How to Choose a Tree Service in Michigan: Insurance, Oak Wilt Timing, and Bids You Can Compare

Michigan does not issue a statewide tree service license. Anyone with a chainsaw, a chipper, and a magnetic sign can print business cards and start knocking on doors, and after a bad storm plenty of them do. That absence of a credential puts the entire burden of vetting on the homeowner.

Tree work is also the highest risk trade that regularly shows up in a residential yard. A climber sixty feet up over a roofline with a running saw is doing something that goes wrong badly when it goes wrong, and the financial consequences land on whoever is uninsured. Price should be the last thing you compare, not the first.

The state gives you two more filters that most homeowners never use. Michigan has a specific window when oak trees should not be cut, and it has millions of standing dead ash trees that change how a removal has to be performed. How a company answers questions about either one tells you almost everything.

The Insurance Certificate Comes Before the Estimate

Ask for two certificates before a bid, not after. General liability covers damage to your house, your fence, and your neighbor's garage, and workers compensation covers the crew. A company carrying only the first is one injury away from a claim that finds its way to your homeowners policy.

Have the certificate emailed from the insurance agency directly to you. Certificates forwarded as PDFs by the salesperson get edited, expire, or belong to a policy that lapsed in March. This takes one phone call and it is the single most useful thing you can do.

Coverage amounts matter as much as existence. A million dollars in general liability is a reasonable floor for residential removals, and crews working near structures or power lines should carry more. Compare the number on the certificate against what your roof would cost to replace.

Some outfits claim an exemption from workers compensation because everyone on the truck is a subcontractor. Treat that answer as a decline. In practice it means the crew has no coverage, and the arrangement exists to shift risk off the company and onto you.

Certifications Michigan Does Not Require but Good Companies Carry

Because there is no state license, the meaningful credentials in this trade are voluntary. The International Society of Arboriculture certifies arborists through an exam and continuing education, and the Tree Care Industry Association accredits companies on safety practices and business standards. Neither is required by law in Michigan, which is exactly why carrying one signals something.

A certified arborist diagnoses, and a tree worker removes. Those are different skills, and the distinction matters most when you are trying to decide whether a tree can be saved. A company whose only recommendation is always removal may not have anyone qualified to offer the alternative.

Pesticide and fungicide work brings a real state requirement into the picture. Anyone applying treatments for hire, including oak wilt fungicide injections or emerald ash borer preventive treatments, needs certification through the Michigan Department of Agriculture and Rural Development. Ask for that credential specifically if treatment is part of the proposal.

Who Is Climbing and What They Are Trained To Do

Ask who runs the job on the day. Some companies sell with an arborist and staff with a rotating day crew, which is common and not automatically a problem, though it changes what you should expect. A crew leader with a decade of climbing experience is worth more than a certificate framed in an office.

Line clearance work is its own qualification. Any branch within ten feet of a primary conductor belongs to a line clearance qualified crew or to the utility, and a general tree service should decline it. A company that offers to trim around a service drop for cash is telling you what its safety culture looks like.

Ask About Oak Wilt Timing and Listen Closely to the Answer

Oak wilt is a fungal disease that has moved through Michigan oaks for decades, and it spreads two ways: underground through connected root systems and above ground by sap beetles drawn to fresh wounds. The beetle path is the one you control. Cutting an oak during the warm months hands the disease an open door.

Michigan guidance has long been to avoid pruning or wounding oaks between roughly April 15 and July 15, and many arborists extend that window to be safe. Winter pruning is the standard recommendation, when the beetles are inactive and the tree is dormant. Emergency storm damage is the exception, and the wound should be sealed immediately in that case.

Use this as a screening question rather than a trivia quiz. Call in June, describe an oak that needs shaping, and see what the company says. A crew that offers to come out Tuesday without mentioning the risk has either never heard of oak wilt or does not care, and either answer disqualifies them.

Red oaks die fast once infected, sometimes within a single season, while white oaks decline more slowly. Neighborhoods with mature red oaks in Ann Arbor, Grand Rapids, and much of the northern Lower Peninsula have lost whole clusters this way. A company that understands root graft severing and trenching is one worth keeping in your contacts.

Dead Ash Trees Change How the Work Gets Done

Emerald ash borer has killed ash trees across every county in the Lower Peninsula, and a large number of them are still standing in yards, fencerows, and woodlots. A dead ash is not a normal removal. The wood dries brittle and unpredictable, limbs shed without warning, and the tree can fail while a climber is tied into it.

