About Us: GreenTree Services, an Exterior Cleaning Company in Corvallis, Oregon
Here is everything about us that a buyer can check. It covers who runs GreenTree Services, where the crews work, and also what they refuse. The company dates from 2022, when it started in Corvallis. Since then, crews have cleaned the outside of homes and business buildings across the Willamette Valley and the Portland metro.
Checked 1 October 2026 against the Oregon Secretary of State business search and three cleaning sources. Those sources are ARMA, James Hardie and Oregon DEQ.

GreenTree Services in three answers
Three answers cover the basics of checking any company. Here, then, are the plain answers about us, and each one points to a record.
Who founded GreenTree Services, and when?
GreenTree Services is a Corvallis company, founded there in 2022. It sets the pressure, chemistry and documentation standards the crews work to. Since then the company has cleaned more than 500 properties, a figure the owner confirmed in September 2026. Its office, meanwhile, sits at 1460 NW Van Buren Ave in Corvallis.
Where does GreenTree Services work from, and which Oregon cities does it serve?
GreenTree works from Corvallis and serves the Willamette Valley plus the Portland metro. In the valley, that means Salem down to Eugene and Springfield, including Albany, Lebanon and Philomath. Metro pages also cover Portland, Beaverton, Hillsboro, Lake Oswego, Gresham and more. The full city directory, however, sits near the end of this page.
How is GreenTree Services registered and insured?
Anyone can search registry number 2424331-91, the entry GreenTree Services holds with the Oregon Secretary of State. That entry is a registration, though, rather than a construction contractor license. Its insurance runs to $2 million of general liability, and workers compensation sits alongside it. On request, the insurance certificate goes out before a crew arrives.

What does a GreenTree visit include, and what does the crew refuse?
The outside of a building, plus inside window glass when booked: that is the whole scope of a GreenTree visit. Roofs, siding, gutters, concrete, decks, fences and windows qualify. Deck staining, holiday lights and solar panel cleaning also sit on the list. Repairs, sealing, tree work and painting go to the right trade.
Services GreenTree offers, each with its own guide
- Pressure washing: the strongest setting is for bare concrete alone, while pavers and stone get a lighter touch.
- House washing: siding gets a soft wash under 500 PSI, so the solution lifts the grime.
- Roof cleaning: the crew lifts moss by hand and rinses low, because shingles cannot take a pressure washer.
- Moss removal: the guide explains how, and also when, the crew clears moss from roofs, paths and patios.
- Gutter cleaning: leaves and grit come out of the troughs, and each downspout then gets a running-water test.
- Driveway and concrete cleaning: oil spots take a degreaser before the rinse goes on.
- Sidewalk cleaning: slick film comes off the paths people use, especially before the wet months.
- Deck and fence cleaning: low-pressure cleaning, then staining if you want it, while carpentry goes elsewhere.
- Window cleaning: a water-fed pole with purified water handles panes and also skylights.
- Solar panel cleaning: glass only, since the wiring and the array itself stay outside the job.
- Holiday light installation: lights go up for the season and come down again afterwards.
- Commercial exterior cleaning: storefronts, offices, apartment sites and HOA grounds, each with a written scope before work starts.
- Pre-sale cleaning and property manager programs bundle these services when a listing or a portfolio needs several at once.
Work GreenTree turns down, and who to call instead
| Request | Who to call |
|---|---|
| Roof repair or re-roofing | A licensed roofer, since the crew only cleans roofs |
| Gutter installation, gutter repair or gutter guards | A gutter contractor, because GreenTree only clears gutters |
| Siding installation or rotten trim | A siding contractor or a carpenter, before any wash |
| Soft deck boards or structural deck repair | GreenTree handles this as part of its full deck package, and it can stain the new boards. |
| Driveway, patio or concrete sealing | A sealing contractor, while GreenTree handles the cleaning beforehand |
| Tree removal or storm cleanup | An arborist, since the crew works around branches rather than cutting them |
| Drain cleaning | A plumber, because drains sit outside exterior cleaning |
| Interior cleaning or carpet | An interior cleaning company, since GreenTree cleans exteriors and window glass only |
| Painting | A painter, though GreenTree can wash the walls first |
| Junk removal | A hauling service instead |
| Car detailing | A detailing shop instead |
| Electrical work on a solar array | A licensed electrician, while GreenTree cleans only the glass |
If a surface needs repair, the right trade should fix it first. Cleaning comes afterwards. Ask us about any job on this list, and we will name the kind of trade to call.
