The soft wash process, step by step

Soft wash means low pressure plus cleaning solution plus time. The pressure is almost incidental.

We identify the substrate first — painted wood, fiber cement, vinyl, stucco, and brick all behave differently.
Landscaping and beds get wet down so detergent never sits on them undiluted.
Detergent is applied from the bottom up so it does not streak down dry siding.
It dwells long enough to break the growth's hold — this is the step that shortcuts ruin.
A low-pressure rinse carries growth off, top down, following the lap of the siding.
We re-check the north and east elevations, because that is where regrowth starts.

Surfaces we will and will not hit with high pressure

Will not get high pressure	Will get pressure
Painted wood and fiber cement siding	Concrete driveways and pads
Vinyl siding (water gets behind panels)	Pavers (then re-sanded)
Roof surfaces of any kind	Concrete steps and walkways
Sealed decks and fences	Concrete curbs and retaining walls
Screens, vents, and utility covers	Dumpster pads

Moss, mildew, and algae on Willamette Valley homes

These are three different problems and they do not all lift the same way.

Green algae films over the surface and returns quickly if only rinsed.
Black mildew stains into the paint film — it usually needs a detergent wash, and sometimes paint to fully correct.
Moss lifts from the surface but roots into seams, joints, and the gap under siding laps, so pulling it off is not removal.
The pattern matters: growth concentrated on one elevation tells you that side never dries out.
South and west walls in full sun mostly collect pollen and dirt, which is a much easier clean.

Prep, plants, pets, and runoff

Beds and shrubs around the foundation are saturated before any detergent is applied.
Wash water is managed so it lands on your ground, not in a storm drain — Oregon municipal rules restrict that.
Windows and doors are checked for gaps before we start; a loose seal is a leak waiting to happen.
Pets stay inside during the wash and until surfaces dry.
Outdoor furniture, mats, and grills get moved or covered as part of setup.

How quoting works

A house wash quote depends on surface area and condition, so we look before we price.

Tell us the address, the siding type if you know it, and roughly how long it has been since the last wash.
Photos from a couple of angles help us quote accurately without a delay.
If two-story access or steep grades are involved, that affects the quote and we will say so up front.
You get a flat price for an agreed scope. If the job turns out harder than described, we talk to you before we do anything extra.

House wash questions

Is soft washing safe for painted siding?

Yes — and it is the reason we use it. Soft wash removes mildew and algae with detergent and low pressure, so the paint film is never abraded. Blasting painted siding is what causes chalking, streaks, and premature repainting.

How do you get black mildew off without damaging the paint?

The detergent has to dwell long enough to break the growth down, then a gentle rinse carries it off. Where mildew has already stained into the film, washing improves it but only repainting fully corrects it — and we will tell you which one you are looking at.

Do you clean the north side differently?

The method is the same but it usually gets more attention, because north and east elevations stay damp and grow faster. That is the side that comes back first.

Will the water get behind my siding?

Not at soft-wash pressures. Panels are designed to shed rain, and the risk with vinyl is high-pressure spray forcing water past the laps — which is exactly why force is not used on siding.

How often should siding be washed here?

It depends on shade and tree cover rather than a fixed schedule. A shaded wall under firs will need attention far sooner than a sunlit one. We would rather tell you what your specific walls are doing than quote a universal interval.
