Tree Appraisal
Trees Have Real, Measurable Value — A Professional Appraisal Makes Sure That Value Is Properly Recognized
Why It Matters
Appraisals Conducted by a Board-Certified Master Arborist
A mature tree that has been growing on a property for thirty or forty years cannot simply be replaced with a nursery specimen. The shade it provides, the privacy it creates, the aesthetic character it gives a property, and the years of establishment it represents all contribute to a value that is far greater than the cost of a new planting.
Every tree appraisal we provide is conducted by Robert Apolinar, a Board-Certified Master Arborist, using the ISA's Guide for Plant Appraisal — the professional standard recognized by insurers, courts, and municipalities. An appraisal prepared by a Board-Certified Master Arborist carries significantly more weight than one prepared by someone without that credential.
When the valuation matters — in a legal matter, an insurance negotiation, or a property dispute — the qualification of the appraiser is part of what gives the document credibility.

What We Know
What Tree Appraisal Actually Measures
Trees contribute value to a property in ways that are easy to overlook until they're gone. A professional appraisal accounts for all of these factors to arrive at a valuation that reflects the tree's true worth — not a simple replacement cost estimate.
Beyond Replacement Cost
Shade that meaningfully reduces cooling costs, privacy screens and windbreaks that took decades to develop, and heritage specimens with distinct aesthetic character all contribute value that a simple nursery replacement cost cannot capture.
ISA-Standard Methodology
Appraisal values are calculated using the ISA's Guide for Plant Appraisal — the recognized professional standard. The approach accounts for species, size, condition, location, and local market factors to produce defensible valuations appropriate for insurance, legal, and real estate contexts.
Local Market Context
Tree valuation requires understanding how trees of different species, sizes, and conditions are valued in the specific local market. In established San Jose neighborhoods like Willow Glen, Almaden Valley, Los Gatos, and Saratoga, large established trees are relatively scarce and highly prized — a context that matters significantly in any valuation.
Do You Need an Appraisal?
You May Need a Tree Appraisal If:
If you're unsure whether a formal appraisal is appropriate for your situation, contact us and describe your circumstances — we'll help you determine the right scope and format before any work begins.
- A tree was damaged or destroyed by a neighbor, contractor, utility company, or third party and you need to establish the value of the loss
- You're filing an insurance claim for storm damage, construction damage, or other tree loss
- You're involved in a legal dispute where tree value is a relevant factor — boundary disputes, easement conflicts, or contractor negligence
- You're buying or selling a property and want to understand how significant trees contribute to overall value
- An HOA, municipality, or court has requested a formal tree valuation
- You want a documented baseline valuation of significant trees for planning or estate purposes
"The difference between a well-supported appraisal and an informal estimate can be significant — particularly where the documented value directly affects the outcome."
Time-Sensitive Situations
For storm damage or recently destroyed trees, having the appraisal done promptly while evidence is still available is important. Contact us as soon as possible so we can assess what documentation exists and what valuation is achievable.
(408) 422-1313Our Process
Our Tree Appraisal Process
Every appraisal reflects a direct on-site evaluation — not a formula applied from a distance.
On-Site Evaluation
Robert visits the property and conducts a thorough assessment of each tree being appraised — examining species, trunk diameter, overall size and form, structural condition, health, and the specific location and context of the tree on the property. For damaged or destroyed trees, the evaluation focuses on establishing the pre-damage condition and value as accurately as the available evidence allows.
Valuation Methodology
Appraisal values are calculated using the ISA's Guide for Plant Appraisal methodology — the recognized professional standard for this purpose. The approach accounts for the species, size, condition, and location of the tree, as well as local market factors that influence how trees of that type and quality are valued in this specific geography.
Findings and Documentation
The completed appraisal report presents the valuation clearly and explains the methodology and factors behind it. The report is prepared to the level of detail required by your situation — whether that's a straightforward single-tree valuation or a comprehensive multi-tree assessment covering an entire property.
Expert Support When Needed
For legal matters or complex insurance negotiations, Robert can provide supporting documentation and professional consultation to help ensure the appraisal findings are properly understood and applied by the relevant parties.
Appraisal Scope
Appraisal Scope We Cover
From a single specimen to several hundred trees across a large estate — every appraisal is scoped to what your situation actually requires.

Common Questions
Frequently Asked Questions — Tree Appraisal
How is tree value actually calculated?
Professional tree appraisals follow the methodology in the ISA's Guide for Plant Appraisal, which is the recognized standard in the industry. The approach evaluates a combination of factors — species, trunk size, overall condition, structural health, and the location and functional contribution of the tree on the property — to arrive at a value that reflects the tree's actual worth. The methodology is designed to produce defensible, consistent valuations that are appropriate for use in insurance, legal, and real estate contexts.
Can a tree appraisal help with an insurance claim after storm damage?
Yes, and it is often essential. Insurance adjusters do not always apply the full value of a significant tree when processing a claim without documented professional appraisal to support it. A formal appraisal prepared by a Board-Certified Master Arborist using recognized methodology gives your insurer a professional basis for the valuation — and gives you a defensible position if the initial settlement offer doesn't reflect the tree's actual value. If you've experienced storm damage, having the appraisal done promptly while the evidence is still available is important.
What if the tree was already removed before I thought to get an appraisal?
A retrospective appraisal is still possible in many situations. Robert can work from photographs, records, and site evidence to reconstruct a reasonable pre-damage or pre-removal valuation. The more documentation that exists — photos, previous assessments, property records — the stronger the appraisal can be. If you're in this situation, contact us as soon as possible so we can assess what evidence is available and what kind of valuation is achievable.
Does tree appraisal affect property value in a real estate transaction?
Significant trees do contribute to property value, and in established neighborhoods throughout San Jose and the surrounding area, mature trees are frequently cited as meaningful factors in buyer interest and comparable sales. A formal appraisal documents that contribution clearly, which can be useful both for sellers wanting to accurately represent their property and for buyers wanting to understand what they're acquiring. It also creates a baseline record that is valuable for the new owner's insurance and estate planning purposes.
How many trees can be appraised in a single assessment?
There is no practical upper limit. We have conducted appraisals covering a single specimen tree and assessments covering several hundred trees across larger properties, estates, and commercial sites. For multi-tree assessments, we'll discuss the scope and format with you before beginning so the report meets the requirements of whoever will be using it.
