Not everyone with a chainsaw and a truck is a tree professional. Some are skilled arborists. Some are handymen picking up side work. Some are outright scammers who take deposits and vanish.

I’ve spent years cleaning up after bad tree work. Topped trees that will never recover. Stumps cut two feet high because the saw was too small. Damage to roofs, fences, and cars that the previous crew walked away from. The homeowners thought they were saving money. They ended up paying twice.

Here’s what to watch for before you hire anyone.

No Insurance or Won't Prove It

This is the biggest red flag. A legitimate tree company carries general liability insurance and workers’ compensation. Liability covers damage to your property. Workers’ comp covers injuries to the crew.

Ask for a certificate of insurance. Any real company will email it within minutes. The certificate should list current dates and adequate coverage amounts. For tree work, look for at least $1 million in general liability.

Don’t just look at the paper. Call the insurance company and verify the policy is active. Some contractors show expired certificates or policies they’ve canceled. A five-minute phone call protects you from a liability nightmare.

If a company hesitates, makes excuses, or refuses to provide proof, walk away. No exceptions.

Door Knockers After Storms

A big storm rolls through. Trees are down everywhere. The next morning, a truck pulls into your driveway and a guy offers to clear your fallen oak for cash, today only, special storm pricing.

These are storm chasers. They follow severe weather from town to town, looking for desperate homeowners. Some do passable work. Many do terrible work. Almost none carry insurance or stick around to fix problems.

Legitimate tree companies don’t knock on doors. They’re too busy answering calls from existing customers and referrals. They have more work than they can handle after a storm. They don’t need to canvass neighborhoods.

If someone shows up unsolicited, get their information and tell them you’ll call if interested. Then check reviews, verify insurance, and compare their price to established local companies. The urgency they create is manufactured. Your tree will still be there tomorrow.

Demands Large Deposits or Cash Only

A reasonable deposit for tree work is 10 to 30 percent, paid after you’ve signed a written contract. This covers the company’s scheduling commitment and initial costs.

A demand for 50 percent or more upfront is a warning sign. So is cash only. Scammers want untraceable payment before they disappear. Legitimate businesses accept checks, cards, and digital payments. They create paper trails because they plan to stand behind their work.

The rest of the payment should come after the job is complete and you’ve inspected the work. Any company that demands full payment before finishing has no incentive to do the job right.

No Written Estimate or Contract

A verbal quote means nothing. Get everything in writing.

The estimate should describe the work in detail. Which trees are being removed or pruned. What happens to the debris. Whether stump grinding is included. The total price and payment terms.

Vague language like “remove trees in backyard” invites disputes. Specific language like “remove 45-foot red oak behind garage, grind stump to 6 inches below grade, haul all debris” leaves no room for confusion.

If a company won’t put their quote in writing, they’re leaving room to change the price later. That’s not a company you want on your property.

Recommends Topping Trees

Topping is the practice of cutting the main branches back to stubs. It’s the worst thing you can do to a tree. It destroys the tree’s structure, invites decay, and triggers a flush of weak regrowth that’s more dangerous than the original branches.

Any company that recommends topping doesn’t understand basic tree biology. They might call it “hat-racking” or “heading back” or “reducing the crown.” The result is the same. A butchered tree that will cost more to maintain or remove down the road.

Proper pruning removes selective branches back to the trunk or a lateral branch. It preserves the tree’s shape and health. If the person giving your estimate doesn’t know the difference, find someone who does.

Uses Climbing Spikes for Pruning

Climbing spikes are metal points strapped to an arborist’s boots. They dig into the bark for grip while ascending. They’re appropriate for removals, where the tree is coming down anyway.

They’re never appropriate for pruning a tree you want to keep. Every spike hole wounds the tree and creates an entry point for disease and insects. A pruning job done with spikes leaves hundreds of punctures up and down the trunk.

Professional arborists use ropes, harnesses, and friction hitches to move through a tree without damaging it. If you see spikes come out for a pruning job, stop the work immediately.

No Reviews or Only Perfect Reviews

Check Google, Yelp, and the Better Business Bureau. A company with no online presence might be new, or might be operating under a new name after burning their reputation.

A company with dozens of five-star reviews and zero negative feedback might be buying reviews. Real businesses have occasional complaints. What matters is how they respond. A company that addresses problems professionally and makes things right is more trustworthy than one with a suspiciously perfect record.

Read the negative reviews carefully. Look for patterns. Multiple complaints about the same issue tell you something meaningful about how that company operates.

Pressure to Decide Immediately

A legitimate company gives you a quote and lets you think about it. They know good work speaks for itself. They’re confident you’ll call back.

A scammer pressures you to sign today. The price is only good right now. They have a crew in the area that can start this afternoon. They’re running a special that ends tonight.

High-pressure sales tactics exist to prevent you from comparing quotes, checking references, or thinking clearly. Take your time. Any company that won’t let you is hiding something.

What Good Looks Like

A trustworthy tree company shows up on time for the estimate. They walk the property with you and explain what they recommend and why. They provide a detailed written quote within a day or two. They carry insurance and prove it without hesitation. They answer questions directly. They don’t push you to decide on the spot.

They might not be the cheapest option. But when a 60-foot tree is hanging over your house, cheap isn’t the priority. Competent, insured, and reliable is.

Do your homework before the tree comes down. It’s easier than dealing with the aftermath of a bad hire.
