Radon Testing for Fairfax County Real Estate

Radon testing is often requested during home inspections in Fairfax County. A professional radon report helps buyers understand potential health and mitigation considerations before closing. Sellers can also benefit from pre-listing testing because it can reduce surprises, support transparency, and make the listing process smoother.

What Happens During the Test?

Before and during the test, closed-house conditions should be maintained. Our technician places the monitor in the lowest suitable livable area of the property. After the 48-hour monitoring period, we retrieve the device, review the data, and deliver a digital report.

The report includes the average radon level, hourly readings, property and placement information, testing dates, and next steps if elevated levels are detected.
