The service process
Measure. Confirm. Clean.
A short, repeatable process keeps the estimate and the onsite work aligned.
We identify the siding or exterior material and visible vulnerabilities.
We set expectations for removable buildup versus permanent discoloration.
We wash with a method appropriate to the surface and clean the work area.
Soft washing or pressure washing?
The surface decides the method, not the machine.
Siding, painted trim and older finishes get low pressure and a cleaning solution matched to the green film, then a gentle rinse. High pressure on siding can drive water behind it, lift paint and etch soft materials.
Sound concrete is different. Driveways, walks and patios can take a surface cleaner and pressure, so a house wash and a driveway clean often share one visit with two methods.
Roofs are their own decision. A shingle roof never gets pressure washed; it gets debris removal and a roof-safe moss treatment.
- Oxidized or chalking paint is flagged before we start
- Plants are wet down before and rinsed after
- Each surface is quoted as its own section
Common questions
Questions about house washing.
Is house washing the same as pressure washing?
Not necessarily. Siding often benefits from lower pressure and the right cleaning solution, while durable ground surfaces may use a different process.
Will house washing remove oxidation?
Oxidation and failed finishes can behave differently from dirt or organic growth. We flag those conditions before cleaning and set a realistic expectation.
Can I combine house and driveway washing?
Yes. Combining compatible work in one visit can reduce setup and travel time. The quote will show the selected areas.
What does a house washer in Portland actually do?
A house washer cleans siding, trim and soffits with low pressure and a cleaning solution matched to the material, then rinses. In Portland the target is usually green algae on the north side, mildew under eaves and road film, not just dirt. Windows and concrete are quoted as their own areas.
How much does a soft wash house cleaning cost in Portland?
Most homes run $400 to $800: about $400 for a small single-story, $600 for a typical two-story and $800 for a large or complex exterior. Soft washing is how we clean siding, so the soft wash price is the house washing price.

Green Algae and Black Streaks on Siding: What Causes It in Portland and How to Remove It Without Wrecking the Paint
The green film on the north side is algae, the black streaks are usually the same organism in its dark phase, mold, or roof runoff, and all of it comes off with a low-pressure soft wash. What each stain is, what removes it safely on vinyl, fiber cement, wood and stucco, and what not to do.