Which cleaning method does GreenTree use on each surface?
GreenTree matches the method to the material, so no single pressure setting covers a whole property. Bare concrete, for example, takes full pressure with cold water. Painted wood and every kind of siding, however, stay below 500 PSI on a soft wash. Shingle roofs never meet a pressure washer, while windows get purified water from a pole.
Roofs: hands and a low rinse
Shingle roofs are where the Asphalt Roofing Manufacturers Association draws its hardest line. Granule loss and very likely premature failure of the roof are the results it predicts from a pressure washer. That is why the crew lifts thick moss by hand and keeps the rinse low.
Siding: solution first, gentle rinse after
A soft wash is cleaning by chemistry rather than force: solution goes on, dwells, then rinses off at low pressure. James Hardie, for instance, tells owners of its fiber cement siding not to use a high-pressure power washer. Its advice instead: a low-pressure hose and a soft, medium-bristle brush that is not metal. GreenTree also holds vinyl, wood and painted siding to the same low-pressure limit.
Concrete and stone: full force only where it belongs
Poured concrete, however, is the one surface that takes the full force of the machine. A rotating surface cleaner keeps the passes even, so the slab dries without stripes. Joint sand and soft stone wear away fast, so pavers and natural stone get a gentler setting.
Rinse water: onto soil, not into the street
Oregon DEQ guidance covers wash water from building and pavement cleaning when detergents go into the mix. Soil can take it, and so can a sanitary sewer or a treatment system. GreenTree thus sends its rinse toward lawn and beds, never into a storm drain.
Windows: purified water on a pole
A water-fed pole is a long pole that carries purified water up to a brush at the glass. GreenTree uses one for window cleaning, and also for skylights.
What does GreenTree charge for its main jobs?
These bands match the Oregon cost guide, so you can compare before calling. Your own number comes from photos or a site visit, then goes on paper.
| Job | Price band | What moves the figure |
|---|---|---|
| Two-car driveway | $299 | Mostly slab size and oil staining |
| Driveway, walkways and patio | $299 to $350 | Whether walks and patio share the visit |

| House washing, single story | $299 to $350 | Especially wall area and siding type |
| House washing, two story | $350 to $500 | Particularly height and ladder access |
| Roof cleaning, composition | $300 to $600 | Pitch, and also moss build-up |
| Roof cleaning, cedar shake | $500 to $900 | Shake condition and roof size |
| Gutter cleaning, single story | $299 | Roofline length, including debris load |
| Gutter cleaning, two story | $299 | Height and access |
| Window cleaning | $299 to $700 | House size, including the number of stories |
| Skylights | $25 to $35 each | Roof access |
| Commercial storefront | $299 to $600 | Frontage length and foot traffic |
The bundle discount is 10% to 25% off when one booking combines several services. More services therefore earn a bigger share. An accepted figure stays the figure, with no add-ons even when the crew is on site. Job-by-job detail on each band lives in the Oregon cost guide. Ask us about the bundle when you book three or more services.
From first call to photos: a GreenTree job, step by step
Five stages, always in the same order, whether on a Corvallis driveway or a Portland storefront.
Ask for a price
Phone (971) 280-2861 during business hours, or use the online form instead.
Photos first, visit if needed
Many drives and one-level houses price from pictures alone, since the surfaces are simple. Steep or large jobs, however, get a site visit.
Written price
Each surface gets its own line and figure, and the figure you accept holds on the day.
Clean by surface
Plants get cover before anything else. The crew then sets the pressure for each material and steers the rinse onto soil.
Walk-through and photos
You walk the result with the crew, then receive a before-and-after pair for every surface.
Cash, check or credit card then settles the bill.
Who should call GreenTree, and who should call someone else?
Call GreenTree when a sound surface is dirty, green or stained and needs a method matched to its material. A failed surface, however, is a different story. Soft deck boards, lifted shingles, split gutter seams and cracked slabs need a repair trade before anything else. Cleaning can then follow once the repair holds.
Owners GreenTree tends to suit
- Sellers who want the outside clean before listing photos go up, through the pre-sale cleaning service.
- HOA boards and landlords, since each building gets its own written scope through the property manager page.