Reputable companies will not climb a long dead ash. They bring a bucket truck, and on larger or tighter properties they bring a crane, which is why quotes on dead ash run twenty to fifty percent above a comparable live tree. A company that quotes a dead ash at the same price as a healthy maple either has not looked at it or plans to climb it.

Access drives the equipment decision, and equipment drives the price. A dead ash in an open side yard reachable by a bucket truck might run $900 to $2,000, while the same tree wedged between a garage and a property line requiring crane time can reach $2,500 to $5,000. Ask which machine they intend to use and where it will sit.

Timing has stopped being optional on these. Every additional winter of freeze and thaw makes the tree more dangerous and more expensive to take down, and insurers increasingly ask about standing dead trees near structures. The cheapest version of this job was several years ago.

After a Storm, Watch for the Trucks That Appear Overnight

Ice storms produce the worst of it. The ice event that hit the northern Lower Peninsula in the spring of 2025 flattened crowns across whole counties and drew crews from several states, and the honest ones were mixed in with people who took deposits and disappeared. That pattern repeats after every major event.

Storm work does justify emergency pricing. A tree on a roof at midnight, a crew called in on overtime, and a crane mobilized on short notice all cost real money, and $1,500 to $5,000 for an emergency removal is not a gouge by itself. What separates fair from predatory is documentation.

Protect yourself with three habits. Do not pay in full up front, get the scope in writing even when the yard is a mess, and photograph everything before the saws start for the insurance claim. Homeowners policies generally cover removal when a tree hits a covered structure and generally do not when it simply falls in the yard.

Verify a local address and a Michigan phone number. Out of state plates and a cell number with an unfamiliar area code are not proof of anything by themselves, though combined with a demand for cash they should end the conversation. A company you can find again in November is worth paying a little more for in April.

Getting Bids You Can Line Up Side by Side

Written scope is what makes three quotes comparable. The document should name each tree, state whether it is being removed or pruned, and specify what happens to the wood, the brush, and the stump. Verbal agreements on tree work fall apart at exactly the moment the yard is full of debris.

Stump grinding is the most common surprise. It is usually priced separately at roughly $3 to $6 per inch of diameter with a minimum around $100 to $150, and the bid should state the grinding depth and whether the grindings get hauled away or left in a pile. Six inches deep and backfilled is a different product than a surface pass.

Wood ownership deserves a line of its own. Some companies leave rounds stacked at no charge, some haul everything, and some charge for disposal, and each is defensible as long as you knew going in. If you want firewood length pieces, say so before the crew starts bucking.

Property protection is the last item worth negotiating. Ask how they will protect the lawn from a bucket truck's outriggers, what happens if the driveway cracks, and who repairs an irrigation line cut by the stump grinder. Sending the identical written scope to three tree service companies serving your area is the only way to compare, and our home service cost guides for Michigan homeowners walk through the same approach for other trades.

Frequently Asked Questions

Do tree services need a license in Michigan?

There is no statewide tree service or arborist license, so insurance and voluntary certification are the credentials that carry weight. Applying fungicides or insecticides for hire is different and does require certification through the Michigan Department of Agriculture and Rural Development.

When should I not prune oak trees in Michigan?

Avoid pruning or wounding oaks from roughly mid April through mid July, when sap beetles carrying oak wilt are active and drawn to fresh cuts. Winter is the safe window, and storm damage during the risky months should be sealed the same day it happens.

Why do dead ash trees cost more to remove?

Brittle wood makes climbing unsafe, so crews bring a bucket truck or a crane instead of a climber, and that equipment adds twenty to fifty percent to the price. Waiting another year or two typically raises the cost again as the tree deteriorates further.

How much should I pay upfront for tree work?

A deposit of ten to twenty five percent on a large scheduled job is reasonable, and full payment before any work happens is not. After a storm, a legitimate company will still put the scope in writing before asking for money.

Does homeowners insurance cover tree removal in Michigan?

Coverage generally applies when a tree falls on a covered structure such as a house, garage, or fence, subject to your deductible and often a per tree cap. A healthy tree that simply falls in the open yard is usually the homeowner's expense, which is why proactive removal of dead ash rarely gets reimbursed.
