Why open flues attract animals here
South Florida’s mild climate means active wildlife year-round, so there’s no “off season” for a critter looking for a sheltered spot. An uncapped flue, or one with a rusted-out or torn cap, is an open invitation. The most common issues we see are birds nesting in the flue (including species that specifically seek out chimneys), squirrels using the flue as a highway, and larger animals like raccoons getting into a wide, unprotected flue or chase.
What prevention actually involves
- A properly sized, well-built chimney cap with intact spark-arrestor mesh. This is the core of animal prevention — the mesh keeps animals out while letting smoke through. Most animal-entry problems trace straight back to a missing, damaged, or wrong-mesh cap.
- Multi-flue caps or custom guards for chimneys with several flues or unusual openings.
- Sealing other entry points around a prefab chase where gaps have opened up.
- Assessment first: confirming nothing is currently living in the flue before it’s capped — because sealing an animal in creates a worse problem than the one you started with.
The honest limits — and why they matter
We don’t cap a flue that’s occupied. Capping over an active nest or a trapped animal is inhumane and creates odor, blockage and a mess. If there’s a chance something is living in there — especially during nesting season — that has to be resolved first. Some protected species (certain chimney-nesting birds among them) also have legal protections around nesting periods. Where removal or a protected-species situation is involved, that’s wildlife work, and we’ll point you to the right resource rather than overstep what we do.
What you might be noticing
Common signs of an animal in the flue: scratching, scurrying or chirping sounds (especially in the morning), a sudden bad smell, debris falling into the firebox, or a fireplace that suddenly drafts poorly because a nest is blocking it. If you’re hearing or smelling something, don’t light a fire — and don’t cap it yet. Let’s confirm what’s going on first, resolve any occupant appropriately, and then close the flue so it doesn’t happen again.
Questions people ask us
There’s an animal in my chimney right now — can you get it out?
Our service is prevention — the caps and guards that keep animals out — and assessment, not active trapping or removal, which is separate, regulated wildlife work. Importantly, we won’t cap a flue with something living in it. If there’s an animal in there now, that needs to be resolved first (and some nesting birds are legally protected); we can advise on the right next step and then seal the flue so it doesn’t recur.
Will a chimney cap really keep animals out?
A properly sized cap with intact spark-arrestor mesh is the single most effective barrier — most animal-entry problems come down to a missing, torn or wrong cap. We make sure the mesh and fit are right for the wildlife common here, and that it’s secured against wind.
I hear scratching but I’m not sure what it is — should I just cap it?
No — don’t cap it until we know the flue is empty. Sealing an animal inside causes odor, blockage and a much bigger problem. Let us assess first, make sure nothing’s living in there, and then cap it. If something is nesting, we’ll point you to the appropriate resource before closing it up.
