J. A. Jack & Sons, Inc. started in the 1940's as a small family owned company, producing aglime from a quarry in Arlington, Washington. As industry, and its needs for limestone, grew in the Pacific Northwest, J. A. Jack & Sons grew with it. In the late 1950's the company acquired larger reserves of high-grade chemical limestone and opened its "Imperial" Quarry on Texada Island, B.C.. We still mine our own raw material in order to maintain the highest quality calcium carbonate available in this region.

In the late 1970's, the company expanded into the white calcium carbonate market, extending its product line to now serve almost all needs for various sizing of calcium carbonate for industry and agriculture from its centrally located plant in Seattle.

The company ships bulk and sacked product by rail and truck throughout the Northwest and beyond. It is still a family owned company, but now much larger and offering a much wider array of products. Like many family owned companies, we offer personalized customer service. We also still supply the highest available calcium carbonate product available, which has served its customers for over sixty years.
