House Washing FAQ for Seattle Homeowners

How often should Seattle homeowners get house washing?
Given Seattle's 160+ rain days per year averaging 38 inches, most homeowners benefit from house washing at least once a year. Year-round moss and algae on roofs and driveways often makes spring or fall the optimal time to schedule service.
What home types in Seattle most need house washing?
Craftsman bungalows and Mid-century ranches are the most common home types in Seattle 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.
