Le Mars and Plymouth County
Le Mars anchors our Plymouth County territory, which also routes Hinton, Merrill, and Remsen. EPA places Plymouth County — like all of Iowa — in Zone 1 on its Map of Radon Zones. Iowa certifies radon measurement and mitigation specialists through the state health department.
If the result surfaced in a transaction
Transactions here often involve long-held family property, so an inspection frequently produces a home’s first-ever radon measurement. Iowa sellers disclose known radon information on the state form; nothing requires a seller to fix an elevated result.

Le Mars questions, answered straight
Our farmhouse has several foundation types. How is it quoted?
Zone by zone, usually on one fan. The contractor identifies every soil-contact surface and designs suction plus membrane work so the whole footprint is addressed. Ask each bidder to name the zones.
We are on a private well. Two tests?
Potentially. The airborne test covers the house; a separate water test tells you whether radon is arriving dissolved in well water. Fix the air first, then let the water result decide.
How do we verify the system worked?
Insist the post-mitigation radon test be in the scope of work. Run under closed-house conditions after startup, it proves the indoor number dropped rather than merely that the fan is running.
