Our radon reduction system works by drawing soil gas from beneath your foundation and venting it above your roofline, so the radioactive gas never has a chance to build up inside your home. It runs quietly in the background, using minimal electricity, and is typically installed in a single day. Most homeowners notice an immediate drop in their radon levels afterwards.
