Tree Ninjas operates out of Cherry Valley Road in Duvall — the middle of the valley, not a call center somewhere routing work to whoever answers. We’ve been working this corridor long enough to know which communities have permit requirements most crews haven’t heard of, where PSE’s distribution lines run through back properties, and how a Douglas fir in Cherry Valley’s alluvial soils behaves differently from one on a well-drained Redmond lot.

The work covers everything from single-tree removal to land clearing: tree removal and emergency response, trimming and pruning, stump grinding, hedge trimming, and certified arborist services including written hazard assessments and arborist reports. For the removal side specifically, see our tree removal guide for the Duvall area.

Are You Licensed, Insured, and ISA-Certified?

Tree Ninjas is licensed, bonded, and insured, with ISA Certified Arborists on staff. Here’s what that actually means rather than the standard marketing version.

The Washington contractor license is table stakes — any legitimate tree company has one, and you can verify it through L&I at lni.wa.gov/licensing-permits/contractors. The insurance question is the one most homeowners skip, and it matters more. We carry both general liability and workers’ compensation. The workers’ comp piece is the one that affects you: if a crew member without workers’ comp gets hurt on your property, you can end up in the middle of a claim. Ask for the certificate of insurance — not just their word that they have it — before anyone starts work.

ISA certification is worth understanding on its own terms. “Arborist” isn’t a protected term in Washington; anyone can put it on their truck. The ISA Certified Arborist credential requires passing a serious exam and keeping up with continuing education. For structural work, hazard assessments, and written documentation for permits or insurance claims, that credential is what you’re actually looking for.

Do You Offer Free Tree Service Estimates?

Yes, and we do them in person rather than over the phone. That’s not a formality — a tree that looks routine from a photo can turn into a different conversation once we see it’s hanging over the garage with the only access through a soft section of lawn. We’d rather give you the accurate number before we start than talk about surprises after.

We walk the property with you, go through each tree or area of work, and give you a written scope and price. No pressure, no obligation. We’re typically available for visits within two to four business days. If something is pressing, we can usually move faster.

How Soon Can You Come Out for a Tree Job?

For actual emergencies — tree on a structure, partially uprooted tree leaning on a building, a widow-maker hanging above where people move — we respond same-day or within hours depending on where the crew is. That’s what 24/7 means in practice.

For everything else: estimate visits within two to four business days, jobs typically scheduled within one to two weeks of the estimate. October is our busiest month — everyone wants pre-storm work done before November, and for good reason. If you call in late October with something non-urgent, the wait might run to three weeks. The better move is to call in September.

If you’re watching a tree and something looks off, call before it becomes the 3am version of the problem. We can tell you over the phone whether what you’re describing needs immediate attention or whether there’s time to schedule it properly.

Do You Offer Emergency Tree Service?

Yes — 24/7, throughout the Snoqualmie Valley and into King and Snohomish Counties.

What counts as an emergency:

• A tree or major limb has fallen on a structure, vehicle, or blocking access

• A partially failed tree is loading a roofline or structural element

• A tree has uprooted or cracked after a storm and poses immediate hazard

• A widow-maker is hanging in the canopy above an occupied area

What to do:

• If there’s any chance the tree or debris is near a power line: call 911 first; stay 30 feet away

• If a tree has come down on a structure: get people out, cover openings to keep weather out, and call us; don’t cut sections off a tree that’s loading a roof — each cut changes the forces

• Call Tree Ninjas at (206) 601-9390 for all other structural emergencies

The Snoqualmie Valley’s saturated soils and Cascade gap winds are a specific combination. Trees that have stood for decades can uproot in a single wind event when the ground is saturated. Getting ahead of that in September is worth it.

How to Choose a Tree Service Near You

The honest version isn’t complicated.

Start with the certificate of insurance. Ask for the actual document showing both general liability and workers’ comp — not just their word that they’re covered. A company operating properly sends it without a second thought. Hesitation is information.

Ask whether they have ISA Certified Arborists on staff, not just arborists. In Washington, anyone can use that title. ISA certification is verifiable. For structural decisions and anything that requires a written report, you want the credential.

Don’t accept a phone quote for removal or structural work. The variables that change a job’s cost — tree height, access, proximity to structures, ground conditions — require an in-person visit. A firm phone price either has a large uncertainty buffer built in, or it will shift when the crew arrives.

Ask about their approach to topping. Any crew that suggests topping as a solution for size or hazard isn’t following ISA standards, and the tree will show that over the next few years. Proper crown reduction achieves size reduction through lateral cuts without the stub decay and watersprout regrowth that topping causes.

Hiring local matters more in tree work than most trades, because the relevant knowledge is genuinely local. Permit rules in Duvall are different from unincorporated King County. PSE’s corridor has specific requirements that aren’t obvious from a map. The structural behavior of Douglas fir in Cherry Valley’s alluvial soils isn’t something you read about — it’s something you know from working here.
