Expert Commercial Janitorial Services for the Business Environment

SourceONE’s High Standard Commercial Janitorial Services

SourceONE started with a simple idea—to deliver a higher standard of customer service than any other commercial cleaning services in the Bay Area. Our method of delivering those services has evolved over the years as we bring on new technologies and the needs of our customers change, but our fundamental commitment has remained the same for more than twenty years. From executives to front-line workers to the people behind the scenes, every team member works together to build long-term partnerships with our customers by ensuring we exceed the customer’s expectations. Our commercial janitorial services are second to none because we regard you, the customer, as a very high priority in our manufacturing and office cleaning process. Without you, we wouldn’t be able to do what we love.

Corporate Office Buildings


You want your facility to mirror the quality of business that you provide. You may not know it but the cleanliness of your workspace plays a key role in influencing potential clients and partners, and can also lower the morale and productivity of your employees let alone encourage potential hires to apply. No one wants to work in a dirty and unkempt workspace. That is why expert commercial cleaning services are a must for your business. You may be thinking that if you keep the janitorial services in-house you may save a little bit of money for the same quality of work, but that is simply not the case. You want professionals that know exactly what they are doing and will get everything pristine, down to the nooks and crannies. You also want your employees to focus on their own work, not on keeping the offices clean.

With over 20 years in commercial maintenance and cleaning in the Bay Area, SourceONE provides our services from simple office buildings to multi-building corporate campuses. We make sure to meet with our clients and come up with a customized plan to fit every single one of their needs. We work directly with facility managers, property managers, and owners in order to come up with a plan that is in-depth without pushing you over your budget. No matter how often you need us, we will be there. We even offer day porter services so that you can have the assurance that daily cleaning requirements are met.
