Who We Are

Wiltsie Construction Company, Inc., provides comprehensive steel fabricating, construction, mechanical, and plant-maintenance service solutions for power, chemical, petrochemical, refining, metals and minerals, and other manufacturing and institutional clients.

Headquartered 35 miles north of Syracuse, in Oswego, New York, our company was founded in 1970 to develop and market field construction and plant-maintenance support for power producers and process-control industries across the Northeastern U.S.A.

In 1987, Wiltsie launched a steel-fabricating facility to build stand-alone steel products for industrial and institutional markets and to enhance its service to traditional clients with single-source accountability for the design, fabrication, erection, and finish coating of custom-steel products for industrial requirements. 

Since our founding, we have distinguished ourselves and earned the respect of our customers through our outstanding dependability, performance, quality, and steadfast commitment to excellence. 

Our permanent staff of 50 employees comprises a team of talented professionals— detailers, estimators, project managers, supervisors, field engineers, and skilled craftspeople - committed to building lasting relationships with our customers by producing a quality product and service that meets the highest standards of excellence. This commitment has stood the test of time and will carry us through the 21st Century.
