Who Is GreenTree Services?
About GreenTree Services: we are a locally owned exterior cleaning company based at 1460 NW Vanburn Ave in Corvallis, Oregon. We started in 2022 with one truck, one pressure washer, and a commitment to doing the job right the first time. Today we serve five Willamette Valley cities with four core services, $2M liability coverage, and a 5.0 Google rating that we have maintained since day one.
GreenTree was built on a simple idea: Oregon homes need annual exterior cleaning, and most homeowners cannot find a company that is insured, reviewed, and willing to put its price in writing before starting work. So we built a business around all three. Every quote is free, measured by actual square footage, and locked in writing. The number on the estimate is the number on the invoice. No surprises. No add-ons. No “well, it turned out to be more than we thought.”
Our Base of Operations
We operate from Corvallis, which puts us within 50 minutes of every city we serve. Philomath is 2 miles away. Corvallis is home base. Albany is 15 minutes east. Eugene is 45 minutes south. And Springfield is 50 minutes. Then there are zero trip fees for any of these locations because they are all within our standard service area.
What We Do
Four core services cover every exterior surface on your home. Pressure washing cleans driveways, sidewalks, patios, and hardscapes at 3,000+ PSI. House washing uses soft wash at under 500 PSI for all siding types. Roof cleaning removes moss with maker-approved soft wash solutions. And gutter cleaning clears debris, flushes every downspout, and tests full drainage flow. Also, read our Soft Wash vs Pressure Wash Guide to understand which method your home needs.
Why Do Oregon Homeowners Trust GreenTree?
Three things set GreenTree apart from other Oregon exterior cleaning companies: $2M liability insurance on every job, a 5.0 Google rating across 47+ reviews that we have never dropped below, and our Triple Protection Guarantee that puts our money behind our promises. No other Willamette Valley cleaning company matches all three.
$2M General Liability Insurance
Our insurance covers your property from the moment we arrive until the moment we leave. So if our equipment damages a window, a plant, or a surface, our policy pays for the repair or replacement. Also, we carry this coverage on every job, not just the big ones. Then many Oregon cleaning companies operate with $500K or $1M coverage. But we doubled the standard because our clients’ homes are worth protecting at the highest level.
5.0 Google Rating Since 2022
We have maintained a perfect 5.0 across 47+ Google reviews since we started. So every single review is five stars. That does not happen by accident. It happens because we do not leave a property until the owner walks it with us and confirms they are satisfied. Also, if someone is not happy with any area, we re-clean it on the spot. Then we follow up the next day to make sure everything still looks right. Read our reviews on Google.
Triple Protection Guarantee
Every job includes three promises. First, satisfaction: not happy with any area, we re-clean it free with no questions and no expiration. Second, insurance: $2M coverage protects your property throughout the entire job. Third, price lock: the written estimate is the final price, period. Zero hidden fees. Zero “we found something extra.” Zero post-job adjustments. The number you approve is the number you pay.

Where Does GreenTree Provide Service in Oregon?
GreenTree serves the Willamette Valley from our Corvallis base. Our core service area covers five cities across three counties: Corvallis and Philomath in Benton County, Albany in Linn County, and Eugene and Springfield in Lane County. Then we also serve 15+ smaller communities within a 50-mile radius including Adair Village, Lebanon, Sweet Home, Junction City, Veneta, Harrisburg, Tangent, Millersburg, and Monroe.
Benton County: Corvallis and Philomath
Corvallis is home. So we know every neighborhood: Timberhill, College Hill, South Corvallis, Witham Hill, and the OSU campus area. We know which streets have the worst canopy shade, which driveways slope toward the house, and which rental blocks need turnover cleaning every September. Then Philomath is 2 miles west with heavier Coast Range rainfall and faster moss growth. ZIP codes served: 97330, 97331, 97333, 97370. Corvallis services | Philomath services
Linn County: Albany
Albany sits 15 minutes east at the Calapooia and Willamette River confluence. So dual-river humidity means faster exterior growth than single-river cities. Also, four historic districts have irreplaceable architectural details that need gentle cleaning. We serve North Albany, South Albany, Monteith District, and Hackleman District. ZIP codes: 97321, 97322. Albany services
Lane County: Eugene and Springfield
Eugene is 45 minutes south with Oregon’s densest urban tree canopy at 30%. So Fairmount, College Hill, South Eugene, Amazon, and West University face heavy biological growth on every surface. Then Springfield sits at the McKenzie-Willamette confluence with twin-river moisture in Gateway and Thurston. Both cities get full service at the same prices as Corvallis. ZIP codes: 97401-97405, 97477, 97478. Eugene services | Springfield services

How Is GreenTree Different From Other Oregon Cleaning Companies?
Most exterior cleaning companies in Oregon own one type of equipment and use it on everything. So pressure-only companies blast siding at dangerous PSI. And soft-wash-only companies leave embedded stains on concrete. GreenTree carries both systems on every truck because Oregon properties need both methods. We match the right technique to each surface on your property in a single visit.
We Assess Before We Clean
Every job starts with a free property walk. So our technician checks surface material, paint condition, mortar type, shingle age, and contamination level before any equipment comes off the truck. Then we create a zone-by-zone cleaning plan that assigns the right PSI, nozzle, and solution to each area. You approve the plan before we start. This prevents every type of cleaning damage that other companies cause by using one setting for everything. Read our Soft Wash vs Pressure Wash Guide for more on how we choose methods.
We Document Everything
Every job ends with before-and-after photos that we provide for your records. So these are valuable for insurance claims, property management files, and real estate listings. Also, if you ever need to prove ongoing roof upkeep to your insurer, our timestamped photos show exactly when the last cleaning happened. Then we follow up the next day to confirm satisfaction. This level of documentation is something most Oregon cleaning companies skip entirely.
We Use Eco-Safe Products
All GreenTree cleaning solutions are eco-safe and break down within 24 hours. So they are safe for Oregon waterways, pets, children, and landscaping. But they are strong enough to kill algae, mold, and mildew at the root. We pre-wet all plants before cleaning and rinse them with fresh water after. In thousands of jobs, we have zero plant damage incidents. Learn more from the EPA stormwater guidelines we follow.
