Janitorial Service and Building Maintenance

GMG Janitorial provides complete janitorial service and building maintenance service to commercial clients throughout the greater San Francisco Bay Area. Founded in 1987, by Gina Gregori, our President, the company has grown to service over a million square feet of commercial properties.

Customer Service
We are passionately committed to customer service. We ensure that we are as proactive as possible with each of our clients. For example, many facilities managers waste time and dollars tracking down issues, and managing the service company themselves rather than being able to delegate all this effort. Our management team has over a hundred years of janitorial experience, which combined with the use of leading edge technology, means that often we inform our clients of issues that need to be addressed before they are aware. This allows us to take steps to resolve issues or reduce their impact before a major problem occurs. Client satisfaction is high as shown by the longevity of the relationship we have with the majority of our clients.

Long Term View
We take the long term view in our relationships with clients (both prospective and actual), staff and vendors. Janitorial Service is an intangible product and so it is vital that our customers can easily differentiate our service from those of our competitors.


We use open disclosure on all our sales proposals confident in the knowledge that we deliver on all services contained in a proposal. We are happy to provide free estimates for budget purposes even if we do not make a sale this time. We view this as an important part of relationship building and client service. Through experience we find that when the time is right the client returns and will choose our service.

Operational Excellence
All client services are detailed in our clear and concise contracts which means no buyers remorse. We are accountable for all the duties that have been agreed. Our janitorial staff and management are fully trained in safety and cleaning and in the specific requirements for a client property. Our supervisors are bilingual and ensure the janitorial service is maintained at the highest level on a nightly basis. Regular client walk throughs are performed by our Quality Control Managers, and Customer Service Representatives.

Issue Resolution
We maintain a 4 hour service level response to client email, and regulary "beat" this target. We analyse issue trends so we can be proactive. We consistently identify a reduction in the number of issues facility managers raise once we take over a new client.
