None of this is required — it just makes the first call faster and gets you a more accurate number.
Duluth, Hermantown, Proctor, Rice Lake, Duluth Township, Two Harbors, Esko, and Cloquet — and the rest of St. Louis County on request.
In a real estate deal with a deadline? Say so when you call. A short-term test needs a 12-hour closed-house period before it starts plus a 48-hour run, so timing matters. See real estate radon testing for how the schedule usually works.
Fill this out and we will get back to you the same day and connect you with an MDH-licensed radon professional serving Duluth. Your name, phone, and email are used only to respond to this request and pass it to that professional — nothing else. See our Privacy Policy.
Bring us the number and the conditions the test ran under. A short-term test that was disturbed by open windows, or one placed too close to an exterior wall, can read misleadingly in either direction. Sometimes the right answer is a second measurement with a continuous monitor before anyone talks about a system, and sometimes the number is clear enough to act on. A licensed pro can tell you which situation you are in.
Call rather than emailing. A compliant short-term test needs the house closed for 12 hours before the device starts and then runs a minimum of 48 hours, so the calendar is usually the binding constraint. Tell us your deadline first and we will tell you honestly whether it fits.
Look at the U-tube manometer on the pipe first — if the liquid is level on both sides, the fan is not pulling. That is usually a failed fan, which is a straightforward replacement. Either way the right follow-up is a fresh test, because the point is the number in the air, not the fan.
Good timing. Testing during the heating season gives you the more conservative number, and if a system is needed you get it installed, permitted, labeled, and confirmed on your schedule instead of during a two-week inspection window with a buyer waiting. See radon testing for how seasonal timing affects the result.
A test settles the question either way. If the number is fine, you are done for two years. If it is not, you will know exactly what fixing it costs.
