ZNTH, INC.

ZNTH, INC. specializes in commercial and institutional building construction with deep expertise in roofing, plumbing, heating, air-conditioning, and structural modifications for federal facilities. The company delivers turnkey solutions for critical infrastructure repairs and upgrades, including full roof replacements, wall and footing remediation, and HVAC system modifications. Their technical proficiency spans weatherproofing systems, structural integrity assessments, and code-compliant renovations in high-traffic public buildings such as courthouses, fire stations, and air traffic control centers. ZNTH demonstrates consistent precision in executing complex site-specific repairs under challenging conditions, including differing site conditions and retrofitting legacy structures without disrupting operations. The contractor maintains a strong, recurring relationship with the U.S. Department of Agriculture, delivering essential maintenance on rural and emergency response facilities including fire stations and air attack bases. They also serve the Department of Transportation on mission-critical infrastructure like air route traffic control centers, and have completed minor but vital renovations for the General Services Administration at federal courthouses. Their work reflects a pattern of responsive, mission-driven support for agencies requiring minimal downtime and strict adherence to federal construction standards. ZNTH’s primary focus lies in NAICS 238160 (roofing contractors), 236220 (commercial and institutional building construction), and 238220 (plumbing, heating, and air-conditioning contractors). This positions them as a niche provider of integrated facility maintenance services for federal properties, particularly those requiring durable, weather-resistant envelope systems and coordinated mechanical upgrades. Their market presence is defined by reliability in performing high-stakes, low-margin repairs where safety and continuity are paramount. Based in Santee, California, ZNTH, INC. operates as a small business under the 2L entity structure. While currently holding no formal government certifications, their geographic proximity to key federal assets in Southern California enables rapid mobilization and on-site responsiveness. The company’s positioning is that of a trusted, hands-on contractor for agency maintenance teams requiring technical precision and operational discretion.
