"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

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
