Radon Warning

The U.S. Environmental Protection Agency (EPA), the U.S. Surgeon General, and the Centers for Disease Control and Prevention (CDC) strongly recommend that ALL homebuyers have an indoor radon test performed prior to purchase or taking occupancy, and recommend having the radon levels mitigated if elevated radon concentrations are found. Elevated radon concentrations can easily be reduced by an NRPP Certified, or state-licensed, if applicable, radon mitigator. All homes should be tested regardless of geographic location or foundation type. Radon, a Class-A human carcinogen, is the leading cause of lung cancer in nonsmokers and the second leading cause overall”

  • Properly installed radon control systems will permanently reduce radon concentrations by up to 99%. Because most systems prevent soil air from entering the house, you may also notice other air quality improvement – like lower humidity.
  • Radon control systems will not decrease the home’s appraisal value; in fact, they are nationally accepted as a home improvement. Installations need little maintenance and operating costs are typically less than $10/month.
  • Radon systems are so effective at maintaining low radon concentrations and eliminating diurnal and seasonal fluctuations, living in a mitigated home reduces the occupant’s risk of radon-induced lung cancer to ALARA (as low as is reasonably achievable) – even lower than living in many houses that test below the EPA 4 pCi/L Action Level without a radon system.
