Blue Sky works with these kinds of buildings:
- homes — thousands of special problems just discovered, or whole house suspected, or clean but concerned (most needed unbiased advice).
- apartments / condominiums — hundreds of moldy basement units, dusty carpeted units (many needed air filtration).
- offices — hundreds of lone offices, or entire buildings, and their ventilation systems, usually where workers were suspicious (most needed better ventilation airflow).
- schools — dozens of classrooms, portables, schools (most needed better dust control).
- commercial properties — many unique conditions with contaminated complications (most needed better hygiene).