- Shop and office owners who want frontage washed around opening hours.
- Homeowners with a mossy shingle roof who want no pressure washer anywhere near it.
Requests that belong with someone else
- A small patio alone can fall under the job minimum, so pair it with a drive.
- Any repair, from a sagging gutter run to rotten fascia, needs its own trade before cleaning starts.
- Interior cleaning, carpets and interior walls sit outside what GreenTree does. Interior window glass is the one exception.
If you are unsure whether a job suits us, ask about it on the phone first.
Item by item: what the free quote checks at your address
A price written without these checks would be a guess, so the walkthrough covers each one. Each item below changes either the method or the figure.
- Material: the crew identifies each surface first, because the material decides the pressure and the product.
- Condition: loose paint, soft boards or lifted shingles change the plan, or stop it.
- Size: square footage of slabs and walls, plus the length of the roofline.
- Height and access: stories, roof pitch and the spots where a ladder can stand safely.
- Growth: a thin film of algae rinses off faster than thick, old moss, which takes more hand work.
- Stains: oil, rust and leaf tannin, some of which may only fade rather than vanish.
- Water: an outdoor tap with enough flow, since the machine draws on it all visit.
- Rinse route: where the water can soak in, and also where the nearest storm drain sits.
- Parking: room for the work vehicle close to the surfaces on the quote.
How can you verify GreenTree Services yourself?
You can verify GreenTree Services with three free checks before you book anything. First, type 2424331-91 into the state business registry search. Next, ask for the insurance certificate, which GreenTree sends before the visit. Then match the phone number and address on your quote to this page.
- Open the Oregon Secretary of State Find a Business page. It asks you to enter a business name or business registry number.
- Type 2424331-91 rather than the name. Before showing results, the state site may ask you to copy characters from an image.
- After that, compare the name on the record with the name on your quote. Names alone can match more than one firm, so the number is the safer search.
- Also ask for the insurance certificate, and read the limits on it. Look for $2 million of liability cover and a workers compensation line.
- Read the customer reviews on the live profile yourself, rather than trusting a figure quoted anywhere else.
The checklist for choosing an exterior cleaner turns these steps into questions for every firm you call, GreenTree included. Nothing about us should rest on trust alone, which is why these checks come first.

Ten answers about GreenTree Services
Short answers about us: the office, the paperwork and the limits of the work.
Where is the GreenTree Services office?
It sits at number 1460 on NW Van Buren Ave, in Corvallis. Call (971) 280-2861 between 7am and 7pm, any day of the week.
Is GreenTree Services the same business as other firms called Green Tree?
Not necessarily. Names alone can match more than one firm, so search by number instead. GreenTree Services in Corvallis holds Oregon Registry #2424331-91, because a registry number points to one business.
What kind of registration does GreenTree hold?
Entry 2424331-91 in the state business registry belongs to GreenTree. Still, it does not double as a construction contractor license. So repair work that needs a licensed trade goes to one.
Can I get proof of insurance before the crew arrives?
Yes. Request it when you accept the quote, and it arrives ahead of the crew. You will see the $2 million liability limit on it, next to the workers compensation policy.
What payment does GreenTree accept?
Cash, check and credit card all work. The amount matches the written figure you accepted, because that figure does not change on the day.
What water does GreenTree pressure wash with?
Cold water, plus a degreaser when oil or grease shows up. Siding and roofs get low pressure, while bare concrete takes the full force of the machine.
Does GreenTree clean commercial buildings as well as homes?
Yes. Storefronts, offices, apartment sites and HOA grounds all qualify, each with a written scope before work begins. A storefront wash runs $299 to $600, while multi-story commercial buildings run $400 to $900.
Which towns does GreenTree cover outside Corvallis?
Albany, Lebanon, Philomath, Salem, Eugene and Springfield in the valley, plus the Portland metro. In the metro, separate pages also serve Portland, Beaverton, Hillsboro, Tigard, Lake Oswego and Gresham.
Will GreenTree repair damage it spots during a clean?
No. GreenTree cleans, then points you to the right trade. A lifted shingle goes to a licensed roofer, and a split gutter to a gutter contractor. GreenTree, similarly, handles soft deck boards itself.
Is there a discount for booking several services at once?
Yes. Booking several services together earns 10% to 25% off, and the share grows with the number of services. Pairing a roof clean with the gutters, for example, qualifies.
