Raccoons, squirrels, birds, and bats commonly invade uncapped chimneys in East Providence. Raccoons use chimneys as den sites, especially during spring breeding season when they need safe spaces for babies. Squirrels fall in while exploring and can’t climb back up smooth metal flue liners. Birds like starlings and pigeons get trapped and die inside chimneys, creating health hazards and terrible odors. Even chimney swifts, which naturally nest in chimneys, can become problematic when their nests block proper ventilation. Professional chimney cap installation with animal guards prevents all these intrusions while maintaining proper ventilation. It’s far easier and cheaper to install protection than to remove dead animals, clean contaminated areas, and repair damage from nesting materials.
