"Avert Radon LLC , specifically Chance, recently completed radon mitigation work at my residence, installing two systems. I typically refrain from writing reviews, but felt compelled to share my experience with Avert Radon LLC . I'm extremely satisfied with the results, as the radon levels are now virtually undetectable. Chance demonstrated exceptional professionalism throughout the process. The communication was excellent, and their meticulous attention to detail was also outstanding. Furthermore, their post-installation follow-up has been consistently excellent. I highly recommend this company without reservation. They are among the best service providers I've encountered. if I could give it more than five stars, I certainly would!"

Radon Detection and Reduction questions, answered by experts

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.
