Serving Industrial and Commercial Clients Throughout the Southeast Since 1972.


About Cullum

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. To enhance our service capabilities and the level of direct support we offer, we also operate HVAC repair and HVAC service locations in Columbia and Greenville, South Carolina.

A Letter from Our Chairman

The world has changed drastically since 1972. When Cullum was started by Furman Cullum five decades ago, the Watergate scandal transformed the country, and Bob Barker hosted the first episode of the iconic show The Price is Right. Technology was far from what it is now. As a company that has transformed the mechanical maintenance and construction industry over the past 50 years, our story has close ties to history’s development. And now, as one of the Southeast’s largest mechanical contractors, our success has been made possible because of the partnerships and relationships we have formed with our stakeholders, employees, and clients.

To all of Cullum’s current and past team members, I want to say thank you for all of your hard work. It is because of you and your dedication to Cullum’s values, mission, and vision that we have created a reputation for delivering excellence to our clients.

To our clients, we appreciate you for trusting us to provide the mechanical and construction services you need. To this day, we are committed to providing the best value with our projects, and we appreciate every opportunity you continue to give us.

To our suppliers, subcontractors, design professionals, and code officials, your partnerships continue to empower our organization to conduct our operations. Because of your collaboration with us, we have provided mechanical and construction services over the years that have improved the buildings that people use every day.

And finally, we want to say thank you to the communities where we operate. One of our goals is to contribute to the environmental, economic, and social success of the communities we serve by providing employment opportunities and running an ethical and responsible company.

We will maintain our relevance in a continually changing world and industry by continuing to listen to and understand the needs of the communities where we work and the clients we serve over the next 50 years. Again, thank you for all your support on this journey. We are excited to see what the next half century holds!

Thank you,

Chris Cullum
