The short answer
If this is happening now: Stay away from any tree, limb or wire touching a power line, and call your utility. Treat a downed line as live and call 911.
A tree on a house, car or fence is a job for a tree company with the right insurance, not for anyone with a ladder or a chainsaw.
Tree work is priced by risk and access, not by the amount of wood.
You are paying for a crew that can bring weight down near a roof or a line without dropping it on either, insured so a fall on your property is not your liability.
ANSI A300 covers how the work is done and ANSI Z133 covers crew safety.
What should you know before you hire tree work?
Anything touching or near a line is for the utility or a line-clearance crew to handle. Keep yourself and everyone else away.
Cutting a crown back to stubs forces fast, weakly attached regrowth. In a few years the crown is back, and less securely joined.
In our tree removal permit study, 11 of 23 cities require a permit to remove some trees on private lots. Check before agreeing a date.
Ask for general liability and workers’ compensation certificates, sent by the insurer rather than the company.

Free, with no obligation: a person at HyreYard replies by email. Matching is not live yet, so this is not a quote. If a tree or limb is on a power line, stay away and call the utility.
What should you note before anyone visits?
None of these is a diagnosis, and a photo is not an assessment. They are worth writing down from the ground, because some vanish once the leaves are out.
A structural finding worth having assessed rather than guessed at.
Co-dominant stems. The join can be weaker than it looks, especially with bark trapped inside.
Signs of decay in wood that holds the tree up.
Especially over a driveway, path or seating area. The easiest pruning to scope honestly.
Clearance questions, and near a service line the utility’s question first.
The root plate is moving. That is a lean happening now, not one the tree grew with.
No visible flare where the trunk widens into roots. Penn State Extension: “air may not penetrate the mulch layer and the underlying soil becomes depleted of oxygen.”
A whole-tree signal. Look at the roots and recent changes on the site before anything is cut.
Is it pruning, topping or removal?
These get quoted as different amounts of one job. They are different jobs, and the lowest line on a bid may not be pruning at all.
| Work | What it is |
|---|---|
| Structural or crown pruning | Selected branches removed for clearance, deadwood or structure, cut back to a point the tree can close over. Slow and skilled. |
| Crown cleaning | Dead, broken and diseased wood only. Easy to check afterward, because you can see what is gone. |
| Topping | The crown cut to stubs at an arbitrary height. It leaves large wounds and forces dense regrowth that is weakly attached. |
| Lion-tailing | Inner foliage stripped, tufts left at branch ends. It moves weight and wind load to the end of each limb, and is sometimes sold as thinning. |
| Removal | Taking the tree down, in sections when anything sits beneath it. Different rigging, insurance and permit questions. |
| Stump grinding | A separate machine and line item. Ask the depth and what happens to the grindings. |
| Root pruning for construction | Cutting roots for a patio, wall or trench. It can kill a tree years after the paving went in. |
What should a tree company check before quoting?
A quote from a photo has priced the wood, not the job. These need a visit.
A dead limb over lawn and the same limb over a glass roof are different jobs at different prices.
Work near energized lines is regulated and needs qualified crews. Sometimes the utility must attend first.
Whether a lift or crane can reach, or the crew must climb and lower piece by piece.
Mulch or soil pulled back so the root flare is visible.
By species, trunk diameter, location on the lot or protected status. See the tree removal permit study.
Chipped on site, hauled away, or left as rounds. Different prices, and worth agreeing rather than assuming.
Some species have seasons when cutting invites disease. “Any time is fine” for everything is a warning sign.
A tree too big for its spot can call for removal and a replacement rather than repeated cutting.
What does tree work involve?
A tree day is mostly setup, rigging and cleanup. The cutting is the short part, and not where the price or the risk lives.
Which trees, what work on each, and why. “Trim trees” is not a scope, and tree work cannot be put back.
Where removal is regulated, the permit comes before booking. Any work near a line is arranged with the utility first.
Cones, ropes, plywood over paving, cover for beds and sprinkler heads, and a marked drop zone nobody enters.
A trained climber on rope, or an aerial lift. The choice follows access, the wood’s condition and what is below.
Where nothing can drop freely, pieces are cut and lowered on ropes. It is the slow, costly, skilled part a lowball bid leaves out.
At a branch union or collar so the tree can seal the wound, not at a convenient height. The difference shows for years.
Chipping, hauling, stump grinding if agreed, raking and a final walk. Agree in writing what “cleanup” means.
Mulch 2 to 4 inches deep, kept off the trunk. Water a tree that has just lost roots or crown.
How much mulch goes around a tree?
Mulch is the one landscape material where more makes the outcome worse, and the damage is slow enough that nobody connects it. These are Penn State Extension’s figures.
| Rule | Penn State Extension |
|---|---|
| Depth | “Apply a 2- to 4-inch layer of organic mulch and no more; use less if the soil is poorly drained.” |
| Fine or double-shredded | “If using finely textured or double-shredded mulch, use 1 to 2 inches since these materials allow less oxygen through to the root zone.” |
| Gap at a young trunk | 3 to 5 inches. |
| Gap at a mature trunk | 8 to 10 inches. |
| Why piles harm | Piled deep, “air may not penetrate the mulch layer and the underlying soil becomes depleted of oxygen.” |
Work out how much to buy for a bed or a tree ring with the mulch calculator.
What belongs in a written tree-work scope?
Tree work cannot be undone. A patio can be relaid; a limb cannot be put back. That is why the scope has to be specific before the crew arrives.
Each one identified by tag, photo or sketch. “The trees at the back” has cost people trees they wanted.
