Dangers of a Blocked or Infested Flue
An open or un-capped chimney is an inviting shelter for wildlife like birds, squirrels, raccoons, bats, and rodents seeking a warm, dry nesting spot. Unfortunately, animals, twigs, leaves, and trash can completely block your flue, creating severe smoke backdrafts, foul odors, and dangerous carbon monoxide (CO) traps.
Our humane, certified technicians safely remove wild animals, nests, and organic blockages from your chimney system, sanitizing the flue and installing heavy-duty protective covers to keep pests out permanently.
Allowing animals or debris to remain inside your chimney poses immediate risks to your home, health, and fire safety:
- Carbon Monoxide Poisoning: Animal nests made of twigs, leaves, and mud act as solid plugs, trapping deadly carbon monoxide (CO) gas inside your living space when you light a fire or turn on your furnace.
- Severe Smoke Backdrafts: Blocked exhaust paths force thick, toxic smoke and ash back out through your fireplace or stove opening, causing severe indoor air pollution and soot damage.
- Foul Odors & Parasites: Deceased animals or nesting waste generate overpowering odors, attracting flies, fleas, ticks, and maggots directly into your home.
- Chimney Fire Hazard: Dry twigs, grass, pine needles, and animal bedding inside a flue are highly combustible and ignite instantly under high temperatures.
Our Safe & Humane Removal Process
We use specialized tools and humane wildlife removal protocols to clear your flue without damaging your chimney or property:
- Diagnostic Camera Sweep: We run an internal video camera down the flue to identify the exact location and type of blockage (e.g., active nest, deceased animal, fallen brick, or leafy debris).
- Humane Extraction: Live animals are safely and humanely trapped or guided out in accordance with local wildlife protection laws.
- Nesting & Debris Extraction: Using specialized mechanical hooks, rods, and heavy-duty HEPA containment vacuums, we extract all twigs, leaves, feathers, and mud deposits.
- Sanitization & Deodorization: We treat the flue and firebox with eco-friendly, non-toxic antimicrobial sprays to eliminate bacteria, parasites, and lingering animal odors.
- Prevention & Chimney Cap Installation: We install heavy-duty, stainless steel or copper chimney caps with welded mesh screens to guarantee animals and debris can never enter again.
Chimney Swifts: A Special Wildlife Warning
If you hear loud, bird-like twittering or chirping coming from your flue during late spring or summer, you likely have Chimney Swifts.
Important Note: Chimney Swifts are migratory birds protected by federal law under the Migratory Bird Treaty Act. It is illegal to disturb, harm, or remove active Chimney Swift nests containing eggs or chicks. Our technicians inspect for swifts, advise you on protection timelines, and schedule safe clearance and capping after the chicks have naturally fledged in the late summer.
Signs You Have an Animal or Blockage in Your Chimney
- Scratches, Flapping, or Chirping: Hearing rustling, thumping, or high-pitched animal noises behind the damper or inside the walls.
- Strong Odors: A foul, decaying smell or intense ammonia (urine) odor coming from the fireplace hearth.
- Fallen Debris in the Firebox: Finding twigs, leaves, feathers, nesting material, or animal droppings on your hearth floor.
- Smoke Rolling into the Room: Lighting a fire and having smoke immediately billow out into your living area due to zero upward draft.
