Protect Environmental

Protect Environmental

Founded in 2005 and headquartered in Louisville, Kentucky, Protect Environmental began as a regional radon-mitigation contractor before expanding across all 50 states plus Puerto Rico and the US Virgin Islands. The firm positions itself as the nation's largest radon contractor, anchoring its growth on an internalized installation workforce rather than subcontractor networks. Protect Environmental's deployment spans residential and commercial segments. Residential services include radon testing, active soil-depressurization system installation, and ongoing system maintenance — often financed through its GreenSky partnership. The commercial division handles radon, soil-gas, and vapor-intrusion mitigation for new construction and existing buildings, selling its proprietary Radon Sentinel and Vapor Sentinel monitoring hardware. Geographic coverage extends from the Midwest origin market through coastal metros, supported by a local-office model that the firm highlights as a route to market for developer relationships. The firm has not publicly disclosed total capital deployment, AUM, or team size. Its website refers to a workforce distributed across the US but provides no headcount. No adjacent investment vehicles, philanthropic foundations, or co-investor clubs are mentioned in available primary materials. Unlike diversified environmental consultancies that treat radon as one service line among many, Protect Environmental is structurally a specialty contractor operating at national scale. This single-hazard focus allows it to own the full value chain — from testing equipment and monitoring hardware through installation and long-term maintenance — a vertical integration that is rare in the fragmented radon-mitigation industry. Succession and governance details remain unpublished.
