Radon Free, LLC dba SWAT Environmental
Licensed ContractorLicensed under the OH radon program.
Radon Free, LLC dba SWAT Environmental is based in Milwaukee, WI but holds its radon license in OH, not in Wisconsin. Contractors licensed across a state line are common near borders and in metro areas that span one, but it is worth asking about travel and scheduling before you book.
The roster lists a single license for this business, a Radon Mitigation Contractor under number RC153. 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.
