Pennsylvania's authorized radon testing & radon mitigation contractors

According to the PA Department of Environmental Protection, an estimated 40 percent of Pennsylvania homes have radon levels above 4.0 pCi/L. The Environmental Protection Agency has established 4.0 pCi/L and higher as a dangerous level of radon exposure at which health risks become very serious. That's why it's essential for PA homeowners to have their homes tested for radon levels and, if needed, install a radon mitigation system to restore health and safety to the indoor air.

Since radon gas is caused by the natural process of uranium decay, and uranium is found in most soil, radon is not limited to affecting just one state or area of the world. It can be found in any home, anywhere.

The National Radon Defense has designed a system to produce the nation's finest radon specialists in Pennsylvania, and our certified contractors are fully qualified for both radon testing and radon abatement. It is our goal to properly inform the public of the radon hazards and the benefits of radon mitigation.

National Radon Defense dealers are the best in the industry

There's absolutely no reason why you and your loved ones have to suffer from the dangerous effects of radon gas. Contact the radon mitigation specialists at NRD today to mitigate your Pennsylvania home.

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.
