How To Lower Radon Levels in Your Home

If you have high levels of radon, you will need professional assistance. If the levels are only slightly elevated, you may consider some of these options:

  • Sealing Concrete: This temporarily reduces radon levels in a home.
  • Close Foundation Cracks: If there are visible cracks and other visible openings in the foundation, use calk to close them.
  • Make Sump Pumps Airtight: Do this by using an airtight cover that still allows access to the sump pump, if necessary.
  • Use Polyurethane Plastic Sheeting: Cover exposed soil in crawl spaces with this material. Attach the sheet to the walls and aim for a thickness of 6 millimeters.

If these methods do not lower radon to acceptable levels, consider hiring experienced professionals.
