According to a national residential radon survey completed in 1991, the average indoor radon level in the United States is 1.3 picocuries per liter (pCi/L). The average outdoor level is about 0.4 pCi/L. Excessive radon levels have been found in all of the 50 states.
Our goal is to reduce radon as close as possible to the average outdoor level of 0.4 pCi/L. Almost 90% of the homes we mitigate re-test between .5 and 1.5 pCi/L. Our guarantee is always to below 4.0 pCi/L at a minimum.
