SourceONE was born out of the vision that we could create a true leader in the Janitorial Services Industry.

SourceONE formed as it became increasingly clear that companies in the Bay Area needed a reliable, professional, multi-faceted building maintenance contractor to service their building maintenance needs. Today, we are an industry leader and offer a broad array of facility maintenance and management services to a wide variety of industries including, leading High-Technology, Green Tech, Bio-Pharma companies and Property Management firms.

We have grown our business from the bottom up; building a solid infrastructure that enables us to pursue our goal of steady growth that expands our geographical reach, our services and the processes that support our team.

We also understand that a great business relationship is built on providing exceptional service, while never losing sight of the personal touch. For more than 20 years, SourceONE has been providing expert service to Bay Area clients in the public and private sectors.
