What is house soft washing?
House soft washing is a low-pressure cleaning method that uses detergent and sodium hypochlorite to kill mold, mildew and algae on a home’s exterior, then rinses it away. High Tide Window Cleaning soft-washes stucco, siding and painted surfaces without the high PSI that can etch stucco or strip paint.

Soft wash vs. pressure wash
Is soft washing better than pressure washing for a house?
For most Central Coast homes, yes. High-pressure water can etch stucco, strip paint and force water behind siding, and it blasts off the surface growth without killing it. Soft washing kills mold, mildew and algae at low pressure, so the clean lasts longer.

Questions
House soft washing questions
How much does house soft washing cost in San Luis Obispo County?
High Tide Window Cleaning charges $150 to $300 for homes under 1,500 sq ft, $350 to $550 for 1,500 to 2,500 sq ft, and $600 to $850 for 2,500 to 4,000 sq ft. Price depends on size, stories and buildup.
Is soft washing safe for stucco?
Yes. Soft washing uses low pressure, so High Tide Window Cleaning can clean stucco, siding and painted surfaces without the etching and paint damage high-pressure washing can cause.
Will soft washing hurt my plants?
High Tide Window Cleaning rinses plants and landscaping with fresh water after soft washing, and covers outdoor electrical outlets before the wash starts.
Does soft washing stop mold from coming back?
Soft washing kills mold, mildew and algae and slows regrowth. On shaded, fog-exposed walls, growth can return over time, which is why many coastal homes are washed every 1 to 2 years.
Can I bundle soft washing with window cleaning?
Yes. Booking a house soft wash with window cleaning or gutter cleaning typically saves about $50 on the total.
