We are located in Grass Valley, CA and primarily serve the West Coast. By doing so we maintain a high level of expertise concerning the specific needs of our customers located to this region. Our representatives are some of the most knowledgeable in the industry. And while we have the capacity to sell all over the United States, we don't. We prefer to sell where we live and work, assuring that we are always there, available if you need us. We specialize in contractor sales and have developed a contactor network second to none. If you need a contractor, we will be happy to refer you, at no cost to you. This is entirely at your option and not tied to the building price. Are metal buildings are manufactured by NCI Building Systems, one of the country's leaders in steel buildings. With manufacturing plants located in Atwater CA and Spokane WA (along with numerous others across the United States) delivery and service of your building is readily available. We currently have representatives in Southern CA, Northern CA, and Oregon. If you need a representative at your jobsite, we are available. At Sierra Buildings, customer service is our number one objective.
