How to Check a Tree Company's Certified Arborist and Insurance in Ohio

Most of what a tree company tells you about itself cannot be checked. A small part of it can, and in Ohio that part is specific: a credential that belongs to a named person, a workers’ compensation record the state itself publishes, and one license that only matters if somebody wants to put a needle in your ash tree. Those are worth working through in the order a hire actually happens, starting with the words on the truck.

Does a tree service have to be licensed in Ohio?

No. Ohio issues no state trade license for tree work. No state agency examines a tree company or has the power to pull its right to climb. So “licensed and insured” on a magnet sign is carrying only the second word, which is fine, because the second word is the one you can verify.

There is a smaller thing the word sometimes points at. A municipality can require a contractor registration or a vendor’s license to do business inside its limits, and a company may hold one. That is a filing and a fee. It proves the business is registered to work inside those limits and says nothing about whether anyone on the truck knows where a cut belongs.

How do you check that an arborist is really ISA certified?

The credential belongs to a person, not to a company. An ISA Certified Arborist has passed an examination from the International Society of Arboriculture, carries a certification number, and keeps the credential current with continuing education. So the useful question is a name. Get it, then look it up yourself in the ISA’s public credential search at isa-arbor.com, which runs on a person’s name or certification number, not a company’s.

Then ask the question that decides whether the credential touches your tree at all:

• Does that person walk the property before the estimate is written?
• Are they on site the day of the work, or reachable by the crew leader?
• Whose call is it when the plan changes once someone is up in the tree?

An outfit that answers those plainly is putting the credential on your job. One that gives you a name and never mentions it again is keeping it on the website. Where the difference shows up is the cut itself, which is why the page on tree trimming in Elyria spends its space on unions and percentages instead of price.

What insurance should an Ohio tree company carry, and how do you see the proof?

Two policies, checked two different ways. General liability covers damage to your house, your fence, your neighbor’s garage. Workers’ compensation covers the people doing the climbing. Ask for the liability certificate to come from the insurance agency rather than as a photo on somebody’s phone, and ask about comp separately, because in Ohio comp does not come from the same place.

A certificate of liability insurance is a one-page form the agency issues, and you can be named on it as the certificate holder for your job. What matters there is the routing. When the request goes to the agency, the document that comes back is current by definition. The photo in a phone gallery is current only until the policy it describes lapses, and lapsed coverage is the common failure, not fake coverage. Read the expiration date first. If it falls before your work is scheduled, the conversation is over until a new one arrives.

Why does workers’ comp matter more in tree work than in other trades?

Because this is the trade where somebody is forty feet up on a rope with a running saw over your roof. Ohio is a state-fund state. Private employers buy workers’ compensation from the Ohio Bureau of Workers’ Compensation rather than from a private carrier. That makes Ohio comp easier to check than comp anywhere with a hundred carriers, because the BWC publishes an employer coverage lookup that anyone can use.

So the ask is different from the liability ask. You want the legal name the business is registered under, which is often not the name on the truck, and then you look it up yourself. There is one honest wrinkle. A genuine one-man operation is not required to cover himself and may carry no comp policy at all, which is legitimate right up to the afternoon he brings a helper. If the estimate says one climber and three people show up, the answer you got last week no longer describes the crew in your yard.

Who has to be licensed to treat an ash tree for emerald ash borer?

This one does require a license. Applying pesticide to someone else’s property for hire takes a commercial pesticide applicator license from the Ohio Department of Agriculture, and a trunk injection for emerald ash borer is a pesticide application. The climber who offers to save your ash needs a credential that the tree work itself does not require. Ask who holds it.

Whether treatment is even the right call is a separate question, and it turns almost entirely on how much canopy the tree has already lost. The guide on when a thinning ash is still worth treating works through that timing for Elyria, where the borer wave came through years ago.

A crew knocked on the door after the storm. What do you ask before they start?

The same two insurance proofs, plus a written scope before anything is cut and a local number that will answer tomorrow. Storm work is legitimate, it is genuinely more dangerous, and it carries a real premium. Our own range for an emergency or storm call is the scheduled rate plus typically 25-50%, and what storm work costs explains what that premium is paying for.

The number to walk away from is the one that triples because the whole county is calling at once. Trucks nobody in the neighborhood has seen before work these streets for a week after a big wind, and some of them are fine. Watch the pressure rather than the plates: a price that only holds if you say yes on the porch, cash asked for before work starts, a scope that stays verbal because a verbal scope can grow. A deposit on a large scheduled job is ordinary. Money handed over on a doorstep for work that begins “as soon as we finish down the street” is not.

What should a written estimate actually say?

Enough that a second company could bid the same job from it without asking you a question. The tree identified by location and rough size, the work described in terms of what comes off, who is doing the cutting, where the wood and the brush end up, the stump as its own line with its own number, and when payment is due. A free written estimate before any work is normal around here, and it is what we would want you to ask of any tree service in Elyria, including us.

The estimate is also where the first two sections stop being abstract. The certified person’s name can sit on the document. So can the insurance agency’s name and the policy expiration. Nobody has to add any of that unprompted, and most estimates will not have it. Ask once, in writing, and you have a paper record of who said what before a saw started, which is worth more than the same answers given in a driveway.

What happens if an uninsured crew gets hurt in your yard?

The exposure comes looking for the nearest available policy, and yours is standing right there. A climber who falls on a job with no workers’ compensation behind him has a medical bill and lost income and no employer coverage to absorb either, and the search for a payer typically arrives at the homeowner’s liability coverage. Your carrier may end up defending the claim, or paying it, and then trying to recover from a company whose assets are a chipper and a pickup.

That is why the certificate request is worth making even when the crew seems fine. The question is who absorbs the cost if a climber gets hurt on your property, and it gets answered before anyone leaves the ground. Make both checks in the days between accepting the estimate and the truck showing up: one email to the insurance agency for a current certificate, and one search of the BWC coverage lookup under the legal business name.
