Preston Pipelines, established in 1970 out of a small house in Almaden, California, has grown into one of the Bay Area’s leading Underground Pipeline Contractors. Under the leadership of Mike Preston, Preston Pipelines has built strong client-customer relationships that have been the foundation for its continual growth. With the support of the dedicated and experienced field and office personnel, PPI has earned the trust of customers to complete over 150 public and private projects each year.

Our motto of Service, Integrity, and Quality, has helped us establish our reputation as one of the leading Underground Pipeline Contractors in the state of California. 

Preston Pipelines Inc. was founded by DJ Preston.In the beginning, “Dee” operated a one-man, one-backhoe, irrigation-line repair service for farms and ranches. He built his business by word of mouth, helped by his spotless reputation and dedication to hard work. This led to more jobs and higher visibility for the young company. As a teenager, Mike Preston joined his father, Dee, during high school summer vacations, where he learned the business first-hand – including experiencing the cyclical ups and down of the business and the long hours required for success.

Preston 2_25_04_Page_2_Image_0006Mike enjoyed the work and wanted to expand the company’s horizons. In 1977, with the company then consisting of five full-time employees, Mike agreed to assume field management responsibilities for Preston Pipelines and worked to incorporate more professional management practices into the company’s procedures. Mike was eager to see the company grow. His strengths were the way he dealt with people – his conservative and ethical business approach, and his honesty and integrity. In 1987, Dee Preston transferred ownership of the company to Mike. Two years later, Dee officially retired from the company.


Today, Preston Pipelines Inc. operates under the same principles that were established in 1977. Due to the rigors of the heavy construction industry, and the dynamic changes it has undergone over the last few decades Preston Pipelines has adapted to become more technical, detail-oriented and schedule-driven to provide the much needed expertise to our clients. The company is continuing to grow and has earned a reputation for quality and service that’s unparalleled in the underground construction industry.

Mike Preston takes great pride in the knowledge that the Preston name has become synonymous with service, quality and integrity in underground piping. It has taken a professional management team, supported by dedicated and experienced personnel, to earn the trust that generates the high volume of public and private work Preston Pipelines completes each year.


Preston Pipelines expects to continue to grow and remain an exciting and fulfilling place for all employees to work. Even as we look to expand, we are committed to maintaining that family environment – from the office to the field – that distinguishes us from our competition.
