Company Summary

Coastal Mountain Electric, formerly James Day Construction, Inc. is a contractor company that has been established in Lake County and the North Coast of California since 1958.  Howard D. Day located in Lake County and started an electrical contracting business that involved his family.  His sons worked in that business until Howard passed away in 1985.  Howard's son, Jim, then established James Day Construction, Inc.

David Rogers began working for H.D. Day, Inc. in 1974 and worked on many contractor projects in the Lake County, Ca area including the construction of Indian Valley Dam, California school electrical projects, the Northeast sewer plant project, as well as a wide range of smaller electrical projects spread over Lake County, Ca.

In 1976, David Rogers relocated to Grass Valley, California and was employed by Tesco, a Sacramento based electrical manufacturing company.  This working relationship broadened his knowledge of electrical controls related to pumping plants, traffic control, hydro pneumatic water pressure systems, and an overall education in electrical design.

In 1981, David Rogers returned to Lake County, Ca and worked with H.D. Day, Inc. on contractor projects such as adding electrical power generation to Indian Valley Dam, Cobb Elementary School, sewer plant upgrades, pumping stations, Northern California Power Association plant site construction, Sacramento Municipal Utilities District power plant site construction, and various other electrical projects.

In 1985, David couldn't resist the desire to own his own electrical contractor company and established Rogers Contracting which operated in the North Coast area until 1999 when Jim Day and David reached an agreement for David to purchase James Day Construction, Inc.

During the evolution of that transfer of ownership a motion of change has progressed to introduce Jon Rogers as a leader and director of the company.  Jon's continued efforts and desire to maintain the high standards set by the Day family are the same guidelines he uses to establish Coastal Mountain Electric as a reliable, cost effective, and quality based electrical contracting business.

For the past nearly ten years, James Day Construction, Inc. has been evolving with personnel, equipment, and a passion to improve through education in the electrical industry to keep pace with the ever changing world of electrical installations.
