What an Arborist Assessment Covers
An arborist consultation is a professional evaluation of your tree's health, structure, and risk — the step that should come before you spend money on major work. During an assessment, a qualified tree care professional examines the canopy for dieback and abnormal growth, inspects the trunk for cracks, cavities, and decay, evaluates the root zone for damage or disease, and considers the tree's surroundings: lean, targets like your home or driveway, and site conditions like drainage and soil compaction. You get a plain-English explanation of what we found and what we recommend — pruning, monitoring, treatment of correctable issues, or removal when the tree truly can't be saved.
Health Assessments
Thinning canopy, discolored leaves, dead branches, fungal growth at the base — we diagnose what's ailing your tree and whether it's correctable.
Risk Evaluations
Leaning trees, cracked trunks, storm damage, and root failure get a structured risk assessment so you know the real level of hazard — not a guess.
Second Opinions
Been told a tree must come down? A second opinion is cheap insurance. We've saved plenty of trees that were condemned a little too quickly.
When To Call an Arborist
- Visible decline. Dieback in the crown, early leaf drop, or mushrooms growing on the trunk or root flare warrant a professional look.
- After storm damage. A tree that lost major limbs or shifted in its root plate needs evaluation before the next storm tests it.
- Before construction. Building an addition, ADU, pool, or driveway near mature trees? A preservation plan protects roots during construction and avoids killing a tree you wanted to keep.
- Leaning or cracked trees. New leans, trunk cracks, or lifted soil on one side are risk factors that deserve expert judgment.
- Before removing a valuable tree. Heritage oaks and mature specimen trees add real property value — confirm removal is necessary before it's gone forever.
- Permit and HOA paperwork. Many cities and HOAs want a professional assessment before approving tree work on protected trees.
Construction preservation planning: most tree damage during construction happens underground, where grading and trenching sever roots. We establish protection zones, recommend root-friendly construction practices, and monitor the tree — so your project doesn't become a removal a year later.
Disease & Pest Diagnosis — Honest Answers
We diagnose common tree health problems seen across Santa Clara County — fungal decay, boring insects, and cultural issues like overwatering, compacted soil, and improper pruning. We'll tell you straight when a problem is treatable and when it isn't: early-stage issues often respond to corrective pruning and improved growing conditions, while advanced trunk decay or severe root damage generally can't be reversed. We don't sell miracle cures or make treatment promises we can't keep. If the honest answer is removal, we'll explain why — and if the tree can be saved, we'll show you the plan.

Frequently Asked Questions
What happens during an arborist assessment?
A qualified tree care professional visits your property, examines the tree's canopy, trunk, and root zone, and evaluates its health, structure, and risk factors. You receive a clear explanation of what's wrong — if anything — and recommended next steps, such as pruning, treatment, or removal.
When should I get an arborist assessment?
Get an assessment when a tree shows signs of decline, after storm damage, before construction near mature trees, when a tree leans or cracks, or before removing a large or valuable tree — a second opinion can save a tree worth keeping.
How much does an arborist consultation cost?
Consultation pricing varies with the number of trees and the depth of the report needed. Many assessments tied to planned tree work are provided as part of a free estimate. Send the quote form to discuss your situation and we'll quote the consultation upfront.
Can a sick tree be saved?
Sometimes. Early-stage issues — correctable pruning problems, minor pest pressure, or cultural stress like overwatering — often respond well to intervention. Advanced trunk decay or severe root damage usually cannot be reversed. An assessment tells you honestly which situation you're in.
Do you provide written reports for permits or insurance?
Yes. We can document our findings in writing for permit applications, insurance claims, or HOA approvals — including the tree's condition, our recommendations, and supporting photos.
