7 Signs Your Tacoma Chimney Has Animal Nests: And How to Remove Them Safely Without Overpaying

By Luis G. Chimney Co. Team · Updated October 24, 2026

If you spot droppings, nests, or unusual smells near your chimney, animals are likely inside. Never attempt removal yourself, it’s dangerous and can damage your chimney. A professional Tacoma chimney sweep will safely remove nests, inspect for structural damage, and provide a clear estimate upfront. Always ask for a free inspection before booking service to avoid hidden costs.

A chimney inspection is a thorough visual and physical check of your chimney’s structure, liner, and flue to identify damage, blockages, or safety hazards, including animal nests. In Tacoma, where moisture and wildlife are common, inspections should happen at least once a year, especially before winter.

Tacoma’s climate, wet winters, mild springs, and dense forests, makes chimneys prime real estate for bats, birds, and squirrels. These animals don’t just leave nests; they chew through mortar, block flues, and create fire hazards. A proper inspection by a licensed Tacoma chimney sweep will spot nests early, before they cause thousands in repairs. For example, a family in University Place University Place, WA discovered a bat colony after their fireplace stopped drawing properly. The nest had clogged the flue entirely, requiring a full reline job at $2,500, costs that could’ve been avoided with a $150 inspection.

Here’s what inspectors look for during a Tacoma chimney inspection: - Mortar damage: Animals chew through bricks and mortar, weakening the chimney’s structure. Look for crumbling joints or missing bricks near the crown or flue. - Blockages: Nests or debris can reduce airflow, causing smoke to back up into your home. A blocked chimney is a fire risk and violates NFPA 211 standards. - Creosote buildup: Animal nests trap soot and moisture, accelerating creosote formation. Thick creosote is highly flammable and can ignite with just a spark. - Unusual smells: A musty or ammonia-like odor near your chimney often means animal activity. Bats and birds leave strong odors that linger even after they’re gone.

Pro Tip: If you’ve noticed any of these signs, schedule an inspection before booking a sweep. Some companies in Tacoma upsell unnecessary services, ask for a detailed report upfront. At Luis G. Chimney Co., we provide free estimates and itemized pricing so you know exactly what you’re paying for /pricing/. For homes in older neighborhoods like Old Town Tacoma or South Tacoma, where chimneys are often built with softer mortar, inspections are especially critical.

5 Questions to Ask a Tacoma Chimney Sweep Before They Start Work on Your Animal-Nest Problem

Not all chimney sweeps handle animal nests the same way. Some will charge extra for ‘emergency’ removals, while others bundle it into a standard sweep. Here are the questions Tacoma homeowners should ask to avoid surprises:

1. ‘Do you have experience removing nests from Tacoma chimneys?’ Some crews specialize in wildlife removal, while others lack the tools or training. Ask for references or photos of past jobs. For example, a crew in Lakewood Lakewood, WA once told a homeowner they’d handle a raccoon nest, only to damage the flue and require a $1,200 repair. Stick with a crew that uses brushes designed for delicate liners and has experience with local wildlife like bats (common in Tacoma’s older homes) or squirrels (a problem in neighborhoods near Point Defiance Park).

2. ‘Will you inspect for structural damage after removing the nest?’ Animals weaken chimneys by chewing mortar and nesting in flue gaps. A sweep should check for cracks, loose bricks, or water damage that could lead to leaks. If they skip this step, you might end up paying for repairs later. At Luis G. Chimney Co., we always include a post-removal inspection in our standard pricing /services/.

3. ‘Do you use a camera inspection to check the flue?’ A flexible camera lets the technician see inside the flue without tearing apart your chimney. This is especially important if the nest is deep or if you suspect damage. Some cheaper crews in Tacoma skip this step to save time, but it’s worth the extra $50–$100 to avoid missing hidden issues.

