Radon Testing: Why InterNACHI® Certification Ensures Accurate Results You Can Trust

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 you can have performed in your home. When your family's safety depends on accurate results, InterNACHI® certified home inspectors provide the expertise and integrity you need for reliable radon testing.

Many radon mitigation companies have a bias towards 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. InterNACHI® certified inspectors abide by a Code of Ethics and focus solely on providing accurate testing and are restricted from selling follow-up services.

InterNACHI® certification requires comprehensive training in proper radon testing protocols, including correct placement of testing devices, maintaining proper testing conditions, and understanding factors that can affect results. This education, provided by the only accredited home inspector college, ensures that your test follows governmental guidelines and produces reliable data you can use to make informed decisions about your family's safety.

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.

InterNACHI® 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 you toward specific contractors.

Your family's protection from radon exposure starts with accurate, professional testing by someone with no agenda beyond your safety.
