Lewis-Clark Valley Tree Service
Lewiston Tree Service in Idaho, Clarkston, and Asotin
Lewiston tree service on both sides of the Snake: Lewiston and the Orchards in Idaho, Clarkston and Asotin in Washington. Lewiston Tree Pros connects you with licensed, insured local crews for trimming, stump grinding, storm cleanup, and the occasional takedown, matched to the state the property sits in.
What Lewiston tree service covers in this valley
Lewiston Tree Pros connects property owners with licensed, insured local tree crews serving both sides of the Lewis-Clark Valley: Lewiston and the Orchards in Idaho, and Clarkston and Asotin in Washington, sitting across the Snake River from each other where the Clearwater River joins in. This is one valley market with basalt canyon walls rising on both flanks, hot dry summers, and a mix of mature street trees, orchard-era fruit trees, and native conifer that behaves differently depending on the block. Whether the job is tree removal in Lewiston ID, seasonal trimming ahead of a storm, stump grinding after a previous removal, or cleanup once wind has already brought a tree down, Lewiston Tree Pros gets the details of the job and connects the property owner with a crew licensed to work on the correct side of the state line.

Why Trees Fail in This Valley
Lewiston sits at roughly 738 to 741 feet elevation, near the lowest point in Idaho, where the Clearwater River meets the Snake. That low elevation brings a semi-arid climate: a July average near 76 degrees, about 42 days a year at 90 degrees or above, and roughly a week each summer at 100 degrees or higher. Heat and dry soil stress trees that were not built for this valley's conditions, and two species show up again and again in failure calls. Siberian elm is a fast-growing species that tolerates disturbed, dry ground but forms brittle wood and weak branch unions that split in wind or heavy snow. Black locust is similarly brittle and decay-prone, with aggressive root suckering and thorny regrowth after cutting. Ponderosa pine, by contrast, is native to the dry canyon rims and uplands surrounding the valley and generally holds up better, though it is less common on the valley floor itself, where plantings lean toward a mixed urban palette rather than native forest. Knowing which species is actually on a property changes how a crew plans the work.

Two-State Coverage
Serving Both Sides of the River
Idaho and Washington do not regulate tree work the same way, and that difference matters for anyone hiring a crew in this valley. Washington's RCW 18.27 explicitly names tree removal as regulated contractor work, requiring registration, a bond, and liability coverage before a crew can advertise or work anywhere in the state, including Asotin County and Clarkston. Idaho regulates construction contractors more broadly through the Idaho Contractor Registration Act, and its rules do not separately call out tree service one way or the other, a real gray area rather than a clean parallel to Washington's rule. Lewiston Tree Pros connects property owners with crews that carry the coverage appropriate to whichever side of the river the job sits on. See the about page for more on how that connection works, and the tree removal page for the fuller two-state breakdown.
Coverage
Where We Cover
Lewiston Tree Pros covers the full valley floor and the terrain rising above it: downtown Lewiston, the Lewiston Orchards bench, Clarkston and Asotin across the river in Washington, and Lapwai to the south, home of the Nez Perce Tribe's headquarters. Nearby unincorporated communities in Nez Perce and Asotin counties are welcome to call as well. See the full service area breakdown for a town-by-town look at terrain, access, and what each area's tree stock tends to look like.
FAQ
Common Questions
What does Lewiston tree service actually cover?
Lewiston tree service here means the full valley job mix: trimming and pruning, stump grinding, storm cleanup, and takedowns when a tree is past saving. Lewiston Tree Pros connects Lewiston, Clarkston, and Asotin property owners with licensed local crews for the work that fits the lot, the species, and the state line the property sits on.
Do you serve Clarkston and Asotin, or only Lewiston?
Both sides of the river. Lewiston and the Orchards sit in Idaho. Clarkston and Asotin sit in Washington, a few minutes across the Snake. This is one valley market. We connect you with a crew licensed for the state the property is in, including Asotin County lots on the Washington side and Nez Perce County lots on the Idaho side.
Who actually does the work when I call?
You reach Lewiston Tree Pros, a locally operated service brand, not an in-house climbing crew with a shop yard. We take the details of the tree, the lot, and which side of the river you are on, then connect you with a licensed, insured local crew that can do the job. Timing follows that crew's schedule, not a promise.
Is tree work licensed the same in Idaho and Washington?
No. Washington's RCW 18.27 names tree removal as regulated contractor work, so a crew needs registration, bonding, and insurance before working in Clarkston or Asotin. Idaho uses the broader Contractor Registration Act and does not separately call out tree service. Crews we connect you with carry coverage for the state the job is in.
Which trees fail most often in this valley?
Siberian elm and black locust show up often in failure calls on the valley floor. Both tolerate dry, disturbed ground, then split in wind or heavy wet snow because the wood is brittle and the unions are weak. Ponderosa pine on the canyon rims holds up better. Knowing the species on a lot changes how a crew plans the work.