4. ‘What’s your pricing structure for animal nest removal?’ Avoid crews that quote a flat rate without seeing the problem first. A bat nest in a small flue might cost $150–$250 to remove, while a squirrel nest with extensive damage could run $400–$800. Ask for an itemized estimate, including labor, disposal fees, and any repairs needed. We’ve seen homeowners in Federal Way Federal Way, WA pay $1,000+ because they hired a crew that didn’t disclose the full scope of work upfront.

5. ‘Do you offer a warranty or guarantee on your work?’ Reputable Tacoma chimney sweeps stand by their work. Look for a warranty on repairs (like relining or tuckpointing) and a guarantee that the chimney will pass a post-service inspection. At Luis G. Chimney Co., we offer a 30-day warranty on all repairs and a satisfaction guarantee /about/.

Local Note: Tacoma’s older homes, especially those built before the 1980s, often have single-wall chimneys that are more vulnerable to animal damage. If your home was built in the mid-20th century, prioritize a crew with experience in these types of chimneys.

How to Tell If Your Tacoma Chimney Has an Animal Nest (7 Clear Signs)

Animals don’t announce their presence with a sign on your door. Here’s how to spot nests before they become a fire hazard or require expensive repairs:

1. You see feathers, fur, or droppings near the chimney cap or flue. Birds leave feathers and small droppings, while bats and squirrels scatter fur and larger pellets. Check the roof, chimney crown, and fireplace hearth. A family in Orting Orting, WA noticed white droppings on their porch after their fireplace stopped working, turns out, a family of starlings had nested in the flue.

2. Your fireplace or stove smokes excessively when lit. A nest blocks airflow, causing smoke to back up into your home. If you’ve tried adjusting the damper and the problem persists, animals are likely blocking the flue. The Chimney Safety Institute of America (CSIA) recommends testing for blockages if smoke lingers for more than a few minutes after lighting a fire.

3. You hear scratching, scurrying, or chirping inside the chimney. Bats, birds, and squirrels make noise, especially at dawn or dusk. If you hear rustling when the fireplace is cold, animals are likely nesting inside. In Puyallup Puyallup, WA, a homeowner reported hearing ‘like a family of mice’ in their chimney, it was actually a pair of raccoons.

4. Your chimney smells musty, like ammonia, or has a strong odor. Animal nests emit a pungent smell from droppings and decaying nesting material. If your chimney smells bad even when cold, it’s a red flag. Some homeowners in Sumner Sumner, WA describe the odor as ‘like a farm animal pen’, a sure sign of a serious infestation.

5. You find chewed mortar, bricks, or soot stains around the chimney. Squirrels and bats chew through mortar to expand their nests. Look for small holes in the brickwork or missing mortar joints. If you see fresh damage, animals have been active recently. The city of Tacoma Tacoma, WA notes that older homes in the Hilltop neighborhood often suffer from this due to softer mortar.

6. Your energy bills spike without explanation. A blocked chimney forces your heating system to work harder, increasing energy use. If your furnace or fireplace seems less efficient, check for a nest. The U.S. Environmental Protection Agency estimates that a blocked chimney can reduce heating efficiency by up to 30%.

7. You see animals flying in or out of the chimney. If you spot bats, birds, or squirrels entering or exiting the flue, they’ve already made it a home. Never try to remove them yourself, disturbing a nest can cause animals to fly into your home or damage the chimney further. Call a professional immediately.

What to Do If You Spot These Signs: - Don’t light the fireplace, this can trap animals inside or cause a chimney fire. - Cover the chimney temporarily with a metal cap or tarp to prevent more animals from entering. - Call a licensed Tacoma chimney sweep for a safe removal. DIY attempts often make the problem worse. For example, a homeowner in Bonney Lake Bonney Lake, WA tried using a vacuum to remove a nest and ended up tearing the flue liner, requiring a $1,500 reline.

