Tree Trimming
Selective pruning for clearance, safety, and long-term tree health — not a hack-back that leaves stubs and invites disease.

Why trimming is more than a haircut for your tree
Every cut Kerry makes follows ANSI A300, the tree care industry's standard for pruning practices. That standard exists because bad pruning is worse than no pruning at all. A flush cut that slices into the branch collar — the slightly swollen ring of tissue where a limb meets the trunk — removes the tree's own defense mechanism against decay, opening a wound that can take years to close, if it closes at all. Topping a tree, or cutting main limbs back to stubs, does the same thing on a larger scale: it forces the tree to regrow from weak, poorly attached water sprouts that are more likely to fail in a future storm than the limb that was removed in the first place.
Done correctly, trimming does the opposite. Crown thinning reduces the sail area a tree presents to wind, lowering the odds it loses a limb — or comes down entirely — the next time a storm rolls through. Removing deadwood eliminates the branches most likely to drop without warning. Clearance pruning keeps growth off rooflines, siding, and power service drops before a wind event forces the issue. And on younger trees, structural pruning shapes strong, well-spaced scaffold limbs early, which is the cheapest insurance against expensive storm damage twenty years down the road.
There's a property and liability angle too. A tree that's grown unchecked into a neighbor's yard, over a driveway, or across a power line is a slow-motion liability claim waiting to happen. Regular trimming is the difference between staying ahead of that and paying for it later — either in tree removal, or in someone else's insurance claim.
How a professional trim actually gets done
Assess the tree, not just the branch
Kerry looks at species, age, structure, and what the trim is actually for — clearance, health, a sightline, or training a young tree — before a single cut is planned.
Decide how to reach the canopy
Some limbs are reachable from the ground. Most of the ones that actually matter for a tree's long-term health — deep crown thinning, deadwood high in the canopy, clearance near a second-story roofline — aren't. That's when Kerry climbs.
Make selective cuts at the branch collar
Every cut is placed to let the tree seal itself properly — no flush cuts, no stubs, no topping. Crown thinning, deadwood removal, and clearance pruning are all done as thinning cuts back to a healthy union.
Control where every piece lands
Limbs near a roof, a fence, or a garden bed get lowered on a line rather than dropped, so nothing damages what's underneath on the way down.
Clean up completely
Branches and brush get chipped and hauled off — no twigs left scattered across the lawn, no cleanup left for you.
Why this is a climbing job, not a pole-saw job
A pole saw or a pair of loafers and a ladder can reach maybe the bottom 12 to 15 feet of a mature tree. The cuts that actually shape a tree's long-term health and safety — deadwood buried deep in the canopy, clearance pruning 30 or 40 feet up near a second-story roofline, structural correction on a codominant leader — are well above that. Working from the ground on those cuts means guessing at where the branch collar is and hoping the angle is right; working from inside the canopy on a climbing line means Kerry can see the exact cut he's making before he makes it.
Terrain plays into it too. A lot of the service area — the steep, thin-soil lots climbing toward Roan Mountain, gorge-side properties in Erwin, narrow gravel drives around Mountain City — simply doesn't have room for a bucket truck to set up. Climbing isn't a fallback for those properties; it's the only access method that works at all, which is exactly why it's the company's core method everywhere, not just in the mountains.
Tree trimmers and pruners face a fatal injury rate of roughly 110 per 100,000 full-time workers — in the same tier as logging, and about 30 times the rate across all U.S. occupations, according to industry analysis of Bureau of Labor Statistics data. Working 40 feet up in a live canopy with a running chainsaw isn't a job for an unqualified ground crew or a DIY weekend project — it's why arborists train specifically in ANSI Z133, the safety standard covering climbing, rigging, and chainsaw use in tree care.
Trimming across the service area
Tree trimming is available anywhere The Tree Climber works, with technique adjusted for what's actually growing on your lot — lake-effect white pine in Hampton, decades-old oak and maple in Johnson City's older neighborhoods, wind-battered spruce and fir at elevation on Roan Mountain.

Tree trimming questions
How much of a tree can be trimmed at once without hurting it?
The industry guideline (ANSI A300, the tree care standard most reputable arborists work from) is to avoid removing more than about 25% of a tree's live crown in a single season, and often less on older or stressed trees. Taking more than that at once can shock the tree, trigger weak epicormic regrowth, or leave it without enough leaf area to feed its root system. Kerry plans multi-year trimming schedules for trees that need more correction than one visit should safely give them.
If you cut a branch, won't more branches just grow back right at the cut?
It depends on the cut. A 'heading cut' that shortens a branch mid-length does often trigger a cluster of weak, fast-growing sprouts right at the wound — that's the hack-back look you see after a bad trim job. A proper thinning cut removes the branch all the way back to its point of origin at the branch collar, which closes over cleanly instead of sprouting. Kerry uses thinning cuts almost exclusively, which is why a trim from The Tree Climber still looks like a tree afterward, not a stub farm.
Do you trim trees that are growing into power lines?
Kerry will handle clearance pruning that keeps a tree off your roof, siding, or a service drop coming into your own house. Primary distribution lines running down the street are a different story — those get left to the utility company's line-clearance crews, since cutting near an energized primary line requires specific utility certifications Kerry doesn't hold and shouldn't be pretending to. He'll tell you straight which situation you're in before any cut is made.
How often does a tree actually need to be trimmed?
For most established shade trees, every 3 to 5 years keeps deadwood and clearance issues from piling up. Younger trees benefit from a lighter structural trim every 1 to 2 years while they're still being trained toward a strong shape. Trees with a known weak spot — storm-damaged limbs, a crack, a lean that's changed — get looked at sooner regardless of schedule.
Does trimming require a bucket truck parked on my lawn?
No — Kerry climbs. That means no truck tires crossing wet grass, no boom swinging over a fence line, and no need for a flat staging area near the tree. It also means he can get to the exact branch that needs a cut instead of whatever the boom happens to reach.
