Where We Work
KCS is headquartered at 2855 Contra Costa Blvd, Suite C, Pleasant Hill — and our crews cover the east bay, tri-valley, downtown san francisco, solano county, sacramento, and the central valley. Click your city for local service details.
Our home turf. From our Pleasant Hill headquarters we serve office parks, medical plazas, schools, and retail centers across central and east Contra Costa County — often with same-week walkthroughs and rapid response times.
Bishop Ranch, Hacienda Business Park, and the corporate campuses of San Ramon, Pleasanton, Dublin, Danville, and Livermore. Class-A office standards, delivered by night crews that leave no trace but clean.
Oakland, Berkeley, and the I-880 corridor down to Fremont — a dense mix of offices, biotech, warehouses, schools, and civic buildings where dependable janitorial service is the difference between tenants staying and leaving.
We serve the downtown core — Financial District, SoMa, Union Square, and Nob Hill — where we already maintain private schools and landmark facilities. High-rise office suites, schools, and churches are our specialty here.
Vallejo, Fairfield, Vacaville, and the I-80 corridor. Growing business parks, medical offices, and logistics facilities that deserve big-city cleaning standards without big-city vendor attitudes.
Downtown Sacramento to Roseville, Rocklin, and Folsom. We bring our floor-care specialty to the Capitol region's offices, schools, and medical facilities — with local crews and Bay Area quality standards.
Stockton, Tracy, Manteca, Lodi, and Modesto. Distribution centers, offices, schools, and retail along the I-5 and Highway 99 corridors — cleaned on schedules that work around your operation, not against it.
