When the Army comes calling, you say “yes sir!”. We recently had the pleasure of working for army and installed 5 active systems at a reserve center. After coring through 3 ft. thick walls my guys were beat. But we finished the job. We are letting them work for a few days then performing post mitigation Radon tests to confirm new levels. These pics just show the dedication and skill that my installers have. I truly believe that we are the best Radon company in the country.
