Cascade Radon has reduced radon levels to below the EPA Action Level of 4 pCi/L (picocuries per liter) in every structure we have worked on (frequently below 1.0 pCi/L)...including some with initial radon levels over 500 pCi/L.  

Utilizing state-of-the-art diagnostic techniques, including the use of continuous electronic radon monitors, we provide quick and accurate testing to determine radon levels, aid in system design, as well as assess mitigation effectiveness.  

Our work has included testing, mitigation, consulting, and system design in Oregon, Washington, and California, addressing homes, schools, commercial, public and multi-family properties. This list also includes new "Radon-Resistant" construction projects.  

In addition to our years of experience with radon, a solid background in construction design and building techniques allows us to assess what can and can't be done when installing radon systems.
