Tree Service Estimate Came In Too Low: Fix It Before the First Cut

Short answer: A tree service estimate came in too low usually because it was priced on height and trunk diameter when the hours are set by access. A 70-foot pine felled whole in an open field is one unit of work; the same tree rigged down over a roof in 40-pound pieces is a different job entirely. Reprice from the measured drop zone, count the rigged pieces, and get any change order approved before the first cut — once the top is out, walking away stops being an option.

Most trades get a second chance at a bad number. A painter who does the math on Tuesday morning can stop, have the conversation, and leave a room that still has walls. Tree removal does not work that way, which is why the entire correction window for a short bid sits in the twenty minutes before the climber ties in. The general fields on the bill are covered in what to include on an invoice; this is about the arithmetic that produced the number in the first place.

Why does a low tree estimate stop being fixable after the first cut?

Because there is a point of no return, and it arrives early.

Once the top is out of a 70-foot silver maple, what is standing is not a tree. It is a spar with a changed load path, leaning over somebody’s garage, and it is your liability until it is on the ground. You cannot pack up. You cannot come back Thursday. The customer cannot get a second quote. Every option you had at 7 a.m. is gone by 9:30, and the only remaining path is through.

That single fact reorders the priorities for this trade. In most estimate-too-low situations the useful advice is about how to stop and renegotiate. Here, the useful advice is about the walk you do before you unload — because the cost of a bad number is fixed the moment the saw starts, and the only thing left to fix is the method that produced it.

Which number was wrong, the height or the access?

Almost never the height. Height sets the class; access sets the hours.

What you are seeing on site	What went wrong in the bid
Every piece is going down on a rope	Drop zone assumed rather than measured
Two hours gone before the first cut	Tarping, plywood, moving the customer’s cars and patio furniture
Groundmen walking brush 120 feet to the chipper	Drag distance and chipper placement never counted
The bucket never made it to the back yard	Gate width, soft ground, or a fence section that had to come out
The climber refused to spike it	Sold as a prune, priced as a removal — you cannot spike a tree that is staying
Wood still in the yard at four o’clock	Disposal treated as a wave-off instead of as tonnage
Crew standing while a utility truck is dispatched	Conductor inside the approach distance
Stump took as long as the tree	Grinding priced per stump instead of by grade diameter and depth
A chain destroyed on the second cut	Hardware in the wood — clothesline, fence wire, an old lightning cable

Two of those carry most of the losses.

The drop zone is the priced unit, not the tree. Stand at the trunk and measure the clear radius in feet in four directions, then write down the closest hard object in each. A tree with roughly one and a half times its height of clear space on the fall side is a felling job: one notch, one back cut, and the rest is cleanup. A tree with fifteen feet in every direction is a piecing job, and piecing is counted in cuts, not in feet of height. The same species, the same diameter, the same 70 feet — and the second one holds a three-person crew for most of a day.

A dead stem changes the class, not just the risk. A dead, hollow, or storm-damaged tree cannot be climbed, and that is not a judgment call your climber gets to make on the day. It becomes a bucket job. If the bucket cannot reach the base, it becomes a crane pick, and cranes come with a minimum and a day rate that does not prorate down when you finish at two o’clock. Bidding a dead tree as a climb is the single most expensive misclassification in this trade.

How do I count a removal in pieces instead of feet?

Walk it and count cuts. This takes about ten minutes and it replaces the entire guess.

1. Mark the clear radius in four directions from the trunk, in feet, and name what is inside each one — roof, fence line, septic field, pool, irrigation heads, gravestones, a greenhouse.
2. Decide the largest piece you are allowed to let fall, and where it lands. If the answer is “nothing larger than what a groundman can carry,” you have a rig-down.
3. Count the crown in two buckets: limbs that can be dropped free, and limbs that must be tip-tied and lowered. A lowered piece is a three-person operation — climber sets it, one runs the rope, one clears the landing — so it eats crew time, not climber time.
4. Count the trunk blocks, and decide whether each one stays where it lands or has to be rolled, winched, or picked out.
5. Put your own cycle time on a rigged piece. Time five of them on the next job with a stopwatch. That number, multiplied by the count, is the honest labor line.

