What JAMCO does

Johnson Architectural Metal Company (DBA JAMCo) is a privately held commercial curtainwall and windowwall specialty contractor founded in 1981 and headquartered in Marietta, Georgia. The company self-performs the full building envelope lifecycle — design, engineering, fabrication, assembly, mock-up testing, and installation — with all engineering provided by a licensed Professional Engineer and supported by a 25-year warranty. JAMCo operates two fabrication divisions in Cartersville, Georgia (a Curtainwall Division at 500 Donn Drive and a Windowwall Division at 80 Dent Dr NE), and serves commercial real estate developers, property owners, and general contractors across the Southeast US, with a publicly visible portfolio of 41 iconic buildings spanning Georgia, Texas, Tennessee, and the Carolinas.

JAMCo's customer base is enterprise-grade and includes technology firms (Google SE HQ at 1105 West Peachtree, NCR Global HQ, Fiserv), insurance and healthcare (State Farm HQ Phase 2, Anthem I & II, Blue Cross Blue Shield of Tennessee, Children's Healthcare of Atlanta), banking (Regions 615 College Street, Advanced Auto Parts Tower, BBVA Compass Bank/2200 Post Oak, CertusBank), hospitality (W Hotels in Atlanta and Nashville, JW Marriott Nashville), and real estate (Kane Realty's Walter Tower). Revenue is generated through one-time, project-based specialty trade contracts with general contractors and developers; pricing is not publicly disclosed and is scoped per project.

The company runs a direct, relationship-driven enterprise field sales motion, acquiring projects through GC relationships, developer outreach, and inbound inquiries via [email protected], with no dealers, distributors, or reseller channels. JAMCo has accumulated a long-running safety recognition record with the Associated Builders and Contractors (STEP Platinum, Diamond, and Gold awards, plus Safety Excellence recognition from 2004 through 2026) and has received Turner's Outstanding Subcontractor Performance Award three times (2005, 2010, 2025). Leadership is led by CEO Phil Greeves (40+ years in curtainwall, former ABC of Georgia Chairman), President Brett Edell (13+ years across engineering, project management, and sales), and CFO Jim C. Davis (25+ years of construction finance experience, former ABC of Georgia Treasurer).

Broad incumbents

• Kawneer Company (Arconic): Kawneer is one of North America's largest manufacturers of architectural aluminum systems including curtain walls, storefronts, and window walls. It competes with JAMCo on commercial high-rise building envelope projects but at a national, much larger scale as part of Arconic's broader building products portfolio.
• Oldcastle BuildingEnvelope: Oldcastle BuildingEnvelope (CRH plc) is one of the largest North American suppliers of architectural glazing systems including curtain walls, storefronts, and windows. Competes with JAMCo on commercial envelope scope but operates nationally with broader product depth and glass manufacturing integration.
• YKK AP America: YKK AP America manufactures and supplies aluminum curtain walls, storefronts, windows, and entrances for commercial construction. It is a national/global incumbent offering overlapping product lines to those of JAMCo.

Direct peers

• EFCO Corporation: EFCO is a U.S. manufacturer of custom-engineered curtain walls, storefronts, window walls, and entrance systems serving commercial construction. It is a directly comparable product-line competitor to JAMCo's curtainwall and windowwall offerings.

• Enclos Corp. Enclos is a specialty contractor focused on the design, fabrication, and installation of custom curtain wall and building envelope systems for landmark commercial buildings — a closely comparable specialty contractor model to JAMCo.
• Tubelite Inc. Tubelite manufactures and distributes architectural aluminum storefronts, curtain walls, and window wall systems used in commercial construction. It directly overlaps with JAMCo's product offering, though Tubelite focuses more on distribution than integrated installation.
• Wausau Window and Wall Systems: Wausau Window and Wall Systems manufactures custom-engineered curtain walls, window walls, and specialty windows for commercial buildings. As a regional-to-national curtain wall manufacturer, it competes directly with JAMCo's product lines.
• Benson Industries: Benson Industries designs, engineers, fabricates, and installs custom curtain wall systems for iconic high-rise buildings across the United States. It is a specialty contractor with a closely comparable integrated business model to JAMCo.

Emerging players