The Step-by-Step Process for Safe Animal Nest Removal in Tacoma Chimneys

Removing an animal nest isn’t as simple as pulling out a bird’s nest with a broom. Here’s what a professional Tacoma chimney sweep does to handle it safely, and what you should expect when you book service:

1. Inspection with a camera (if needed). The technician uses a flexible camera to assess the nest’s size, location, and any damage to the flue or liner. This step is critical for determining the best removal method. For example, a bat nest in a clay liner requires a different approach than a squirrel nest in a metal chimney.

2. Safe removal of the nest. - Small nests (birds, bats): Crews use specialized brushes or vacuum systems designed for chimneys to avoid damaging the liner. - Large nests (squirrels, raccoons): Technicians may need to dismantle part of the chimney to access deep nests safely. This is why experience matters. Tacoma’s older homes often have fragile masonry. - Live animals: If animals are present, the crew will use humane methods to encourage them to leave before removal. Disturbing a nest can cause animals to fly into your home or damage the chimney further.

3. Cleaning the flue and chimney. After removal, the flue is thoroughly cleaned to remove soot, debris, and any remaining nesting material. This step is often overlooked by cheaper crews, but it’s essential to prevent future blockages. The EPA’s Burn Wise program recommends cleaning the entire chimney system, not just the flue, to ensure safe operation.

4. Inspection for damage. The technician checks for: - Chewed mortar or bricks (common with squirrels and bats). - Cracks or gaps in the flue or liner. - Water damage from nests trapping moisture. If damage is found, the crew will provide a clear estimate for repairs before proceeding. Some companies in Tacoma upsell repairs, always ask for a second opinion if the quote seems high.

5. Sealing the chimney to prevent future nests. - Installing a chimney cap: A stainless steel cap (costing $150–$400) deters birds and small animals. - Sealing gaps: Crews can apply mortar or use mesh to block entry points for squirrels and bats. - Adding a spark arrestor: This prevents embers from escaping while also blocking small animals.

What You Should Pay for Animal Nest Removal in Tacoma: | Service | Typical Cost Range | What’s Included | |---------------------------|-----------------------|---------------------------------------------| | Small nest removal | $150–$300 | Labor, disposal, basic cleaning | | Large nest removal | $400–$800 | Labor, disposal, flue cleaning, damage check | | Nest removal + repairs | $800–$2,000+ | Includes relining, tuckpointing, or cap installation | | Emergency after-hours | $500–$1,200 | Higher due to urgency (e.g., fire risk) |

Pro Tip: If you’re in a neighborhood with known wildlife issues, like near Point Defiance Park or the Tacoma Narrows, ask about preventative measures like chimney caps or mesh screens. These can add $200–$500 upfront but save you thousands in future repairs /blog/tacoma-chimney-prep-guide/.

How to Prevent Animal Nests in Your Tacoma Chimney (Without Overpaying for Repairs)

The best way to avoid costly animal nest removals is to make your chimney less appealing to wildlife. Here’s how Tacoma homeowners can deter animals without breaking the bank:

1. Install a chimney cap. A stainless steel cap (costing $150–$400) blocks birds, bats, and squirrels while allowing smoke to escape. Look for caps with a mesh design, these are more effective at keeping animals out. In Gig Harbor Gig Harbor, WA, homeowners report seeing fewer birds after installing caps with 1/4-inch mesh. Avoid cheap caps with large gaps, squirrels can squeeze through openings as small as 2 inches.

2. Seal gaps and cracks in the chimney. Animals exploit even small openings. Check for: - Missing or damaged mortar between bricks. - Gaps around the chimney crown (the top of the chimney). - Cracks in the flue or liner. Use a high-quality mortar mix to seal gaps, or hire a mason for tough spots. This is a DIY-friendly task for minor repairs, but leave major structural work to a pro. The city of Tacoma Tacoma, WA recommends inspecting chimneys annually for these issues, especially after storms.

3. Keep the area around your chimney clean. Animals are drawn to debris, leaves, and nesting material. Trim branches near the chimney and remove any accumulated leaves or twigs. A clear zone of at least 10 feet around the chimney reduces hiding spots for squirrels and birds.

