What 9.1 pCi/L means for your Earlham home
Madison County ranks 32nd of Iowa's 99 counties for average indoor radon, at 9.1 pCi/L in tests reported to the CDC from 2008 through 2017, against a U.S. average of 1.3 and an Iowa average of 8.5. Polk County, next door to the metro, averages 7.3; Madison County runs higher, and Earlham homes test accordingly. Levels vary house to house, even next door, so the only number that matters for your Earlham home is the one from a certified test in your own basement.
The county figure tells you the odds; a certified test tells you the answer. We place a continuous monitor in your Earlham 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 Earlham homes
Yes. Earlham 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 Madison 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 Madison County program contact for any assistance you qualify for.

Radon in Earlham Homes
Earlham's population has barely moved since 2010 (1,410 in the last census), which means its homes are largely the ones that were already standing: railroad-era houses from its 1870 founding onward, on stone and block foundations, plus post-war ranches with full basements. In those houses the work is sealing and suction-point placement, and we test the result before we leave.
Earlham's 0.97 square miles hold about 1,454 people per square mile, classic Iowa small-town lots with room between houses. That usually means an exterior fan on the side away from the street and a vent run that stays off the front of the house, with the neighbors far enough away that fan placement is simple.
Earlham is about 26 miles west of downtown Des Moines. Our nearest other stops are Dexter (6 mi), De Soto (7 mi) and Redfield (8 mi), so a Earlham visit usually pairs with jobs nearby. A standard test is a 48-to-72-hour continuous monitor with the report emailed the day it comes out; a mitigation is usually a single visit, with the fan on the least visible side of the house and the vent above the roofline. Every system we install in Earlham is guaranteed below 2.7 pCi/L.

Earlham Radon Questions
Is Earlham in All Midwest Radon's service area?
Yes. Earlham is 26 miles west of our Des Moines base and inside our regular service area, along with the rest of Madison County and nearby Dexter, De Soto, Redfield. We test and mitigate homes in Earlham on the same schedule as the Des Moines metro.
What is the average radon level in Madison County?
The Madison County average is 9.1 pCi/L in the CDC's 2008 to 2017 data, 32nd of 99 Iowa counties. The EPA action level is 4. Averages describe the county, not your house: Earlham homes land on both sides of the line, and only a certified test tells you which.
Can I get a free radon test kit in Earlham?
Yes. Madison 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.
How long does radon mitigation take in Earlham?
One visit for nearly every Earlham home. The crew seals a suction point in the slab or sump, runs the pipe to an exterior fan on the least visible side of the house, terminates above the roof, and sets a clearance monitor. The result is guaranteed below 2.7 pCi/L.
Do Earlham sellers have to test for radon?
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.
