Attic cleaning removes allergens and respiratory irritants that can make your family sick.
â€œNo one thinks about their attic, but itâ€™s a problem area,â€ says Mike Tringale of the Asthma and Allergy Foundation of America.
Attic allergens and irritants constantly seep into your living area through ceiling hatches, doors, recessed lights, and heating and cooling systems (especially if theyâ€™re located in your attic).
Attic cleaning basics
Keeping irritants out of your attic
Preventing mold growth and sealing out insects and vermin helps reduce irritants in your attic.
Mold: Small roof leaks and old, cracked caulking can let in moisture, which may lead to mold damage. Once a year, and after each big storm, walk around your home to inspect your roof from all angles. Repair any loose, missing, or broken shingles. Check windows for missing caulking or cracked panes.
Donâ€™t bother buying a home mold test kit, which may register mold spores that are constantly in the air anyway. If you suspect mold, or can see a mold-covered area thatâ€™s larger than about 10 sq. ft., call a certified indoor air quality professional to evaluate your situation.
Dust: Many of those tiny dust mites you see floating around are really dust mite particles, roach parts, and vermin dander made of dried saliva, urine, and feces.
These dust proteins can trigger allergic reactions, so search for tiny cracks and openings in your roof, walls, and windows where vermin and insects can enter. Seal attic air leaks with caulk and polyurethane foam, and repair any holes in attic ventilation screens that are under the eaves and in gable ends.
