How we serve San Francisco

San Francisco is a renter's city — about 63% of residents rent (U.S. Census) — so apartment turnover, recurring upkeep, and move-in/move-out cleans timed to lease dates make up much of our work, alongside whole-home cleaning of the city's Victorian and Edwardian flats. We run regular plans (weekly, every other week, or monthly) and one-time deep cleans from the Mission and Noe Valley through Pacific Heights and the Castro, out to the Richmond and Sunset, and into SoMa's condo towers. The older stock changes the job: ornate trim and molding, bay windows, hardwood floors, and original woodwork need careful, non-abrasive cleaning. The city's hills mean many flats are walk-ups with no elevator, so we plan equipment and access for each building. SoMa and downtown condos often require a certificate of insurance and freight-elevator or concierge coordination — being bonded and insured is what gets us in. San Francisco's climate is cool and foggy rather than humid, so the work here is about detail and turnover, not moisture. Every cleaner on our San Francisco team is bonded, background-checked, and speaks English, Spanish, and Portuguese, so the estimate, walkthrough, and scheduling happen in whichever language is easiest for you.