Access class	What defines it	What it does to the day
Open drop	Clear fall path well beyond tree height, truck reaches the base	One notch, one back cut, then cleanup
Yard drop	Open in the middle, obstacles at the edges	Sectional felling, occasional rope
Rig-down	House, fence, or shed inside the drip line	Every piece tied, lowered, and landed by hand
Crane pick	No lowering path, or a stem that cannot be climbed	Day-rate crane, possible street permit and traffic control
Line clearance	Energized conductor inside the approach distance	Not your decision — qualified crew and utility coordination

That last row is regulatory, not optional. Under OSHA 1910.333(c)(3), unqualified workers must stay at least 10 feet from overhead lines at 50 kV and below, with the distance increasing above that. Work closer than that requires line-clearance qualified employees. A bid written without looking up is a bid that may not be legal for your crew to perform.

What does the wood do to the number after the tree is down?

It splits into two disposal streams with two different units, and most short bids only priced one of them.

Chips move by volume: chipper feed, chip truck capacity, and how many trips back to the yard or the dump. Wood moves by weight: rounds and trunk blocks that will not go through the chipper, loaded onto a trailer or picked with a grapple, and tipped at a facility that charges by the ton. Green wood is heavy and the weight per volume swings hard by species and season, which is why the only reliable source for this line is your own stack of scale tickets rather than any published table.

The discount for leaving the wood is real, but read it carefully. “Leave the rounds where they fall” removes loading, hauling, and a tipping fee, and it is worth money. “Stack it neatly by the shed” removes the tipping fee and adds labor, and it is worth much less than customers assume. Say which one you are pricing, in a sentence, on the estimate.

Why does stump grinding refuse to sit inside the tree price?

Because it is a separate machine, a separate mobilization, and a unit that has nothing to do with the tree that used to be there.

Grinding is priced from the diameter measured at grade — not DBH, which is measured higher and is always smaller — times the depth you agreed to go, plus surface roots, which on a mature maple can add more grinding than the stump itself. The output is the part that surprises people: a ground stump produces far more chip volume than the stump occupied, because you are turning solid wood into shavings and mixing in soil. Haul-away and backfill are a separate line again.

Two things belong on the estimate every time. Depth is a priced choice, and the customer has to make it: shallow enough to put turf over, or deep enough to replant. And a utility locate is required before you put a grinder in the ground — call 811 and wait for the marks, because an irrigation line is an annoyance and a gas service is a different kind of day.

How do I rebuild a per-tree price from my own cost, and is that markup or margin?

Build it from the crew up, in one pass, and use your own numbers.

1. Loaded crew cost per hour. Wages for everyone on the truck plus payroll taxes and workers’ comp. Pull the comp rate off your own policy rather than assuming — the climbing classifications are among the heaviest in any trade, and using a generic burden factor understates the crew line badly.
2. Equipment per hour. Chipper, chip truck, bucket, grinder, and the consumables that actually move: bar oil, chains, wedges. Climbing line and saddle retire on a date whether or not they look worn, so they are a recurring cost, not a purchase.
3. Mobilization as a fixed block. Setup, tarps, plywood over the lawn, moving vehicles, the tailgate briefing, and the final blow-off. It happens on every job regardless of tree size, and it punishes small trees.
4. Cycle time times piece count from the walk above.
5. Disposal as measured tonnage and chip loads, from your tickets.
6. Crane or lift at its quoted rate, plus your own crew’s standing time while it sets up.
7. Overhead per billable crew hour — total the year’s insurance, licensing, storage, phone, and estimating time, then divide by billable hours, not by 2,080.
8. Then profit, which is where the arithmetic usually goes wrong.

Say a tree costs you $1,400 all in. Add 35 percent markup and you charge $1,890. Your margin is $490 ÷ $1,890, which is 25.9 percent — not 35.

Cost per tree	Add 35% markup	Resulting margin	Price for a true 35% margin
$900	$1,215.00	25.9%	$1,384.62
$1,400	$1,890.00	25.9%	$2,153.85
$2,600	$3,510.00	25.9%	$4,000.00

Nine points, on a job that ties up a three-person crew, a chipper, and a truck for a day. Pick which word you mean, write it on the pricing sheet, and use it every time. Published per-tree ranges are worth a sanity check and nothing more — they swing hard with region, species, storm season, and how much crane work your market expects — and if your build lands far outside one, the answer is usually something specific about your access class or your disposal, not a math error.

How do I write a change order with a climber already in the tree?

Rarely, at a defined pause point, and in writing before anything else moves.

There are legitimate mid-job triggers, and they are almost all discoveries you could not see from the driveway: a cavity or a rotten core visible only from thirty feet up, an included-bark union that changes the rigging plan, a hanger left by a previous storm, metal in the wood, an irrigation system or septic field nobody mentioned, or a customer who adds “and the one behind it while you’re here.”

