Certified Radon Services Providers
The Radon Program certifies all radon service providers operating in California. California law requires all radon professionals to be approved by either the
National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB). There are no professional groups that are currently exempt from this requirement, including Home Inspectors, Industrial Hygienists, Registered Environmental Assessors (REAs), and Licensed Geologists.
The California Department of Public Health does not endorse or recommend any company or individual over another. As with any home service, you are advised to get more than one estimate. The lists below are not updated daily; to verify whether a service provider not listed here is certified, you can contact us via email for the most up-to-date information.
Testers
Professional testers can provide test results faster than using a do-it-yourself test kit. Use a professional tester during a real estate transaction. They are also recommended for testing multi-family housing units, schools, non-residential buildings, and anytime you want quick results. The testers listed here have met their board requirements and are certified to operate in California:
