Radon mitigation in Lancaster
What Lancaster homes mean for radon mitigation
Lancaster's substantial 19th-century core, including the Georgian-era housing stock the city is known for, sits on stone and early masonry foundations where soil gas commonly enters through the wall itself rather than a single crack. Fairfield County is in EPA radon Zone 1, and the mid-century and modern growth ringing the historic core sits on more conventional poured basements or slabs where a standard sub-slab system applies.
Lancaster sits along the Hocking River at the base of Mount Pleasant, and the historic core downtown follows the river valley's original street grid.
