Clean Air Radon Systems is based in Plainfield, IL and licensed under the IL radon program.
The roster lists a single license for this business, a Mitigation Professional under number RNM2017208. 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.
