Oregon radon testing and radon removal

Certain areas of Oregon are known for having higher radon levels, such as NW Oregon, including the Columbia Gorge and Willamette River Valley. While radon exposure is considered a concern in these areas, it is also just as likely in any other OR location. Even two homes side by side can have drastically different radon levels, so it's extremely important to have your home tested for radon regardless of where you live.

The good news is, your beautiful Oregon home does not need to fall victim to the effects of radon gas. We at National Radon Defense want to help purify your home and maintain your home's healthy radon level.

No indoor environment is safe until a radon test has been completed and, if high levels of radon are discovered, a radon mitigation system has been installed.

That's why the team at NRD wants to help homeowners like you to maintain a healthy radon level in your home. Radon is a serious problem, and we're the best-trained radon experts in your area!

We Provide:
  • Radon testing
  • Radon mitigation systems
  • Multi-family radon testing & mitigation
  • Vapor intrusion mitigation
  • Indoor air quality services
You Receive:
  • A healthy home environment
  • Clean indoor air
  • Protection for you and your family
  • Safe radon levels
  • Peace of mind
Although no homeowner wants to increase cancer risks for family members, many people neglect to test their homes for radon, an invisible, odorless, cancer-causing gas that emanates from soil and rocks. Contacting a radon mitigation specialist to perform a radon test, or conducting your own test with a DIY radon test kit is the first step in protecting your family from hazardous levels of radon gas.
