An independent study of America's basements.

Founded in 2026, the Healthy Basement Society conducts non-commercial, neighborhood-level research on basement moisture and foundation health across the United States.

Aggregated, anonymized data — never individual surveillance.

The Healthy Basement Society conducts independent neighborhood-level research on basement moisture and foundation health patterns across the United States. Our mission is to provide homeowners and professionals with actionable, aggregated data — while maintaining the highest standards of data privacy and research ethics.
