Frequently Asked Questions

How much does an air quality inspection cost in Pennsylvania?

Indoor air quality testing in Pennsylvania typically costs $200 to $600, depending on the number of contaminants tested and the property size. Basic radon testing costs $150 to $250. Comprehensive IAQ testing that includes mold spores, VOCs, particulates, and radon costs $400 to $600.

Why is radon testing especially important in Pennsylvania?

Pennsylvania has some of the highest indoor radon levels in the United States. Approximately 40% of PA homes have radon levels above the EPA action level of 4 pCi/L. The PA DEP provides free radon test kits to residents and strongly recommends testing every home, regardless of location within the state.

What does an indoor air quality inspection test for?

A comprehensive IAQ inspection tests for radon, mold spores, volatile organic compounds (VOCs), carbon monoxide, carbon dioxide levels, humidity, particulate matter, and formaldehyde. Some tests also screen for allergens, bacteria, and chemical off-gassing from building materials. The scope depends on your concerns and symptoms.

When should I get an air quality inspection in Pennsylvania?

Get an air quality inspection if occupants experience unexplained respiratory issues, headaches, or allergies that improve when leaving the building. Also recommended after water damage, renovations, or when buying a home. All Pennsylvania homes should have radon testing performed at least once, and re-tested every 2-5 years.
