Our name says “one day” because that’s how long a mitigation install takes. It doesn’t mean we only show up when it’s convenient. One Day Radon tests and installs radon mitigation systems in the Twin Cities twelve months a year, including the depths of a Minnesota January.
That matters more than it sounds like it should. Radon doesn’t take winter off. If anything, it gets worse.
Cold weather makes Minnesota homes seal up tight. Furnaces run constantly, windows stay shut, and the stack effect kicks in: warm air rises and escapes through the upper floors, which pulls air up from the basement to replace it. That upward pull draws soil gas, radon included, out of the ground and into your living space. The same insulation that keeps your heating bill down in February can trap radon indoors at levels well above what you’d see in July.
That’s exactly why a radon company that slows down in winter is a problem. Homes need testing and mitigation most when demand traditionally drops. We built our schedule around the opposite assumption: radon is a year-round issue, so our crews are too.
Radon Mitigation in Minneapolis / St. Paul MN.
Radon is a radioactive gas that forms when uranium breaks down in soil. Minnesota’s glacial soil and bedrock are unusually rich in uranium, which is a big reason around 40% of homes in the state test above the EPA’s action level of 4.0 picocuries per liter (pCi/L). The gas is invisible and odorless, so the only way to know your level is to test for it.
A radon mitigation system fixes the problem by reversing the pressure that pulls radon indoors. We run a pipe from beneath your foundation to a vent above the roofline, with a fan attached that creates negative pressure under the slab. Instead of soil gas seeping up into your basement, it gets pulled down and out, then vented into open air where it dilutes to nothing. Done correctly, this cuts indoor radon levels by 99%
Radon inhalation is the second-leading cause of lung cancer in the U.S., after smoking. There are no early symptoms, which is what makes it dangerous. People often live with high levels for years without knowing.
It matters for home sales too. Buyers in the Twin Cities are increasingly aware that this region runs hot for radon, and many request a test as part of inspection. A home without a mitigation system risks a price renegotiation or a delayed closing. A home with one, especially with documentation in hand, tends to close faster and with fewer surprises.
That’s the real “one day” difference: fast installs, backed by a company that’s actually there year-round, in every Minnesota season, to do the work.
