Radon Testing & Mitigation Grinnell, Iowa

Protecting the Jewel of the Prairie and Poweshiek County

Grinnell is famous for its storied and scenic character, from the architectural masterpiece of the Merchants National Bank building to the vibrant energy of the Grinnell College campus. But while our community celebrates its rich history and coolest small town reputation, there is a modern health concern that requires attention: the high levels of indoor radon gas found throughout the region.

Poweshiek County is located in EPA Radon Zone 1, meaning the soil surrounding our homes has the highest potential in the country for elevated radon levels. At AmeriServ Radon Mitigation of Iowa, we provide the certified expertise needed to protect Grinnell’s historic treasures and modern residences alike.

Why Grinnell Homes Face Radon Challenges

The same fertile prairie soil that drew Josiah Bushnell Grinnell to found this town in 1854 also contains natural deposits of uranium. As this uranium decays, it produces radon gas that enters homes through several common pathways:

• The North Grinnell Historic District: Many of our beautiful Queen Anne and American Craftsman homes feature older foundations with specialized construction. These historic basements often have settled concrete or aging masonry that provides a direct path for radon to seep into the living space.
• Student & Faculty Housing: Whether it’s a rental near Central Park or a faculty residence near the Civic Engagement Quad, the high turnover and varied occupancy of college-town housing make consistent radon testing essential for safety.
• Rural & Recreational Properties: Homes located near Rock Creek State Park or out toward Oakland Acres often deal with unique soil moisture and pressure variations that can cause radon levels to spike unexpectedly.

Whether you are enjoying the Thursday night municipal band in the park or dining at the Periodic Table, you deserve the peace of mind that comes with knowing your home’s air is safe.

Professional Short & Long-Term Testing

Because radon levels can fluctuate with the changing Iowa seasons—especially during our windy prairie winters—we offer professional radon testing that goes beyond the basic DIY kit. Our monitors provide precise data tailored to Grinnell’s specific climate and building styles.

Custom-Designed Mitigation Systems

We understand that a home in Grinnell isn’t just a building; it’s often an architectural legacy. We design mitigation systems that are as unobtrusive as possible:

• External & Internal Venting: We strategically place suction points to pull gas from beneath the slab and vent it safely above the roofline.
• Sub-Membrane Suction: Crucial for the crawl spaces found in many of Grinnell’s older neighborhoods.
• Foundation Sealing: We use high-grade, industrial sealants to close off cracks in basement floors and walls, stopping radon at the source.
