Single-Source Systems
Most dealers supply equipment but subcontract installation and service. Sentry is different. Our FieldWorks division coordinates foundations and site work. Our Structural Steel team erects bins and buildings. Our Electrical division wires every component. Our Controls & Automation team builds UL-listed panels in-house.
Our Crane Service handles heavy lifts, and our service teams respond when systems need repair or upgrades. The result is faster project execution, better system integration, and long-term support from teams who know your system inside and out.
Delivery & Self-Perform
Sentry offers General Contracting, Construction Management, Design-Build, and EPC delivery models.
What sets us apart is our ability to self-perform critical scopes, giving owners greater schedule control and predictable results. Divisions include Electrical, Mechanical (Plumbing/HVAC), Controls & Automation (UL-listed OEM panels), Structural Steel, Manufacturing, Crane Service, and FieldWorks.
Challenges We Solve
- Managing complex installations across multiple trades, vendors, and tight seasonal deadlines
- Coordinating foundation work, structural erection, electrical, and controls with separate contractors
- Accessing qualified service teams for emergency repairs during critical harvest or growing seasons
- Integrating new equipment with existing grain handling, irrigation, or facility infrastructure
- Finding a single point of accountability for warranty service, system upgrades, and long-term maintenance
