Frontier Contracting, Inc. was established in Sonoma, CA in July 1997. Frontier possesses a combined more than fifty years of experience in the heavy construction industry between the management staff.

Our company can be characterized as a general contracting construction company engaged in heavy and industrial construction projects. Frontier deals primarily with construction of public works projects in Northern California, specifically, flood control projects, pipelines, wastewater/water treatment facilities, pump stations and other types of public works. We have also performed work on federal projects including The Corps of Engineers and U.S. Coast Guard.

Additionally, Frontier is a certified Butler® Builder and can provide a complete package from design to completion of a top quality metal building.

We believe Frontier Contracting, Inc. is separated from its competitors by our "Can-Do" attitude, the ability to self-perform ninety-five percent of contract work and our partnering work approach.
