"Great people, honest and fair. I have confidence that the system they installed is the best. Radon NC used top quality materials and their guarantee is comprehensive. I almost went with a "national" company but I compared their estimate to Radon NC and there's no comparison. Affordable Environmental Services guarantee their work and use the best materials, not the cheapest. I recommend this company!"

"During our 2017 annual dehumidifier service appointment, The Mold Hunter, Inc. found the equipment not to be working properly. I then began the process of pursuing a warrantied repair by shipping our Horizon dehumidifier back to the manufacturer, Air Cleaning Equipment, Inc, of Sanford, NC. After 7 1/2 months of not only supporting my efforts, but intervening directly on my behalf, Mike Smith did what Air Cleaning Equipment, Inc. would not do - he stood behind his work and the equipment he installed, and replaced the unit with a product from another manufacturer. Mike Smith is a business owner and individual of exceptional character. I highly recommend his company, The Mold Hunter, Inc. to anyone needing water restoration or mold remediation."

Radon Detection and Reduction FAQs, answered by experts

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Installation typically takes 1-2 days, depending on the system and property layout.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.
