Multi-site union and non-union general contracting across retail and tenant improvement
N-STORE Services operates two parallel construction brands (union Granger Contracting and non-union N-STORE) serving multi-site retail and tenant-improvement work. The tech stack is almost entirely Microsoft enterprise (SQL Server, 365, Project, Teams, Power Apps)—typical for regional construction firms—but the hiring velocity is accelerating primarily in field and construction roles, suggesting expansion of job capacity rather than automation or platform maturation.
N-STORE Services is a construction contractor founded in 1983, structured around two operating subsidiaries under GNH Services: Granger Contracting (union) and N-STORE (non-union). Both deliver general contracting, retail construction, tenant improvements, store fixture installation, and programmatic maintenance across multiple sites nationwide. The company employs 51–200 people and operates out of Chesterfield, Missouri. Field compliance and safety performance are active operational priorities.
