Who Needs This Service

🏡

Homeowners with Older Trees

Trees over 40–50 years old, leaning trees, trees near your home, or trees with visible damage warrant professional evaluation.

🏠

Home Buyers & Real Estate Agents

Before purchasing property with mature trees, an assessment identifies potential liabilities and remediation costs.

⚠️

Storm Damage Situations

After a storm or when you notice dead branches, broken limbs, or uprooted trees, a formal assessment guides next steps.

🏗️

Construction & Renovation Projects

If you're building, remodeling, or significantly grading around trees, an assessment protects valuable trees and documents baseline conditions.

🛡️

Insurance & Legal Protection

If you've received a tree-related insurance claim, faced a lawsuit, or need documentation for a permit, a professional assessment supports your position.

🌳

Property Managers & Developers

Regular assessments of landscape trees on commercial or multi-family properties reduce liability and identify maintenance priorities.

The Assessment Process

Request

Fill out the form or call. Provide your address and describe the trees you're concerned about — age, size, condition, or specific concerns.

3

Evaluate

An ISA Certified Arborist visits your property, inspects all trees, documents findings, and takes photos of significant defects or hazards.

4

Report

You receive a written report (typically 3–5 business days) with detailed findings, risk ratings, and specific recommendations for each tree.

5

Follow-Up

We're available by phone or email to discuss the report, answer questions, and help you understand next steps and priorities.

Common Questions

An ISA Certified Arborist visits your property and performs a comprehensive evaluation of each tree's structural integrity, health, and proximity to buildings, utilities, and people. We assess hazards using ISA methodology, evaluate the likelihood of failure, identify consequences, and assign a risk rating. You receive a detailed written report outlining findings and recommended actions.

Tree risk assessments range from $300–$600 depending on the number of trees, property size, and complexity. Most residential properties with 3–8 trees fall in the $400–$550 range. We provide a price estimate before scheduling. Turnaround is typically 3–5 business days.

Get an assessment if you notice leaning trees, large dead branches, proximity of trees to your home, after a storm, before purchasing property with mature trees, or if your insurance company requires one. If a tree is actively dangerous (partially uprooted, large hanging branches), contact a tree service immediately rather than waiting for an assessment.

If removal is recommended, the assessment report provides a clear explanation of why. You can then get quotes from vetted tree services. We can help you understand which recommendations are urgent versus long-term, and can review tree service quotes to ensure the scope matches the risk level.

Not exactly. A tree risk assessment focuses on hazard evaluation and mitigation. An insurance or legal report is more detailed, documented for third-party use, and often requires specific formats. If you need an assessment with formal documentation for insurance or legal purposes, specify that when requesting the service.

An assessment evaluates the probability of failure and the likely consequences if failure occurs. No assessment can predict with 100% certainty whether a tree will fail — trees are living organisms. A formal assessment reduces uncertainty by identifying visible structural defects and hazards that warrant action.

A tree risk assessment report can support permit applications, especially for protected tree removal where you must document a legitimate hazard. Some municipalities have specific format requirements — let us know if you need the report formatted for a specific city's permit process.
