Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Listen carefully at different times of day to identify patterns in the noise (nesting vs. trapped).
Step 2
With the damper open and the fireplace cold, use a strong flashlight to look up the flue for obstructions or eyes.
Step 3
If it's safe to do so, visually inspect the top of the chimney from the outside for a missing cap, nesting material, or visible animals.
Step 4
Attempt to identify the animal by its specific sounds (chirping, chattering, growling) to determine the risk and removal method.
Step 5
If you've recently used the fireplace, note any issues with smoke drafting into the room, which signals a critical blockage.
