Why radon is a problem in Mitchell
Mitchell sits on the James River lowland on deep glacial till and lacustrine deposits, west of the quartzite entirely. Davison County still sits in the high-potential zone that covers eastern South Dakota.
What Mitchell housing is built like
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 is far enough out that trips get grouped. Ask when we are next headed west on 90 and the drive usually costs you nothing.
Who calls us from Mitchell
Most Mitchell calls are one of two things: a transaction on a deadline, or an existing system that somebody has finally noticed has stopped working. The second is more common than it should be, and given that systems installed in the 1990s and 2000s are now well past the 11-year fan life the state publishes, it is going to get more common.

What is particular about Mitchell
There is a wave of fan failures arriving in Mitchell and most of the affected homeowners have no idea. Systems installed through the 1990s and 2000s are now fifteen to thirty years old against an average fan life of about 11 years, which means a large share of the mitigated housing here is running on a fan well past its expectancy or on nothing at all. The diagnostic takes four seconds: look at the U-shaped tube on the pipe, and if the liquid sits level on both sides the system is off.
Common questions from Mitchell
How do I know if my radon system still works?
Check the manometer, the small U-shaped tube on the pipe. Uneven liquid means the fan is pulling. Level liquid means it is not, and the house is currently unmitigated.
Do I need to replace the whole system?
Almost never. The pipe and the sealing last as long as the house. The fan is the wear item and swapping it with a retest is the entire job in most cases.
Scheduling and travel
Seventy-two miles west on I-90 to exit 332, grouped with other trips in that direction. Non-urgent work is worth scheduling against our next run west rather than paying for a dedicated drive.