The note is four sentences and it goes out from the truck: name the discovery, state the method change, give the price, and say that work is paused pending approval. A photo of the cavity, a number, and a reply of “yes” is a written change order. A shouted conversation from the base of the tree is not, and it will not exist in November.

The pause points are physical and you should know them before you start. You can stop after the crown is off and before the spar comes down. You can stop between the tree and the stump. You cannot stop in the middle of a spar, and you cannot stop with a limb tied off over a roof. Plan the conversation for a point where the tree is stable.

When is finishing a tree at a loss the right call?

Usually, and for a reason that has nothing to do with goodwill.

A half-finished removal is a hazard you own. The fastest and cheapest exit from a tree you mispriced is almost always to finish it, because the alternative is leaving a compromised stem over a structure and carrying that risk while you argue. Absorb it, log the real cycle times, and fix the method that produced the number — which usually means every bid you wrote that week shares the defect, since they came out of the same habit.

The exception is not a pricing conversation at all. If the tree turns out to be something your crew is not qualified or equipped for — an energized conductor inside the approach distance, a stem that needs a crane you did not plan for, a lean you cannot control — that is a stop-work, and it happens before the climb, not after. Refer it out, bill nothing, and keep the relationship. Storm work is its own category here: emergency response prices well above a scheduled removal because the tree is already failed, the load path is unknown, and the crew is working on somebody else’s timeline. Bidding storm work at catalog prices is how a good week turns into a bad month. When the customer disputes the number afterward, the habits in how to get clients to pay matter more than the argument itself.

What has to be recorded so the next bid is arithmetic?

Three things per tree, captured on the phone before you leave: the measured drop zone by direction, the piece count and cycle time, and the disposal tickets. That file is what turns next season’s estimate from an opinion into a calculation.

Keel handles the money side of that without adding an office. It is an iOS app that runs entirely on the device — no account, no bank connection, no cloud, no login — with an App Store privacy label that reads Data Not Collected. The change-order invoice for the second tree goes out from the truck in about a minute with your own numbering, logo, brand color, and a payment link as a QR code. Scale tickets, chip dump receipts, and the saw shop invoice get photographed and read on-device with Apple Intelligence, so the disposal line has paper behind it next time you bid the same species. The drive between the yard, the job, and the transfer station logs as mileage, which on a truck-and-chipper operation is not a small deduction — see how to track mileage for taxes. Freeboard shows cash minus tax reserve, committed invoices, and buffer, which in a trade with a storm-driven revenue curve is the number that tells you whether a busy month was a good one. The year exports as a single file, or as the Accountant Pack: a CSV plus a one-page summary PDF, on top of an append-only hash-chained ledger. Free is $0 with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription. What is deductible on the equipment side is covered in self-employed tax deductions.

Frequently asked questions

Why do tree removal estimates come in too low so often?

Because they get priced on what you can see from the driveway — height and trunk diameter — when the hours are set by access. The same 70-foot tree is a one-notch fell in an open field and a full day of rigging when a garage sits inside the drip line. Measure the clear drop radius in four directions and count the pieces that have to be lowered.

Can I raise the price after I have started taking a tree down?

Only for a genuine discovery, only at a point where the tree is stable, and only in writing before the next cut. A cavity found on the climb, metal in the wood, or an undisclosed septic field are real change orders. Your own underestimate of the rigging is not, and once the top is out, you own the stem until it is on the ground.

Should stump grinding be included in the tree removal price?

No. It is a separate machine, a separate setup, and a different unit — diameter at grade times the depth the customer chooses, plus surface roots, plus a chip volume much larger than the stump was. Quote depth as an explicit choice, price haul-away and backfill separately, and get an 811 locate before the grinder goes in the ground.

How should a dead tree be priced differently from a live one?

As a different access class, not as the same tree with a risk premium added. A dead or hollow stem should not be climbed, which means it is a bucket job, and if the bucket cannot reach the base, it is a crane pick with a day rate that does not prorate. Establish which of those it is during the walk, before you write a number.

What does the customer keeping the firewood actually save me?

Less than they think, unless the wood stays where it falls. Leaving the rounds in place removes loading, hauling, and the tipping fee, and that is worth real money. Stacking it neatly by the shed removes only the tipping fee and adds labor, so it may cost you more than hauling it out. Write which version you priced.

How should storm work be priced against a scheduled removal?

Well above it, and for structural reasons rather than opportunism. A failed tree has an unknown load path, is often under tension against a structure or a line, and the work happens outside normal scheduling with crews already committed elsewhere. Price the emergency response, access, and risk as their own lines so the customer sees what the premium is buying.
