What It Is

A precise measurement of Green Isle's air, not a guess.

Radon is a colorless, odorless radioactive gas that rises from the soil and enters homes through foundation cracks, sump pits, and floor-wall joints. We measure it with a continuous radon monitor placed on the lowest livable level under closed-house conditions, recording hourly readings over at least 48 hours.

Results are reported in picocuries per liter (pCi/L) and compared against the EPA action level of 4.0 pCi/L. It's a quick, valuable add-on to a full home inspection. Learn more about radon testing or about home inspection in Green Isle, MN.

Why It Matters in Green Isle

Green Isle is radon country.

Green Isle is a small German-heritage farm town in northern Sibley County, about 23 miles southeast of Hutchinson. Its century farmhouses, older village homes, and surrounding rural acreages each carry their own long history — and that history hides in the parts of a home you can't see.

FAQ

Radon testing questions for Green Isle, answered.

What is radon and why is it dangerous?
Radon is a colorless, odorless radioactive gas that rises from the soil and seeps into homes through foundations. It is the leading cause of lung cancer among non-smokers in the United States. Because you cannot see or smell it, testing is the only way to know whether a home has a problem.
Do I need a radon test in Green Isle, MN?
Yes. The Minnesota Department of Health reports that more than two in five Minnesota homes test above the EPA action level. Sibley County sits in central Minnesota's high-radon region, and the mix of older basements and newer finished lower levels found around Green Isle means radon can accumulate in spaces families use every day. Levels vary house to house regardless of age, so the only way to know your Green Isle home's level is to test it.
How is radon testing done?
We place a continuous radon monitor on the lowest livable level of the home, typically the basement, under closed-house conditions for a minimum of 48 hours. The monitor records hourly readings, which we average and report in picocuries per liter and compare against the EPA action level of 4.0 pCi/L.
How much does radon testing cost?
Radon testing is affordable on its own and even more so bundled with your home inspection. Use the free instant quote tool on this page to see your exact price in about two minutes and book a time.
What happens if radon levels are high?
If your result is at or above 4.0 pCi/L, the EPA recommends installing a radon mitigation system. These systems vent radon from beneath the foundation to the outside and are highly effective. Your report explains the result clearly so you can plan your next step.
