These Google reviews of GreenTree Services appear exactly as customers wrote them, each under the first name and initial they used. This page states no rating and no review count. The live Google profile shows both, and those numbers change as new reviews arrive. Below the quotes, a short guide explains what a review can prove about exterior cleaning, and what it cannot.
Every quote and source link here matches its source as of 1 October 2026.

First, three short answers explain where the reviews live, why no numbers appear here and how to add your own. The GreenTree home page lists every service the quotes mention.
The full, current set of GreenTree Services reviews lives on the Google profile. In contrast, this page quotes a selection, word for word, and links each quote to the matching service. It does not repeat a rating or a count, because those change. Open the profile to read every review in full, including any critical ones.
Check the live Google profile, because this page deliberately prints neither number. Counts and ratings move whenever a new review arrives. A figure copied onto a website therefore goes stale, and a stale figure misleads. The profile link sits beside the quotes below, so you can check the current numbers yourself.
First, open the GreenTree Services profile on Google Maps, where all reviews sit, and choose the option to write a review. You need a Google account to post one. After that, describe the surface, the result and anything that went wrong. Specific details help the next reader far more than a rating alone.
Nine customers, quoted exactly, with spelling and punctuation left alone. Each card also names the service its quote describes, where the quote names one. Read every review, including the newest, on the GreenTree Services Google profile.
My driveway and back patio had not been cleaned in years. Both were so bad they looked black. By the time Green Tree was done both looked almost brand new. I would highly recommend and will use them again in the future.Diane M.
Named in the quote: Driveway and patio cleaning
We used GreenTree to wash all our exterior windows and clean our skylights and gutters. They were super congenial, professional and had excellent communication. They did a great job and I trusted them. I really like supporting businesses like this!Susan A.
Services she names: Window and skylight cleaning and Gutter cleaning

By contrast, these six quotes praise the crew or the company without naming a surface. For that reason, they link to no single service page. The services overview lists every service instead.

