What William R. Nash Companies does

William R. Nash Companies (WRN) is a Florida-based mechanical and plumbing construction firm founded in 1965 and headquartered in Tamarac, FL. The company delivers complete mechanical and plumbing services across the project lifecycle, including design-build delivery, BIM-based virtual design and construction, 3D laser scanning, in-house prefabrication, installation, and 24/7 service and maintenance. WRN is a Certified Employee-Owned company (ESOP) and has been a division of HB Global LLC (HB Mechanical Group) since its 2020 acquisition.

The firm serves a diversified set of commercial and institutional end markets, with primary concentration in healthcare (Memorial Healthcare System, HCA Florida, Cleveland Clinic Florida, Baptist Health, Encompass Health), followed by hospitality, correctional, sports and entertainment, high-rise residential, government/military, education, laboratory/R&D, and industrial sectors. Core technologies include BIM-integrated trade coordination, Trimble TX-6 3D laser scanning, an in-house commercial fabrication facility in Tamarac with ASME B31.1, B31.3, and AWS D1.1 welding certifications, and LEED-accredited green building practices.

Revenue is generated through three streams: one-time new construction project contracts (predominantly as a subcontractor to general contractors), recurring service and maintenance contracts including preventative maintenance programs, and custom prefabrication work. The company operates across the Southeast United States, Bahamas, and Caribbean markets, with multi-state contractor licensing in Florida, Tennessee, Kentucky, and South Carolina. As of 2025, third-generation family member Ryan Nash serves as Division President following Russell Nash's retirement after 50 years of service.

Direct peers

Others
