"We hired Mr. Joeseph Danes, owner, of Apex Radon LLC in Boise, to mitigate radon in our home. This was not a simple project: our house has a partial slab, a section of full basement, and two crawl spaces. Apex Radon LLC was the only Boise company that could conduct under slab pressure tests. We admit that we are not the easiest homeowners to work with â two retired mechanical engineers. Other contractors have likely found us exasperating. To our delight, Joeseph matched our high standards and attention to detail. We found him to be hard working, very knowledgeable, thorough, professional, and personable. Because of our homeâ s complexity, Mr. Danes designed a two-stage system. Stage 1 has been installed and radon concentration throughout the house has already dropped below the USA recommended level. This may change in the winter when frozen ground can cause indoor radon to increase. If so, we will gladly hire Apex Radon to install Stage 2."

Radon Detection and Reduction questions, answered by experts

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

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.

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