Radon Testing and Mitigation in Emmetsburg, IA
Midwest Radon Pros is part of Midwest Companies, and our shop is in Spirit Lake, about forty-five minutes northwest of Emmetsburg. 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, Palo Alto 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 Emmetsburg. Every mitigation job ends with a post test, so the work comes with a number instead of a handshake.

The Youngest Ground in Iowa
Palo Alto County has towns called Mallard, Plover, and Curlew. The Iowa Geological Survey points at those names as a record of what this country looked like before it was drained, when the wetlands here drew enormous flocks of waterfowl. That is the prairie pothole landscape, and it exists because the ice left recently enough that the drainage never had time to sort itself out.
This is the youngest landscape in the state, and Emmetsburg sits in the middle of it. The Des Moines Lobe melted off about twelve thousand years ago and left behind pebbly till, sand and gravel, and a surface full of shallow depressions with nowhere to send their water. Most of those potholes were tiled and ditched for farming generations ago, but the ground underneath is the same ground.
One difference matters for anyone comparing notes with family over in Le Mars or Sheldon. Out west, the glacial material is buried under a blanket of wind-blown loess. Here there is essentially none. The till is right there, directly under your foundation, without an intervening layer of anything.
For radon that is a distinction without a difference. Glacial till is pulverized rock, trace uranium in it decays into radium, radium decays into radon, and the gas moves up through the soil until a heated building acts like a low grade vacuum and draws 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.
What the Number Actually Means
Everybody in this trade tells you to test and to fix what you find. Almost nobody explains how to weigh the result once you have it, so here it is plainly.
Radon causes lung cancer, and the EPA calls it the leading cause among people who have never smoked. The EPA attributes roughly 21,000 lung cancer deaths a year in the United States to radon, and Iowa sources put the state’s share at somewhere around 400. Those are real numbers and they are why any of this exists.
The risk is not the same for everyone. Radon and smoking together are far more dangerous than either one alone. If somebody in the house smokes, or used to, a given radon level carries considerably more risk than the same level in a household where nobody ever has. That is not a reason to skip testing if nobody smokes. It is a reason to move faster if somebody does.
Four is a threshold, not a cliff. The action level is where the EPA says to fix it, not where the danger switches on. Risk rises with the level and with the number of years of exposure, which is why a 5 is worth doing something about and why a 20 is worth doing something about sooner. It is also why the EPA suggests considering mitigation between 2 and 4.
Time is the other half of the equation. This is exposure measured in years, not in days. That is what makes a high result a serious thing to handle rather than an emergency to panic about, and it is also why putting it off for another five years is the actual mistake.
None of that tells you what to do about your particular house. A number does.
Our Radon Services.
Radon Services in Emmetsburg, 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 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. We replace fans, repair piping, and bring 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. 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.
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. Call and we will talk through what to expect, but the number itself comes when we are standing in the building.
Why Emmetsburg 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. We are about forty-five minutes out, so a test means two trips for us, which makes the first call the right time to mention a deadline. 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 north of here in Estherville and west in Spencer.
Being local changes how fast things move. Our shop is in town, so the drive is short and scheduling is easy. Midwest Radon Pros is part of Midwest Companies, so if radon work turns into an insulation, crawl space, or Guarantee Gutter question, the same local operation handles it.Drain Tile and Sump Pits
A landscape that never developed drainage on its own ends up with drainage built into it. Around Emmetsburg that means tile in the fields and, in a great many buildings, drain tile and a sump pit under the basement floor.
For radon that cuts both ways. An open sump pit is a wide, direct opening between the soil and the room you are standing in, and it is one of the most common entry points we find. It is also, once it is sealed with a gasketed lid, one of the best places to draw from. A system that pulls through existing drain tile often works better than one cored through the middle of a slab, and it is usually a cleaner install. If your basement has a pit with a loose cover or no cover, that is worth a look regardless of what your test says.
Common Radon Calls Around Emmetsburg
A basement gets finished into a bedroom and somebody thinks to ask about the air. An inspection comes back high three weeks before closing. Somebody who quit smoking years ago starts thinking harder about the number on an old test. A sump pit sits open under a finished basement stairway. A system from years back has a manometer nobody has checked. All routine.

Frequently Asked Questions.
Questions Emmetsburg Homeowners Ask About Radon
How bad is a 6, really?
It is above the action level, so the short answer is that it should get fixed, and the qualifier is that you have time to do it properly rather than in a panic. Radon risk builds with the level and with the years of exposure, so a 6 is a real thing to address and not a reason to leave the house. Where it sits on your personal list depends on who lives there, how much time they spend on the lowest floor, and whether anybody in the household smokes or used to.
Nobody in our house smokes. Does that change anything?
Does it matter how long we have lived here?
Yes, because exposure adds up over years. That is not a reason to feel bad about a house you have been in for twenty years. Nothing about fixing it now is wasted, since the exposure that matters most is the exposure you have not had yet. It is a reason not to wait another twenty.
Why is the ground here different from Le Mars or Sheldon?
No loess. Out in the northwest corner of the state, the glacial material is buried under a blanket of wind-blown silt, several feet of it in places. On the Des Moines Lobe there is essentially none, so the till sits directly beneath your foundation. It is also much younger ground, about twelve thousand years since the ice melted off, which is why this country has potholes and lakes and the western counties do not. None of that predicts your radon level. It just explains what is down there.
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. Put the date in the first call so we can build the schedule around it.
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.
