Radon testing and mitigation is an essential environmental home services sector driven by EPA mandates, real estate transaction requirements, and growing public health awareness around radon as the second leading cause of lung cancer in the US. The industry is highly fragmented with thousands of small owner-operated firms serving regional markets, with demand anchored in residential real estate transactions but expanding into commercial, school, and multi-family segments. Regulatory tailwinds from state-level radon disclosure laws and increasing HUD/VA loan requirements continue to support steady demand growth.