4. Use natural deterrents. - Predator urine: Soak cotton balls in predator urine (available at garden stores) and place them near the chimney base. The smell deters smaller animals. - Ultrasonic repellents: These emit high-frequency sounds that annoy rodents and birds. They’re a low-cost ($30–$50) option for homes in wildlife-heavy areas like DuPont DuPont, WA. - Essential oils: Place cotton balls soaked in peppermint or eucalyptus oil near the chimney. The strong scents repel many animals.

5. Schedule regular chimney inspections. The Chimney Safety Institute of America (CSIA) recommends inspecting your chimney at least once a year, especially before winter. In Tacoma, where animals are active year-round, a spring inspection can catch early signs of nesting. At Luis G. Chimney Co., we offer discounted inspection packages for homeowners who book before October /news/october-chimney-sweep-checklist-tacoma-homeowners/.

6. Consider a chimney liner if yours is old or damaged. Older chimneys (especially those built before the 1980s) lack modern liners, making them prime targets for animals. A stainless steel liner ($1,500–$3,500) adds a protective barrier and deters nesting. While this is a bigger investment, it pays off in the long run by preventing damage and improving efficiency. For homes in Fife Fife, WA with older brick chimneys, liners are often the best preventative measure.

Local Tip: If you’re in a neighborhood with frequent wildlife sightings, like near the Tacoma Waterfront or the Old Town district, combine these steps for maximum protection. For example, a homeowner in South Tacoma installed a chimney cap, sealed mortar gaps, and placed ultrasonic repellents, reducing animal activity by 90% over two years.

What to Do If You Find a Dead Animal in Your Chimney (And How to Avoid the Mess)

Discovering a dead animal in your chimney is unsettling, but it’s also a fire hazard and health risk. Here’s how to handle it safely, and what to avoid:

Do NOT: - Reach in with your hands, this can damage the flue or expose you to bacteria from droppings. - Use a regular vacuum or shop vac, these can tear the liner or spread debris into your home. - Burn the fireplace, this can push soot and bacteria into your living space.

What to Do Instead: 1. Call a Tacoma chimney sweep immediately. A professional will remove the carcass safely using specialized tools. In Tacoma, crews often charge $200–$400 for dead animal removal, depending on the size and location. For example, a dead raccoon in a flue might cost $350 to remove, while a small bird could be $150.

2. Ask about disinfection. Animal carcasses leave behind bacteria and odors. A good crew will clean the flue and treat it with a disinfectant to prevent mold or mildew. Some companies in Tacoma offer this as an add-on service for $50–$100.

3. Check for damage. Animals decay quickly, and the process can weaken mortar or corrode metal components. The sweep should inspect for: - Rust or corrosion in metal flues. - Soft or crumbling mortar from acid breakdown (common with bird droppings). - Holes or gaps created by the animal’s movement.

4. Prevent future incidents. After removal, ask the crew to recommend preventative measures like a chimney cap or mesh screen. In neighborhoods like Point Defiance, where wildlife is abundant, these steps can save you from repeat visits.

Why This Matters in Tacoma: Tacoma’s climate, wet winters and mild springs, speeds up decay. A dead animal in a chimney can rot quickly, releasing foul odors and attracting pests like flies or rodents. The National Fire Protection Association (NFPA) warns that decaying organic matter in chimneys is a fire risk due to its flammable nature.

Real-Life Example: A homeowner in Lakewood Lakewood, WA called us after finding a dead opossum in their chimney. The carcass had been there for weeks, causing a foul smell throughout the house. Our crew removed it, cleaned the flue, and sealed gaps in the mortar, all for $320. Without professional help, the homeowner risked mold growth, structural damage, and a much higher repair bill later.

Pro Tip: If you suspect a dead animal but can’t see it, look for signs like: - A strong, rotting odor. - Flies or wasps near the chimney. - Dark stains or debris in the fireplace. These are clues that a carcass is present and needs professional removal.
