What 11.8 pCi/L means for your Sully home
In the CDC's 2008 to 2017 data, the average Jasper County home measured 11.8 pCi/L before mitigation, 5th highest of Iowa's 99 counties and far above the U.S. average of 1.3. That is higher than Polk County's 7.3, so a Sully home is, on average, more likely to test high than one in the Des Moines suburbs. Iowa HHS is blunt that neighbors can test very differently, which is why we never guess at a Sully home from the county figure.
The county figure tells you the odds; a certified test tells you the answer. We place a continuous monitor in your Sully home for 48 to 72 hours and email the report the day it comes out. If it reads 4 pCi/L or higher, you get a written mitigation quote the same day, and every system we install is guaranteed below 2.7 pCi/L.
Free radon test kit for Sully homes
Yes. Sully is in a rural Iowa county covered by the state's free radon test kit program.
Healthy Hometowns: Combat Cancer, run by Marion County Public Health with local health departments across rural Iowa, provides one free radon test kit per household while supplies last. Request it through the program's order form, or ask Jasper County Public Health.
Request a free kit (Healthy Hometowns: Combat Cancer) →A free kit is a mailed charcoal test: results take a couple of weeks, one kit can miss a high reading, and it is not accepted for a real-estate sale. If it comes back at 4.0 pCi/L or higher, the next step is a certified 48-to-72-hour monitor test with same-day results, then a same-day mitigation quote.
The same program is funding mitigation help for rural homeowners whose homes test high. If your kit comes back at 4.0 pCi/L or above, call us: we confirm the number with a certified monitor test, quote a system the same day, and point you to your Jasper County program contact for any assistance you qualify for.

Radon in Sully Homes
Sully has held close to 881 residents for the last decade, and most of its housing dates from well before the era of poured basements and drain tile. Incorporated in 1901, its turn-of-the-century homes tend to sit on concrete-block or stone foundations, often with a partial basement or crawl space, which gives radon more than one way in.
With about 1,519 residents per square mile over 0.58 square miles, Sully has the lot sizes of a traditional Iowa town: detached houses, side yards, and room to put the fan and vent where they are least visible. Routing is rarely the hard part here; the foundation is.
We reach Sully, 40 miles east of Des Moines, a routine drive for our crews, on regular routes. Lynnville (3 mi), Kellogg (10 mi) and Newton (13 mi) are the neighboring towns on the same route. Testing is a 48-to-72-hour continuous monitor with same-day results, and most mitigations finish in one visit, followed by a clearance test and our 2.7 pCi/L guarantee.

Sully Radon Questions
Is Sully in All Midwest Radon's service area?
We do. Our Jasper County route covers Sully and its neighbors Lynnville, Kellogg, Newton, 40 miles out from Des Moines. Tests are scheduled seven days a week and mitigation visits are booked like any metro job.
How high is radon around Sully?
11.8 pCi/L, based on tests reported to the CDC Tracking Network from 2008 through 2017. That ranks 5th of Iowa's 99 counties and is 3.0 times the EPA action level of 4 pCi/L. Individual Sully homes test both far above and below that average, which is why a test of your own home is the only reliable answer.
Can I get a free radon test kit in Sully?
Yes. Jasper County households can request one free short-term radon test kit through Healthy Hometowns: Combat Cancer, the state program for rural Iowa, while supplies last. A kit is a good first look, but results take weeks and it is not accepted for a home sale. A certified 48-to-72-hour monitor test gives same-day results, and any reading at 4.0 pCi/L or above should be confirmed that way before mitigation.
What does a mitigation install in Sully involve?
Most Sully installs are completed in a single visit. We place a sealed suction point in the slab or sump pit, route the vent pipe to an exterior fan, and finish above the roofline, then run a post-mitigation clearance test. Every system is guaranteed to bring the home below 2.7 pCi/L.
Is a radon test required to sell a home in Sully?
No. Iowa Code chapter 558A is a disclosure law: a seller must disclose any known test results and provide the Iowa Radon Home Buyers and Sellers Fact Sheet, but no law requires the test itself. In practice the buyer orders a certified test during the inspection period. We schedule those seven days a week.
