The state of Washington does not require certification for performing radon services.

However, it is recommended that you become certified, the state recognizes the national NRPP and NRSB certifications and directs the public to these organizations to find certified radon professionals. If you do become certified, it is recommended that you contact the state radon contact to let them know you are certified. Many non-regulated states will recognize and list certified individuals.
