Jason Christensen with Iowa Radon Mitigation Co. installs a pipe that allows the radon trapped below the concrete to safely move to be dispersed to the outdoors, where it is less concentrated. Submitted photo.

Houses with a crawl space face the same issues as houses with a basement in terms of radon seeping into the house. Jason Christensen with Iowa Radon Mitigation Co. places thick plastic to encapsulate the walls and then pipes the radon safely out from under the house.

Jason Christensen with Iowa Radon Mitigation Co. places a fan system outside the house which connects to the pipe in the underground system, wicking the radon out of the house to a livable level.
