Radon Levels Went from 7 to under 1

From Angies List 05/02/16 – They were excellent — came on time, took about 6 hours (as estimated), cleaned up and did neat job.  Brian, the foreman, kept me informed and explained the system.
We had the radon tested before and after — went from 7 to under 1.  We will definitely recommend to friends and use again if we move and find radon.

Description of work:

They put in radon mitigation system — broke through concrete basement floor, pipe out to garage, up through roof with fan in garage attic.
