What Superior Glass does
Superior Glass Inc. is a privately held, woman-owned (WBE certified) full-service glass contractor headquartered at 7500 Tower Ave in Superior, Wisconsin, serving residential and commercial customers across Northeastern Minnesota and Northwestern Wisconsin (the Twin Ports area). The company traces its heritage to Kempinsky Glass & Paint (1925) and operates under the Superior Glass Inc. name since 1978, marketing itself with 90+ years of regional experience. Services span the full glass lifecycle — consultation, custom design, fabrication, installation, and repair — across storefronts, curtain walls, windows, doors, shower glass, mirrors, and protective coatings. Technicians hold National Glass Association (NGA) and American Association of Automatic Door Manufacturers (AAADM) certifications.
The company operates as an authorized dealer for premium window brands including Marvin Windows, H Window, Vector Windows, Hayfield Windows, and Thema Tru Exterior Doors, which it sources and installs as part of its residential and commercial offerings. Product breadth extends to mall storefronts, aluminum windows and doors, heavy glass handrails, custom aluminum doors, and glass curtain walls for commercial construction, alongside energy-efficient window replacements and bespoke shower glass for residential customers. Core capabilities emphasize precision installation and custom design rather than proprietary technology platforms.
The business model is project-based and local. Revenue is generated through one-time product sales (branded windows, doors, custom glass) and professional services (fabrication, installation, repair), with quote-based pricing, complimentary estimates, and consumer-friendly financing (0% interest and 365-Days Same-As-Cash with approved credit). Customer acquisition is direct-to-consumer through phone, website quote forms, and in-person consultations, supported by a Facebook page, Google Business Profile, email newsletter, and community initiatives such as the Christmas Giving Project. The company employs 11-50 staff and is independently owned with no disclosed institutional investors or parent company.
