D & D PLUMBING INC

D & D Plumbing Inc. specializes in the installation, repair, and maintenance of plumbing, heating, and air-conditioning systems for mission-critical government facilities. Their demonstrated expertise includes the design and execution of propane supply line upgrades and infrastructure repairs, particularly in sensitive environments such as youth wellness centers. The company applies industry-standard techniques for gas line integrity testing, pressure regulation, and code-compliant piping installations using materials such as CSST and black iron, ensuring compliance with NFPA 54 and local mechanical codes. Their work reflects a strong command of hazardous material handling, ventilation integration, and system commissioning under operational constraints, with a focus on safety, durability, and minimal disruption to facility services. The contractor has delivered services to the Department of Health and Human Services, primarily supporting health and wellness infrastructure where reliable utility systems are essential to patient care and operational continuity. Their engagement with HHS suggests a capacity to navigate stringent facility standards in federally funded community health settings, often requiring coordination with environmental health officers and facility managers to meet regulatory and accessibility requirements. D & D Plumbing Inc. operates exclusively within NAICS 238220, positioning itself as a niche provider of mechanical systems integration for public-sector facilities. Their market focus is on institutional plumbing and fuel delivery systems, particularly in non-traditional healthcare and social service environments where specialized infrastructure needs arise. They are not a broad-spectrum contractor but rather a targeted specialist in utility reliability for community-based government assets. As a small business structured as ZZ with no federal certifications, D & D Plumbing Inc. is locally rooted in Sparks, Nevada, serving regional government and public infrastructure projects. Their geographic presence supports a regional footprint in the western U.S., with an emphasis on responsive, on-site service delivery for state and federally funded facilities in rural and underserved communities.