Read for specifics: the surface, the problem, the method and how the result held up. For example, a review that names a driveway, a mossy roof or blocked gutters tells you something checkable. By contrast, praise with no detail tells you about mood, not method. Weigh several sources instead of just one.
The FTC guide to evaluating online reviews offers a few habits worth borrowing. For instance, it suggests checking how recent reviews are, and watching for a burst over a short period. It also suggests reading the other reviews a reviewer has written, if any exist. And it warns that you cannot always spot a fake review just by looking.
A review written on the day says nothing about how the surface ages over the next year. It also rarely says what pressure the crew used, or where the rinse water ran. Nor can it show harm that appears months later, such as shingle granule loss or water behind siding. Those risks sit in the method, so check the method separately.
Some praise describes the very thing a manufacturer warns against. Note, though, that the phrases below are examples written for this guide, not real reviews.
| Example phrase, not a real review | Why it should worry you | Where the warning comes from |
|---|---|---|
| They blasted the moss right off my roof | Pressure on asphalt shingles strips the protective granules | ARMA roof cleaning guidance |
| They hit our fiber cement siding hard | James Hardie advises a soft brush and a garden hose instead | James Hardie siding care |
| They sprayed right up under the vinyl laps | An upward stream can push water behind the panels | Vinyl siding trade association care guide |
| Our gray deck came up bright with raised, ridged grain | Ridged, raised grain can signal aggressive power washing | FPL Wood Handbook, chapter 16 |
| The old brick path looks smooth and brand new | High-pressure water can abrade the face of old brick | NPS guide to cleaning masonry |
None of these example phrases appears in the GreenTree quotes above. Still, phrases like them can turn up in reviews of any company, so read closely.
Check three things yourself: the state business record, the insurance certificate and the written quote. Reviews describe experiences, while these documents describe obligations. Also, each check takes a few minutes, and none depends on what a company says about itself. Run the same three checks on GreenTree too.
The Oregon Secretary of State business registry search accepts a business name or a registry number. GreenTree Services appears there under Registry #2424331-91. A registry entry is proof of registration, not a trade license. The same search also finds the registered agent, the person who receives legal papers.
First, ask for a certificate of insurance before work starts, whoever you hire. Read the policy dates first, then the liability limit and the name of the insurer. Call that insurer afterwards to confirm the policy is active. The figure to look for on a GreenTree certificate is $2 million of general liability. Workers compensation cover sits alongside it.
Above all, a written quote turns a spoken promise into a document you can hold. Check, therefore, that it names each surface, its price and anything left out. GreenTree writes its price down and holds it once you say yes.
| Check | Where to do it | What it shows |
|---|---|---|
| Business registration | The state business name search, online | A registered business with a named agent |
| Insurance | A certificate from the contractor, confirmed by the insurer | Cover that is active on the day of your job |
| Written quote | From the contractor, before any work starts | The price and scope you agreed to |
| Reviews | The Google profile and other review sites | Their experience of earlier jobs |
| Method | Your own questions, asked at the quote visit | Pressure, cleaning products and run-off for your surface |
A Federal Trade Commission rule, announced in August 2024, bans fake reviews and testimonials. It lets the agency seek civil penalties against knowing violators. Under the rule, a fake review means one from someone who does not exist or never used the business. It also bars rewards tied to reviews that must sound positive or negative.
The FTC announcement of the final rule lists other banned practices too. A business may not post insider reviews that lack a clear disclosure. Likewise, it may not use groundless legal threats or intimidation to remove a negative review. Nor may it claim its review section shows all or most reviews after suppressing negative ones.
That last point shapes this page. After all, the quotes here are a selection, and the Google profile holds the full public record. So read both, rather than trusting either one alone.
Five checks work for any contractor, GreenTree included.
Read the reviews for specifics
Note which surfaces customers mention and what went right or wrong. Skip praise that names nothing at all.
Find the state record
Type the company name into the Oregon Secretary of State search. Check that the number matches the one the company gave you.
Request the insurance certificate
Ask for it before booking, then call the insurer named on it. Check that the dates cover your job.
Insist on a written price
Each surface should carry its own line and figure. Also ask what falls outside it.
Ask about the method
Ask what pressure each surface gets and where the rinse water goes. Clear answers matter more than any rating.
Keep notes as you go, because the answers are easy to mix up between companies. When two contractors pass every check, the written quotes usually settle the choice.
Hire a different trade when the job is repair, installation or interior work. GreenTree cleans exteriors: driveways, patios, siding, roofs, gutters, decks, fences and windows. Roof repair goes to a licensed roofer, while gutter guards go to an installer. The same goes for indoor cleaning, painting and tree removal.
Overall, the quotes here suit anyone weighing exterior cleaning in the Willamette Valley or the Portland metro. They describe cleaning, so they tell you nothing about repair work, which GreenTree does not do.
Reviews tell you how past jobs felt, while the free quote tells you what yours will involve. Here is what the free quote checks.
The free quote checks the surface first: its material, its condition and what grows on it. After that come size, access and the height of the work. Finally, a water supply, the path for run-off and a place to park round it out. Then compare that list with what reviewers mention, and any gaps show up fast.
Request the quote through the free quote page. The phone line, (971) 280-2861, is answered 7 days a week, 7am to 7pm.
These answers cover ratings, editing, fake reviews and the records you can check yourself.
Ratings change with every new review, so a copied figure soon goes stale. The live Google profile always shows the current one.
No. Each quote keeps its original wording, spelling and punctuation. Only the cards, headings and links around the quotes are ours.
Some customers wrote about the company as a whole. Those cards say so, instead of guessing which job the words describe.
Not under the FTC rule announced in August 2024. It bars rewards that depend on a review expressing a particular sentiment.
Often you cannot, and the FTC itself says so. Still, check the timing, the reviewer history and whether the details hang together.
It shows GreenTree Services holds an Oregon business registration. That is a business record, not a trade license.
Ask for the certificate, then phone the insurer named on it. The general liability limit on it should read $2 million.
Not by itself. Length helps only when it adds specifics, such as the surface, the method or the final bill.
It sits on Google Maps under the name GreenTree Services. The profile link on this page opens it directly.
Yes. Google takes reviews at any rating, and an honest critical review helps the next buyer more than silence does.
Start with the registry search and the Google profile. Then ask for a written quote, and hold it up against what reviewers describe.
