When performing radon testing in real estate transactions, it is typically best to hire a licensed radon tester. Your contractor should provide you with directions on how your home should be during this test, as well as where he or she is conducting the test. If you are in need of radon testing in real estate, Trinity Radon can connect you with a licensed radon tester. This is a brief overview on how radon testing in real estate transaction typically looks.

House conditions when Radon testing in Real Estate

Be aware that any test lasting less than three months requires closed-house conditions.
Closed-house Conditions: Mean keeping all windows and doors closed, except for normal entry and exit.

Before Testing: Begin closed-house conditions at least 12 hours before the start of the radon test.

During Testing: Maintain closed-house conditions during the entire duration of the short term test. Operate home heating or cooling systems normally during the test.

Where the test should be conducted

Any radon test conducted for a real estate transaction needs to be placed in the lowest livable area of the home suitable for occupancy. In Illinois, this is typically in the basement, whether it is finished or unfinished.

The test kit should be placed:
• two to six feet above the floor
• at least three feet from exterior walls
• four inches away from other objects
• in a location where it won’t be disturbed • not in enclosed areas
• not in areas of high heat or humidity

If the house has multiple foundation types, it is recommended that each of these be tested. For instance, if the house has one or more of the following foundation types–basement, crawl space, slab-on- grade–a test should be performed in the basement and in at least one room over the crawlspace and one room with a slab-on-grade area.

"The technicians at Trinity services were extremely professional. It was a pleasure to open up our home to them. My wife and I were extremely impressed with how neat and clean they worked. A lot of contractors just don't care, but I could tell that Trinity was not one of those contractors."

Bruce – Naperville, IL

"I met Josiah last week when he came out to 310 S Rosedale in Aurora to consult with my clients about the house they are buying. I was very impressed by both his knowledge and wiliness to answer questions. Far too many in the trades are not quite so customer centric. In any case, it is my pleasure to recommend your company to other agents and to my own clients in the future."
