Animals in your Bordentown chimney aren’t just a nuisance—they’re a serious threat to your historic masonry and indoor air quality. From raccoons nesting in your flue to squirrels chewing through your liner, prompt removal and prevention are critical. Learn how to identify signs, safely evict intruders, and secure your chimney with proven methods tailored for older homes in Bordentown.
What a chimney inspection reveals about animal intruders in Bordentown’s older homes
A chimney inspection is the only way to confirm whether animals have entered your flue or damaged your masonry. In Bordentown, where many homes date to the 1800s, brickwork often has cracks or missing mortar joints that invite wildlife. A Level 1 inspection described in detail here includes a visual check of the flue and chimney crown, where raccoons and squirrels frequently gain entry. If you’ve noticed rustling sounds, a musty odor, or debris falling into the fireplace, an inspection will reveal claw marks, nesting material, or even droppings clogging the flue. Older masonry chimneys in Bordentown are especially vulnerable because their liners may be cracked or improperly sized, creating easy access points for animals. Skipping this step risks hidden damage that worsens over time, especially during our damp New Jersey winters when moisture accelerates brick deterioration. Don’t wait until you see an animal darting out of your chimney on a cold morning—schedule an inspection before fire season arrives.
How to safely evict animals from your Bordentown chimney without harming them or your home
Evicting animals from your chimney requires patience and the right approach. First, confirm the type of animal by listening for noises at dusk or dawn when they’re most active. Raccoons are common in Bordentown’s older neighborhoods like the Historic District, while squirrels prefer chimneys with uncapped flues. Never use smoke, fire, or chemicals—these methods endanger both the animal and your home. Instead, install a one-way exclusion device (like a chimney cap with a wildlife guard) at the top of the flue to allow animals to leave but not re-enter. This is safest when done by a professional who can also inspect your liner for damage. If the animal is a mother with young, wait until the babies are old enough to leave on their own—typically 4–6 weeks—to avoid trapping them inside. Once the animals are gone, clean out nesting material and sanitize the flue to remove odors that might attract others. For persistent problems, consider a full chimney cap installation we offer here to prevent future intrusions.
Why Bordentown’s older chimneys are magnets for wildlife—and what to do about it
Bordentown’s historic homes were built with brick and mortar that’s now decades past its prime, making chimneys prime real estate for animals. Cracked flue liners, missing chimney caps, and deteriorating crowns create entry points that raccoons, squirrels, and even birds exploit. In neighborhoods like Broad Street or the Delaware & Raritan Canal corridor, older masonry often lacks modern safeguards, leaving flues exposed to the elements and wildlife. Moisture from New Jersey’s humid summers and freeze-thaw cycles in winter accelerates brick spalling, widening gaps that animals can squeeze through. If your chimney hasn’t been inspected in years, it’s likely harboring hidden damage—and possibly guests. Addressing this starts with a thorough inspection to assess liner condition and masonry integrity. If repairs are needed, tuckpointing or liner replacement may be necessary to restore a secure barrier against intruders. Don’t let a small crack turn into a major repair bill—or worse, a fire hazard.

The cost of ignoring animals in your chimney: Damage you’ll face in Bordentown homes
Ignoring animals in your chimney isn’t just messy—it’s expensive. Raccoons and squirrels can chew through chimney liners, exposing your home to carbon monoxide risks and reducing heating efficiency. Nesting materials block airflow, forcing smoke back into your living room and coating walls with soot. In Bordentown’s older homes, moisture from animal urine accelerates brick spalling, leading to costly tuckpointing or even chimney rebuilds. A single raccoon family can leave behind enough debris to clog your flue entirely, requiring a full cleaning and inspection before you can safely use your fireplace again. The longer you wait, the higher the repair costs climb. For example, repairing a cracked liner in a historic Bordentown chimney can cost between $1,200 and $3,500, while tuckpointing damaged brickwork ranges from $1,500 to $4,000. These aren’t DIY fixes—older masonry requires specialized tools and materials to match the original craftsmanship. Addressing the problem early with professional removal and repairs saves thousands in the long run.
Step-by-step: How to permanently block animals from your Bordentown chimney
Permanently blocking animals starts with a chimney cap—your first line of defense. A high-quality stainless steel cap with a mesh screen (1/4-inch openings) keeps out raccoons, squirrels, birds, and even leaves while allowing smoke to escape. For Bordentown’s historic homes, choose a cap designed to match your chimney’s style, whether it’s a custom copper cap for a Victorian home or a standard black cap for a mid-century build. Next, inspect your chimney crown for cracks and repair them with a waterproof sealant to prevent moisture damage that widens gaps. If your liner is cracked or missing, consider a stainless steel liner installation we specialize in to create a smooth, unbroken barrier. Finally, schedule annual inspections to catch new cracks or cap damage before animals find another entry point. In Bordentown, where humidity and temperature swings stress masonry, proactive maintenance is key. A well-sealed chimney not only keeps wildlife out but also improves draft and reduces creosote buildup—a win for safety and your wallet.
When to call a professional: 3 signs your Bordentown chimney needs expert help
Some chimney problems are too risky for DIY fixes. If you’ve tried DIY exclusion methods and still hear noises, it’s time to call a professional. Another red flag is visible damage to your liner or crown—cracks wider than a credit card or crumbling mortar joints that animals can exploit. If you’ve noticed a sudden drop in heating efficiency or smoke backing up into your home, a blocked flue could be the culprit. Older Bordentown homes with historic brickwork often have liners that are decades old; these may need replacement to restore a secure barrier. A certified chimney sweep can perform a Level 2 inspection with a camera to assess hidden damage and recommend repairs like tuckpointing or liner installation. Don’t gamble with your safety—professional help ensures the job is done right the first time, with warranties and insurance coverage for peace of mind.
Bordentown homeowners’ guide: Seasonal timing for animal-proofing your chimney
Timing matters when it comes to animal-proofing your chimney. In Bordentown, late summer and early fall are critical windows—animals start seeking shelter for winter, and they’ll exploit any weak spot in your chimney. Scheduling a chimney sweep and inspection before fire season in October ensures your flue is clear and capped before the first cold snap. Spring is another ideal time to check for damage after winter’s freeze-thaw cycles, which can widen cracks in older masonry. Avoid waiting until you hear scratching noises—by then, animals may have already nested and caused damage. If you’re in a historic neighborhood like the Bordentown City Historic District, consider scheduling a pre-winter inspection in September to address any masonry or liner issues before they become urgent. Proactive maintenance aligns with Bordentown’s climate and keeps your chimney—and home—safe year-round.

Frequently Asked Questions
Should I try to remove animals from my Bordentown chimney myself or call a professional?
Call a professional. DIY removal risks harming the animal and your chimney. A certified sweep can safely evict wildlife, clean the flue, and install exclusion devices without damaging historic masonry.

It depends on the liner’s condition. Minor cracks may be repairable, but older liners in Bordentown homes often need replacement for safety and efficiency. A Level 2 inspection will determine the best solution.
Do raccoons in my chimney mean I’ll need a full chimney rebuild in Bordentown?
Not necessarily. Raccoons cause damage by chewing liners and nesting, but a professional can repair or replace the liner and tuckpoint damaged brickwork. Full rebuilds are rare unless the masonry is severely deteriorated.
How often should I inspect my Bordentown chimney for animal intrusions?
Annually. Bordentown’s climate and older homes make yearly inspections essential. If you’ve had past animal issues, consider bi-annual checks in spring and fall to catch new entry points early.
