I finally had a radon system installed in my basement last week. The crew sealed all the cracks in the concrete floor and ran a pipe from a suction pit up through the garage and out the roof. It's amazing how quiet the fan is. The test showed levels dropped from 4.7 to 0.8 pCi/L, so I feel much better about the air quality downstairs.
