Addison sits in the Appalachian foothills of southeast Ohio — a region defined by uranium-bearing shale, fractured bedrock, and the kind of soil gas pathways that drive indoor radon higher than the state average. Athens County is classified EPA Radon Zone 1, the highest-risk tier, alongside surrounding counties like Meigs, Vinton, and Hocking. State data consistently shows southeast Ohio counties with average indoor radon readings above the 4.0 pCi/L EPA action level — sometimes well above it.

We've tested and mitigated properties throughout the region: older homes near the Ohio River, newer builds along the SR-7 corridor, commercial buildings in downtown Addison, and rural properties on private well systems where sub-slab conditions vary lot by lot. Our crews know the local soil profile, the typical foundation styles (stone, block, and poured), and which mitigation strategies actually work on Appalachian-Ohio housing stock.
