Certified Radon Testing & Mitigation in Marshalltown, IA
Did you know that Marshall County is designated as an EPA Zone 1, the highest risk category for radon? In Marshalltown, the average indoor radon level has been recorded as high as 9.0 pCi/L—more than double the EPA’s action limit.
At AmeriServ Radon Mitigation, we don’t just provide a service; we protect your family’s health. Whether you live in a historic Italianate home in the 13th Street District or a modern build near Grimes Farm, our local specialists are here to ensure the air you breathe is clean.
Why Radon is a Priority for Marshalltown Residents
Iowa has the highest average radon concentrations in the United States, and Marshalltown is at the center of the risk. Because radon is a colorless, odorless radioactive gas produced by decaying uranium in the soil, it seeps into homes through foundations and sump pumps without any warning signs.
- Property Value: As of 2026, radon testing has become a standard expectation for Marshalltown home buyers and realtors.
- Health Impact: Radon is the leading cause of lung cancer in non-smokers and the second leading cause overall.
- The Marshalltown Reality: Local testing shows that 5 out of 7 homes in our area have elevated radon levels.
