Common Intruders
Animals Commonly Found in Allen Chimneys
An uncapped chimney flue is a dark, warm cylinder that mimics a hollow tree trunk, making it a prime nesting spot for Texas wildlife:
Raccoons: Female raccoons frequently climb down chimneys in the spring to give birth. They build thick nests on the damper. Attempting to start a fire to smoke them out is highly dangerous and cruel – it will suffocate the babies, creating a terrible smell and a permanent biohazard block in your wall.
Squirrels: Unlike raccoons, squirrels cannot easily climb back up a smooth metal or glazed clay flue liner. If a squirrel falls in, it will scratch frantically against the metal walls. These situations are urgent, as a trapped animal will pass away in the flue within 3 to 4 days, causing a severe odor and fly infestation.
Birds (Chimney Swifts): These small migratory birds cling to the vertical brick walls of flues. They are protected under the Federal Migratory Bird Treaty Act, meaning active nests cannot be removed until the chicks hatch and depart (generally May through August). We can help identify if the nest is active and schedule capping as soon as they leave.
