What to Do After a High Radon Test

An elevated radon result gives you a measurable problem to address. The next step is to review the result, understand how the test was performed, and determine whether follow-up testing or mitigation is appropriate.

4 pCi/L or Higher

EPA recommends fixing homes when radon is at or above 4 pCi/L. EPA also says homeowners should consider reducing levels between 2 and 4 pCi/L.

Do I Need Another Test?

The answer depends on the testing circumstances, result, building, and applicable protocol. A professional can review the existing result and explain the available next steps.

If Mitigation Is Recommended

A mitigation system is designed to reduce radon entering and accumulating inside the building. After installation, follow-up testing helps determine whether the system is performing effectively.
