Most Mitchell testing calls come from one of two places: a transaction on the clock, or somebody who finally noticed the manometer on a system installed years ago and wants to know whether it still works. The second one is more common than it should be and the answer is often no.
What we see in Mitchell
Older housing near downtown and the Corn Palace, the mid-century block-wall ranches through Sanborn Boulevard and Havens Avenue, and newer building toward Lake Mitchell all sit in Davison County's share of the high-potential zone. Deep till and lake deposits here, no quartzite, same conclusion.
Practical notes for Mitchell homeowners
Existing system verification is a short job and it is worth combining with anything else you need done, because Mitchell trips get grouped along I-90. Ask when we are next headed west on 90.
Radon Testing in Mitchell: the technical part
Verifying an existing system is a different job from testing a house, and it is most of what we do in Mitchell. The question is not whether the house has radon, it is whether the equipment somebody installed a decade ago is still doing anything. That takes a manometer check, a look at the fan, and a 48-hour measurement, in that order and usually in one visit.
What the job looks like in Mitchell
First the gauge, because level liquid ends the diagnosis immediately. Then the fan housing for vibration and bearing noise. Then the pipe run for ice damage or a low spot holding water. Then the device goes in for 48 hours. Where the system turns out to be fine, that is the report, and there is nothing else to sell.
How Mitchell houses are built
Everything from pre-war housing near downtown to steady newer development toward Lake Mitchell and the interstate. A solid stock of 1950s and 1960s ranches with block walls, which are the houses most likely to need real sealing work alongside the system.
Mitchell radon questions
How do I know if my system is still working?
Look at the U-shaped tube on the pipe. Uneven liquid means the fan is pulling. Level liquid means it is not, and the house has been unmitigated for however long that has been true.
Should I retest after replacing a fan?
Always. Fan models are not interchangeable and the wrong CFM can leave a house above 4.0 while the gauge looks perfectly normal.
