Our Story

Art is in our genes.

Living up to our motto "if you can draw it, we can build it" has become increasingly rewarding. Some architecture pushes the design limit, and we are always excited to meet the challenge.

Our combination of state-of-the-art CAD systems, high-tech equipment and technical plastering expertise provide us with all the assets to meet any need. Our focus is on supplying the best available element for any application. Our key people have been involved in the plastering and EPS business for a combined sixty years of experience. From the Fairmont Hotel in San Francisco, the R&D campuses in the Silicon Valley, the casinos of Las Vegas to the thousands of houses, which have added quality and value through architectural elements, have all benefited by our expertise to provide quality elements that work.

The wide range of coatings and finishes, which provide durability and beauty, are many and varied. Our foam is now being used to provide the look and durability of wood, concrete, gypsum plaster and stone. Every day we deliver another product that makes us proud of our abilities, and we strive to make you proud for choosing BayStone.


Complex or simple, raw foam or highly dimensioned. Pre-finished for a fast installation, we provide the experience to help guide our clients to the best possible choice:

  1. Columns and balustrades systems
  2. Cornicing and watertables
  3. Medallions, quatrefoils, quoins and corbelling
  4. Window and Door surrounds
  5. Foam only, base-coated or completely finished

Our shapes are fabricated from virgin expanded polystyrene (EPS). EPS is a rigid, closed-cell insulation material that is white in color. It is a nontoxic material that provides Class 1 flame spread rating (25 or less) and is environmentally sound. Initially made from a petroleum byproduct, virtually all of our scrap is recycled into other post-consumer uses or back into the manufacture of other foam products.

The application of coatings to foam is limited only by your imagination. Our standard application involves the application of a fiberglass reinforcing mesh embedded in an acrylic modified cementitious base coat. The base coat must be tailored to the end finish of the element . Some finishes require different base coats than others. We also utilize epoxy resins, urethane, paints and gypsum-based coatings to foam. Application of finish can vary from conventional stucco to faux paints, a synthetic granite look or glass mosaic tile.
