Radon Mitigation in Billings, MT

Billings is the largest city in Montana, home to over 120,000 residents and serving as the county seat of Yellowstone County. With a housing stock that spans more than a century, from historic neighborhoods in the Heights and downtown core to sprawling modern developments across the west end and south side, Billings presents a wide range of foundation types and construction styles. The city's location in the Yellowstone River valley, atop porous sandstone and shale bedrock, creates ideal conditions for radon gas to accumulate in the soil and migrate upward into homes. Yellowstone County is classified by the EPA as a Zone 1 radon area, meaning average indoor radon levels are predicted to exceed the 4.0 pCi/L action threshold. For Billings homeowners, professional radon testing is the only way to determine whether your family is being exposed to this invisible, odorless, cancer-causing gas.

Why Billings Homes Need Radon Testing

The geological formations beneath Billings make the city particularly vulnerable to high radon concentrations. The Yellowstone River valley's sandstone and shale bedrock is naturally rich in uranium, which decays into radium and ultimately produces radon gas. This gas travels through the porous soil and enters homes through foundation cracks, sump pits, pipe penetrations, and construction joints. Billings' cold winters compound the problem because tightly sealed homes create a stack effect that draws radon-laden soil gas upward into living spaces. A significant percentage of Billings homes tested exceed the EPA action level, with some registering concentrations above 10 pCi/L or even 20 pCi/L. Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths each year. A professionally installed mitigation system can reduce indoor radon levels by up to 99%. Call Rim Rock Radon today at (406) 476-7479 for a free estimate and protect your family.
