If the result surfaced in a transaction
Transactions here often involve long-held family property, which means inspection findings frequently surface facts nobody had measured. Iowa sellers disclose known radon information on the state form; nothing requires a seller to fix an elevated result.

The housing you’re mitigating
The older core brings brick and block foundations with partial basements and crawl areas beneath additions or porches. Postwar blocks are ranch-dominated with sump pits common. Surrounding farm properties bring mixed-foundation farmhouses and private wells raising a separate water question.

Charles City questions, answered straight
Can sealing alone fix an elevated result?
Not reliably. EPA treats sealing as a supplement rather than a standalone fix — you can never find every entry path, and the pressure difference pulling soil gas in remains. Active sub-slab depressurization addresses the physics.
How long does a mitigation system last?
The piping and sealing are effectively permanent; the fan is the wear item. Radon fans commonly run many years of continuous duty before needing replacement, which is a routine service call. Watch the manometer occasionally.
Is there a county radon office in Floyd County?
Radon certification and program authority in Iowa sit at the state level with the health department. County health departments sometimes distribute test kits, but the professional you hire holds a state certification.
