Areas we serve
We test and fix basements across Chicago's North Shore, and every town on this list has its own reasons a radon number can run high. Pick yours to see what its housing stock, soil, and permit office mean for your house.
Four out of five homes predate radon codes: a 1960s-70s building boom of ranches, split-levels, and Colonials with no built-in defense.
