How to choose a tree care company in Columbus

The licensing picture, stated plainly

The Ohio Construction Industry Licensing Board issues licenses to qualified electrical, heating ventilating and air conditioning, plumbing, hydronics and refrigeration contractors, and regulates commercial contractors who perform those five specialty trades. Tree work is not among them, so a company cannot hold an Ohio tree care contractor license, and a claim that it does should be read carefully.

Columbus does not fill the gap either. The City's license and registration chapter, Title 41 Chapter 4114, covers department-issued contractor licenses, home improvement general and limited contractors, registration of OCILB-licensed specialty contractors, general contractors, demolition contractors, and fire alarm and fire protection companies. The home improvement limited license specializations are listed exhaustively, from residential roofing through irrigation sprinkler to gypsum board, and tree work appears nowhere in the list.

What follows from that is not that tree work is unregulated. It is that the regulation attaches to particular activities, notably pesticide application, and to the tree itself when it is a public tree, rather than to the trade as a whole.

Pesticide work is the one clear license

The Ohio Department of Agriculture is direct about it: you need a pesticide business license if you are hired to apply any pesticide to someone else's property in Ohio, or solicit to make pesticide applications in Ohio, or conduct diagnostic inspections for wood destroying insects for a real estate transaction. At least one Ohio-licensed commercial applicator must be employed for each licensed business location the company owns or operates.

Two details make this checkable. Business licenses are valid for one year and expire on September 30, so ask for the current one rather than a scanned certificate of unknown vintage. And a current certificate of insurance or binder with appropriate coverage must be on file with ODA's office as a condition of that license, which gives you a second reason to ask for the insurance paperwork.

Ask the company for its ODA pesticide business license, and ask for the name of the commercial applicator who will actually do the work. ODA publishes a searchable list of licensed commercial and private pesticide applicators in Ohio with a downloadable CSV, so a named individual can be checked. The category codes that matter for tree work are 6a, general ornamental pest control, and 6c, ornamental weed control. The applicator list is a list of people, not of businesses, so it answers the question about the individual and not the question about the company.

What an ISA credential means, and what this directory has not done

ISA Certified Arborist is a credential issued by the International Society of Arboriculture, a private body, to an individual who passes its exam and keeps it current through continuing education. The City of Columbus adopts that credential as its standard for work on public trees, which is why it carries weight locally, but adopting a credential is not the same as issuing a license. A company does not hold the credential; a person on its staff does.

OSU Extension's guidance on hiring an arborist tells homeowners to visit the ISA website and use Find an Arborist, where you can search by zip code or city and see the credentials earned by arborists in your area. ISA's public directory at https://www.treesaregood.org/Find-an-Arborist is built for exactly that: it describes itself as a platform to help the public find and verify ISA-credentialed tree care professionals, with credential verification and profiles managed by the credential holders.

Say a listing on this site mentions ISA certification or TCIA membership. That line came from the business's own material. No company's credentials have been verified against ISA or TCIA for this directory, and the listing does not assert that they were. If the credential matters to your decision, get the individual's name and check it yourself.

Insurance, quotes and the paperwork to ask for

OSU Extension's advice is worth following literally: companies should be bonded and insured, you should request certificates of insurance including proof of liability for personal and property damage and worker's compensation, and you should phone the insurance company to verify current policy information rather than accepting a document at face value.

The same guidance says to obtain several quotes before buying tree services, not to always accept the lowest bid, never to pay in advance, and to be wary of door-knocking salespeople, who are especially common after storms. It also suggests asking for local references for jobs the company has done and speaking to those clients.

Ask what the quote includes rather than only what it totals: whether debris is hauled away or left, whether stump grinding is a separate line, whether the wood stays with you, and who is responsible for lawn and hardscape protection.

Who pulls the permit

If the tree is in a Columbus street, park or other public space, the tree care company's certified arborist submits the Forestry permit application and there is no fee to apply. A company that does not know this, or that offers to work on a street tree without mentioning it, has told you something useful.

Get the permit question settled in writing before scheduling. It is also the fastest way to find out whether the company has a certified arborist available at all, since the City requires the work to be approved for execution by one.

How payment works on this site

Paid placement never changes organic ranking here. Ordering and inclusion in the listings, the category pages and the search results are decided the same way whether or not a business has paid for anything.

Featured and sponsored placements are labeled wherever they appear, so a paid position is identifiable as one. Payment never affects a listing's verification status either: the verification label describes what was checked and against what, and no amount of money moves it.
