How to Prevent Animal Nesting in Chimneys in Brooklyn

                                             

If you've ever detected rustling, chirping, or scratching noises emanating from your chimney, then you're not alone. Brooklyn residents must contend with the ongoing and sometimes dangerous issue of animals nesting in their chimneys. Animals such as raccoons, squirrels, birds, and bats find their way in, particularly during colder weather. Sadly, their presence results in clogged flues, bad odors, health issues, and greater fire hazards.

 At Brooklyn Chimney Sweep, we specialize in safe, effective chimney animal removal and chimney protection strategies to help keep your home safe year-round.

Why Do Chimneys Attract Wildlife in Brooklyn?

In an urban setting like Brooklyn, wild animals often have difficulty finding undisturbed, warm nesting areas. Chimneys fit the bill to a tee-making them the number one target. Here's why your chimney might be drawing in unwanted visitors:

Warm Shelter: Chimneys hold heat, which is why they are appealing to animals during cold months.

Privacy: The quiet, dark interior provides a safe location for animals to nest.

Easy Access: Caps-less or broken coverings on chimneys are open invitations.

While these animals are merely seeking shelter, their presence can be intrusive and hazardous to homeowners.

Common Chimney Invaders & Their Risks

Following is a brief rundown of the most frequent Brooklyn chimney-dwelling animals, and issues they create:

Animal	Risk	Most Active
Birds	Can block airflow and result in fatal carbon monoxide	Spring
Squirrels	Gnaw on wood and wiring, deposit droppings	Fall / Winter
Raccoons	Strong and aggressive; knock off chimney caps and flues	Year-Round
Bats	Carry rabies and histoplasmosis viruses	Summer / Fall

How to Know if Animals Are in Your Chimney

Not every infestation is visually apparent. Look for these telltale signs:

Scratching, squeaking, or fluttering noises

Strong, objectionable odors

Debris or nesting material in the fireplace

Smoke entering your home

Sightings of animals at the chimney opening

If you notice any of these warning signs, it's time to act.

Preventative Measures to Keep Wildlife Out

Keeping animals out is easier—and less expensive—than it is to deal with the consequences. Here's how you can seal up your chimney:

1. Install a Quality Chimney Cap

This is your first line of defense. A chimney cap allows smoke to escape while keeping animals out.

Choose stainless steel or copper for durability

Look for caps with mesh sides to block even small intruders

2. Book Regular Chimney Inspections

Have a certified technician examine your chimney once a year. They’ll check for:

Signs of animal activity

Structural damage

Loose or missing caps or screens

Early detection can prevent expensive repairs and infestations.

3. Seal Entry Points

Damaged brickwork or openings close to flashing can offer entry. Seal the openings with fire-safe sealants or get a repair professional.

4. Prune Tree Branches

Branches along your roofline can serve as bridges for raccoons and squirrels. Trim them away at least 10 feet from your chimney.

5. Utilize Natural & Electronic Repellents

As an additional protective measure:

Mount motion-sensitive lights close to the chimney

Use natural repellents such as peppermint oil

Opt for ultrasonic animal repellents

When to Hire a Chimney Professional

In case you realize that animals are already occupying space, do not attempt to address it yourself. DIY removal could be dangerous and against local regulations regarding wildlife. 

A chimney professional can: 

Remove animals and nests humanely and safely

Clean, disinfect and deodorize the chimney 

Repair chewing damage and scratching damages 

Suggest and install preventive measures permanently
