Our Company

SJC (San Joaquin Chemicals Inc.) was founded in 1955 in the San Joaquin Valley in Central California.

In the late 1950s the company was set up to treat water in small industrial cooling systems in order to supplement the founder’s air conditioning mechanical repair business. In 1974 ownership changed to the current owners who sole focus was water treatment and water related services. Today we continue our commitment solely to the water treatment field. Our company has significantly expanded to cover California, Nevada and Arizona. SJC has become a leader in our industry due to the combination of superior solution oriented technical expertise, a guarantee on results and old fashioned integrity
