critical Hazard 1 of 6

Radon Gas

Radon is the #2 cause of lung cancer after smoking. It seeps from soil into basements and crawl spaces. You cannot see, smell, or taste it. The only way to know is to test.

Mold Exposure

Mold releases spores that trigger allergies, asthma attacks, and respiratory infections. Black mold (Stachybotrys chartarum) produces mycotoxins linked to neurological symptoms.

Asbestos Fibers

Asbestos causes mesothelioma, lung cancer, and asbestosis. Homes built before 1980 likely contain asbestos in insulation, floor tiles, and pipe wrapping. Disturbing it releases deadly fibers into the air.

High Indoor Humidity

Humidity above 60% creates ideal conditions for mold, dust mites, and bacteria. It also increases off-gassing of VOCs from furniture and building materials. The EPA recommends 30-50% indoor humidity.

Cockroach and Pest Allergens

Cockroach saliva, feces, and decomposing body parts become airborne allergens. They are a major trigger for asthma in children, especially in urban environments. Mouse urine proteins cause similar reactions.

Basement Air Quality Hazards

Basements accumulate the worst indoor air hazards: radon, mold, chemical storage fumes, and pest allergens. Because warm air rises, basement pollutants circulate throughout the entire home through the stack effect.
