Tree Service & Arborist Business Insurance

Protecting crews, clients, and high-severity aerial operations

Tree service and arborist contractors prune, remove, and manage trees — climbing and aerial-lift work, chainsaw and chipper operation, large-limb and whole-tree removal over houses, cars, and power lines. The signature exposures are the ones gravity creates: a limb or a felled tree that lands where it was not supposed to, and a climber or lift operator who falls. These are among the most severe losses in any trade, which is why workers' compensation and the felled-tree property claim sit at the center of the program. This is a corner of contractor insurance built for how tree services actually get sued.

Properly structured coverage protects the crew, the client's property, the equipment, and the business behind every cut.

The Arborist's Signature Exposures

The defining exposure is the struck-by and falling-object loss — a cut limb, a rigged section, or a whole tree that falls onto a roof, vehicle, fence, or person, including the tree that goes the wrong way during a technical removal. Running alongside it is the fall exposure: climbers working at height on ropes and spikes, and operators in aerial lifts and bucket trucks, face catastrophic injury, and the resulting workers' compensation is the most severe line in the account. Chippers and stump grinders add amputation and projectile risk, work near energized lines adds electrocution exposure, and heavy trucks and loaded chip bodies add auto severity.

Key Risks in Tree Service Operations

Tree service and arborist contractors face exposure related to:

A cut limb or rigged section falling onto a structure, vehicle, or person below

A felled tree landing in an unintended direction and crushing property

Climber and aerial-lift falls producing catastrophic worker injuries

Chipper and stump-grinder amputations and thrown debris

Contact with or proximity to energized power lines

Underground utility damage during stump grinding and root work

Auto losses involving heavy trucks and loaded chip and log trailers

The falling limb or tree and the climber fall are what most define the tree service.

Core Coverages for Tree Service Contractors

A properly built tree service program typically includes:

Workers' Compensation — Provides legally required coverage for climbers, ground crew, and operators in an extreme-hazard trade — the single most important and most expensive line.

General Liability — Covers third-party bodily injury and property damage, including the felled-tree-on-a-structure claim that defines the trade.

Contractors Equipment / Inland Marine — Covers chippers, aerial lifts, bucket trucks, grinders, rigging, and climbing gear against theft and damage on site and in transit.

Commercial Auto — Covers trucks, chip bodies, and log and equipment trailers, with hired and non-owned auto for rented units.

Products & Completed Operations — Responds when a pruned, cabled, or treated tree later fails and causes injury or damage after the crew leaves.

Pollution Liability — Addresses herbicide, insecticide, and growth-regulator treatments and improper debris or waste disposal.

Umbrella / Excess Liability — Adds the higher limits a felled-tree catastrophe or a worker fall demands above the primary program.

Debris Removal & Emergency Storm Work — Supports the high-exposure after-hours removal and cleanup work that spikes during storm season.

What's Commonly Overlooked

Tree service programs are most often weakened by:

Workers' compensation limits or class codes that understate the aerial-fall exposure

High-value chippers, lifts, and bucket trucks left off or under-scheduled on inland marine

General liability limits too low for removals over occupied structures

No pollution coverage for the chemical treatment side of arbor care

Subcontractors on large or technical removals neither insured nor confirmed

The gap that hurts most is understated workers' compensation and equipment coverage for the fall and felled-tree exposures that define the work.

Real-World Claim Examples

A climber falls during a removal and sustains catastrophic injuries

A felled tree or rigged limb lands on a client's roof or a parked vehicle

A chipper accident causes a serious ground-crew injury

Stump grinding severs an underground utility or irrigation line

A limb removal near energized lines results in contact and injury

Any one of these can be catastrophic, and the fall and felled-tree claims are the most distinctive.

Regulatory & Safety Context

OSHA governs tree work directly — fall protection and climbing systems, aerial-lift and bucket-truck operation, chipper machine-guarding, and the electrical-safety rules that keep unqualified crews a minimum approach distance from energized lines. The ANSI A300 standards define proper tree-care practices and the ANSI Z133 standard sets the arboricultural safety requirements that insurers and courts treat as the benchmark for the trade. The EPA's FIFRA framework and state applicator licensing govern any chemical treatment, and state contractor or arborist licensing applies in many jurisdictions. Documented fall-protection and Z133 compliance is both a legal duty and an underwriting condition.

Why Proper Placement Matters

Underwriters weigh payroll and receipts, the share of removal versus pruning and maintenance, maximum working height, use of climbers versus lifts, work near power lines and over structures, crane use, equipment values, subcontractor use, and loss history — and prior claims weigh heavily in this class. Light pruning and maintenance accounts can place in the admitted market, but large removals, crane work, high climbing exposure, or a claims history commonly push the account to the excess and surplus market with higher deductibles and safety warranties. Presenting the work mix and the Z133 safety program accurately is what keeps the coverage available.

Our Approach

At Cory Washington & Co., we build tree service and arborist programs around the two exposures the trade is sued over — the fall and the falling tree. We lead with properly coded and adequately limited workers' compensation, size general liability and umbrella for removals over occupied structures, fully schedule chippers, lifts, and bucket trucks on inland marine, and add auto, completed operations, and pollution for the chemical side. We also insure related trades, including landscaping and lawn care.

Gravity decides where the limb lands and whether the climber falls — we build coverage for the day it goes wrong.
