Our history

The beginning of California's Communication Service Company

Communication Service Company started enterprising Low-Voltage solutions for the greater Northern California area in the late 40's. Established a name for ourselves in the 50's-70's while providing telecommunication services for West Contra Costa Unified School District and corporations like Safeway, Long's and Target. In the 70's-90's we started major development projects in downtown Oakland. We then introduced Paging and Intercom systems to our list of services in the late 70's. Followed shortly after by Fire Alarm systems in the early 80's.

Randy Weber takes over as President of Communication Service Company

In the 90's we really hit our stride when we bought out Standard Electric Time along with incorporating Intrusion systems and CCTV to our list of services. In '91 we opened our office in Rodeo, CA.  Taking the correct steps in ensuring the longevity of the company, Randy Weber has bought and modernized the company. Upgrading phone systems, UL accounts and monitoring systems. All while creating strong relationships with customers with providing excellent service with time clock management going into the Y2K era. Pushing the company to new limits and expanding growth.

Corporate office opens in Antioch, CA

Expanding the business further with new clients in the Jefferson Unified School District, Sierra Pacific, Nevato Unified Schol District and Dixie Unified School District. We have expanded to our new Head Quarters of California's Communication Service Company to Antioch, CA. Establishing a firm spot in Low-Voltage Providers and creating a better vantage point of service across Northern California.

Expanding our Low-Voltage expertise to Sacramento, CA

Our office in Rodeo has closed in 2016. Having 67 years in the business providing valued customer service along with quality products at affordable prices has allowed us to expand our service. Opening a new office in the Sacramento area in 2018 has allowed us to provide better service to The Bay Area, all across the San Joaquin Valley and into the Sierra Mountains.
