Janitorial Maintenance Services San Francisco, CA

Family Owned

Trinity Building Services is a family owned and locally operated business that has provided superior janitorial and maintenance service to commercial and residential clients since 1987.

As a family-owned business, we can give you the personal service not normally found in larger, impersonal janitorial companies. We don’t have corporate restraints, nor reporting burdens normally associated within the institutional culture. We have the management time available and the commitment of our entire team to implement and maintain best-in-class cleaning programs for our commercial clients.

Trinity has several locations throughout California, which ensures management availability and depth of supervision and personnel from which to provide additional people of equipment whenever necessary. Our flexibility is largely in part to our experienced management and the large pool of skilled personnel we employ from the local community. Our supervisors are bilingual, dedicated professionals whose primary concern is customer satisfaction and delivering on expectations.

Trinity is a facility service provider that provides superior janitorial, maintenance, security services, and maintenance services to commercial clients throughout California and Arizona.

Since 1987, Trinity has been using best in class cleaning equipment to provide businesses with the peace of mind that comes with a refreshingly clean office space. The fact is, for more than 30 years Trinity has been around for one sole reason—to provide you with a cleaner, healthier environment for your facility.

With a long-standing tradition of innovation, hard work, integrity, and outstanding customer service, Trinity has enhanced the cleanliness and safety of all the commercial facilities that we have serviced for over 30 years!

Very easy to work with and flexible. Have come through for us on short notice several times when we needed security for events. The guys that show up are real pros and have been in the industry for years. It was way too much of a hassle to come up with security on short notice on our own and Trinity is a great option. Highly recommended!

I have been a client of Trinity Services for a year now and have found their janitorial services to be very reliable and worthwhile. If you are looking for a good cleaning service for an office space, Trinity is a great option. The staff is always professional, and the business is well managed. I highly recommend them if for janitorial services in the Bay Area.

Normally, I wouldn't leave a review for a janitorial cleaning company, but the team at Trinity is more than just a cleaning service. Trinity acts as a one stop shop for all our building services: janitorial, security, and building maintenance. They are a family-owned company that has a quality team and services. I can always rely on their team to show up.

The service is great. Lehua takes care of customer service needs. She is always pleasant. Sylvia has been the supervisor for the janitorial staff for many years and will always make sure you get a really good bid and does a great job of overseeing the clients' needs. The janitors do such a good job; there are very few complaints. Their rates are awesome.

They did an amazing job - they showed up on time, and our office is sparkling clean. They offer the BEST janitorial and commercial cleaning services in the SF Bay area.
