Arborist Consultation: What Happens, What It Costs

An arborist consultation is a visit from a tree professional who walks your property, inspects your trees, and tells you what is actually going on. It is the first step before any tree work: removal, pruning, cabling, or stump grinding. A good consultation answers three questions: is the tree healthy, is it hazardous, and what should you do about it. Most consultations take 30 to 60 minutes. Many tree companies offer them for free when you are hiring for real work. Formal written assessments for insurance or legal purposes typically cost $150 to $300. I have been doing arborist consultations in Middlesex County, Massachusetts since 1995, and the most common thing I tell homeowners is that their tree is fine. They just did not know what to look for.

\n\n

I am Keith McDonald. I founded McDonald Tree Service in 1995 in Billerica, and I have been walking properties and looking at trees across Middlesex County ever since. Thirty years of consultations has taught me two things: most people call too late, and a few call too early. Both are fixable.

\n\n

When to call an arborist

\n\n

You do not need an arborist every time a branch falls. But you need one when something changes. Here are the situations where a consultation is worth your time:

\n\n

\n
• Dead branches over a structure. If a dead limb is hanging over your house, garage, deck, or driveway, that is a hazard. Dead wood does not get stronger with time. It falls when the wind picks up or the wood decomposes enough that gravity wins.
\n
• Mushrooms or conks at the base. Fungal fruiting bodies on the trunk or around the root flare usually mean internal rot. The tree may look fine from the kitchen window, but the structural integrity is compromised. This is one of the most common things I find on consultations. The homeowner had no idea.
\n
• A new or worsening lean. Trees that have leaned the same direction for twenty years are usually fine. Trees that suddenly lean, especially after a storm, have a root problem and need to come down. The difference is obvious once you know what to look at.
\n
• Bark sloughing off a leader. If bark is falling off in sheets or strips on a main trunk limb, that limb is dying from the inside. It may hold for another season, or it may drop in the next windstorm.
\n
• Woodpecker damage in clusters. A few woodpecker holes are normal. Clusters of holes on the same limb or trunk section mean the bird found a food source, usually insects feeding on already-decaying wood. The woodpecker is not the problem. The rot is.
\n
• Construction or renovation near trees. If you are building an addition, grading the yard, or digging near a mature tree, get an arborist out before the work starts. Root damage from construction is one of the top causes of tree failure in the years that follow, and by the time you notice, the damage is already done.
\n
• You are buying or selling a house. A pre-purchase tree assessment can save you from buying a property with a $5,000 removal problem you did not know about. On the selling side, a clean tree assessment is a trust signal that helps close the deal.

Our guide on when to call an arborist covers the five-point self-inspection you can do from the ground before picking up the phone.

\n\n

What happens during the consultation

\n\n

You call. You describe what you are seeing. We schedule a time. Then here is what happens when I show up:

\n\n

I walk the property with you. You point out what concerned you, and I look at every tree you want assessed. I check the canopy for deadwood, the bark for fungal signs, the trunk for cracks or cavities, the root zone for upheaval or decay, and the overall lean. I look at the species, the age, the proximity to structures, and the site conditions: soil type, drainage, sun exposure.

\n\n

I give you a straight answer on the spot. Not a sales pitch. If the tree is healthy, I tell you. If it needs pruning, I explain what kind and why. If it is a removal, I explain the urgency. Is this a "call us this week" or a "schedule it for winter when the ground is frozen and we do less damage to your lawn" situation. If it does not need anything, I tell you that too.

\n\n

I tell you when NOT to hire us. This is the part that surprises people. If the tree is fine, I say so. If a homeowner with a pruning saw and some common sense can handle the deadwood, I say that. We have been in business since 1995 because we do not sell work that does not need doing. Some of our best jobs are the ones we talked someone out of.

\n\n

I leave you with a plan. Whether that is "do nothing, the tree is healthy," or "we should prune these three limbs before winter," or "this tree needs to come down and here is why." If you want a written estimate for the work, I provide one. No pressure. No "sign today for 10 percent off." You take the information and decide on your own time.

\n\n

For a deeper look at how we evaluate tree hazards, our tree risk assessment guide covers the industry standards we follow.

\n\n

What you get after the visit

\n\n

For a standard consultation, the kind where I walk the property and give you my honest opinion, you get verbal recommendations on the spot and a written estimate if work is needed. That is it. No binder. No report with charts.

\n\n

For situations that need documentation: insurance claims, legal disputes, real estate transactions, municipal requirements, you want a formal tree risk assessment. That comes with a written report, risk ratings per tree, photos, and recommendations. It follows industry standards and holds up if it ends up in front of an adjuster or a lawyer.

\n\n

Most residential homeowners need the first kind. The formal assessment is for specific situations where someone else needs to see the paperwork.

\n\n

What it costs

\n\n

Here is where the industry makes things confusing. Some companies charge for consultations. Some do not. Some charge for the visit but credit it toward the work if you hire them. There is no standard.

\n\n

We do not charge for consultations when you are hiring us for tree work. You call, I come out, I tell you what is going on, and if we do the job, the visit was part of the job. If you decide not to hire us, the visit was still free. That is how we have done it since 1995.

\n\n

Formal written assessments, the insurance-claim, legal-documentation kind have a fee because they take significantly more time and produce a formal report. The range in Middlesex County is typically $150 to $300 depending on how many trees and how complex the situation is.

\n\n

Always ask before the visit whether there is a charge. Any reputable company will tell you upfront. If they will not answer that question, that is your first red flag.

