National Radon Defense

What National Radon Defense does

National Radon Defense (NRD), founded in 2007 by Curt Drew and headquartered in Omaha, Nebraska, operates North America's largest professional radon service network under a dealer/franchise model. The platform licenses independent contractors as NRD dealers, providing them with brand, training, operational systems, marketing materials, and access to proprietary indoor air quality products. NRD captures revenue across four streams: dealer network/franchise fees, radon mitigation and testing services delivered through the dealer network (sub-slab depressurization, calibrated radon measurement, post-mitigation verification, soil vapor intrusion, and radon-resistant new construction), hardware sales of proprietary IAQ products (Breathe EZ Air Cleaner, Breathe EZ UVC Light, Aspen Air Purifier, SaniDry Sedona dehumidifier, Energy Recovery Ventilator, and AirAdvice for Homes monitor), and air duct cleaning services.

Underlying technology is rooted in conventional radon mitigation engineering rather than algorithmic systems: sub-slab depressurization extracts soil gases through PVC venting, complemented by positive-pressure ventilation (ERV), dehumidification, and multi-stage mechanical filtration. Customer acquisition flows through a national website (nationalradondefense.com), a centralized phone line (1-888-370-6921), and an IAQ Specialist Directory that routes leads to local dealers. NRD serves five distinct customer segments: residential homeowners (the primary segment), HUD-regulated multifamily housing, commercial property managers, real estate transaction counterparties requiring disclosure testing, and franchise/dealer entrepreneurs recruited through the FranNet advisory partnership (April 2026). Geographic reach spans the United States and Canada. Corporate headcount is small (1-10 employees in Omaha), with a 2-day training academy in Omaha plus the NRD Leadership Summit (most recently held July 2023) used to maintain dealer engagement and certification standards.
