Starting a radon mitigation business is a smart and impactful move—but before you begin offering services, it’s essential to understand the legal and professional requirements. In most cases, yes, you will need either a license, a certification, or both to operate legally and credibly.
At Wexford Insurance, we specialize in helping radon mitigation contractors protect their businesses with tailored insurance coverage. In this guide, we’ll explain the importance of licensing and certification, how to obtain them, and how they impact your business growth and compliance.
Why Licensing and Certification Matter
Radon is a radioactive gas linked to serious health risks, including lung cancer. Because mitigation involves altering building structures and installing ventilation systems, states and national organizations regulate who can perform this work.
Licensing and certification ensure that:
You follow recognized safety and installation standards
Clients and regulators trust your qualifications
You qualify for real estate transactions and commercial contracts
You reduce liability and meet insurance requirements
Do I Need a State License?
Yes—many states require a radon-specific license to legally perform mitigation services. These licenses are typically issued by state health or environmental departments and may require:
Completion of a certified training course
Passing a state or national exam
Proof of insurance
Renewal every 1–2 years
States like Illinois, New Jersey, Pennsylvania, Ohio, Iowa, Minnesota, and Florida have strict licensing laws. In other states, certification from NRPP or NRSB may be sufficient, but it’s still recommended to check with your state’s radon program.
National Certification Programs
Even if your state doesn’t require a license, national certification is strongly recommended—and often required by clients, lenders, and real estate professionals.
1. National Radon Proficiency Program (NRPP)
The NRPP is an EPA-recognized certification body offering credentials for:
Radon Measurement Professionals
Radon Mitigation Specialists
2. National Radon Safety Board (NRSB)
The NRSB offers certifications such as:
Radon Measurement Technician (RMT)
Radon Measurement Specialist (RMS)
Radon Reduction Specialist (RRS)
These certifications require training, passing an exam, and ongoing education to maintain your credentials.
How Certification Impacts Your Business
Getting certified isn’t just about compliance—it’s a strategic move that helps you:
Win more contracts by meeting client and lender requirements
Charge premium rates due to verified expertise
Reduce liability and qualify for specialized insurance
Build trust with homeowners, inspectors, and property managers
