Our Specialty
The Floor Care Specialists Other Companies Call
Before KCS existed, our founder spent 14+ years stripping, sealing, and polishing floors across the Bay Area. That expertise is still the heart of the company: VCT stripping & waxing, diamond-ground concrete polishing, and marble & natural stone restoration done in-house — never subcontracted.

Frequently Asked Questions
Do you offer residential cleaning?
No — KCS is 100% commercial. We clean offices, schools, medical facilities, gyms, churches, HOA common areas, and retail spaces. Keeping our focus commercial means our crews, equipment, and processes are built for business facilities.
What areas do you serve?
We serve The East Bay, Tri-Valley, downtown San Francisco, Solano County, Sacramento, and the Central Valley — from our Pleasant Hill headquarters we cover Contra Costa County, the Tri-Valley, Oakland and the East Bay, downtown San Francisco, Solano County, the Sacramento area, and the Central Valley down to Modesto.
How does pricing work?
Every facility is different, so we start with a free walkthrough. We look at square footage, floor types, traffic, and your schedule, then send a flat monthly or per-job quote. No hidden fees and no lock-in surprises.
Are you licensed and insured?
Yes — KCS is licensed, bonded, and insured. We're happy to provide certificates of insurance for your property manager or building requirements before we start.
Can you clean after hours?
Absolutely. Most of our janitorial accounts are serviced at night or on weekends so your business never skips a beat. Day porter-style visits are available too.
What makes KCS different from other janitorial companies?
Floors. Our founder spent 14+ years mastering floor care — stripping and waxing, concrete polishing, marble and stone restoration — before building KCS. Most janitorial companies subcontract floor work; we're the specialists others call.
