In 1917, the Smith family began a small contract trucking firm to serve the people of Napa Valley. Little did they know the company would grow to become a general engineering construction company with ready-mix concrete, landscaping materials and more.
From the beginning, Harold Smith & Son, Inc. has been dedicated to producing high-quality products and reliable service to the residents and businesses in the Napa County community, and after 100 years, they have the experience, equipment and dependable staff to do just that.
