Early in 1954, Tom Cowdin started Sunset Glass in an unused hangar in the old Bellevue airfield, which was on the north side of Sunset Highway (now known as I-90) across from Eastgate, thus the name. Sunset Glass Company was incorporated with the Secretary of State for the State of Washington in 1959.
By 1957, the hangar was moving so much glass that the facility became too small, so Tom relocated to a building with a rail siding so he could buy glass by the boxcar. Tom found an old feed store with rail siding on the south side of NE 8th St in Bellevue (where Burger King is now located). In 1961, Sunset Glass moved once more to the north side of NE 8th St, just across from where it was (which will be the future home of a Sound Transit station).
Sunset Glass has provided steady employment for many glaziers from the Glaziers and Glassworkers Union. As the business grew, many family members became employed in the office for bookkeeping, sales, etc. Sunset Glass has become a major glass installer for schools, churches, apartment homes, businesses, and family residences of Seattle and the Greater Eastside.
Sunset Glass has been a family-owned and -operated business since its inception; Tom Cowdin passed away in 1989 and left the family business to his children, who still run it to this day. Sunset Glass has come to focus on custom work, from cutting custom glass for shelving and tabletops to installation of custom estate shower enclosures and mirrored wall.
Sunset Glass moved to its 130th St location in 2016.
