Quality radon testing and radon removal for Ohio properties

Radon levels in Ohio vary, but any home regardless of location or age could be susceptible to high levels of this dangerous gas. You have a right to know your home's radon levels so that you can ensure that your family stays safe.

As an odorless, tasteless, colorless gas, radon cannot be traced by the human senses. Luckily, it can easily be detected by a professional radon test and can be mitigated and reduced to a healthy level.

It's every Ohio homeowner's dream to maintain a healthy, safe home, and there's no reason your home should be anything but that!

National Radon Defense's Ohio dealers are highly trained in radon mitigation

Each home in Ohio is different, and every home has a different radon level. Be sure to contact the radon mitigation experts from National Radon Defense today and schedule your home inspection and mitigation.

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.

    I compared you with someone who has been doing this for 18 years. The MAIN reason I chose your company was Evan. From the beginning, he was helpful in every way that I needed. He was on time, he answered all my many questions over countless e-mails, and he was always very patient with me. He never lost his smile, rushed me in any way, or made me feel as if my best interest was not his main concern. He radiates caring and honesty. I found Evan to be extremely competent, knowledgeable, and just a joy to be around. It appeared as if he truly loved his work and helping people. He is a rare gem and I hope he is appreciated by your company. I look forward to working with him in the future. I will certainly recommend him and your company to all my friends, neighbors, and family.
