GreenTree soft washes Oregon home exteriors, stripping the green algae and grime off vinyl, stucco, and fiber-cement siding that the Willamette Valley’s damp climate grows. Every job is backed by a written price-lock quote, $2M insurance, and our Triple Protection Guarantee.

Most house washing in Oregon runs $250 to $650, depending on size and stories. GreenTree soft washes the siding, which means low pressure plus a cleaning solution, so the algae dies at the root without forcing water behind the panels.
That green is algae, and it loves a damp, shaded wall. Oregon gets about 43 inches of rain a year, so north-facing siding stays wet for months. The algae feeds on that moisture and on airborne dirt.
Western Oregon sits in the Willamette Valley, where mild, wet winters keep siding soaked. Algae shows up first on the shaded north and east walls. Then it spreads, and mildew and lichen join it. Because the growth holds moisture against the surface, it can stain paint, dull vinyl, and work into stucco and wood over time.
There is a value side too. For example, a green, streaked exterior drags down curb appeal and a home’s sale price. A professional house washing strips the growth at the root. In addition, it brightens the siding and protects the paint and material underneath.
Green algae is only the start. Our soft wash also lifts mildew, lichen, cobwebs and wasp nests, pollen, and the road film near busy streets. On top of that, it clears the dingy grey that dulls older paint. High pressure would force water behind siding and gouge soft surfaces, so we soft wash instead, which cleans the wall and protects what is behind it.
From the front of the property to the back, we handle every surface that needs it.
The most common siding here. A gentle soft wash lifts green algae and restores the color without cracking panels.
Porous and easily damaged by pressure. Low pressure plus solution cleans it without chipping or forcing water in.
Durable but best cleaned gently to protect the factory finish and caulk lines.
We clear algae and dirt from brick and mortar without blowing out the joints.
Soft washing brightens painted wood and lap siding without stripping the paint.
Apartments, offices, and storefronts soft washed on a schedule that fits the property.
A four-step process that matches the method to the surface, so it comes clean without damage.
First, we walk the exterior and note the siding type, the staining, and any open gaps. Then we wet and cover plants, lights, and outlets before the wash begins.
Next, we apply a low-pressure cleaning solution that kills algae, mildew, and lichen at the root. The solution does the work, so high pressure never touches the siding.
We then rinse the walls evenly from the top down. As a result, the growth and grime wash away and the finish is left clean rather than streaked.
Finally, we detail the entry, trim, and any tight spots. Then we walk the finished exterior with you, with before-and-after photos on file.
House washing in Oregon typically runs $250 to $650, set by size, stories, and siding type. A single-story home sits at the low end, and a larger two-story home sits higher. GreenTree soft washes and quotes the full price in writing first, with no surprise add-ons.
The price of house washing in Oregon depends on three things. These are the home’s square footage, the number of stories, and the siding material. Every figure is locked in writing before we start, so the quote is the price you pay.
| House Washing service | Typical Oregon price | Notes |
|---|---|---|
| Single-story home | $250 to $400 | Full-perimeter soft wash of the siding |
| Two-story home | $400 to $600 | Adds reach and time for the upper walls |
| Large or three-story home | $550 to $850 | More square footage and access work |
| Stucco or fiber-cement | $300 to $650 | Method and solution matched to the material |
| House wash plus driveway | $400 to $800 | Common bundle, priced together |
| House, roof, and gutters | $700 to $1,400 | Full-exterior package in one visit, best value |
For comparison, repainting a home exterior in Oregon costs several thousand dollars. A yearly house washing removes the algae that ages and stains paint, so it stretches the years between paint jobs for a small fraction of that cost.

Yes, because we soft wash rather than pressure wash. Low pressure plus a cleaning solution lifts the algae and grime without forcing water behind the panels or cracking the siding. That is the safe approach for vinyl, stucco, fiber-cement, brick, and painted wood alike.
That green is algae, and it thrives on shaded, damp walls. Oregon’s 43 inches of annual rain keep north and east walls wet for months, so the algae spreads there first. A soft wash kills it at the root and slows how fast it returns.
Once a year keeps Oregon siding ahead of the algae and mildew the wet climate grows. Heavily shaded homes under trees may benefit from a second wash. A yearly clean also protects the paint, so you repaint less often.
All the common ones. We soft wash vinyl, stucco and EIFS, fiber-cement like Hardie board, brick and masonry, and painted wood. Then we confirm the material at the quote and match the solution and pressure so the finish stays intact.
No. We wet and cover landscaping before we start, control the rinse, and use solutions that break down safely. Protecting your beds, shrubs, and lawn is part of the setup. We have soft washed homes surrounded by gardens without harm.
Yes. Our soft wash uses a cleaning solution that kills algae, mildew, and lichen at the root, not just a rinse that pushes dirt around. That is why the result lasts longer than a quick spray-down with plain water.
A single-story home usually takes two to three hours. Most two-story or larger homes take three to five hours by size. A full-exterior package with the roof and gutters takes most of a day. We give you a clear time window when we lock the quote.
No. Many Oregon clients leave a gate code and go to work. We protect the property, complete the wash, and send before-and-after photos. If you would rather be home, that is welcome too.
Yes, a great deal. A clean, bright exterior lifts curb appeal and helps a home show and sell better. Many Oregon agents recommend a house wash before listing photos, since it is one of the competitively priced ways to improve first impressions.
Yes. GreenTree soft washes multi-unit and commercial exteriors across the Oregon area on a schedule that fits the property. Every job carries the same $2M coverage and written pricing as our residential work.
Yes. GreenTree is Oregon-registered and carries $2M in general liability coverage, with documents on request. That clears the vendor requirement Oregon-area property managers set and protects your home if anything goes wrong.
