Radon Mitigation

Reducing Radon in Structures

If your home has elevated levels of radon above the U.S. Environmental Protection Agency's (EPA) recommended action level of 4.0 picocuries of radon per liter of air (pCi/L), then it is recommended that you fix or reduce the level by installing a radon reduction system (often referred to as a mitigation system).

Do not panic. Any home with elevated levels of radon can be fixed. The methods are straightforward and proven to be effective in reducing radon levels. Mitigation techniques cost no more than other common home repairs.

The method of mitigation depends on theĀ >type of foundation your home has. Methods differ for basements, crawl spaces, engineered floors, slab on grade, or any combination of these foundations. See the photo gallery for examples of correct and incorrect practices.

Hiring a Contractor

If you wish to hire a contractor to complete the mitigation, it is important to select a certified radon mitigation contractor.

Tips for Hiring a Contractor

  • Ensure your contract stipulates that the contractor will follow all EPA protocols regarding radon mitigation and will obtain all applicable local permits.
  • Get bids from multiple contractors.
  • Obtain a guarantee that radon levels will be reduced to 4.0 pCi/L or below.
  • Checklist for selecting a contractor.

Mitigating Your Home Yourself

If you decide to mitigate yourself, information on installation and design are available in the manual Protecting Your Home from Radon, a Step-by-Step Manual for Radon Reduction by D. L. Kladder. It tells everything you need to know about mitigating your home and can be found at your local library or online.
