Radon Testing FAQs
How long does a radon test take?
Most real estate tests run for 48 hours. We place a calibrated continuous monitor and retrieve it after the test period, then send your results—usually the same day.
Do I need to prepare the home before testing?
Yes—“closed-house conditions” help ensure accurate results. Keep windows and exterior doors closed (except normal entry/exit), avoid running whole-house fans, and maintain normal HVAC use during the test.
What radon level is considered high?
In the U.S., the common action level is 4.0 pCi/L. If results meet or exceed this level, mitigation is typically recommended. Some homeowners also choose to mitigate between 2.0–3.9 pCi/L to further reduce risk.
Can I order a radon test without a home inspection?
Absolutely. We offer stand-alone radon testing as well as add-on testing paired with a home or light commercial inspection.
Do you test in Jefferson City as well as Columbia?
Yes—we regularly test in Columbia, Jefferson City, Ashland, Fulton, and nearby Mid-Missouri communities.
