After installing a radon mitigation system, testing is crucial to confirm it's working. This post-mitigation radon testing involves placing a detector in the lowest livable area for at least 48 hours, often during winter when radon levels peak. Results showing levels below the EPA action limit of 4 pCi/L mean your system is performing well, giving peace of mind that your home's air is safer.
