Understanding Radon in Wisconsin
Radon is a naturally occurring radioactive gas that seeps into homes through cracks in the foundation. It's colorless, odorless, and tasteless — making it impossible to detect without proper testing equipment.
Wisconsin consistently ranks among the states with the highest indoor radon levels. According to the EPA, approximately 1 in 10 Wisconsin homes has radon levels above the recommended action level of 4.0 pCi/L.
Health Risks
Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths annually. Long-term exposure to elevated radon levels significantly increases your risk, even if you've never smoked.
How We Test
At House to Home Inspections, we use continuous radon monitors (CRMs) that measure radon levels every hour over a minimum 48-hour period. This provides the most accurate reading and is the gold standard in radon testing.
Inspector's Tip: Don't skip radon testing just because the home is new construction. We've found elevated levels in brand-new homes throughout Waukesha and Milwaukee counties.
What If Levels Are High?
If radon levels exceed 4.0 pCi/L, a radon mitigation system can be installed. These systems are highly effective, typically reducing levels by 90% or more. The cost ranges from $800 to $1,500 — a small price for your family's health and safety.
