Tree Service Subcontracting: Sub the Job Out or Turn It Down?

A tree service owner gets a call on a 70-foot oak leaning over a neighbor’s garage. No crane, no operator, and a homeowner holding a quote he wants signed this week. Sub it out, or turn it down?

Most owners sub it, feel good about saving the revenue, and never run the arithmetic on what they kept.

Tree service subcontracting is the reflex answer to a job you can’t perform. It’s also, on a lot of jobs, the option that pays the least of the three available to you.

The Three Options on Every Job You Can’t Perform Yourself

There are not two choices here. There are three, and owners routinely skip the middle one.

Option	What you’re actually buying	What you keep	Where it goes wrong
Sub the whole job out	Another company’s crew and equipment	Their price subtracted from yours	They meet your customer, you own the warranty
Rent the machine, run your own crew	Reach or capacity for one day	Most of the job margin	Your rigging has to be good enough
Turn it down	Nothing	Nothing	The competitor who takes it also quotes the neighbor

Renting is the option that disappears from the conversation, and it’s usually the one with the best math.

Why does it disappear? Because “I don’t have a crane” and “I can’t do that pick” feel like the same sentence when you’re standing in a driveway. They aren’t.

The Tree Service Subcontracting Math Nobody Runs Before Saying Yes

Let’s take the oak. Say you quote it at $6,500, which is in range for a crane-assisted removal over a structure.

Sub it out. The company with the crane quotes you $4,600 to do the whole job. You keep $1,900, minus your drive time, your quote time, your office processing the payment, and a warranty you’re carrying on work you didn’t touch.

Rent the crane and run it yourself. ArboStar’s 2026 crane cost analysis puts rental with an operator at roughly $150 an hour with a four-hour minimum, about $1,200 for a typical crane day, plus a $300 to $800 mobilization fee once the machine travels more than 30 to 40 miles. Your own crew covers the rest. The Bureau of Labor Statistics put the May 2025 median hourly wage for tree trimmers and pruners at $24.50, so three people on a ten-hour day is $735 in base wages before the burden you already know your own number for.

Crane, wages, fuel, and disposal land that job’s direct cost somewhere in the $2,500 to $3,000 range. You keep roughly twice what subbing it out paid.

Turn it down. Zero. And the company that takes it is now parked on that street for two days with a crane, in front of every neighbor who’s been eyeing their own dead maple.

Path on a $6,500 crane removal	Rough direct cost	Rough gross kept	Who the homeowner remembers
Sub the whole job	$4,600	$1,900	The other company’s crew
Rent crane, self-perform	$2,500 to $3,000	$3,500 to $4,000	Yours
Turn it down	$0	$0	Whoever took it

Run those numbers with your own costs before the next one comes in. The gap between row one and row two is the real price of the reflex.

When Tree Service Subcontracting Is Actually the Right Call

None of that means never sub. It means sub for the right reason.

The question isn’t whether you own the machine. It’s whether what you’re missing is equipment or judgment.

A crane you can rent. The experience to call picks on a trunk section hanging over a slate roof you cannot rent, and the day you find that out is the worst possible day to find it out. Missing equipment is a purchase order. Missing skill is a subcontract, or a decline.

What you’re missing	What it really is	Best path	Honest note
A crane, rigging experience is solid	Equipment	Rent with operator	Keeps most of the margin
Rigging judgment on that size pick	Skill	Sub it out	Pay for the judgment, don’t fake it
A stump grinder	Equipment	Sub it, mark it up	Small ticket, real margin, easy to coordinate
Bucket reach on a street tree	Equipment	Rent the bucket	Cheaper than a sub on a half-day job
Line clearance near energized primaries	Certification and law	Decline and refer	Not a margin question
Excavation or land clearing	A different trade	Sub or refer out	Covered in land clearing marketing

Stump grinding is the one most owners under-sub. If you don’t own a grinder, a trusted grinding sub lets you quote a complete removal instead of leaving the homeowner to hire a second company, and standalone grinds are a real revenue line on their own, which we broke down in stump grinding marketing.

And the crane decision specifically has a break-even you can calculate, not guess at. ArboStar’s analysis puts all-in ownership around $5,000 to $7,000 a month and break-even at roughly one full day a week of steady crane work. We walked through how to build that volume on purpose in how to get more crane tree removal jobs.

The Paperwork That Decides Whether You Keep the Margin

Here’s where thin subcontract margin goes to zero.

The homeowner signed with you. Your name is on the contract, your truck was in the driveway, and when a sub’s cut section finds a sunroom, the homeowner is calling you. Not them.

