Common Tree Removal Scenarios
A dead tree is one that has stopped producing leaves and lost the structure that kept it standing — and in Portland, decaying wood becomes a liability in the city’s periodic windstorms. As the trunk and roots rot, the tree can fail with little warning.
Dead trees attract pests and spread wood-decay fungi to nearby healthy trees, dragging down both safety and curb appeal.
Note that Portland requires a removal permit for trees 12 inches in diameter or larger and mandates replanting. Monkeyman’s office team handles the Urban Forestry process so a dead tree is removed correctly and in compliance.
An overgrown tree is a healthy tree that has outgrown its space, pushing into rooflines, utilities, or a neighbor’s property. Portland’s tree-friendly climate pushes trees past their boundaries quickly.
When a tree threatens a structure or crosses a property line, the owner is responsible for safe removal, and roots can disturb foundations and sidewalks before the canopy looks like a problem.
Because the city protects its canopy, removing an overgrown tree 12″ DBH or larger requires a permit and replanting — Monkeyman’s manages both, and recommends pruning where it solves the issue.
A diseased tree carries an infection that weakens it from the inside, and it can look healthy while it’s hollow underneath. In Portland’s wet environment, root rot, heart rot, and Verticillium wilt are all common.
Heart rot in particular often goes unnoticed until a tree is already a removal candidate, and infections can spread to surrounding vegetation.
Monkeyman’s ISA Certified Arborists diagnose the disease, navigate the city’s permit and replanting requirements, and remove trees that can’t be saved — treating first whenever it’s viable.
A storm-damaged tree has been cracked, split, uprooted, or partly destroyed by wind, ice, or debris. Portland’s ice storms leave cracked, split, and leaning trees citywide.
As a guideline, more than 50% crown loss usually means removal, though a vigorous tree that kept its leader can often recover.
Importantly, Portland can require a permit even for storm-downed tree removal — including retroactively — so it’s wise to use a service that handles the Urban Forestry process for you. Monkeyman’s does exactly that.
Emergency tree removal is the 24/7 response needed when a tree has fallen, or is about to, onto a home, vehicle, road, or power line. These removals are dangerous and call for a careful, experienced crew.
For high-risk jobs, Monkeyman’s brings in a crane through our Smith Crane partnership to control the hazard and prevent sudden movement mid-cut.
When a tree falls on a Portland property, we respond day or night and manage the city’s emergency-removal permitting so the cleanup is handled correctly.
View clearing is the selective removal or pruning of trees blocking a scenic sightline. Portland’s hills offer some of the best views in the region, from the West Hills to the bluffs above the Willamette.
Because the obstructing trees usually grow on a slope below the view, the work is technical — and permit-sensitive given the city’s 12″ DBH threshold.
Monkeyman’s plans every cut to open your view while keeping you compliant with the city’s tree code and preserving the trees that anchor your landscape.
Lot clearing is the systematic removal of trees and vegetation to prepare a site for construction or grading. Portland’s infill development almost always starts with tree removal.
Larger jobs may use a track hoe or bulldozer, with trees removed in sections where they can’t be felled directly.
Because the city’s canopy rules and replanting requirements make compliance essential, Monkeyman’s clears residential and commercial lots and manages the permits and mitigation for you.

During an estimate we will review the tree that needs to be removed, the conditions of the terrain, the condition of the tree, the accessibility of the tree, the equipment that may or may not be needed, and the total price of the tree removal.
We can give you an estimate for the tree removal that includes debris removal or we can provide you with a tree removal estimate that allows you to care for the wood after the job is complete.
Yes.
We carry copies of our insurance and license on each tree removal job. However, the best way to verify whether a company has insurance, or not, is to call the insurance agent directly, or to request a copy that is made out to you with your name on it and the current date.
In any case, we are happy to provide you with a copy of our insurance coverage, bond, and Oregon or Washington Contractors license.

The cost of a tree removal depends on a number of factors, namely; the height of the tree, the risks involving the condition of the tree, the terrain, and the accessibility of the tree.
An 80 foot tree sandwiched between 2 multi-million dollar homes on a cliff side containing 18 bees nests is going to cost a bit more than a 10 foot apple tree in the middle of a field (and no bees nests).
The time in which it takes to remove a tree depends on many of the same conditions that determine the cost of a tree removal, like the height, conditions and accessibility of the tree.
Most average to small trees can be removed, chipped, and hauled away in 3-6 hours. Larger trees that require climbing, are hard to access, and are very large, may take a day or two. Either way, we will give you an estimated time before we begin work to make sure that we are all on the same page.
