Our Softwashing Process

Surface Pre-Rinse

Surrounding plants, landscaping, and surfaces are pre-wetted and protected before any chemicals are applied.

03

Solution Application

Our biodegradable soft wash solution is applied at low pressure, saturating the surface and killing biological growth at the root.

The solution is allowed to dwell for optimal effectiveness, then thoroughly rinsed away with low-pressure water.

Softwashing FAQ for Portland Homeowners

How often should Portland homeowners get softwashing?
Given Portland's 37 inches of rain annually spread across 144+ rain days, most homeowners benefit from softwashing at least once a year. Moss and lichen removal from roofs (treated October–March) often makes spring or fall the optimal time to schedule service.
What home types in Portland most need softwashing?
Craftsman bungalows (extremely common in inner Portland) and Victorian homes in Irvington and Alameda are the most common home types in Portland and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How is softwashing different from pressure washing?
Softwashing uses very low water pressure (similar to a garden hose) combined with cleaning agents to kill and remove biological growth. Pressure washing relies on force alone, which can damage surfaces and doesn't kill the organisms causing staining.
Is softwashing safe for my plants and landscaping?
Yes. We pre-wet all landscaping and use biodegradable solutions. We also rinse surrounding areas thoroughly after treatment.
How long do softwash results last?
Softwashing results typically last 2–5 years depending on your climate and shade conditions, significantly longer than pressure washing alone.
Can you softwash a roof?
Absolutely. Softwashing is actually the recommended method for roof cleaning — it removes black algae streaks without voiding roofing warranties or damaging shingles.
