Frequently Asked Questions
How much does an air quality inspection cost in Illinois?
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 Illinois?
Illinois has varying radon levels depending on geology. Winnebago, McHenry, Lake, Kane, DuPage, DeKalb, and most central Illinois counties sit in EPA Radon Zone 1 and are areas of particular concern with elevated radon risk. The University of Illinois Extension and IEMA's Illinois Radon Program provide county-specific radon data showing elevated risk zones. 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 Illinois?
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.
