Once a successful harvest is complete, we inspect your grain systems for any issues or trouble-spots that may have developed over the course of the season. We correct those issues by repairing and/or replacing the necessary parts, usually doing so at a lower cost than if they were to be done during the season.

Millwright Service

In addition to the standard maintenance service for grain systems, we also provide general millwright service. From small farms to large co-op elevators, our millwright service is available to customers of any size and is performed by our highly trained technicians. Some of our millwright services include: building conveyor systems, erecting towers, removal/replacement of floors, fans or heaters, custom fabrication and repairs of existing equipment. Contact us to find out how our millwright service can work for you.
