Animals That Nest in Sacramento Chimneys
Sacramento's warm climate, abundant trees, and mix of urban and suburban neighborhoods make it home to a variety of wildlife that commonly use chimneys as shelter and nesting sites.
Safe, humane removal of birds, squirrels, raccoons, and bats from Sacramento chimneys. We seal entry points and install caps to permanently prevent re-entry.
Sacramento's warm climate, abundant trees, and mix of urban and suburban neighborhoods make it home to a variety of wildlife that commonly use chimneys as shelter and nesting sites.
A protected migratory bird that nests in chimneys April–October. Their chittering sound is distinctive. Active nests cannot legally be removed, but we install caps post-season to prevent next year's nesting.
The most common large animal in Sacramento chimneys. Female raccoons enter chimneys in spring to birth and raise kits. Raccoon exclusion requires careful timing to avoid trapping young animals.
Tree squirrels in Sacramento commonly fall into chimneys or intentionally nest in them. They're destructive — squirrels chew damper components and leave nesting material that creates fire hazards.
An invasive species that aggressively nests in chimneys. Unlike chimney swifts, starlings are not protected and their nests can be removed. Starling nests create significant blockages and fire hazards.
Several bat species roost in Sacramento chimneys, especially in older masonry. Bats are protected under California law. We provide legal exclusion that allows bats to exit but not re-enter, and install permanent caps.
House sparrows, pigeons, and other birds commonly nest in Sacramento chimneys. Bird nests block airflow, harbor parasites, and create fire hazards when dry nesting material ignites.
Common chimney animals in Sacramento: chimney swifts (protected birds, April–October), European starlings, raccoons (common in spring with kits), squirrels, bats (protected under California law), and house sparrows. Raccoons are the most frequently reported chimney animal in Sacramento neighborhoods.
Signs of a chimney animal: scratching, chirping, or chattering sounds; animal droppings in the firebox; strong organic odors from the fireplace; debris falling into the firebox; visible bird or animal activity around the chimney top. Call us at +1 916 694 1518 if you notice any of these signs.
Never. Lighting a fire to remove animals is dangerous and inhumane — it can kill the animal inside the flue (creating a blockage and lasting odor), panic a live animal that then enters your home through the damper, or ignite nesting material. Call AL Chimney Service Sacramento for safe, humane removal.
Yes. Chimney swifts are protected under the federal Migratory Bird Treaty Act, making it illegal to remove or disturb active nests from April through October. After swifts depart (typically by October), we can legally install a chimney cap to prevent the following year's nesting.
The most effective permanent solution is a stainless steel chimney cap with 5/8" mesh — small enough to exclude all common Sacramento chimney animals while allowing normal draft. We install caps immediately after removing animals (or after the nesting season for protected species).
