How this site works
Rockford Radon Guide is an independent website run by one operator. It explains radon testing and mitigation for Rockford-area homeowners and answers questions.
What we are
- An independent information site with sourced facts and links to official Illinois and U.S. EPA material.
- A way to ask questions. Your message reaches the site operator only.
What we are not
- We do not perform radon testing or mitigation, sell test kits, or give engineering advice.
- We are not a licensed radon contractor. In Illinois, testing and mitigation must be done by IEMA-OHS-licensed professionals.[1]
- We are not affiliated with IEMA-OHS, the Winnebago County Health Department, or any radon company.
Partners and money
Right now, this site has no partner companies and receives no payment from any radon business. In the future, the site may feature an IEMA-OHS-licensed company as a paid advertiser. If that happens:
- the company will be named on the site under its licensed name, with its IEMA-OHS license number and a link to the state lookup;
- any payment will be a flat advertising fee, not a commission on your job; and
- your details will only be passed to that company if you are told its name and agree.
Verify, don't trust
Whoever you hire, check their license in the IEMA-OHS licensee lookup, get written estimates, and arrange an independent follow-up test after mitigation.[2]
