Frequently Asked Questions
How much does an air quality inspection cost in California?
Indoor air quality testing typically costs $300 to $700 for a standard assessment. Basic radon testing costs $175 to $300. Comprehensive IAQ testing including mold spores, VOCs, particulates, and radon costs $500 to $800. Testing for additional regional contaminants may add to the cost.
Why is radon testing especially important in California?
California has varying radon levels depending on geology. **Granitic foothill areas (for example along the Sierra Nevada)** are of particular concern with elevated radon risk. **UC Agriculture and Natural Resources (UC ANR / UC Cooperative Extension)** and the **California Department of Public Health (CDPH)** Radon Program provide county-level radon data and guidance. Testing every home is recommended.
What does an indoor air quality inspection test for?
A comprehensive IAQ inspection tests for radon, mold spores, volatile organic compounds (VOCs), carbon monoxide, humidity, particulate matter, and formaldehyde. Testing for industrial VOCs may be relevant near former industrial sites due to potential legacy contamination.
When should I get an air quality inspection in California?
Get an air quality inspection if occupants experience unexplained respiratory issues, headaches, or allergies. Also recommended when buying a home (radon testing is critical), after water damage or flooding, after renovation, or if your home is near a brownfield site or industrial area.
