The walls and ceiling of your attic often have cracks and gaps that allow rainwater, dust, insects, and other pests to enter. As dust and moisture accumulate, mold and mildew can develop, attracting rodents and other pests. Not only do these infestations pose a threat to your indoor air quality and health, but the moisture also dampens your insulation, lowering its energy efficiency. If you haven’t cleaned your attic in a while or notice these signs of neglect, it’s time to call a professional attic cleaning service like Evergreen Attic Insulation to address the issue.
