What 7.7 pCi/L means for your Madrid home
Boone County ranks 58th of Iowa's 99 counties for average indoor radon, at 7.7 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. That is higher than Polk County's 7.3, so a Madrid home is, on average, more likely to test high than one in the Des Moines suburbs. Levels vary house to house, even next door, so the only number that matters for your Madrid 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 Madrid 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 Madrid homes
Yes. Boone County homes qualify for a free Iowa radon test kit.
Boone County residents get one free short-term kit per household while supplies last. Start with the American Lung Association's form; depending on your address, the Lung Association may route rural Boone County homes to the Healthy Hometowns: Combat Cancer program, which covers rural Iowa, and ask you to re-order there.
Request a free kit (American Lung Association) →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.
Rural Boone County addresses that land in the Healthy Hometowns program are also in line for the program's mitigation help for homes that test high. Call us when your result comes in: we confirm it with a certified test and point you to your county's program contact.

Radon in Madrid Homes
Home to 2,802 people and growing at 10% a decade, Madrid pairs an older turn-of-the-century town center with newer construction on its edges. Older homes here often have block walls and sometimes a crawl space; the newer ones have poured basements and sump pits. We size the system to the foundation, not the town.
Packing 2,802 people into 1.19 square miles, Madrid has tighter lots than most of Boone County. On a narrow lot the exterior fan and the vent need to clear the neighbor's openings and the house's own windows, which we plan before we drill.
Madrid is about 22 miles northwest of downtown Des Moines. Our nearest other stops are Woodward (5 mi), Slater (7 mi) and Polk City (8 mi), so a Madrid 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 Madrid is guaranteed below 2.7 pCi/L.

Madrid Radon Questions
Is Madrid in All Midwest Radon's service area?
We do. Our Boone County route covers Madrid and its neighbors Woodward, Slater, Polk City, 22 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 Madrid?
7.7 pCi/L, based on tests reported to the CDC Tracking Network from 2008 through 2017. That ranks 58th of Iowa's 99 counties and is 1.9 times the EPA action level of 4 pCi/L. Individual Madrid 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 Madrid?
Yes. Boone County households can request one free short-term radon test kit through the Iowa HHS and American Lung Association free kit program, while supplies last. Rural addresses may be routed to the Healthy Hometowns: Combat Cancer program instead. 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 Madrid involve?
Most Madrid 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 Madrid?
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, and with Madrid adding homes as fast as it has, that is a test we run often. We schedule those seven days a week.
