You failed a radon test in Dubuque
Elevated readings are the expected result across Dubuque and Jackson counties, and the historic housing stock produces some of the highest numbers in eastern Iowa. High is not the same as hopeless — this is fixable work with a verifiable outcome.
Owners of historic Dubuque houses ask two things constantly: whether a stone foundation with a rough floor can be mitigated at all, and whether the old mine workings under parts of the city matter. Both have concrete answers — yes, with the right design, and the mineralized geology is part of the regional picture but not a per-address predictor.
What an elevated result actually means
Confirm the reading in the same location under closed-building conditions, which in a leaky historic house means genuinely closing it rather than assuming. If the house is in a transaction, get written quotes at the same time, and be aware that radon on a Dubuque inspection report usually shares the page with moisture, masonry, and mechanical items — deciding early what you actually want fixed prevents the radon quote from becoming a bargaining chip nobody priced. Iowa disclosure practice puts the result in front of a buyer; it does not install a system. Driftless winters are cold and the historic houses are leaky, so heating-season stack effect through a stone cellar can be dramatic. December through March gives the most conservative closed-house readings. Steep, icy bluff access genuinely affects winter scheduling for exterior work in a way it does not in flatter markets.
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 Iowa radon mitigation certification. Decide who pays, which in Iowa 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. On a cellar cut into rock, the post-mitigation test is the only proof the design reached the space — pressure readings on a manometer show the fan is pulling, not that the concentration fell. Ask for the measurement after twenty-four hours of runtime, in the original location, in writing with the Iowa certification number.
If the result landed inside a deal
Iowa sellers disclose known radon information on the state residential disclosure form; nothing requires testing or mitigation. Dubuque’s large stock of historic homes means many properties changing hands have never been tested, so the buyer’s own measurement during the inspection window is frequently the only data that exists.

Failed Radon Test questions in Dubuque
Our reading was in the twenties. Should we move out while we fix it?
Radon risk is a function of long-term exposure, and EPA frames even high readings as reasons to act promptly rather than to evacuate. A reading that high does argue for moving quickly — confirm and quote in parallel, prioritize sleeping areas when thinking about which level matters, and get the system in rather than waiting on a leisurely second measurement.
Does an elevated result put a sale in Dubuque at risk?
A tri-state corner market where buyers arrive from Illinois and Wisconsin with different expectations. Iowa disclosure practice governs an Iowa property, Iowa certification governs who may do the work for compensation, and neither compels testing or installation. The historic housing stock means radon frequently shares an inspection report with foundation, moisture, and knob-and-tube items, and it competes for negotiating attention.
Am I legally required to mitigate in Iowa?
No. A result at or above 4 pCi/L is an EPA action recommendation, not an automatic legal obligation in a Iowa 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.
