In the late 1930’s then plastering contractor partners, Al Johnson and Loyd St. John, felt that there was a lack of reliable service orientated material suppliers on the Westside of Los Angeles. So in 1940 they teamed up with Harry Kissel, who worked for one of the largest material suppliers in the Los Angeles area, and started Westwood Building Materials.

Their beginnings’ were very modest with one truck and a thousand square foot building that they built themselves.

Shortly after they opened, the United States was drawn into World War II. Due to the war building materials were unavailable, so in order to keep the business alive Westwood started to sell animal feed.

In 1946, with the post war building boom in full swing, the business moved into a larger facility on Pico Boulevard in West Los Angeles. From this facility, Westwood continued servicing the lath and plastering industry along with industrial materials to the aircraft industries.

In 1958, as the interstate highway system in Los Angeles was expanded, Westwood moved into a larger facility at our present sight in Lawndale.

To this day, Westwood remains a locally owned and operated by the third generation from the St. John family. And as in 1940, Westwood Building Materials still strives to be “The House That Service Built”.
