We use safe traps and proper ventilation methods. DIY fixes can cause damage, fires, or leave animals trapped. Schedule a free checkup today to handle the problem the right way.

A chimney inspection is a thorough check of your flue, liner, and masonry to spot damage, blockages, or animal nests, something you can’t see from the fireplace alone.

Cornelius’s mild winters and dense wooded areas make it a prime spot for squirrels, birds, and even raccoons to take up residence in chimneys. These animals don’t just leave mess, they chew through flue liners, nest with flammable debris, and block airflow, creating fire hazards. A chimney inspection is your first step: a certified sweep climbs your roof, uses a camera to check the flue, and looks for signs like gnawed mortar or droppings. In Cornelius, where older homes with brick chimneys are common, inspections often reveal nests hidden behind flue tiles or in unused chimneys. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends inspections before every heating season, but if you suspect animals, don’t wait. Contact Pelican Chimney Inc. today for a no-obligation inspection, we’ll tell you exactly what’s inside and how to remove it safely.

Most homeowners in Cornelius mistake animal droppings for soot, but these two look nothing alike. Soot is black and powdery; animal waste is brown, clumpy, and often smells like ammonia.

One of the first signs of a chimney animal infestation in Cornelius homes is finding droppings near your fireplace or on the roof. Unlike soot, which is fine and black, animal waste is chunky, brown, and has a strong ammonia smell, almost like a litter box. Birds leave small, white specks, while squirrels and raccoons produce larger, irregular piles. If you’ve noticed these near your fireplace or on the roof, animals are likely nesting inside. Another clue? A sudden increase in flies or moths around your chimney. These pests thrive in animal waste, so their presence is a red flag. In Cornelius’s humid summers, droppings can also attract mold, which spreads quickly in the damp flue. If you spot any of these signs, avoid touching the waste, it can carry diseases like histoplasmosis. Instead, call a professional to assess the situation. Our crew uses EPA-approved disinfectants to clean up safely after removal.

You might think a chimney cap keeps animals out, but many Cornelius homes have caps with gaps larger than a squirrel’s body. A proper cap should have mesh smaller than 1/4 inch.

Chimney caps are supposed to block animals, but many in Cornelius, especially older homes, have caps with gaps big enough for squirrels to squeeze through. A proper cap should have mesh no larger than 1/4 inch, but DIY or cheap caps often fail this test. If you’ve seen squirrels on your roof or heard them chattering in the flue, your cap might not be doing its job. Even new caps can fail if they’re not installed correctly. For example, caps on flat roofs (common in Cornelius’s suburban neighborhoods) need extra sealing to prevent wind from lifting them. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) notes that improper caps are a leading cause of animal infestations. If you’re unsure about your cap, have it inspected during your next chimney sweep. We offer cap inspections and replacements, including humane animal removal if needed.

Humane removal means trapping animals alive and releasing them, never smashing nests or using poison. Cornelius homeowners should never attempt this themselves.

If you’ve confirmed animals are in your chimney, your first instinct might be to seal the flue or use repellents. But these methods often trap animals inside, leading to starvation or fire hazards from chewed nesting material. The humane approach involves using one-way exclusion devices, traps that let animals out but not back in. Our team at Pelican Chimney Inc. uses these traps, along with proper ventilation techniques, to safely remove squirrels, birds, and raccoons without harming them. For example, in Cornelius’s Birkdale Village area, we’ve removed over 50 squirrels in the past year using this method. After removal, we clean the flue thoroughly and install a mesh cap to prevent future infestations. Never attempt removal yourself, animals can bite, scratch, or carry diseases like rabies. Schedule a humane removal service and let the pros handle it.

The cost to remove animals from your chimney in Cornelius ranges from $150 to $400, depending on the species, nest size, and whether repairs are needed.

Pricing for chimney animal removal in Cornelius depends on several factors. A simple bird nest removal might cost $150–$250, while a squirrel infestation, with chewed flue liners and extensive droppings, can run $300–$400. If the animals damaged your masonry or liner, repairs add $200–$600. For example, a home on Jetton Road recently paid $350 for squirrel removal plus $400 for liner repairs after the animals gnawed through the flue. Insurance may cover part of the cost if the damage was caused by the animals, but check your policy first.

Remember, DIY removal can lead to hidden damage, so investing in professional service now saves money in the long run.

After animals are removed, your chimney needs a deep clean to remove droppings, nesting material, and any lingering odors, something a standard sweep won’t handle.

Once animals are out, your chimney isn’t safe to use until it’s thoroughly cleaned. Animal waste contains ammonia, bacteria, and mold spores that can spread through your home if left behind. A standard sweep won’t cut it, you need a deep clean with disinfectants and high-pressure flue cleaning to remove all traces. In Cornelius’s humid climate, mold grows quickly in damp flues, so we use EPA-approved cleaners to kill spores and prevent regrowth. After cleaning, we also check for structural damage, like chewed mortar or weakened masonry, which needs repair before you light another fire. Our deep-cleaning service includes a post-removal inspection to ensure your chimney is safe. Skipping this step can lead to health issues or even a chimney fire, so don’t cut corners.

The best time to remove animals from your chimney is late spring or early fall, avoid winter, when trapped animals can’t survive outside.

Timing matters when removing animals from your chimney. Late spring (April–May) or early fall (September–October) are ideal because temperatures are mild, and animals can easily be released without harm. Avoid winter, trapped squirrels or birds can’t survive outside in Cornelius’s cold snaps, and they may chew through flue liners in desperation. Summer is also risky because heat can stress animals during removal. If you discover an infestation in winter, contact us immediately, we’ll use emergency exclusion methods to keep animals safe while we plan a full removal in spring. Book your service early to avoid last-minute rush fees, especially before the holidays when demand spikes.

Frequently Asked Questions

Why do squirrels keep coming back into my Cornelius chimney even after I’ve had it cleaned?

Squirrels return if your chimney cap has gaps larger than 1/4 inch or if the cap isn’t properly sealed. Cornelius’s wooded areas provide easy access for squirrels to jump from trees to roofs. After removal, we install mesh caps with no gaps and seal them tightly. Ask about our cap upgrades to prevent future visits.

I heard birds in my chimney last night, how do I know if they’re still there or just flying through?

If you hear birds chirping or scratching during the day, they’re likely nesting. Nighttime sounds could be bats or birds passing through, but if you see feathers or droppings near the fireplace, they’re inside. Birds often nest in unused chimneys, especially in Cornelius’s older homes. Schedule an inspection, we’ll use a camera to confirm and remove them safely.

Can I use my fireplace after animals are removed but before the chimney is fully cleaned?

No, never use your fireplace until the chimney is professionally cleaned and inspected. Animal waste contains flammable nesting material and harmful bacteria. Even a small amount left behind can cause a chimney fire or spread mold. Our team cleans and inspects before giving you the all-clear to light up again.

What’s the fastest way to tell if my Cornelius chimney has animals without calling a pro?

Look for droppings near the fireplace or on the roof, listen for scratching or chirping inside the flue, and check for feathers or nests in the firebox. If you see any of these, animals are likely inside. Don’t wait, animals worsen over time for a safe removal.
