Radon Testing


Obtaining radon testing is one of the most important steps you can take to protect the health of your family when buying a home. Radon studies estimate that 1 out of 4 homes in the Mid-Columbia area have elevated levels of radon that should be mitigated. It can be relatively easy to mitigate radon if discovered in your new home, but it’s best to get a professional test done before closing your real estate transaction so you’ll be able to negotiate the costs of mitigation into your purchase agreement.

Radon monitor

CGI is IAC2 Certified and offers professional level radon testing that follows the EPA’s guidelines for real estate transactions. Using continuous electronic radon monitors allows for instantaneous results after the minimum testing period. Tests run for 2 days under “closed home conditions” (meaning normal entry and exit, but not leaving windows and doors open). At the end of the test, you will be provided with the report that gives you overall radon levels as well as hourly readings throughout the length of the test.

What Is radon?

Radon is a naturally occurring radioactive gas that is formed when byproducts of uranium break down. Radon is odorless, tasteless, and invisible to the naked eye. While radon may not be readily apparent, the damaging effects of radon exposure to your family can be devastating. For nonsmokers, the Surgeon General warns that radon is the leading cause of lung cancer in the United States and causes over 21,000 deaths a year. Depending on your neighborhood, radon levels can be particularly high in the Mid-Columbia area, putting you and your family at risk.
