Real Estate Radon Testing in Minneapolis, MN

What the Radon Awareness Act Changed

Since 2014, Minnesota sellers of residential property have had to disclose in writing what they know about radon before a purchase agreement is signed: whether the house has been tested, the most recent results and reports, any mitigation system with its description and documentation, a radon warning statement, and a copy of the Health Department's booklet “Radon in Real Estate Transactions.” The law does not require a seller to test. It does mean a test result, once it exists, becomes part of the disclosure.

For Buyers: Testing Inside the Inspection Period

Most buyers meet radon during the inspection period, with a contingency date that decides how much leverage they have. That is what shapes the job. The measurement is the same 48 hours it always is, but the scheduling has to leave room for the result, a conversation with your agent and — if it is high — a mitigation quote before the deadline. Tell us the date when you call and we will tell you straight away whether we can make it.

For Sellers: Knowing Before the Buyer Does

Testing before you list means any high reading shows up on your schedule rather than halfway through a buyer's inspection period. A mitigated house with a documented low retest is usually treated as a solved problem. An unexpected high number with days left on a contingency is where sellers lose money. Ask your agent how a pre-listing test fits your disclosure — the law is about what you know, and they will know how to handle it.

Test Conditions During Showings

A house on the market is opened and closed constantly, which is the opposite of closed-house conditions. A defensible test needs everyone involved — agents, sellers, anyone showing the house — to know it is running. We use continuous monitors that record tampering and sudden changes, and the report states the conditions it was measured under.

Houses That Already Have a System

A disclosed system still deserves a test. Fans fail without any sign in the house, and a post-2009 passive pipe may never have been checked at all. A short retest either confirms the system works or finds the problem while it is still the seller's. If a new system is needed inside the window, most installs take a single day once scheduled.

How long does it take? 48 hours of measurement. Where a system is needed inside the same window, most installs go in within a day once scheduled — the constraint is the calendar, not the work.