\n\n

When you do NOT need an arborist

\n\n

I say this a lot, and it is worth repeating: not every tree concern requires a professional visit. Here is when you can skip the call:

\n\n

\n
• A few dead branches in an otherwise healthy canopy. Every mature tree has some deadwood. If the tree looks full and healthy and the dead branches are small (under wrist-thick), that is normal seasonal dieback. Prune them out yourself with a hand saw if they bother you.
\n
• The tree is dropping leaves or seeds. That is what trees do. A maple dropping helicopters in May is not sick. An oak dropping acorns in October is not dying. If the canopy is full and green during the growing season, the tree is fine.
\n
• You want the tree gone for a view or a pool. That is a removal decision, not an arborist consultation. Call us for a removal quote. We will come out, size up the job, and give you a number. No assessment needed.
\n
• Small branches after a storm. If the storm dropped a few small limbs and the canopy looks intact, the tree probably survived fine. Clean up the debris. If you see large broken limbs still attached or a split in the trunk, then call.
\n

\n\n

The rule of thumb: if you can describe the problem specifically: "there is a mushroom the size of a dinner plate at the base of the oak," call an arborist. If your concern is "the tree looks weird" but you cannot name what is wrong, take a photo this month and compare it to a photo next month. If nothing changed, the tree is probably fine.

\n\n

How to choose the right arborist

\n\n

Not every tree company employs certified arborists, and not every certified arborist runs an honest business. Here is what to look for:

\n\n

\n
• ISA certification. The International Society of Arboriculture certifies arborists who pass an exam and maintain continuing education. It is not a guarantee of quality, but it is a baseline. Ask if the person visiting your property is ISA-certified, not just whether the company has one on staff somewhere.
\n
• Proof of insurance. Tree work is one of the most dangerous trades in the country. If the crew does not have liability insurance and workers' compensation, a bad day on your property becomes your problem. Ask for a certificate of insurance before any work starts. Any legitimate company will provide one without hesitation.
\n
• Local track record. A company that has been operating in the same county for years has a reputation to protect. We have been in Middlesex County since 1995. The national chain that opened a branch last spring does not have the same stake in getting it right.
\n
• They tell you when NOT to hire them. This is the single biggest signal. If every tree needs work and every job is urgent, you are talking to a salesperson, not an arborist. The good ones will tell you when your tree is fine.
\n

\n\n

What to do before the arborist arrives

\n\n

A little preparation makes the consultation more useful:

\n\n

\n
• Walk the property yourself first. Note which trees concern you and why. Take photos of anything that looks off: cracks, mushrooms, leaning, dead branches. The arborist will look at everything, but your observations help focus the visit.
\n
• Know your property lines. If the tree is near a boundary, know whose tree it is. In Massachusetts, MGL Chapter 87 governs tree disputes between neighbors. If the tree is on town property, even if it has been shading your yard for fifty years, it is not your tree to remove.
\n
• Write down your questions. If you want to know whether the tree is safe, whether it needs pruning, whether it can survive another five years, write it down. Consultations go fast, and you will forget half your questions if they are not on paper.
\n
• Check your town's tree bylaws. Several of our service towns, including Chelmsford and Lexington, have specific regulations about tree removal permits, especially for street trees or trees over a certain diameter. Knowing this before the visit helps us plan accordingly.

Common misconceptions about arborist consultations

\n\n

"An arborist will just tell me to remove the tree." Not a good one. The whole point of a consultation is to figure out what the tree actually needs. Sometimes that is removal. More often it is pruning, cabling, or nothing at all. If every consultation ends with a removal quote, get a second opinion.

\n\n

"I can tell if a tree is healthy by looking at the leaves." Leaves tell you about the current growing season. They do not tell you about internal decay, root damage, or structural weaknesses. A tree can have a full green canopy and a trunk that is 40 percent hollow. The leaves are the last thing to show problems and the first thing to recover. A stressed tree can push out a full canopy right up until the year it fails.

\n\n

"Consultations are just a sales tactic." Some are. The national chains send a salesperson who gets a commission on removals. That is not a consultation. It is a sales call. A real arborist consultation ends with honest information, not a contract. We have talked more people out of tree removal than into it.

\n\n

"I should wait until the tree falls to deal with it." The most expensive tree removal is the one that goes through your roof first. A $300 pruning job today prevents a $15,000 insurance claim next storm season. The consultation is the cheapest part of the whole process.

\n\n

Straight answers

\n\n

How much does an arborist consultation cost? Many tree companies offer free consultations when you are hiring for actual work. Formal written assessments for insurance or legal purposes typically run $150 to $300. Always ask upfront.

\n\n

How long does it take? 30 to 60 minutes for most residential properties. Longer if you have a lot of trees or a complicated situation.

\n\n

Do I need a certified arborist or will any tree person do? For a consultation, you want someone who can identify diseases, assess structural integrity, and give you an honest recommendation, not just someone with a chainsaw. ISA certification is the baseline.

\n\n

What if the arborist says the tree is fine but I am still worried? Get a second opinion. Any honest arborist will not be offended. If two out of three say the tree is fine, it is probably fine.

\n\n

Can I just send a photo instead of having someone come out? Photos help for an initial conversation, but they do not replace a walk-through. I cannot see root upheaval, internal decay, or bark texture from a phone picture. The visit matters.

\n\n

The bottom line

\n\n

An arborist consultation is the cheapest part of any tree decision. It costs you nothing when the company does honest work, and it can save you thousands by catching problems early or talking you out of work you did not need. Thirty years of doing this in Middlesex County has taught me that the best tree work is often the tree work you do not do.
