House Washing FAQ for San Francisco Homeowners

How often should San Francisco homeowners get house washing?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from house washing at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need house washing?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
What's the difference between soft washing and pressure washing?
Pressure washing uses high water pressure to mechanically remove surface dirt. Soft washing uses low pressure combined with professional cleaning solutions that kill and remove biological growth — algae, mold, mildew — at the root for longer-lasting results.
Is soft washing safe for painted siding?
Yes. Soft washing is actually recommended for painted surfaces because high pressure can chip, peel, or damage paint. Our solutions are formulated to clean without harming exterior finishes.
How long will house washing results last?
In most climates, professional soft washing keeps exterior surfaces clean for 2–4 years. Homes in very humid environments or under heavy tree cover may need cleaning every 1–2 years.
