"Super customer service! Everything was totally explained to me and what needed to be done on installation. Brett was very informative & by the time he explained everything to me, I didn't have any questions. Brett was very professional but also easy to talk to. I love to support local businesses & EEHI LLc is that kind of company. All work was guaranteed. I strongly suggest you book an appt. with EEHI. My radon count went from a 10 to a .02 when he came back for final reading! I feel so much safer now! Super company & Brett was fantastic! Book with this company because they are so honest!!

Radon Detection and Reduction questions, answered by experts

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
