Radon Testing and Mitigation in Ida Grove, IA
Midwest Radon Pros is part of Midwest Companies. Our shop is in Spirit Lake, roughly ninety miles north of Ida Grove by road, and we will be straight with you about what that means further down this page. Radon gives no warning. You cannot see it or smell it, and the only way to know what a building is doing with it is to put a meter on it. Every county in Iowa sits in the EPA’s highest risk zone, Ida County included.
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 Ida Grove. Every mitigation job ends with a post test, so the work comes with a number instead of a handshake.

A Castle Does Not Keep Radon Out
Ida Grove calls itself Castletown, and it earned the name. Starting in the late 1960s, Byron Godbersen, who founded Midwest Industries here in 1954, began putting castellated towers on buildings around town: a hangar in 1967, the city marker tower in 1971, the convention center in 1974, and a skating rink that looks like a fortress. Plenty of people in the lakes country own a piece of his work without knowing it. Midwest Industries builds ShoreStation boat lifts, and Godbersen designed the first one in 1959.
The castles make a useful point. What a building looks like tells you nothing about what it is doing with soil gas. Stone walls, heavy block, a solid-looking foundation: none of it is a barrier. Radon moves through the smallest openings a building has, the joint where the floor meets the wall, the gap around a pipe, a crack you would need a flashlight to find. A fortress built on the ground is exactly as exposed at the ground as a ranch house next door.
The ground itself is ordinary for this corner of Iowa. Old glacial till sits under a mantle of wind-blown loess, and the Maple River has cut its valley down through it, which is why Ida Grove has real grade. All of that material is pulverized rock. Trace uranium in it decays into radium, radium decays into radon, and the gas works up through the soil until a heated building acts like a low grade vacuum and pulls it in through slab cracks, sump pits, floor drains, and gaps around plumbing.
Iowa HHS puts the average indoor radon level in Iowa at 8.5 pCi/L against a national average of 1.3, and the Iowa Radon Survey found 71.6 percent of Iowa homes above the EPA action level of 4 pCi/L, the highest share of any state. Those are state numbers. They tell you to test. They do not tell you about your building.
Businesses, Churches, and Public Buildings
Ida Grove is a manufacturing town and a county seat, which means a lot of people spend their working day in buildings nobody has ever tested. Offices, shops, churches, clinics, and the lower levels of buildings downtown all sit on the same ground as the houses around them.
Most of them are not required to test. Iowa requires radon testing in public school attendance centers and licensed childcare centers. It does not require testing in private businesses, offices, churches, or most other commercial buildings. We are not going to tell you otherwise.
The case for testing anyway is simple. People spend eight or nine hours a day at work, five days a week, for years. If the workspace is on the lowest level of a building, that is a real share of somebody’s exposure, and it is exposure the owner of the building controls.
Larger buildings are tested differently from houses. A single family home gets one monitor on the lowest livable level. A commercial building with several rooms in ground contact generally needs a device in each of them, because rooms on the same slab do not all read alike. The number of devices depends on the floor plan, which is why we want to see the building before quoting the test.
Hourly data matters more at work. A continuous monitor shows what the building did during the hours people were in it, not just an average that includes nights and weekends when the air handling may run differently.
Mitigation is the same principle at a larger scale. Sub slab depressurization works under a commercial slab the same way it works under a house, though a large floor may need more than one suction point. If a building tests high, we will tell you what it takes before anybody commits to anything.
Our Radon Services.
Radon Services in Ida Grove, IA
The calls come in a few shapes. A building 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 building 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 into the soil under the foundation, a fan holds steady suction there, and the gas vents above the roofline instead of collecting in the basement. Most residential 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 an older system may be 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. Given the drive, we would much rather fix what you have than sell you something new.
New Construction Radon Systems
As of July 1, 2026, Iowa building code requires a passive radon system in new single and two family homes. Roughing one in while the foundation is open costs a fraction of retrofitting it later. A passive system lowers radon but does not guarantee a level, so test the finished house and add a fan if the number calls for one.
