SASHCO, Inc. was founded in 1967 in Buena Park, CA as a commercial window distributer for Southern California’s vast academic campus construction market. Over the following decade, SASHCO evolved into a full-service commercial glazing contractor, providing glass installation services to public schools and hospitals as well as private commercial and residential developments.

In 2004, the company relocated its headquarters to Ontario, CA, from where it operated for 16 years. Looking to positive growth in 2020, SASHCO has once again relocated its headquarters to a new facility in San Dimas, CA, from where it has a base of operation to provide large scale glass and glazing services across Southern California.

SASHCO maintains its reputation as a leading commercial glazing contractor in Southern California, providing only the highest quality, energy efficient, LEED certified glazing products. Our business model is vertically integrated, offering design assist and design build services to general contractors and developers, as well as exterior glazing consulting services to the architectural community.

For over 53 years, SASHCO has partnered with the finest builders including Bernards, C.W. Driver, Clark, Hensel Phelps, Layton, Matt Construction, McCarthy, Morley Builders, PCL, SJ Amoroso, Swinerton, Turner, W.E. O’neil, and many others.

We look forward to forming new partnerships with Southern California builders by providing the same high-quality architectural glazing service, with a professional and safety-conscious attitude, for many years to come.
