How can Radon enter my house?
Radon gas comes from the soil that is in direct contact with our home’s foundation. Our home breathes in and out and as our home takes air in, in can pull radon gas into the home through cracks in floors or walls; construction joints; or gaps in foundations around pipes, wires, or conduit. Any hole can be an entrance for radon in our home.
Radon can penetrate your house though many places: it could be a crack in the slab, it could be the plumbing system and more. Therefore, having or not having a basement doesn’t change the possibility that the radon is entering your home.
Radon may also enter the air of a house from well water, but this is a minor source compared to that coming in through the foundation.
