Certified Radon Mitigators
in South Bend, Indiana

South Bend and St. Joseph County sit in northern Indiana near the Michigan border, where glacial deposits from multiple ice advances over Silurian limestone create elevated radon across the metro area. Northern Indiana is EPA Zone 1, and South Bend-area homes — from older housing stock near Notre Dame to mid-century ranches in Mishawaka and Granger — test above the action level with regularity. Indiana's 5.6 pCi/L statewide average reflects the type of geology that underlies St. Joseph County, and most South Bend homes with basements or slabs benefit from testing. Indiana requires state certification for radon contractors.
