Built on Floors. Trusted With Everything.

KCS — Krystal Clear Service — started with a single specialty: floors. Before founding the company, our owner spent more than 14 years stripping, sealing, and polishing commercial floors across the Bay Area — VCT, concrete, marble, and every kind of natural stone. The kind of work where there's no hiding a shortcut, because the results are literally reflective.

That obsession with visible quality became the foundation for a full commercial cleaning company. Today our crews handle recurring janitorial contracts, deep cleans, post-construction cleanups, windows, carpets, and disinfection for offices, private schools, medical facilities, gyms, churches, and HOA communities across the east bay, tri-valley, downtown san francisco, solano county, sacramento, and the central valley.

We're a family business headquartered in Pleasant Hill, and we've grown the old-fashioned way: property managers who noticed the floors, principals who noticed the crews showed up every night, and referrals from clients like Grace Cathedral School for Boys and 111 Deerwood. We're licensed, bonded, and insured — and we're commercial-only, which keeps our people, equipment, and standards focused on facilities like yours.
