About This Service
An uncapped Colorado chimney is prime real estate — raccoons den in smoke chambers, squirrels stash pinecones in flues, and birds nest on smoke shelves every spring. Animal removal gets wildlife out humanely, clears the nesting debris that's a genuine fire hazard, and closes the door behind them.
One important note: chimney swifts are federally protected migratory birds, and active nests legally must stay until the young fledge. We identify what you're hearing, handle protected species correctly, and schedule exclusion for the moment it's legal and effective.
Signs You Need Chimney Animal Removal
- Scratching, chirping, or thumping from the fireplace
- Visible nesting material at or above the damper
- Odors of animal activity from the firebox
- An uncapped flue and active wildlife in the neighborhood

How Removal Works
We identify the species first — it determines the legal and humane approach.
Removal or (for protected swifts) scheduling around fledging.
All nesting material and debris cleared; the flue swept if needed.
Exclusion hardware installed so this is the last time.
Why It Matters for Safety
Nesting material is dry tinder stacked inside a fire conduit, animal blockages push combustion gases back into living space, and wildlife in a flue can carry parasites and disease. Humane removal plus exclusion resolves the hazard without harming the animals.
Maintenance Tips From Our Technicians
- Keep caps screened on every flue — exclusion beats eviction, always.
- Trim branches that overhang the chimney; they're wildlife on-ramps.
- Spring scratching sounds mean act fast, before nesting is established.
- After any animal event, sweep before burning; nests are tinder.

Frequently Asked Questions
There's an animal in my chimney right now — what should I do?
Don't light a fire and don't open the damper into the house. Close glass doors if you have them and call us — most removals are same-day, and panicked-animal-in-living-room is the outcome we're both trying to avoid.
How do you keep animals from coming back?
A stainless cap with animal screening over every flue, and sealing any gaps at the crown. Exclusion is permanent when the hardware is right — it's the last animal call you should need.
Are you licensed and insured?
Fully. Donovan Chimney & Fireplace carries the licensing and insurance this work requires, and certificates are available on request — something we recommend asking of any company that climbs on your roof.
