After you've installed a radon mitigation system, a radon retest is your confirmation that the system is actually working. You wait at least 48 hours, run the test in the same lowest lived-in area, and seal it up tight for accurate results. It's the step that tells you if your home is truly back to safe levels or if you need to call the contractor back to tweak the setup. It's a small effort for the peace of mind that comes with knowing your family's exposure is under the EPA's action level.
