Radon Detection and Reduction questions, answered by experts

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.
