You failed a radon test in the Omaha metro
An elevated reading in the Omaha metro is common enough that contractors here see it constantly. The number describes a fixable building condition, and the useful next move is confirming it while collecting written quotes.
The most common local questions are about newer houses: whether a builder-installed passive stack counts as mitigation, and whether a walkout basement is somehow lower risk. Neither is true — a passive stack needs a fan and a verified reading, and a walkout still has a slab and buried walls in contact with soil. Bistate buyers also ask which state’s rules apply.
What an elevated result actually means
Confirm in the same spot under closed-building conditions, walkout door included. If you are under contract, run confirmation and quoting simultaneously so the inspection window does not expire. In the newer subdivisions, check the attic for a passive stack before either side takes a position — the fix may be inexpensive enough to end the negotiation immediately. Nebraska practice centers on credentialing for paid work and on ordinary disclosure obligations; it does not compel a seller to install a system at any reading. Closed-house conditions from December through March give the most conservative readings, and stack effect through a full basement in a Nebraska winter is strong. Spring is the busiest inspection season, and open windows during a showing week are the most common reason a short-term test produces a number nobody should rely on.
Your next four steps
Four steps, in this order. Confirm the result — a second short-term test or a longer-term measurement, run under closed-building conditions. Get written quotes from independent businesses holding a current Nebraska radon mitigation credential. Decide who pays, which in Nebraska is a negotiation and not a legal mandate. Then verify with a post-mitigation test after the system runs. Nothing about a single elevated reading forces you out of your house or out of a contract. The number after the work is the only thing that settles whether the work succeeded. Require it on paper, carrying the Nebraska credential, taken where the first detector sat and after the fan has run a full day. Builder-installed stacks make this especially worth insisting on: they are built to a construction standard rather than to your measured conditions, and a few of them underperform the moment a fan is applied.
If the result landed inside a deal
Nebraska has moved to require radon-resistant construction techniques in new residential construction, and radon is a routine inspection item in metro transactions. Nebraska does not require a seller to test or to mitigate an existing home — the response to an elevated result is negotiated. Confirm current requirements with the state radon program, since new-construction rules have changed in recent years.

Failed Radon Test questions in Omaha Metro
We are buying in Council Bluffs instead. Do the same rules apply?
No. Council Bluffs is in Iowa, and an Iowa property is governed by Iowa disclosure practice and Iowa certification for paid measurement and mitigation. A Nebraska credential does not carry across the river and vice versa. In a metro that spans a state line, confirm which state the property is in before assuming which rules and which credential apply.
Does an elevated result put a sale in the Omaha metro at risk?
A high-volume metro market that spans a state line at Council Bluffs, so buyers and agents routinely carry expectations across. Nebraska credentials radon measurement and mitigation businesses through its state health and human services department, and that credential is what governs paid work on a Nebraska property regardless of where a firm is based.
Am I legally required to mitigate in Nebraska?
No. A result at or above 4 pCi/L is an EPA action recommendation, not an automatic legal obligation in a Nebraska sale. What state law generally governs is disclosure — telling a buyer what you know — not whether a system gets installed. Who pays, and whether the work happens before closing, is negotiated between buyer and seller.
