About Cullum Mechanical
Cullum Mechanical Construction, Inc. was founded in 1972 by Furman Cullum in Charleston, South Carolina. Over the next few decades, the company experienced substantial growth across the state. By 1999, Cullum’s operations expanded into two specialized subsidiaries: Cullum Constructors, Inc. and Cullum Services, Inc.
These subsidiaries quickly became leaders in the mechanical contracting industry, recognized for providing innovative solutions and exceptional service throughout the Southeast. This growth solidified Cullum Mechanical’s reputation for excellence and expanded its capabilities in mechanical construction and HVAC services across South Carolina, North Carolina, and Georgia.
In 2023, strategic plans began to ensure continued leadership in the industry with the formation of Cullum Mechanical, LLC. This strategic transition represents an exciting milestone, reflecting the company’s commitment to evolving with industry demands, providing future leadership, and continuing to deliver reliable, innovative, and efficient mechanical solutions.
For over 50 years, Cullum Mechanical has been rooted in tradition, driven by innovation, and inspired by a mission to serve clients better.
Today, Cullum Mechanical’s corporate headquarters in North Charleston, South Carolina, spans 30,000 square feet, with an additional 18,000 square feet dedicated to project support, including state-of-the-art sheet metal and pipe prefabrication facilities. To further enhance service capabilities, Cullum Mechanical also operates HVAC repair and service locations in Columbia and Greenville, South Carolina.
