"I have never used a home inspector previously, but I am glad that I hired Johnson Properties and Inspections and stayed with him during the lengthy home inspection. Mr. Johnson is a very thorough and knowledgeable inspector and provided a detailed inspection report with color pictures by email within 24 hours. The radon and water testing results were also quite useful, but took longer to return since the tests have to be sent out. Although not all items had to be addressed before closing, I now have an informed idea of all items relevant to my purchase and a to do list for items that I will need to take care of in the future."

Radon Detection and Reduction questions, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

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

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Installation typically takes 1-2 days, depending on the system and property layout.
