"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

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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

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).

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