Radon mitigation in Le Mars, Iowa
Radon testing and systems for Le Mars and the rest of Plymouth County, northeast of Sioux City along the Floyd River.
Le Mars is the county seat of Plymouth County and had 10,571 residents at the 2020 census. It sits on the Floyd River northeast of Sioux City and calls itself the Ice Cream Capital of the World, thanks to Wells Enterprises' large novelty plant. The town grew after the railroad arrived in 1870, so it has a solid stock of older homes along with newer houses on the edges.
Older homes and farmhouses
Older Le Mars homes and farmhouses in the county often have stone or block basements, partial basements with crawl spaces, and generations of additions. Those foundations can have many openings for soil gas and may need extra sealing or more than one suction point.
What radon work comes up in Le Mars?
- Sub-slab systems in older basements
- Membrane systems for crawl space sections and additions
- Testing for home sales
- Activating passive radon pipes in newer homes that still test high
Credential check
Le Mars is in Iowa, so anyone mitigating radon for pay needs an Iowa HHS credential, and paid testers need Iowa certification. Ask for the number before work starts, and keep the post-mitigation test result with your house records.
