Certified Radon Mitigation

Licensed Contractor

Licensed under the IA radon program.

Certified Radon Mitigation is based in Sioux City, IA and licensed under the IA radon program.

The roster lists a single license for this business, a Mitigation Specialist under number RNMIT09067. One licensed professional is the norm for an owner-operator, and it does mean scheduling depends on one person's calendar.

Every license on record here is for mitigation, meaning installing the system. If you still need the house tested first, that is a separate credential and you may need a second provider.