Real Estate Radon Testing
Iowa has no rule requiring a radon test during a sale, but sellers must disclose known test results, and buyers increasingly ask for a test anyway. We test with equipment and protocols that hold up on both sides of the closing table. Tell us the closing date on the first call.
How the Schedule Works From Here
Ida Grove is at the far edge of where we work, and there is no dressing that up. A test takes two visits, one to set the monitor and one to collect it, so a single address is two round trips. What makes it workable is that Ida Grove sits close to Sac City and within reach of Storm Lake, and we run work in that corner of the state in batches rather than one address at a time.
For you that means calling earlier than you would call a contractor in town, and putting any deadline in the first call. It also means that if you have more than one building, a neighbor who has been meaning to test, or a business and a house, one trip can cover all of it and it costs less per building. If somebody closer will show you a state credential and include a post installation test, hire them. That is a better outcome than waiting on us.
What to Expect From a Radon Test or Install
Call or request a quote, and we sort out the building, the test, and the calendar. The monitor goes on the lowest livable level and we explain what keeping the building closed means. You keep it closed for the test window. We come back for the monitor, pull the data, and send the result. If mitigation is needed, we quote it, schedule it, and finish with a post test.
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, and on a commercial building so does the floor plan. Call and we will talk through what to expect, but the number itself comes when we are standing in the building.
Why Ida Grove 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. Ask us for it, and ask anybody else you call for it too.
Past the credential, what matters is proof. A system can look finished and pull nothing, and that is worse than no system at all, because it feels solved. That is why every install ends with a post test. Midwest Radon Pros is part of Midwest Companies, so when radon work runs into a crawl space, insulation, or Guarantee Gutter question, the same operation handles it. We do the same work in Sac City and Cherokee.
Houses in the Maple River Valley
The Maple River gives Ida Grove more grade than most towns its size, and that changes the job. A house stepped into a slope often has a lower level with one wall exposed and the rest buried, sometimes with a second slab at a different elevation under an addition. More than one kind of ground contact can mean more than one suction point, and which side of the house is uphill decides where the pipe can run and discharge. None of that makes a house hard to fix. It means the design is worth working out on site.
The older housing stock follows the usual pattern for an older county seat: block and poured basements of every era, additions on slabs, and basements finished at some point along the way. If your place has been remodeled or tightened up since its last test, test again.
Common Radon Calls Around Ida Grove
A business owner wants to know whether the lower-level offices have ever been tested. A basement gets finished into a bedroom and somebody thinks to ask about the air. An inspection comes back high three weeks before closing. A church wants to test its fellowship hall. A system from years back has a manometer nobody has checked. All routine.

Frequently Asked Questions.
Questions Ida Grove Owners Ask About Radon
Does a stone or heavy block building keep radon out?
No. Radon does not need to get through the wall. It comes in where the building touches the ground: the joint between floor and wall, gaps around pipes, slab cracks, an open sump. A heavy building is as exposed at those points as a light one. Only a test tells you the level.
Does my business have to test for radon?
Not under Iowa law, unless it is a public school attendance center or a licensed childcare center, both of which have their own testing requirements. Private businesses, offices, and churches are not required to test. The reason to do it anyway is that employees spend a large share of their week there, and if the workspace is on the lowest level of the building, that exposure is under the building owner’s control.
What does testing a commercial building involve?
More devices than a house, and a little more planning. Rooms in ground contact generally each get their own device, because rooms on the same slab do not all test alike. The test still runs under closed building conditions, and we look at the floor plan first so the test is sized to the building.
Ida Grove is a long way from Spirit Lake. Is it worth calling you?
It is worth asking, and it is worth asking anybody closer the same questions. What you are paying for is the state credential and a post installation test that proves the system works. If a closer contractor offers both, that is a fine choice. If you call us, we will batch your job with other work in this part of the state and give you a specific date rather than a vague promise.
Can you work around a closing date?
Usually, if you call early. 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. At this distance our schedule is the limiting factor rather than the work, so put the date in the first call.
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, only a test proves the radon level actually came down, which is why the EPA recommends retesting every two years, mitigated homes included.
