Radon is the number one cause of lung cancer in non-smokers. Radon is an invisible, odorless gas that causes thousands of lung cancer deaths annually, making proper testing one of the most important health assessments that can be performed in a home. When safety depends on accurate results, certified home inspectors provide the expertise and integrity needed for reliable radon testing.

Many radon mitigation companies have a bias toward finding problems because they also sell expensive radon mitigation systems. This conflict of interest can lead to questionable testing practices, inflated results, or unnecessary remediation recommendations. Certified inspectors typically adhere to a strict Code of Ethics, focusing solely on providing accurate testing and are often restricted from selling follow-up mitigation services, thus maintaining professional objectivity.


Certification requires comprehensive training in proper radon testing protocols, including correct placement of testing devices, maintaining appropriate testing conditions, and understanding factors that can affect results. This specialized education ensures that tests follow established governmental guidelines and produce reliable data that homeowners can use to make informed decisions about their property.


Certified home inspectors understand how building systems affect radon levels. They can identify ventilation issues, foundation problems, and other factors that influence radon entry and accumulation. This building science knowledge helps ensure accurate testing conditions and provides valuable context for interpreting results.


Certified inspectors use calibrated, professional-grade testing equipment and follow strict chain-of-custody procedures that ensure reliable results. Their training includes understanding when retesting is necessary and how different testing methods affect accuracy.


When radon testing reveals elevated levels, certified inspectors can provide unbiased guidance about mitigation options without steering clients toward specific contractors.
