Stewart Services Mechanical was founded to assist the Refractory Division with critical projects where conflicting / overlapping scopes of work typically caused the plant delays and cost issues. Stewart Services would single-source and manage these projects to optimize the schedule.
Stewart Services Mechanical has since grown beyond the refractory-related projects to being the major mechanical contractor on outages.