So the certificate of insurance is not filing. Get a current COI, confirm general liability and workers’ compensation are both live, and get your company named as additional insured. Call the carrier on the certificate if the job is big. A lapsed policy you never checked turns their accident into your claim.

Then there’s classification, which quietly bites small tree services every year. The IRS weighs behavioral control, financial control, and the type of relationship to decide whether somebody is a contractor or an employee, and treating an employee as a contractor without a reasonable basis makes you liable for the employment taxes.

A real sub shows up with his own truck, his own crew, his own insurance, and a scope. A climber you schedule, supervise, and hand a saw to is an employee who happens to send invoices. The paperwork doesn’t decide that. The control does.

Write a one-page scope on every sub job: what’s coming down, what’s getting hauled, what’s getting ground, who cleans up, and when payment lands. Thin margin plus a scope argument equals a loss.

Who Owns the Customer After the Sub Drives Away

This is the cost that never shows up on the job sheet.

The homeowner watched somebody else’s crew work for two days. They saw their truck, their shirts, their skill. If that crew was good, the homeowner now has two tree companies in their phone, and one of them actually did the work.

That matters more than it sounds like it does, because repeat and referral work is where tree service margin actually lives. You paid to get that call, you paid your quote time, and then you handed the relationship to a company that competes with you.

There are ways to blunt it. Be on site for the pick. Send the follow-up. Own the warranty call. But you can’t fully undo it, and on a steady diet of subbed work you’re slowly building somebody else’s reputation in your own service area. The follow-up mechanics that keep a customer yours are in tree service lead follow-up.

Turning Work Down Is a Capacity Decision, Not a Weakness

Now the other direction, because plenty of owners sub jobs they should simply decline.

Subbing a job you shouldn’t have quoted doesn’t fix the quote. It buys a thin margin, a coordination headache, and a liability you carry for a year. On a $900 job with a $750 sub cost, you’re working for $150 and a warranty. Decline it, refer it, and spend the afternoon quoting work you can actually perform.

What makes that comfortable? Call volume. Nobody turns down work when the phone has been quiet for nine days.

That’s the honest connection between capacity and marketing, and it runs the opposite direction from how most owners think about it. They sub out of scarcity, not strategy. Fix the scarcity and tree service subcontracting becomes a margin calculation instead of a panic. The same logic decides when to add a truck, which we covered in when to buy a second truck.

Change the Job Mix and the Problem Shrinks

Here’s the part nobody tells you: the ratio of jobs you can’t perform isn’t fixed. It’s a result of where your marketing lands and what it says.

Crane jobs cluster. A 1970s subdivision where the builder planted silver maples is a street full of removals maturing at the same rate, with tight lot lines that make them crane work. A 2015 build with ornamental pears will never produce one. If you’re mailing both, you’re paying for calls you’ll end up subbing.

So pick the routes on purpose. Every carrier route we score carries 295 data points including satellite tree density, which is how a street of 70-foot oaks gets separated from a street of lawn. Then the letter names the work you want, because a mailer that says “that dead limb over your driveway” pulls removals and a generic one pulls price shoppers.

Abraham Adams with Westwood Tree Service grew his income by $10,000 to $15,000 a month with consistent direct mail. Income, not revenue, which is the whole point of this article: subbed revenue and owned revenue are not the same money.

The mechanism underneath is measurable and boring. Every route gets its own tracking phone number, so the call log says which neighborhoods produced work and which didn’t. Across 250+ tree service companies, our internal data shows roughly 75% of calls come from about 50% of the routes mailed. Cut the quiet half, scale the loud half, and the job mix tightens along with the cost. Pricing runs $0.52 to $0.70 per letter depending on volume.

For context on the channel, the 2025 ANA/DMA Response Rate Report puts the average direct mail response rate at 4.4% across industries, and that figure leans on mail to existing customers, so cold saturation mail runs below it. The comparison that matters is your routes against each other. The full argument is on why direct mail works for tree services.

Run Your Own Numbers Before the Next Big Oak

Subbing out a job you can’t perform isn’t wrong. Subbing it out without checking whether a rental would have paid double is.

So build the short list now, before the phone rings: what you’ll rent, what you’ll sub, what you’ll decline, and what each one keeps. Then work on the input instead of the symptom, because a pipeline full of work your crews can actually perform beats a pipeline you have to hand to somebody else.

Book a 15-minute call and we’ll pull the carrier routes around your shop, show you the tree density and household income on each one, and tell you which neighborhoods produce the removals you can do with your own people. If the data says your market won’t support it, we’ll tell you that too.

Your move.
