"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

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.

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.

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).

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.
