How often should you retest your home for radon?

Retesting your home for radon every two years is the recommended practice, as radon levels can fluctuate due to various environmental factors, such as changes in building structure, ventilation, and weather conditions. Conducting a radon test at this interval allows homeowners to effectively monitor any changes in radon concentrations and address potential risks promptly.

Annual testing may seem prudent; however, for most homes, a biennial schedule provides a balance of sufficient monitoring without excessive testing burden. While retesting every five years or ten years may seem convenient, such extended intervals could allow significant variations in radon levels to go unnoticed, potentially exposing residents to harmful levels of this radioactive gas. Therefore, retesting every two years is the optimal recommendation to ensure ongoing safety and awareness regarding radon exposure in homes.
