The average cost of radon mitigation nationally is $1,200, according to Kansas State University National Radon Program Services. Specific costs are dependent on the structure and economic conditions, which can impact overall expenses.
Costs for mitigation systems generally range from $800 to $1,500, but actual costs depend on the structure's overall size, design, foundation and climate as well as materials used to build the structure. Other expenses include operating costs, such as electricity to power fans or heating and cooling of radon drawn from the structure. Furthermore, installation of more expensive concealed mitigation systems tends to protect the aesthetic appeal of a structure, but they are more expensive than systems routed on the outside of the structure.
