Northfield Village and Northfield Center Township occupy the Cuyahoga River valley in northern Summit County, placing them in one of the region's highest-radon zones. The deep glacial deposits and fractured bedrock beneath the valley concentrate radon gas and channel it toward homes. We provide certified radon testing and mitigation for the entire Northfield community.
Radon Risk in Northfield
Northfield's valley location creates geology that is particularly conducive to radon accumulation. The glacial deposits here are deeper than in surrounding hilltop communities, and the Cuyahoga River has carved through layers of shale and sandstone, creating fractured bedrock that allows radon gas to migrate freely. Homes along Route 8, Olde Eight Road, and the residential streets off Brandywine Road sit directly on these deposits.
The community's housing stock includes a mix of mid-century homes in Northfield Village and newer construction in Northfield Center Township. Both areas share the same underlying radon risk. The valley's cooler temperatures and higher humidity also mean homes are sealed tighter for longer periods each year, increasing indoor radon accumulation during heating season.

Valley Homes and Radon
Valley communities like Northfield face unique radon challenges. The deeper glacial deposits produce more radon gas, the fractured bedrock provides more migration pathways, and the valley's natural air drainage patterns can trap radon-rich air near ground level. These factors combine to produce some of the highest indoor radon readings we see in Summit County.
The good news is that mitigation is just as effective in valley homes. A properly installed sub-slab depressurization system reduces radon levels regardless of how high they start. We have mitigated Northfield homes with initial readings above 20 pCi/L down to below 2.0 pCi/L.
