Welcome to SiennaStone.  Beautifully crafted architectural elements, made from our crushed limestone aggregate and polymer blend. We design and manufacture columns, window surrounds, mantles, moldings and more. Using the latest CAD software and state-of-the art CNC machinery, we eliminate the cost of traditional mold making methods and the old concrete look of regular precast.  Each piece is hand finished to capture the true character of quarried limestone.

​

Although we offer a wide range of standard colors, textures and profiles, we also take pride in creating unique and custom designs for your project.  Use our catalog of profiles for inspiration or bring your ideas to us.

With SiennaStone, no two projects are the same!
