What consulting actually involves
A consulting visit buys you a diagnosis rather than a service. The person doing it is looking at the tree with no work to sell you — which is the entire point, and worth confirming before you book, because a "free estimate" from a crew that only earns money by cutting is a different product.
1.Establishing what the assessment is for
The purpose sets the format. General care advice can be a conversation on site. An insurance claim, a neighbour dispute, a permit application or a property purchase needs a written report with photographs, method and conclusions, because a verbal opinion carries no weight in any of those settings. Say which you need when you post the job.
2.Looking at the base first
Most of what kills a mature tree is at ground level. An arborist examines the root collar — often clearing soil or mulch away from it — looking for girdling roots, decay, cavities, fungal fruiting bodies, and evidence of severed roots from old trenching or construction. Soil compaction and a grade that has been raised over the root zone are two of the commonest slow killers, and neither is visible from the crown.
3.Trunk, unions and crown
The trunk is inspected for cracks, cavities, bulges and old wounds; forks are checked for included bark, where two stems have grown together with bark trapped between them rather than fused wood, which is a classic failure point. The crown is read for the pattern of dieback: which branches are dying and in what order says a great deal about the cause.
4.Risk is target, likelihood and consequence
A dead tree in the middle of a field is not high risk. The same tree over a bedroom is. A tree risk assessment asks what would be struck if the tree or part of it failed, how likely that failure is, and how severe the outcome would be — and combines those into a rating. That is also why "is this tree dangerous?" cannot be answered from a photograph: the photograph does not show what is underneath it.
5.Advanced diagnostics, when they earn their cost
Where internal decay is suspected but its extent is unclear, tools such as resistance drilling or sonic tomography can estimate how much sound wood remains. Soil tests and laboratory identification of pathogens are available for the same reason. These are quoted separately and are not needed on most jobs.
6.What the recommendations usually look like
Frequently not removal. Crown cleaning, reducing end weight on an over-extended limb, installing a cable or brace across a weak union, decompacting and mulching the root zone, correcting a raised grade or a misdirected downpipe, or simply re-inspecting on a defined schedule are all common outcomes — as is a clear recommendation to remove, when that is genuinely the answer.
What drives the price of consulting
A consultation is priced on the deliverable and the depth, not on the tree. A verbal opinion on one tree and a written risk report on a whole property are very different pieces of work.
- Verbal opinion or written report
- Writing it up — photographs, methodology, findings, conclusions in a form an insurer, a court or a permitting office will accept — is most of the work, and is where most of the cost sits.
- How many trees
- A single tree is a short visit. Assessing every tree on a property, with an inventory and individual ratings, is a survey.
- Whether diagnostics are needed
- Resistance drilling, tomography, soil analysis and lab work are extra by definition. A good arborist tells you whether the answer will change what you do before recommending them.
- Legal involvement
- Reports intended for litigation, and any expert testimony, depositions or site meetings with other parties, are priced differently from ordinary consulting.
- Turnaround and travel
- A report needed for a deadline this week, or a site a long way from the arborist, costs more than the same work with normal scheduling.
Before you book
- Be specific about what the report is for — insurance, a dispute, a permit, a purchase, or your own decision. It changes the deliverable.
- Gather what already exists: previous reports, prior contractor quotes and recommendations, permit correspondence, and any photographs of the tree over time.
- Know where your property line runs, particularly if a neighbour is involved.
- If it is for a claim or a dispute, do not have any work done on the tree before the assessment. Altering the evidence weakens the report.
- Write down the specific questions you want answered rather than asking for a general look.
- Ask whether the arborist also sells tree work, and decide whether that matters for your purpose.
- Ask for the credential itself — an ISA Certified Arborist qualification is a professional certification rather than a state licence, and contractors on GivingStump can list credentials on their profile for verification.
On the day
- Expect the arborist to spend time at the base of the tree, and to want soil or mulch moved away from the root collar.
- They may want access to a neighbouring viewpoint, or to climb, to see the upper crown properly.
- Walk the site with them and point out the history: construction work, trenching, a changed grade, a new drive, drainage changes, when symptoms started.
- Ask what they are seeing as they go. The reasoning is worth as much as the conclusion.
- Agree what the written deliverable will contain and when it will arrive before they leave.
Is consulting the right call?
Consult before you remove when
The tree matters to you, somebody has recommended removal and you are not sure, or the decision is expensive or irreversible. A consultation costs a fraction of a removal, and the answer is sometimes that the tree can stay.
You need a consultation, not a quote, when
The question is diagnostic — why is it dying, is it safe, what caused this, who is responsible. A crew quoting the work has an answer they are paid to give; a consultant does not.
Skip it when
The tree is unambiguously dead, small, and you simply want it gone. Post the removal.
Book one anyway when
You are buying a property with large mature trees near the house. It is a small cost against the price of the property, and it is the only time you get to find out before the trees are your problem.
Compare with tree trimming, tree planting and tree removal.
Consulting FAQ
What is an ISA-certified arborist?
The International Society of Arboriculture (ISA) is the gold standard for arborist credentialing. Certified arborists have passed a rigorous exam and maintain continuing education. It is a professional certification rather than a state licence — some states and counties also require a separate licence for tree work. Contractors on GivingStump can list their credentials on their profile, and those credentials are reviewed before they are shown as verified.
Do I need a written arborist report?
Written Tree Risk Assessment reports are required for some insurance claims, neighbor disputes, and municipal tree removal permits. Verbal consultations are fine for general care advice or second opinions. If anyone other than you needs to be persuaded, assume you need it in writing.
Can an arborist save a dying tree?
Often yes — disease, pest infestation, soil compaction, and improper care can often be treated before removal is necessary. A consultation assessment is almost always cheaper than removal and replanting. The honest caveat is that some declines are too far along, and a good arborist will tell you that rather than sell you treatment.
Is a hollow tree dangerous?
Not automatically. Trees add wood on the outside, so a hollow trunk with a sound shell can be perfectly stable — many very old trees are hollow. What matters is how much sound wood remains relative to the diameter, whether there are open cavities, cracks or fungal fruiting bodies, how the tree is loaded, and what is underneath it. That combination is what an assessment is for, and it is not something a photograph can answer.
What is the difference between a consulting arborist and a tree service?
A tree service is paid to do work. A consulting arborist is paid to give an opinion, and does not gain from the answer being "remove it". Many companies do both competently, but if the assessment is for a dispute, a claim, or a decision you want independent, ask directly whether the person assessing the tree will be bidding on the resulting work.
Is a second opinion worth it before a removal?
When the tree is significant and the recommendation is removal, usually yes. The cost of finding out sits well below the cost of the removal on this page's guide ranges, and the outcome is either a cheaper course of action or genuine confidence in an expensive one.
My neighbour's tree is a problem — what do I need?
A written assessment describing the tree's condition and the risk it presents, with photographs and a date. What you can then do about it depends on the law where you live, which varies by state and locality — the report tells you what is true about the tree, not what you are entitled to do. Confirm the legal position with your local authority or an attorney, and keep the tree untouched until it has been documented.
Should I get trees assessed before buying a property?
If there are large mature trees near the house, a driveway or a boundary, it is one of the cheapest inspections you can add. Removal of a large failing tree, or remediation of one that has been badly pruned or had its root zone built over, is a real cost that transfers to you at closing along with everything else.
