Radon testing
Will the test follow real-estate protocols, cover the lowest occupiable area, preserve closed-house conditions, and return before the decision deadline?
Michigan Indoor Radon Program ↗Before inspection day
Do not order every add-on automatically. Use the property, utilities, disclosures, age, visible conditions, and your inspector’s stated scope to decide which unanswered questions matter before your contingency deadline.
Ask which material condition cannot be answered by the general inspection, who is qualified to answer it, what evidence they will deliver, and whether the answer can change your purchase decision.

Michigan Indoor Radon Program ↗Who owns the lateral, where is the cleanout, can the line be accessed, and will the video identify material, roots, offsets, bellies, breaks, or limited visibility?
Which water samples, flow checks, pressure-system observations, well records, and visible-condition checks are included—and who interprets the results?
Michigan Care for MiWell ↗Will the evaluator locate the tank and field, review records, inspect accessible components, describe limitations, and identify evidence of backup, surfacing, or structural failure?
Michigan SepticSmart ↗Does the inspection include the firebox, damper, visible chimney and clearances only, or is a separate camera scan or qualified chimney evaluation appropriate?
Does a crack, bow, sag, removed wall, cut framing, settlement pattern, or prior repair require a licensed design professional to identify cause and scope?
Which condition requires testing, diagnosis, repair options, remaining-life context, or a written quote from the relevant qualified specialist?
What was actually observed, what remains unknown, whether sampling is appropriate, and which credentialed specialist should define the next step?
Protect the decision window
Michigan EGLE says any home—regardless of age, efficiency, or foundation type—can have elevated radon, and testing is the only way to know. For real-estate transactions, EGLE describes special testing procedures and recommends certified professionals when an independent third party is desired.
