What Karas & Karas does

Karas & Karas Glass Co. is a 100-year-old, family-owned glass and glazing company headquartered in South Boston, Massachusetts. Founded in 1924 and currently led by owner and president Joey Karas, the company operates two divisions: a Contract Division that delivers full-service curtain wall installation—including engineering, fabrication, and on-site erection using in-house composite work crews of carpenters, ironworkers, and glaziers—and a Wholesale Division that fabricates and distributes glass, mirror, and shower enclosure products to trade contractors throughout the Northeastern United States. The company's principal customers are general contractors, architects, and developers in the Greater Boston commercial and residential construction market for contract work, and trade contractors and distributors across the Northeast for wholesale supply.

The company's technical capabilities center on custom glass fabrication—sandblasting, beveling, polishing, cutting, and tempering—combined with certified specialty products. Karas & Karas is New England's only UL certified provider for FireLite NT, FireLite PLUS, and WireLite fire-rated glass, applies Diamon-Fusion protective coatings in-house, and offers both frameless heavy glass and Alumax framed/semi-frameless shower enclosures. Stock sheet offerings span window, float, laminated, mirror (clear, tinted, beveled, starphire, antique), specialty, and ceramic glass categories. Material supply is anchored by partnerships with Guardian Glass, Gardner Glass (Dreamwalls), Technical Glass Products, All Team Glass, FHC, and Alumax.

Revenue is generated through two mechanics: project-based contracts for curtain wall engineering, fabrication, and installation on multi-year engagements with commercial developers and general contractors, and transactional wholesale distribution of fabricated glass and mirror products to trade accounts. Pricing is quote-based for both streams and not publicly disclosed. Go-to-market is relationship-driven and geographically organized, with an outside sales team covering named territories (Greater Boston, Maine, NH, MA South Shore, CT, RI, VT, and parts of NY) and an inside sales team handling wholesale inquiries across dedicated product specializations including FireLite, tempered, Alumax, and frameless heavy glass.

Expansion highlights3 records

Broad incumbents

• Harmon Inc. One of North America's largest full-service glazing contractors offering curtain wall, custom architectural glass, and installation services. Directly comparable to Karas & Karas' Contract Division but at significantly larger national scale, often competing for the same large commercial envelopes.
• Oldcastle BuildingEnvelope: Large vertically integrated manufacturer, fabricator, and installer of architectural glass and glazing systems. Comparable across both Karas & Karas divisions (wholesale glass supply and curtain wall installation), with broader geographic reach and product portfolio.
• Enclos Corp. National custom curtain wall and facade contractor serving complex commercial buildings. Comparable to Karas & Karas' Contract Division for high-rise curtain wall work but with national reach, larger engineering teams, and the ability to take on larger and more complex projects.
• Vitro Architectural Glass: Major North American flat glass manufacturer producing float and coated glass products for architectural applications. Comparable to Karas & Karas' Wholesale Division as a glass product supplier to trade customers, though Karas & Karas fabricates from purchased glass rather than melting its own.

Direct peers

• W&W Glass LLC: Northeast-based glazing contractor and fabricator specializing in custom curtain wall, storefront, and architectural glass projects. Closest regional competitor to Karas & Karas' Contract Division with overlapping service territory in the New York/New Jersey area and similar custom-fabrication capabilities.
• Standard Bent Glass Corp. Specialty fabricator of bent, tempered, and laminated architectural glass serving commercial construction. Comparable to Karas & Karas' fabrication capabilities for stock sheets, tempered, and specialty glass products supplied to trade customers in the Northeast.
• Dillmeier Glass Company: Mid-Atlantic architectural glass fabricator specializing in custom fabricated, tempered, and decorative glass products. Directly comparable to Karas & Karas' Wholesale Division in terms of custom fabrication, sandblasting, beveling, and trade distribution.
• Technical Glass Products (TGP): Supplier of fire-rated glass and specialty architectural glazing products including FireLite line. Listed as a Karas & Karas supplier partner; directly comparable as a fire-rated glass specialist, though Karas & Karas is also a downstream UL-certified installer of these products.

Regional players

• Glasswerks LA: West Coast-based architectural glass fabricator and distributor offering custom fabrication, tempered glass, and shower enclosures. Comparable product mix to Karas & Karas but serves a different geographic market without overlap in New England.

Others

• Guardian Glass: Global manufacturer of float, coated, and fabricated architectural glass. Comparable to Karas & Karas as a glass product supplier (listed as a Karas & Karas partner) but operates upstream as a raw glass manufacturer rather than a fab/installer.
