How to Choose a Tree Service Company

Hiring the wrong tree service company can cost you thousands of dollars in property damage, leave you liable for injuries on your property, or result in shoddy work that creates new hazards. I am Keith McDonald, owner of McDonald Tree Service in Billerica, MA. We have been doing tree work across Middlesex County since 1995, and in that time I have seen homeowners get burned by unlicensed operators, storm chasers, and companies that disappear after cashing the check.

Here is how to find a tree service company you can trust, what to ask before you sign anything, and the red flags that should send you running.

Verify Insurance Before Anything Else

This is the single most important step. A tree service company must carry two types of insurance:

• General liability insurance: Covers damage to your property. If a crew drops a limb on your roof, their insurance pays for the repair — not yours. Minimum coverage should be $1 million per occurrence.
• Workers' compensation insurance: Covers injuries to the crew. Tree work is one of the most dangerous occupations in the country. If an uninsured worker falls out of your tree and breaks his back, you can be held liable as the property owner.

How to verify: Ask for a Certificate of Insurance (COI). Any legitimate company will provide one within 24 hours. Call the insurance company listed on the certificate to confirm the policy is active. Certificates can be forged or expired. A 5-minute phone call protects you from a six-figure liability.

We carry full general liability and workers' compensation coverage on every job, whether it is a small pruning in Wilmington or a crane removal in Lexington. We provide certificates to every customer who asks, and we encourage you to verify.

Check for Proper Licensing

Massachusetts does not require a state-level license to perform tree work, which is part of the problem. Anyone with a pickup truck and a chainsaw can call themselves a tree service. That does not mean they know what they are doing.

What to look for instead:

• ISA Certified Arborist: The International Society of Arboriculture (ISA) certifies arborists who pass a comprehensive exam and maintain continuing education. An ISA certification means the person has demonstrated knowledge of tree biology, pruning standards, risk assessment, and safety.
• Massachusetts Pesticide Applicator License: Required for any company that applies pesticides or treatments. If a company offers plant health care, disease treatment, or pest control, they need this license.
• OSHA compliance: Tree companies should follow OSHA standards for chainsaw operation, aerial lifts, rigging, and personal protective equipment. Ask if their crew is OSHA-trained.

Questions to Ask Before Hiring

When you call a tree company for an estimate, ask these questions:

1. Will you provide a written estimate?

A verbal quote is worth nothing. Get every detail in writing: scope of work, price, what is included (cleanup, stump grinding, debris removal), and timeline. If the company will not put it in writing, move on.

2. Who will be on-site during the job?

You want to know that a qualified person — ideally the one who gave the estimate — will oversee the work. Some companies send the owner for the estimate and then dispatch an inexperienced crew. At McDonald Tree Service, I give every estimate personally and oversee the work across Chelmsford, Tewksbury, Bedford, and every other town we serve.

3. How will you remove the tree?

A good company will explain the plan: climbing vs. bucket truck vs. crane removal, where pieces will be dropped, how the canopy will be rigged, and what equipment will be on your property. If they cannot explain the plan clearly, they do not have one.

4. What happens if something goes wrong?

Damage happens occasionally even with the best crews. A professional company will tell you their process: they document existing conditions, they carry insurance that covers damage, and they take responsibility when mistakes happen. A company that says "nothing ever goes wrong" is either lying or inexperienced.

5. Do I need a permit?

A knowledgeable local company will know the permit requirements in your town. In Lexington, you need a permit for any tree over 12 inches in diameter. In Carlisle, conservation restrictions apply to many properties. In Bedford, the Tree Preservation bylaw triggers review for trees over 10 inches. If a company does not know the local rules, they are not truly local.

Red Flags That Should Disqualify a Company

Door-to-door solicitation

Legitimate tree companies do not drive around neighborhoods knocking on doors, especially after storms. Storm chasers roll into towns like Dracut, Lowell, and Andover after every nor'easter, offering cut-rate prices to homeowners with fresh damage. They do substandard work, take the cash, and disappear. If someone knocks on your door unsolicited, say no.

No insurance documentation

If a company cannot or will not produce a Certificate of Insurance, they are either uninsured or underinsured. Either way, you are exposed. Do not accept verbal assurances. No certificate, no hire.

Significantly lower price than competitors

If three companies quote $1,500 and one quotes $600, the $600 company is cutting corners. They are skipping insurance, using untrained labor, or planning to leave the stump, roots, and half the brush in your yard. Cheap tree work is expensive tree work when you factor in the risks.

Demand for full payment upfront

A reasonable deposit (25-50%) is normal for large jobs. Full payment before work begins is a red flag. You lose all leverage if the company does a poor job or does not finish.

Topping trees

If a company suggests "topping" your tree — cutting the main leaders back to stubs — find a different company. Topping is the worst thing you can do to a tree. It destroys the tree's structure, promotes weak regrowth, increases the risk of failure, and violates every arboricultural standard. Any company that tops trees does not understand tree biology. Read our pruning vs. removal guide for proper pruning methods.

No physical address or local presence

A company should have a verifiable local address, not just a phone number. Check Google reviews, the Better Business Bureau, and ask how long they have been working in your area. We have been based in Billerica since 1995 and have served homeowners across Woburn, Burlington, Westford, and 15 other towns for three decades.

How to Compare Estimates

Get at least three written estimates. When comparing them, look at:

• Scope of work: Is each estimate for the same work? One company might include stump grinding while another lists it as extra.
• Cleanup: Does the estimate include full cleanup, brush chipping, log removal, and raking? Or will you be left with a pile of debris?
• Timeline: When will the work happen? A company that can start tomorrow during peak season may not have enough work to stay busy, which is its own red flag.
• Payment terms: Reasonable deposit, balance on completion. Avoid companies that want full payment upfront or cash only.

Why Local Matters

A company based in your area knows the local tree species, soil conditions, weather patterns, and municipal regulations. They have a reputation to protect. They are not disappearing after your job — they will drive past your property next week on their way to another job in the same town.

We live and work in the communities we serve. When we remove a tree in Concord or prune oaks in Acton, our name is on that work permanently. That accountability is something a fly-by-night operation will never offer.
