Radon-Resistant Features Do Not Replace Testing

A newly built home can have radon-resistant features and still need testing. EPA recommends testing new homes even when those features are installed. A passive system may need a fan to become an active system, depending on the test results. See EPA’s guidance for buyers of newly built homes.

Questions to Ask Your Builder

• Were radon-resistant features installed, and where is the system documentation?
• Is the system passive or active, and who can explain its operation?
• Has the completed home been tested, and can you review the results and test conditions?
• If follow-up is needed, who will coordinate it and when can testing be completed?

Understanding the Result

EPA recommends fixing homes with radon levels at or above 4 pCi/L and considering reduction between 2 and 4 pCi/L. The action level is not a boundary between safe and unsafe exposure. Review EPA’s action-level explanation and discuss results and follow-up with a qualified radon professional.

Plan Testing Around Construction and Closing

Tell Realm about the construction stage, access, utilities and closing deadline when scheduling. Required test conditions must be maintained; a busy construction site may not yet be ready. Realm’s radon testing requires a minimum of 48 hours of collection. Reports are typically available 5–7 business days after the inspection or monitor deployment. That timeline is separate from the home inspection report, which is expected by the end of the next business day after the inspection, barring unusual circumstances.

Request a Project-Specific Estimate

Ask a qualified contractor for an estimate based on the home’s construction and existing system. An older published cost range is not a quote for your property. Realm’s testing does not itself include installation or guarantee the performance of a mitigation system.

Contact Realm Inspections to discuss testing and scheduling.
