Dyersville and Dubuque County
Dyersville routes through our Dubuque County territory with Dubuque, Farley, Epworth, and New Vienna. EPA places Dubuque County 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, which means an inspection frequently produces a home’s first-ever radon measurement. Iowa sellers disclose known radon information on the state form; where none exists, the buyer’s own test is the only data available.

Dyersville questions, answered straight
Our farmhouse has several foundation types. How is that quoted?
Zone by zone, usually on one fan. The contractor identifies every soil-contact surface — basement slab, crawl areas, slab additions — and designs suction plus membrane work so the whole footprint is addressed. Ask each bidder to name the zones.
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 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. The manometer only shows the fan is pulling. Retest every couple of years afterward.
