"Had them come out to install a Radon Mitigation Fan. Service was fast and the installer was extremely knowledgable. He was in an out within an hour and the radon dropped from a 4 to a 0.59! Extremely happy with the result. Price wasn't cheap by any means but definitely fixed our problem."

"Once they started working on it, the work was great. What they did was good, but they forgot to put caulking on one of our skylights. They came back quickly to fix it. We put half the money down and then we didn’t hear anything for 4 months. I guess they were switching company owners, but since then it has been good."

Radon Detection and Reduction questions, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.
