Our Process

When you contact Oak City Radon we will work with you to figure out the best time to conduct the 48-hour radon test. Throughout the test, all exterior doors and windows should remain closed, other than normal entry and exit. For new construction homes, the best time to run a test is typically on Friday (with a 12-hour delay), so the test will run from late Friday/Early Saturday to Sunday while contractors are not working in the house.

* For new construction houses, the home needs to be as complete as possible. This includes having the HVAC system operating normally, weather stripping installed on exterior doors, and being free of contractors.

Closed-House conditions are required for the duration of the test. These conditions include:

• Keeping all windows and doors closed (aside from normal entry and exit)
• Keeping ceiling fans turned off in the room where the radon test is set up
• Keeping the temperature set between 64-78 degrees

We typically try to avoid testing new construction homes Monday through Friday when most contractors are coming and going – many project managers prefer we come on a Friday to set up the test and put it on a 12-hour delay so the test runs from Saturday to Sunday.

To ensure anyone going inside the property during the test is aware of the closed-house conditions, Oak City Radon will put up signs at each entry point.

Once you have decided the best testing period and can ensure Closed-House conditions, please contact Oak City Radon to schedule your radon test:

To accelerate the scheduling process, please provide:

* Once we receive your request for a radon test, we will confirm and collect any additional information needed.

The appointment typically only takes a couple of minutes to set up the continuous radon monitor, explain the Closed-House conditions to our client, and post any necessary signs. We will also leave a note and our contact information in case there are any additional questions or concerns.

• All windows/exterior doors will be closed
• Fans will be turned off in the room with the monitor
• The thermostat will be set between 64-78 degrees

Our monitor will record 48 hourly radon measurements to determine an overall average.

After the test is complete we will return to pick up the equipment and will be able to see the result immediately. You will receive an email the same day with a radon test report included. This report will contain a test summary, including a graph, showing you all 48 readings recorded during the test, as well as the average radon level.

Interpreting your radon test results:

• Nationwide average indoor radon level: 1.3 pCi/L
• Nationwide average outdoor radon level: 0.4 pCi/L
• EPA action level: > 4.0 pCi/L

* The EPA estimates that one in every 15 homes nationwide has radon levels at or above 4.0 pCi/L.
