When you hire a radon service provider, you should know….

Illinois regulates the radon industry. This guarantees Illinois consumers the highest quality control protections.

  • In Illinois, anyone providing radon measurement services (paid or unpaid) must be licensed by the state.
  • Only licensed radon measurement personnel can set up or pick up a test.
  • Anyone setting a measurement device outside of their own home must be licensed.
  • If your measurement provider asks you or someone else to seal a test kit and mail it back to a lab, that person is violating state law, compromising your test and our industry, and should immediately be reported to the state of Illinois.
  • When contracting for mitigation services to reduce known radon levels in a home, the contractor must be licensed by the state of Illinois to perform radon mitigation. A homeowner may attempt to mitigate his own home (which we cannot discourage enough), but if he pays someone, that person must be licensed.
  • A builder may use radon reduction techniques and devices in a pre-emptive attempt to keep radon levels low, but once a test is performed and the radon levels in the house are known, any further mitigation work must be performed by a licensed radon mitigator.

We sincerely appreciate any effort to help us keep our industry standards as high as possible. If you are concerned about a radon measurement or mitigation, please don’t hesitate to call the state radon program for guidance at 217-782-1325 or to file a non-conformance report.
