Serving Industrial and Commercial Clients Throughout the Southeast Since 1972.

Cullum Mechanical Construction, Inc. was founded in 1972 by Furman Cullum, whose operations today are comprised of two thriving subsidiaries: Cullum Constructors, Inc. and Cullum Services, Inc. Significant expansion throughout our longstanding history has allowed us to obtain a certificate of authorization for professional engineers and surveyors, unlimited licenses, as a mechanical contractor and general contractor in South Carolina and mechanical and plumbing licenses in North Carolina and Georgia.

Currently, our corporate headquarters occupy 30,000 square feet, with an additional 18,000 square feet of project support space dedicated to sheet metal and pipe prefabrication.
