How do I know a tree company is legit?
A legitimate tree company can show a current certificate of insurance (general liability, commonly $1,000,000 per occurrence, plus workers' compensation), a physical address and a working phone number, a written itemized quote, and references you can call. Most states do not license tree work specifically, so insurance is the real test. Checking all of it takes about 10 minutes.
Anyone with a pickup and a chainsaw can call themselves a tree service. In most of the country there is no license to check, so "are they licensed?" does not get you far. What separates a real company from a risky one is insurance, a fixed location, paperwork, and a track record. All four are easy to check without taking anyone's word for it.
| Check | What to ask for | How to confirm it | Time |
|---|---|---|---|
| Insurance | Certificate of insurance (COI) for general liability and workers' compensation | Have the insurance agent send it to you directly; check dates and coverage | 2 minutes to ask, a day to receive |
| License | State contractor or tree-expert license number, where your state has one | State licensing board website | 2 minutes |
| Credentials | ISA Certified Arborist name and number | ISA public directory | 2 minutes |
| Physical presence | Street address, local phone, name on the trucks | Map search, call the number, check the name on the truck matches the quote | 2 minutes |
| Track record | Two references from similar recent jobs; online reviews | Call the references; read the one-star reviews for patterns | 5 minutes |
Do tree companies need a license?
In most states, no. Tree removal and pruning are not licensed trades the way plumbing and electrical work are. A handful of states and some cities do require something: a general contractor's license once the job value passes a threshold, a specific tree-expert or arborist license in a few states, or a pesticide applicator license for anyone spraying or injecting trees. Your state contractor board's website will tell you in a minute whether any of that applies. Where it does, look the number up and confirm it is active. Where it does not, do not mistake a city business license for a qualification; it means they paid a fee, nothing more. The vetting then rests on insurance and credentials.
How do I verify a tree company's insurance?
Ask for a certificate of insurance and ask that the company's insurance agent send it to you directly by email. That one step defeats the most common trick, which is a photocopied certificate from a policy that lapsed last year. On the certificate, look for two lines: general liability, commonly $1,000,000 per occurrence, which covers damage to your house, fence, or car; and workers' compensation, which covers the crew if someone is hurt. Check that both policy periods include the date of your job. Honest companies hand this over without blinking, because they are asked every week. What each coverage does, and what happens to you if it is missing, is on why must a tree service be insured?
Does a tree company need an ISA Certified Arborist?
Not to be legitimate, but it changes what you can expect. ISA Certified Arborist is a credential earned by a person, not a company, after passing an exam and documenting experience, and it has to be renewed with continuing education. It tells you someone on staff knows how trees respond to cuts, which matters most for pruning. A company with a certified arborist is much less likely to offer topping or to climb a live tree with spikes. You can check any name in the ISA's public directory in two minutes; how to verify an ISA Certified Arborist walks through it.

What should a legitimate tree company's quote look like?
Written, dated, and itemized. It should carry the company's legal name, address, and phone, describe each tree by location or species, and price or mark as included each part of the work: felling or dismantling, chipping, haul-away, stump grinding, cleanup, and any permit or crane. It should state the total, the deposit if any, and when payment is due, and it should say what happens to the wood. A number on a business card after a drive-by is not a quote, and neither is a phone estimate. What tree removal includes covers the items that are most often left out.
Is it a bad sign if a tree company has no website?
By itself, no. Many good small crews are booked solid through word of mouth. What you need is a way to find the company after the job if a fence is broken or a stump was skipped: a street address, a phone that is answered, a name on the truck that matches the quote. No website plus no address plus no insurance certificate is a different story, covered on the red flags of a bad tree service. For online reviews, read the one-star ones for patterns: no-shows, surprise charges, damage disputes.
How do you vet a tree company in about 10 minutes?
- Search the name and address. Confirm the address is real, not a mail drop, and the phone number connects to the company.
- Ask for a certificate of insurance. Have the agent email it directly. Confirm general liability, commonly $1,000,000 per occurrence, and workers' compensation, both current.
- Check the license where one exists. If your state licenses tree work or contractors above a job value, confirm the number is active on the state board site.
- Look up credentials. If the company claims an ISA Certified Arborist, check the name in the ISA directory.
- Call two references. Ask whether the crew showed up on time, cleaned up, and charged the quoted price.
If a company passes all five, what remains is price and scope; the questions to ask before hiring picks up there.
