Frequently asked questions
- How often should a Minnesota home be tested?
- MDH recommends testing every two to five years, after any major renovation, after you change how you use a lower level (like finishing a basement), and after any mitigation work to confirm it performs. Winter, with the house closed up, is the best testing season.
- Does home age or foundation type change the risk?
- Any home can have high radon: old or new, with or without a basement. Newer homes are not automatically safer, and homes built with passive radon-resistant features still need a test to confirm those features work. That is why the checkup treats these as context, not as a pass.
- What does Minnesota law require when a home is sold?
- The Minnesota Radon Awareness Act (Minnesota Statutes section 144.496) requires sellers to disclose in writing what they know about radon in the home, including any past test results and any mitigation system, and to give buyers the state's radon warning statement and an MDH publication before the purchase agreement is signed. It does not require testing or mitigation, which is exactly why buyers usually test during the inspection period.
- Are my answers stored anywhere?
- No. The checkup runs entirely in your browser and your answers are never sent to us. If you choose to sign up for a retest reminder or request quotes at the end, only what you type into that form is transmitted, after you affirmatively agree.
