Mechanical Division

Plumbing, HVAC & Hydronic Installation

Licensed mechanical installation delivered through Sentry’s in-house Mechanical Division. Supporting commercial construction, industrial facilities, and infrastructure projects across the region.

Sentry’s Mechanical Division provides licensed mechanical installation for commercial construction, industrial facilities, and infrastructure projects. Our in-house team delivers plumbing, HVAC, and hydronic systems for new construction, major renovations, and facility upgrades.

Mechanical work is executed with a construction-first approach. Sentry coordinates mechanical installation with structural, electrical, and controls scopes to support project schedules, reduce conflicts, and ensure systems are installed correctly the first time.

Sentry is licensed in South Dakota, Minnesota, and North Dakota. Our Mechanical Division includes licensed Master Plumbers and experienced field crews who understand how mechanical systems integrate into larger construction projects. We focus on code compliance, system performance, and long-term reliability.
