Radon Mitigation - Stella, NE

This client was a farmer, and his home was really difficult to find, even a GPS can't detect it. He built the house on 2006 and it has a poured foundation with an unfinished basement with a lot of stuff stored down there. The house had an elevated access point that is large opening into crawlspace that is 11'x12' and has large gravel over dirt. The crawlspace is about 3' tall inside, so won't be an issue. The owner is unsure of levels and hasn't tested in 10 years but said it was high then - we provided him with a charcoal test kit. The homeowner insisted to seal the floor cracks as well. The installation went quick and smooth!
