You should re-test for radon shortly after your mitigation system is installed, usually after the system has had time to run and stabilize. A post-installation radon test confirms that the system is lowering radon levels and working as expected.
After installing a radon mitigation system, you should re-test your home to make sure the system is doing its job. The system needs a little time to run first, but you do not want to wait too long. The point of the follow-up test is simple: confirm that radon levels have dropped and that the system is pulling radon out of the home the way it should.
Most homeowners use a short-term radon test after installation. This gives a clear before-and-after comparison without dragging the process out for months. If the system was installed during a real estate transaction, timing may be tighter, so your mitigation company can explain when the post-test should happen and what documentation may be needed.
Radon Mitigation in Minneapolis / St. Paul MN.
Radon levels can shift because of weather, seasons, soil conditions, and how the home is used. That is normal. A good post-mitigation test shows whether the system is keeping levels down under typical conditions.
It is also smart to keep testing over time. Even a well-installed radon mitigation system should be checked periodically because fans age, homes settle, and changes to the foundation or lower level can affect airflow.
