Exterior Soft Wash in Bellingham, WA

Exterior House Soft Washing in Bellingham, WA

The same Pacific Northwest damp that grows moss on your roof grows algae, mildew, and lichen on your siding. Those green and black streaks down the north and shaded walls of a house are not just dirt — they are living organisms feeding on the surface, and a garden hose will not touch them. Exterior soft washing removes them at the root and brings the original color of your home back.

Soft washing is the gentle alternative to pressure washing for the exterior of a house. We apply a non-toxic cleaning solution at very low pressure that breaks down algae, mold, mildew, and lichen, then rinse it away. Because it cleans chemically rather than by brute force, it is safe for siding, stucco, brick, and painted surfaces that high-pressure washing would etch, gouge, or strip.

Soft Washing vs. Pressure Washing — What Is the Difference?

Pressure washing uses high-pressure water to physically blast grime off hard surfaces like concrete. Soft washing uses a low-pressure application of a cleaning solution to kill organic growth at the source. The wrong method on the wrong surface causes damage — high pressure on siding can force water behind it, crack stucco, and strip paint. We match the method to the material every time: soft wash for siding, stucco, and painted surfaces; pressure wash only where concrete and stone can take it.

We Protect Your Landscaping — Before and After

Our cleaning solution is non-toxic and eco-friendly, but we go a step further anyway. Before we soft wash any siding, we thoroughly soak the surrounding plants, shrubs, and grass with fresh water, and we soak them again once we are finished. This is usually not strictly necessary, but it dilutes any runoff to a harmless level and keeps your landscaping fully saturated, eliminating any chance of staining or stress to nearby plants.

It is a small extra step that takes a few more minutes on every job, and we do it on every soft wash because protecting your home should never come at the expense of your garden. It is part of what "eco-friendly" actually means to us — not just a gentle product, but a careful process.
