Professional Soft Wash Services
for Seattle & Eastside Homes
Gentle yet powerful low-pressure cleaning for roofs, siding, and delicate surfaces. Our soft wash kills biological growth at the root — results last years, not months.
What Is Soft Washing?
Soft washing is a low-pressure exterior cleaning method that uses specially formulated, biodegradable cleaning solutions to safely remove biological growth — moss, algae, mildew, lichen, and bacteria — from your home's exterior surfaces. Unlike traditional pressure washing, soft washing cleans chemically rather than mechanically.
The result: a deeper, longer-lasting clean without any risk of damage. It's the professional standard for roofs, vinyl siding, stucco, EIFS, painted wood, and any other surface where high pressure could cause harm.
Eco-friendly by design. Our soft wash solutions are 100% biodegradable and safe for surrounding vegetation, pets, and your family — while being highly effective against moss, algae, and mildew.
Our Soft Wash Process
Soft washing lets the chemistry do the work — which means a safer, more thorough clean than high pressure ever could on delicate surfaces.
Surface Assessment
We evaluate the surface material, level of biological growth, and any areas needing special attention before selecting the right cleaning solution concentration and application method.
Pre-Treatment & Protection
We pre-wet surrounding vegetation, protect windows and sensitive fixtures, and pre-treat heavily affected areas for maximum effectiveness.
Low-Pressure Application
Our professional equipment applies cleaning solution at low pressure — similar to a garden hose — allowing the chemistry to do the work safely without risk of surface damage.
Dwell Time & Rinse
The solution dwells for an appropriate period to kill biological growth, then we rinse thoroughly, leaving surfaces clean and safe.
Surfaces We Soft Wash
Soft washing is the right method whenever high pressure could cause damage. We soft wash:
Roofs (All Materials)
Asphalt shingle, tile, and cedar shake roofs cleaned safely — no granule loss, no voided warranties.
Vinyl & Fiber Cement Siding
Low-pressure cleaning that lifts moss, algae, and grime without cracking or forcing water behind panels.
Stucco & EIFS
Delicate textured exteriors cleaned gently to remove staining and biological growth without pitting.
Painted Wood
Painted and stained wood surfaces cleaned without stripping finish or raising the grain.
Gutters & Fascia
Exterior gutter faces and fascia boards cleaned of streaking and organic buildup.
Fences & Facades
Fences, retaining walls, and commercial building facades cleaned with the same root-level results.
Why Soft Washing Beats Pressure Washing
Kills Growth at the Root
Pressure washing removes visible growth; soft washing eliminates spores and root systems so it doesn't come back in weeks.
Results Last 2–4 Years
Because it kills chemically, soft washing lasts years — not the 2–4 months typical of purely mechanical cleaning.
Zero Surface Damage
Low pressure means no stripped paint, no granule loss, no water forced behind siding or under shakes.
Biodegradable & Safe
EPA-safe solutions with pre-wet and post-rinse protection for your landscaping, pets, and family.
Built for the PNW
Designed for Seattle's wet winters, mild summers, and heavy tree canopy — the toughest growth conditions in the country.

Fully insured professionals with 8+ years of Pacific Northwest exterior cleaning experience.
Soft Wash Pricing in Seattle
Soft wash pricing depends on the surfaces treated, the size of the area, and the severity of biological growth. Every quote is transparent and itemized — and combining roof, siding, and other surfaces on one visit lowers your overall cost.
Surfaces & Area
Roof vs. siding vs. full exterior, and total square footage, drive the scope. We measure and quote accurately before any work begins.
Growth Severity
Heavy moss and long-neglected surfaces need more solution and dwell time. We account for that upfront, never as a surprise.
Service Combinations
Soft washing the roof and siding together, or adding a house wash, is more cost-effective than booking separately.

Frequently Asked Questions
What is soft washing and how is it different from pressure washing?
Soft washing uses low-pressure water combined with specialized biodegradable cleaning solutions to safely clean exterior surfaces. Unlike pressure washing — which relies on high-pressure water alone — soft washing cleans chemically, not mechanically. This makes it ideal for delicate surfaces like roofs, stucco, vinyl siding, and painted wood where high pressure could cause damage.
Is soft washing safe for my roof shingles?
Yes — soft washing is the only safe method for cleaning asphalt shingle, tile, and cedar shake roofs. High-pressure washing can strip granules from shingles, void manufacturer warranties, and force water under shakes. Our soft wash approach uses low pressure and EPA-safe chemicals to kill moss and algae at the root without damaging your roofing material.
How long do soft wash results last?
Because soft washing kills biological growth chemically rather than just blasting it away, results typically last much longer than pressure washing — often 2–4 years on roofs and 1–2 years on siding, depending on your specific environment and tree coverage.
Are the cleaning chemicals safe for my plants and pets?
All cleaning solutions we use are biodegradable and environmentally responsible. We pre-wet and post-rinse all surrounding vegetation. We ask that pets be kept indoors during the cleaning process, but once surfaces are dry — typically within a few hours — everything is completely safe.
