Radon: Radon-Resistant New Construction

Directory of Builders Using Radon-Resistant New Construction

Tools You Can Use

All homes should be tested for radon. Find a qualified service provider near you.

EPA offers the Directory of Builders as a one-stop service to home buyers who are looking for builders that use radon-resistant construction techniques in new homes. The Directory contains the names of builders using RRNC who have voluntarily registered with EPA. EPA encourages all builders that use the recommended radon-resistant techniques to be listed in the Directory. The Directory was last updated on March 12, 2013.

Once you choose a builder, your builder should provide a checklist of RRNC features. Consumers who prefer a third-party or builder verification can look for homes certified or labeled under the following programs that incorporate RRNC techniques:

You can also hire a radon professional to do an inspection of a new home you may be considering purchasing to assess its radon levels. Find certified professionals listed with the National Environmental Health Association - National Radon Proficiency Program or the National Radon Safety Board.

Please Note: EPA does not endorse, promote, or support any individual enterprise, product, or service. The information on the Directory pages was provided by individual builders and has not been verified by EPA.
