The team of radon mitigation contractors 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!

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.
