweep Arden Hills
5. The #1 mistake Arden Hills homeowners make when they find animals in their chimney
Many homeowners try to solve the problem themselves, by blowing debris out with a shop vac, pouring chemicals down the flue, or even lighting a fire to “scare them out.” All of these methods fail and create bigger risks. Blowing debris can push it deeper into the chimney, where it ignites. Chemicals can corrode your liner and create toxic fumes. And burning a fire with a blocked chimney fills your home with CO. In one case, a Blaine homeowner tried using a leaf blower to clear a bird’s nest and ended up with $8,000 in chimney repairs after the force of the air collapsed part of the flue. Our Arden Hills team uses industrial-grade tools designed for this exact scenario, including flexible rods to break up nests and HEPA-filtered vacuums to contain dust and dander. We also check for hidden damage, like chewed liners or cracked masonry, that DIY methods miss. DIY chimney mistakes
6. How much does it cost to remove animals from a chimney in Arden Hills?
Costs vary based on the type of animal, nest size, and damage, but here’s what Arden Hills homeowners typically pay for animal removal and chimney cleaning: | Service | Average Cost Range | What’s Included | |---------------------------|-----------------------|---------------------------------------------| | Basic animal removal | $150–$300 | Nest extraction, vacuum cleanup, basic sweep | | Moderate infestation | $350–$600 | Animal removal, liner inspection, partial reline if needed | | Severe damage (chewed liner, collapsed flue) | $800–$1,500+ | Full inspection, repairs, and relining | | Emergency after-hours call | $400–$750 | Immediate CO risk assessment + removal | For example, a squirrel nest in a Lino Lakes home ran about $220 to remove, while a bird’s nest with insulation in a North Oaks chimney required a $950 repair after the bird chewed through the liner. If you suspect an infestation, call us before winter, early removal is always cheaper than emergency repairs. Chimney sweep pricing
7. How to prevent animals from returning to your Arden Hills chimney
Once animals are out, you’ll want to keep them from coming back. Here’s what our team recommends for Arden Hills homes: - Install a chimney cap with a mesh screen (1/4-inch or smaller) to block squirrels and birds while allowing smoke to escape. We use stainless steel caps that withstand Minnesota winters. - Seal gaps around the chimney base with high-temperature caulk to deter entry. - Trim tree branches near your roof to remove nesting spots for birds and squirrels. - Schedule annual inspections, even if you don’t burn your fireplace, animals may still nest there. The Chimney Safety Institute of America (CSIA) recommends inspections at least once a year the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)). For instance, a Shoreview homeowner had squirrels return twice before installing a cap with a baffle system. Now, their chimney stays clear year-round. If you’re unsure about the best cap for your chimney, our team can recommend code-compliant models that meet Arden Hills’ building standards. Chimney permits Arden Hills

Frequently Asked Questions
My chimney smells like ammonia after I light a fire, could it be animals?
Yes, that’s a strong sign of animal waste burning. Ammonia smells come from urine and droppings left behind by squirrels, birds, or bats. If you notice this in your Arden Hills home, stop using the fireplace immediately and call a chimney sweep. Burning animal waste releases toxic fumes, including ammonia and carbon monoxide. Our team uses air quality monitors during cleaning to ensure your home stays safe. Chimney sweep Arden Hills
Why does my Arden Hills chimney make a whistling noise when I burn wood?
A whistling or hissing sound usually means air is leaking into your flue, often caused by cracks or a blocked section from animal nests. In Arden Hills, older brick chimneys are prone to this after squirrels chew through mortar. If you hear this, don’t ignore it, it can reduce draft power and increase creosote buildup. Our inspection includes smoke puff tests to locate leaks and seal them properly. Chimney inspection Arden Hills
Can I use my fireplace after a chimney sweep removes animals?
Only if our team gives you the all-clear after a full inspection. Even after animal removal, we check for creosote buildup, structural damage, and proper draft. In Arden Hills, we often recommend a test burn to confirm the chimney vents correctly. If any issues are found, we’ll repair them before you light another fire. Never assume it’s safe, carbon monoxide poisoning from a poorly vented chimney is preventable. Chimney safety tips Arden Hills
