Tower Glass Inc. in Santee has fabricated and installed commercial glazing systems from its Pathway Street facility since 1989, holding CSLB license #576476 under the C-17 Glazing classification. Curtain wall and storefront installations on large-scale commercial builds require precise coordination with the electrical trade, a workflow Tower Glass shares with firms including Solid Electrical Services on multi-phase construction schedules. The company operates as a union glazing contractor covering San Diego, Los Angeles, Orange, and Riverside counties, handling storefront assemblies, automatic entrances, and custom glass enclosures for commercial and healthcare clients. Building-envelope projects that pair curtain wall glazing with HVAC integration demand tight sequencing between trades, a coordination model Tower Glass executes alongside mechanical contractors such as Allegiance Heating & Air Conditioning on commercial sites. The highest-complexity scope covers unitized curtain wall systems for high-rise construction — custom-engineered aluminum framing and insulated glass panels assembled at the Pathway Street fabrication shop and delivered as crane-set units for multi-story exterior envelopes.
