Today I’m joined by David Reemer from Quality Inspection Services to help me cover an important topic: radon. David is my favorite home inspector, and also happens to be a radon specialist. Radon can pose a big threat to you and your family’s health, so knowing how to mitigate it in your home is extremely important.

I recently had David install a radon system in my own house, so today I wanted to give you all an inside look at the process of testing for and mitigating radon. As David explained, radon systems like the one he installed in my home use a fan to draw out radon gas from the basement or lower levels of the home. Once the fan draws it out, the gas is expelled through an exhaust pipe.

The system also includes a disconnect box so that it can be shut off if repairs are needed. Additionally, the system runs 24/7 and lasts for years upon years. Along with catching radon, the system intercepts and exhausts out other soil gas. Since radon and other gasses leak from beneath the ground, holes like the opening around a sump pump should be caulked and sealed.

"Radon can pose a big threat to you and your family’s health, so it’s important to know how to mitigate it."
Why is it so important to mitigate radon? Radon is the breakdown of uranium, making it the gas form of radioactive material. Breathing in this gas can actually lead to lung cancer. Even so, there is no state law requiring you to test for or mitigate radon in homes. Still, it isn’t hard to understand why it’s so important.

To find out if your home has radon, you can either hire someone who performs radon testings or you can purchase a DIY test from the county. For the most accurate results, David recommends letting the test sit out over the weekend and then shipping it to a lab overnight on a Monday. Tests should be put in the lowest livable level of a home.

When you hire a professional, the equipment they use to test for radon can perform a number of functions that a DIY test can’t. When David helped me re-test my home after installing my mitigation system, the equipment he used could even detect when I had closed up the windows and doors of my house.

Closing up your home is actually very important to the accuracy of the test. You also don’t want to test during high winds or storms.

For more information, the best place to look is on the state health department’s website, which you can find here. The part of David’s business that deals with radon is Radon of Iowa. You can reach David or someone on his team at (515) 253-9100.  Here are a couple additional sites providing important information on radon:  Polk County Health Department and
