Radon mitigation in Westerville
What Westerville homes mean for radon mitigation
Westerville's historic Uptown core near Otterbein University holds early-1900s housing on shallow stone or block basements, where soil gas moves through the wall as much as through the slab. The 1960s-2000s subdivisions that ring Uptown are on poured basements with sumps, a cleaner sub-slab suction candidate, and many of the newest ones carry a passive stack ready for fan activation. Because Westerville straddles the Franklin and Delaware County line, both foundation eras sit on the same glacial till that keeps the whole city inside EPA Zone 1.
Westerville's northeast edge borders Hoover Reservoir on Big Walnut Creek, and the rest of the city sits on the flat glacial till plain typical of central Ohio.
