Sullivan and Moultrie County
Sullivan anchors our Moultrie County territory, which also routes Lovington and the Windsor area. Moultrie sits southeast of Macon County within the central-Illinois region EPA designates Zone 1 on its Map of Radon Zones — a county screening category rather than a prediction.
If the result surfaced in a transaction
Moultrie County transactions include a share of second homes and lake-area property alongside conventional village sales, and Illinois disclosure duties attach to all of them: known radon information and the state pamphlet go to the buyer. Seasonal-use properties are especially unlikely to have been tested, which puts the data burden on the buyer.

The housing you’re mitigating
Expect older homes on block and brick foundations with partial basements, plus newer construction on poured walls with sump systems. Lake-area and rural properties often have private wells, raising a separate radon-in-water question, and some seasonal cottages sit on slab or crawl foundations that still require testing despite intermittent use.

Sullivan questions, answered straight
Should a seasonal lake property be tested?
If people sleep and spend hours there, yes — exposure follows occupancy. Test under closed-house conditions during a period of normal use rather than while the place sits empty with windows open, since a test run during airing-out conditions understates what occupants actually breathe.
Our cottage sits on a crawl space. Can that be mitigated?
Yes. The standard approach seals a durable membrane over exposed crawl-space soil, seals it at walls and seams, and draws air from beneath it with a fan venting above the roofline. Crawl-space mitigation is routine licensed work; confirm the quote addresses the whole crawl area rather than part of it.
Is there a Moultrie County radon program to call?
Radon licensing and program authority in Illinois sit at the state level with IEMA-OHS. County health departments sometimes distribute test kits or awareness materials, but the contractor you hire holds a state license and the disclosure rules governing your sale are state law.
