Radon Testing and Mitigation in Milford, IA
Midwest Radon Pros is part of Midwest Companies, and our shop is on Aurora Avenue West in Spirit Lake, about fifteen minutes up Highway 71 from Milford. Radon gives no warning. You cannot see it or smell it, and the only way to know what a house is doing with it is to put a meter on it. Dickinson County sits in the EPA’s highest risk zone, and that does not stop at the shoreline.
We handle State of Iowa credentialed radon testing, mitigation installs, fan replacements, repairs, new construction systems, and real estate testing for homes and buildings in Milford. Every mitigation job ends with a post test, so the work comes with a number instead of a handshake.

Radon Is Not a Lake Problem
People around here sometimes assume radon belongs to the lakeshore, the way ice dams and dock work do. It does not. Radon comes out of the ground, and the ground under Milford is the same glacial drift that sits under every town in this county.
Drive four and a half miles northwest of town and you can walk to the edge of the proof. Freda Haffner Kettlehole State Preserve holds the largest glacial kettlehole in Iowa, a steep-sided bowl left behind when a buried block of ice melted in place roughly 13,000 years ago. The Des Moines Lobe put that ice there, and it put the drift under your house at the same time. Glacial till is rock the ice ground to powder, trace uranium in it decays into radium, radium decays into radon, and the gas works up through the soil until a heated building gives it somewhere to go.
Milford sits a little higher than the lakes and a few miles inland, and that changes the drainage and the views. It does not change the source. Iowa HHS lists the average indoor radon level in Iowa at 8.5 pCi/L against a national average of 1.3, and the Iowa Radon Survey put 71.6 percent of Iowa homes above the EPA action level of 4 pCi/L, the highest share in the country. Compiled test data for Dickinson County puts the county average at 8.3 pCi/L. If anything, an ordinary house on an ordinary Milford lot is the situation those numbers describe best.
Our Radon Services.
Radon Services in Milford, IA
The calls come in a few shapes. A house has never been tested. A result came back high. A fan that ran for years has gone quiet. A closing is coming and radon is part of the deal.
Radon Testing
A continuous monitor goes on the lowest livable level and runs at least 48 hours under closed house conditions. It records hour by hour instead of handing back one averaged figure, and that record also shows whether the house stayed closed while the test ran. You get the result in plain language and a straight answer about what it means. Learn more about radon testing.
Radon Mitigation
At 4 pCi/L or higher, the fix is a sub slab depressurization system. A pipe reaches through the slab into the soil below, a fan holds steady suction under the foundation, and the gas vents above the roofline instead of collecting in the basement. Most installs are finished in a day, and every one ends with a post test that proves the level came down. See how radon mitigation works.
Fan Replacement and System Repair
Radon fans last five to ten years, so plenty of systems in town are due or past due. When a fan quits, the system quits with it, silently. The manometer is the first check. If the liquid in the two legs has leveled out, nothing is being pulled. We replace fans, repair piping, and bring existing systems back to work.
New Construction Radon Systems
As of July 1, 2026, Iowa building code requires a passive radon system in new single and two family homes. Milford has been adding houses steadily, and roughing a system in while the foundation is open costs a fraction of retrofitting it later. A passive stub does not always get the level low enough on its own, so test the finished house and add a fan if the number calls for one.
Real Estate Radon Testing
Iowa sellers must disclose known radon test results, and buyers here increasingly write testing into the offer. We test with equipment and protocols that hold up on both sides of the closing table, and we schedule against the closing date, because closing dates do not move for anyone.
What to Expect From a Radon Test or Install
Call or request a quote, and we sort out the building type, the test type, and the calendar. The monitor goes on the lowest livable level and we explain what closed house conditions mean. The house stays closed for the test window, then we pull the data and send the result. If mitigation is called for, we quote it, schedule it, and close it out with a post test. On a repair, we check the fan, the manometer, the piping, and the vent line first.
Pricing and Estimates
Radon work gets priced after we see the building. The foundation, the sump pit, the fan placement, and how many suction points it takes all move the number. Call and we will talk through what to expect, but the number itself comes when we are standing in the house.
hy Milford Property Owners Choose Midwest Radon Pros
Iowa requires anyone paid to install a radon reduction system to be credentialed through the state. Our installers are, and we show the credential without being asked. Past the credential, what matters is proof. A system that looks right and pulls nothing is worse than no system, because it feels solved. That is why every install ends with a post test.
