Specialty Mechanical Services Inc

Specialty Mechanical Services Inc has operated from Snellville, Georgia since 1972, making it one of the longer-established mechanical contractors serving the greater Gwinnett County region. The company performs installation work with its own crews across process piping, HVAC systems, material conveying equipment, steel fabrication, and equipment erection. SMS targets a customer base of established property owners, consulting engineers, and general contractors seeking turnkey project delivery including concrete and structural steel components. The business maintains its primary operation center in Snellville while serving surrounding communities including Lawrenceville, Duluth, and Buford.

What distinguishes Specialty Mechanical is its in-house capability model. Rather than subcontracting specialty trades, SMS self-performs process piping, HVAC installation, and steel fabrication using its own trained workforce and hands-on project management. This integrated approach allows the contractor to deliver turnkey installations combining concrete work, structural steel erection, and mechanical systems under a single coordination point. The company emphasizes a team-based project philosophy where same crews handle work from layout through final commissioning, providing continuity that fragmented subcontractor arrangements cannot match.
