What Mullins Mechanical & Welding does

Mullins Mechanical & Welding, LLC (DBA Mullins Mechanical) is a privately held, founder-owned mechanical contracting firm headquartered in Carrollton, Georgia, founded in 2008 by Jacob Mullins. The company delivers a unified suite of industrial and heavy-commercial mechanical services, organized around eleven core offerings: design-build applications, process piping, HVAC, plumbing, boiler and chiller systems, equipment installation and rigging, plant relocation and maintenance, metal fabrication, ASME code services, fire protection, and prefabrication. Underlying technical capability rests on a 150,000-square-foot prefabrication facility operated jointly with partner FabLogix, which uses digital-drawing-to-machine automation; ASME R, S, and U certifications authorizing fabrication and repair of pressure vessels, power boilers, and stamped components; in-house NICET-certified fire protection design staff; and qualifying-agent licensure held by the founder across multiple states. Customers include large industrial owners in food and beverage (Diageo, Publix Fresh Kitchen, Hilmar Cheese, Hill's Science Diet, Believer Meats), solar manufacturing (Trina Solar, Canadian Solar, Hanwha Q CELLS), wire and cable (Southwire), automotive (Volvo, Volkswagen, Bridgestone), mission-critical data centers, chemicals (MGC Chemical), aerospace/defense (Pratt & Whitney), and distribution (Amazon, McCormick Spices), with logos such as Lego also appearing on the portfolio.

The business operates a project-based revenue model: each engagement is bid as a one-time contract ranging from several thousand dollars to multi-million-dollar values, with no recurring SaaS, subscription, or license revenue. Sales motion is B2B enterprise field sales, executed both as a prime contractor direct-to-owner (chemical plants, bakeries, poultry processors) and as a subcontractor to large general contractors such as Gray Construction, Haskell, Ryan Companies, Whiting-Turner, Carroll Daniel Construction, and others via a formal pre-qualification process. Customer segments are organized vertically across Industrial/Chemical Processing, Food & Beverage, Manufacturing (including solar), Distribution, Mission Critical/Data Centers, Automotive, Aerospace/Aviation, and Process/Utility. Pricing is quote-based and not publicly disclosed, with project intake forms stratified into $0-50k, $50k-250k, $250k-1MM, and $1MM+ tiers, and revenue recognition tied to project milestones. Geographic reach spans the Southeast as the historical core, with expansion across the Southwest, Midwest, Mid-Atlantic, and Northeast US plus select international projects, and Inc. Magazine ranked the company No. 53 on its 2025 Regionals Southeast fastest-growing companies list.
