You failed a radon test in Grand Rapids
Elevated results turn up regularly across Kent and Ottawa counties, and West Michigan contractors handle them as routine work. Confirm the number, get certified bidders, and negotiate from a written quote.
West Michigan homeowners ask who is qualified, since Michigan does not license radon professionals — the answer is a current NRPP or NRSB certification. Owners of prewar houses ask whether fieldstone foundations can be sealed adequately. Lakeshore owners ask whether sandy soil means lower risk; sandy soil often moves soil gas more freely, not less.
What an elevated result actually means
Confirm in the same location under closed-building conditions, or with a ninety-day detector if you are not under a deadline. If a sale is running, confirm and quote in parallel to protect the inspection window. Michigan has no statute making mitigation compulsory at any reading, so what an elevated result creates is a negotiation and a disclosure question. A written quote from a certified contractor is what turns that conversation into a number both sides can work with. Lake-effect winters give long, reliably closed heating seasons, and December through March produces the most conservative readings. Lake-effect snow can complicate exterior work and roof access; sandy Ottawa County ground thaws and drains quickly, so spring access is less of a constraint there than in heavier soils.
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 NRPP or NRSB mitigation certification. Decide who pays, which in Michigan 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. Ask for the post-mitigation measurement after twenty-four hours of runtime, in the original detector location, in writing, with the contractor’s current NRPP or NRSB certification identified on the same page. In a state without licensing, that document and that certification are the accountability you actually hold.
If the result landed inside a deal
Michigan does not have a radon-specific disclosure statute; radon is addressed through the general Seller’s Disclosure Statement, where sellers report known conditions. Buyers should order their own test during the inspection period rather than relying on seller knowledge, and any mitigation is negotiated between the parties.

Failed Radon Test questions in Grand Rapids & West Michigan
The seller offered a credit instead of fixing it. Is that reasonable?
It is a normal outcome, provided the credit is sized to an actual written quote rather than to a guess. A credit gives you control over who does the work and which fan goes in; a seller-completed install gives you a finished system and a verification number before closing. What causes problems is a number invented at the negotiating table with no quote behind it.
Does an elevated result put a sale in Grand Rapids at risk?
A steady, growing market with strong owner-occupied demand and active new construction. Michigan does not issue a state radon license, so the credential to verify is national certification. Radon appears in inspections routinely, and elevated results are negotiated as ordinary repair items rather than treated as legal triggers, because no Michigan statute makes mitigation compulsory.
Am I legally required to mitigate in Michigan?
No. A result at or above 4 pCi/L is an EPA action recommendation, not an automatic legal obligation in a Michigan 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.
