Radon Mitigation
There is no known safe level of radon. However, most homes can be successfully mitigated with levels above 2 pCi/L. This usually involves the installation of a pipe and fan that removes the gas from under the foundation, and pumps it up and away from the home.
If your home tests higher than 2.0 PCi/L then call the Flagstaff Radon Hotline at 888-585-9985 to discuss your options.
