National Radon Defense Opportunity
National Radon Defense was founded in 2007 by Larry Janesky, the respected entrepreneur behind Basement Systems and Dr. Energy Saver. Recognizing that radon — the leading cause of lung cancer among non-smokers — lacked a professional mitigation network, Janesky built NRD to elevate industry standards and protect families nationwide.
Since beginning franchising in 2010, National Radon Defense has grown to 57 locations across the United States and Canada. The company developed proprietary mitigation products, testing equipment, training protocols, and the Radon Shield Pro software platform that powers franchisee operations. NRD has become the most recognizable name in radon risk reduction and indoor air quality services in North America.
The model addresses an underserved market with built-in demand. Millions of homes contain unsafe radon levels, and real estate transactions increasingly require testing and mitigation. EPA awareness programs continue expanding, driving homeowner action and creating consistent lead flow for certified professionals.

ABF Exclusive Insights
Market Analysis: Radon is the second leading cause of lung cancer in the United States, yet public awareness remains low. The EPA continues increasing nationwide awareness while states tighten mitigation regulations. This combination of health risk, regulatory pressure, and real estate transaction requirements creates sustained demand for certified professionals.
Competitive Advantage: National Radon Defense owns the category with 57 locations, proprietary equipment, and 15+ years of operational refinement. Independent operators lack the training, technology, and brand trust that NRD provides. Franchisees enter as credentialed experts backed by America’s largest network.
ABF Investment Tip: Ideal for entrepreneurs seeking a purpose-driven business with strong margins and semi-passive potential. The low investment ($60K-$80K) and home-based model reduce startup risk. Multiple revenue streams — radon testing, mitigation, indoor air quality upgrades, and commercial contracts — provide diversification and year-round cash flow.

Technical experience is not required — NRD’s training provides all necessary certifications. Strong candidates are committed to quality work, comfortable managing teams, and passionate about improving indoor environments.
