What Is an NRPP-Certified Radon Professional — and Why Does It Matter?
You’ve had your home tested by a radon professional (or used a free DIY test kit), and the results show elevated radon levels. Now the next question is: Who should you trust to fix it? With so many contractors offering radon services, it can be difficult to know what actually qualifies someone to perform radon mitigation.
Read on to learn how the National Radon Proficiency Program (NRPP) can help you find a radon mitigation contractor, how their curriculum compares to other industry programs, and what to look for when choosing someone to protect your home.
What Is NRPP Certification?
The NRPP is a professional credentialing program for radon industry workers. Its certifications show that the holder has the knowledge and skills to perform radon testing, mitigation, or inspections according to established industry practices.
To earn NRPP credentials, professionals must complete the required training and pass an exam demonstrating knowledge in their credential’s subject area. NRPP exams are based on a combination of EPA and ANSI-AARST National Consensus Standards for radon measurement and mitigation. These standards provide strict guidance for everything from appropriate testing procedures and ethical requirements to system design and installation.
NRPP certification also requires ongoing education. Radon research, technology, building practices, and industry standards are always evolving, so continuing education helps NRPP professionals stay up to date rather than relying solely on what they learned during their original certification.
NRPP vs. Other Radon Credentials
NRPP isn’t the only organization that certifies radon professionals. The National Radon Safety Board (NRSB) also offers credentials, and some states have their own licensing, registration, or certification requirements for radon work. Tennessee doesn’t offer state radon licensure, so credibility is narrowed to the two organizations mentioned above.
But is one credential better than the other? Not necessarily. Both radon programs require professionals to meet education, testing, and continuing education requirements. For homeowners, the key is choosing a contractor with a current, recognized certification and the experience to properly design and install a radon mitigation system.
Are NRPP-Certified Radon Professionals Worth It?
When it comes to radon mitigation, proper installation matters far more than simply having an installation. Radon moves through the soil beneath and around a building and can enter through cracks, joints, openings, and other pathways. Every property is different. Foundation type, construction, soil conditions, and the home’s existing airflow can all affect how a mitigation system should be designed.
An uncertified contractor or DIYer may be able to obtain a radon test kit and install a fan and vent pipe in the name of mitigation, but that doesn’t necessarily mean the system will perform as it should. Poorly located suction points, inadequate sealing, incorrect piping, or improper exhaust placement can all affect system performance.
NRPP-certified professionals, like The Radon Guys, have specialized training that better prepares them to evaluate and design a system tailored to your home’s unique characteristics. They understand that the objective isn’t to simply install some equipment and hope for the best — it’s to reduce radon levels as much as possible to help keep your family safe.
When it comes to radon mitigation, training and experience directly affect the results. The right system, installed correctly, can drop radon levels to safer levels. The wrong system — or an improperly installed one — may not. So, is the cost of choosing an NRPP-certified professional worth it? Absolutely.
How Can You Verify a Contractor’s Certification Status?
If you’re looking for a radon mitigation specialist, you shouldn’t rely solely on a contractor’s website or sales materials to evaluate their credentials. Instead, homeowners can use the NRPP certification portal to look up certified individuals and confirm whether a contractor holds a certification and if it’s current.
You can also ask the contractor directly for their certification information and verify that their credential(s) apply to the services they’re providing.