Deadwood removal, clearance to a stated distance, named limbs. Not “trim” or “shape.”
Which standard the work follows, and whether the crew is trained to it.
A sentence saying no topping or lion-tailing, if that is what you agreed.
A distance in feet from the roof or drive, not “cut it back.”
Whether any work is near a line, and who contacts the utility.
Who applies, who pays, and what happens if it is refused.
General liability and workers’ compensation certificates, sent by the insurer, dated to cover the work.
Chipped, hauled or left, and whether the stump is ground and how deep.
Beds, sprinkler heads, paving and lawn, and who pays if any are damaged.
On this site, tree work is where the written scope protects something that cannot be rebuilt.
Tree safety comes first
Tree work carries risk of electrocution, falls and crushing. These are the rules for anyone who is not a trained tree crew.
Do not touch, prune or climb any tree near a line, and keep ladders and poles clear. Call the utility; many run line-clearance programs.
Treat every fallen wire as live, keep people and pets back, and do not touch anything it rests on.
Leave felling, climbing and chainsaw work to an insured tree company, even for a small tree.
While a crew works, keep everyone outside the area it has marked off.
A split trunk or hung limb can move without warning. Keep clear and call a tree company.
A grinder cuts below the surface. Call 811 so buried utility lines are marked first.
HyreYard is not a tree service and is not an emergency line. Nothing on this page is advice to do tree work yourself.
What moves the price of tree work?
Tree work is priced on risk and access more than size. The same tree in an open field and beside a glass extension are two jobs, and only one allows dropping wood.
| Factor | Why it changes the number |
|---|---|
| What is underneath | Open ground lets pieces drop. A roof, pool or fence means rigging and lowering everything. |
| Height and spread | Decides whether the tree is climbed, whether a lift reaches, and how many rigging points it needs. |
| Power lines | Changes who may do the work and can add a wait for the utility. |
| Access | Whether a chipper, lift or crane can reach. Carrying through a side gate adds hours. |
| Condition of the wood | Decayed or storm-damaged trees cannot be climbed or loaded like sound ones, so the method changes. |
| The wood afterward | Chipped, hauled with a dump fee, or left as rounds for you. |
| Stump grinding | A separate machine, and sometimes a separate visit. Depth and disposal move it. |
| Storm call-outs | A crew pulled off scheduled work after a storm is priced differently from a booked job. |
| Permit and replanting | Where removal is regulated, fees and required replacement trees belong in the bid. |
HyreYard publishes no national average price for this work. Regional labor, material and disposal rates, access and soil move it far enough that a single figure would mislead.
If one bid is half the others, find out what is missing.
The savings come from a short list: no workers’ compensation, no liability cover, no rigging where it is needed, climbing spikes on a tree that is staying, or topping sold as reduction. None shows on a quote. Ask every company the same questions on insurance, method over the house, topping, wood and permits.
What to ask before you sign
General liability and workers’ compensation, with certificates from the insurer.
And is the crew trained to it?
If so, why, and what is the alternative?
On a tree that is staying rather than coming down?
Dropped, rigged and lowered, or lifted?
Does the utility need to be involved?
Who applies, and is replanting required?
How is a change in scope handled and priced?
What to have ready, from the ground
From two sides and from below, numbered so everyone knows which tree is which.
Mulch pulled back from the trunk so the flare shows. Do this only on a sound tree, well away from any line.
A trench, patio, new drive or regrade. Root damage can show in the crown years later.
Ownership of a trunk on a line, and the right to cut over it, is a legal question.
Whether your city regulates removal, and whether your HOA adds its own rule. The tree removal permit study lists what 23 cities publish.
Decide before the bid; it moves the price.
Where does tree work go wrong?
It leaves large wounds and weakly attached regrowth. In a few years the crown is back, heavier and less secure.
A fall on your property by an uninsured worker becomes your problem. Certificates from the insurer take minutes to check.
Where removal is regulated, enforcement comes after the tree is gone, and nothing puts it back.
Mulch piled against the trunk starves roots of air and keeps bark wet. Keep it 8 to 10 inches off a mature trunk.
Climbing spikes wound the trunk at every step. Fine on a removal; harm on a tree you keep.
Digging and compaction in the root zone damage a tree slowly, so its decline years later is rarely traced to the patio.

Primary-source research, data analysis and fact checking
We are a research desk, not a landscaping company. We read the statute, the municipal code, the water-district rule or the federal soil file ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. This desk is new.
The counts below are what we can already stand behind, and every one of them is counted from the studies on this site.
- 255
- source documents cited, each linked
- 112
- government (.gov) domains among them
- 258
- citations carrying a retrieval date
- 10
- research studies published
How this desk works
- Primary sources only. A rule comes from the statute, ordinance, board or agency that issued it, cited by section, with the URL and the retrieval date. We do not cite a blog that cites a code.
- Coverage is a number. A table titled to fifty states has fifty sourced rows. A table of cities is titled to the cities we actually read. Gaps are published as gaps.
- Company counts stay inside seven states. Texas, Arizona, Washington, California, Oregon, Florida and North Carolina. Texas is the largest roster on the weakest evidence, a self-reported NAICS sales-tax permit, because Texas licenses no landscaper. National claims rest on federal or state agency data, never on our counts.
- Fact, calculation, analysis and recommendation stay labeled. "According to…" is a source. "HyreYard analyzed… and calculated…" is ours. "This suggests…" is interpretation. We do not present our reading as something the source stated.
- We do not landscape, irrigate, plant, cut trees or pull permits, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