Being close also matters more than it sounds. A monitor gets set and picked up without half a day of driving on either end, which keeps jobs moving. Midwest Radon Pros is part of Midwest Companies, so when radon work runs into a crawl space, insulation, or Guarantee Gutter question, the same local operation handles it. We do the same work in Arnolds Park and Spirit Lake.
Full Basements and Full-Time Living
Milford is a year-round town, and that is the part that matters most for radon. These are families in houses they occupy every day of the year, not places that get opened in May and closed in September.
Radon risk is a matter of dose over time, so the exposure that counts is the one that happens daily. A Milford basement is usually a full basement, meaning all four walls and the floor are in contact with soil rather than one wall open to a slope. That is more surface for gas to find its way through, and the space below grade tends to be the rec room, the laundry, the home office, and often a bedroom. Winter makes it worse, because a sealed, heated house in January exchanges far less air than the same house in June while the furnace pulls harder on the soil underneath it.
Schools, Preschools, and Daycares
Milford has public schools and licensed childcare centers, and the state has put a clock on radon for both. Under Iowa Code 280.32, the Gail Orcutt Radon School Safety Act, every public school attendance center has to be tested at least once by July 1, 2027, and every five years after that, with results posted on the district’s website. Testing has to be done by an Iowa certified radon measurement specialist or by district staff who have completed an approved training program. If a first test comes back at or above 4 pCi/L, a second test has to run within sixty days, and if the two tests average at or above 4 pCi/L, a mitigation plan is due within two years of the first test.
Licensed childcare centers have their own rule. Under Iowa Administrative Code 441-109, a center must test for radon within a year of being licensed, and the requirement applies again when the license is renewed. If you run a center or a preschool in Milford and you are not sure where you stand, call and we will walk through it with you.
Common Radon Calls Around Milford
A family finishes the basement into a bedroom and a rec room and then wonders what is in the air down there. An inspection comes back at 10 pCi/L two weeks before closing. A system from the early 2000s has a manometer that has leveled out. A new build has a capped pipe in the slab and the owner has no idea whether it does anything. A daycare director gets asked for a test result she has never seen. All routine, and all of them start with a number.

Frequently Asked Questions.
Questions Milford Homeowners Ask About Radon
We are not on the lake. Is radon less of a problem out here?
No. Radon comes out of soil, not water, and the glacial drift under Milford is the same material that sits under the lake towns. Being inland changes your view and your drainage. It does not change what is decaying in the ground beneath your basement. Every county in Iowa is in the EPA’s highest risk zone, Milford included.
When should we test, and does the season matter?
Any time of year gives you useful information, and heating season gives you the most conservative number. A closed, heated house in January exchanges less air and pulls harder on the soil below it, so levels usually run higher then than they do in June. If a summer test lands anywhere near 4 pCi/L, it is worth repeating in the cold months before deciding anything.
Is a full basement worse than a walkout?
Usually, though not always. A full basement has all four walls and the floor against soil, so there is more contact area and more opportunity for gas to enter through cracks, the sump pit, floor drains, and gaps around plumbing. A walkout has one wall open to the outside and the rest still buried. Neither one is safe or unsafe by design. The only thing that settles it is a test.
Our school or daycare has to test. What does that involve?
For public school attendance centers, Iowa Code 280.32 requires testing at least once by July 1, 2027 and every five years after, done by a certified measurement specialist or trained district staff, with results posted publicly. If a first test comes back at or above 4 pCi/L, a second test runs within sixty days, and if the two tests average at or above 4 pCi/L, a mitigation plan is due within two years of the first test. Licensed childcare centers test within a year of being licensed under a separate rule. Larger buildings follow different measurement protocols than a single family house, so tell us the building and we will tell you what it takes.
Can you work around a closing date?
Yes, and we do it often. Give us the date on the first call. A 48 hour test plus results, and if mitigation is needed a one day install with a verification test 24 hours after the fan starts, fits inside most inspection periods when it is scheduled early rather than in the last week.
I already have a system. How do I know it is still working?
Look at the manometer on the pipe, the small gauge with colored liquid in a U shape. If the two sides have leveled out, the fan has quit. Even when it shows suction, the only proof of the actual radon level is a test, which is why the EPA recommends retesting every two years, mitigated homes included.
