When should I call an arborist instead of a removal company?
Call an arborist when you need a diagnosis, an answer on whether the tree can be saved, a risk rating for a leaning or cracked tree, advice before building near roots, or documentation for insurance or a dispute. A visit costs $75–$150. Call a removal company when the tree is plainly dead or you have decided to remove it.
The rule is short: call an arborist when the job starts with a question, and a removal company when it starts with a decision. Many homeowners get this backwards and end up acting on advice from the person who profits if the tree comes down. The table lists the common situations and the right first call for each.
| Situation | First call | Why | Typical cost of that call |
|---|---|---|---|
| Tree looks sick; you want to keep it | Arborist | Many causes are treatable and cheaper than removal | $75–$150 visit |
| New or increasing lean, cracks, lifted roots | Arborist (same day if it leans toward a target) | Needs a risk rating, not a price | $75–$150; $150–$500 written |
| Building, paving, or trenching near a tree | Arborist, before the contractor starts | Root damage kills trees years later | $75–$150; more for a protection plan |
| Insurance claim, neighbor dispute, HOA, city hearing | Arborist with TRAQ or consulting credential | Third parties act on documents | $150–$500 report; $300–$1,000+ formal |
| Buying a house with large trees | Arborist during the inspection period | Only window to negotiate a dying tree into the price | $75–$150 |
| Tree is plainly dead or already down | Removal company | Nothing to diagnose | Free quote; removal $200–$2,000 |
| Healthy tree you want gone for space or light | Removal company, after a permit check | It is a choice, not a diagnosis | Free quote |
Should I call an arborist if my tree looks sick?
Yes, when two things are true: you would rather keep the tree, and it is big enough that removal costs real money. A thinning crown, dead limbs on one side, early leaf drop, small leaves, mushrooms at the base, or bark that is oozing or peeling can each come from several causes. Some are treatable, such as an insect problem caught early, compacted or waterlogged soil, or a girdling root strangling the trunk. Some are not, such as major root rot or a hollow trunk. A $75–$150 arborist visit tells you which. Where the line falls is on can an arborist save my dying tree? and, for the diseases themselves, common tree diseases. If it has no leaves in summer and the branches snap dry, skip the visit; see how to tell if a tree is dead.
Should I call an arborist about a leaning tree?
If the lean is new, has gotten worse, or points at a house, driveway, or play area, yes, and call the same day if you see soil heaving or cracking on the side away from the lean, because that is the root plate letting go. Arborists get concerned past about 15 degrees from vertical, but the angle matters less than the trend. A tree that has leaned the same way since it was planted, with a trunk that curves back to vertical and no soil movement, is usually stable and just looks alarming. An arborist can rate the risk in a written assessment for $150–$500 if you need to show a neighbor or an insurer. The thresholds and what to look for are on is a leaning tree dangerous?
Do I need an arborist before building near a tree?
If you want the tree alive in five years, yes, and before the contractor breaks ground, not after. Trees die from construction slowly: a trench through the roots for a footing or a utility line, a new driveway compacting the soil, grading that buries the root flare or strips the topsoil. The tree looks fine the year of the build and is dead in two to five. Called early, an arborist can mark a root protection zone, tell the contractor where to tunnel instead of trench, and specify fencing to keep equipment off the roots. That advice costs $75–$150 for a visit, more for a written protection plan a permit office may require. Roots near a house raise their own set of questions, covered on tree roots near the foundation.
Do I need an arborist report for insurance or a dispute?
Usually. The moment someone other than you has to act on the opinion, it needs to be written and signed by a credentialed person. A neighbor who wants your tree gone, or whose tree you are worried about, will respond to a written risk assessment in a way they will not respond to a removal company's quote. An insurer deciding whether a tree that fell was a known hazard wants documentation from before the storm. A city permit office may require an assessment before approving removal of a protected tree, and a court will want an appraisal from a consulting arborist if the tree's value is in dispute. A written report runs $150–$500; a formal risk assessment by a TRAQ-qualified arborist or an appraisal by an ASCA Registered Consulting Arborist is $300–$1,000+. Which credential does what is on what is an ISA Certified Arborist?
When should I skip the arborist and call a removal company?
When there is nothing to diagnose. A tree that is clearly dead, a tree that has already fallen, a small tree that costs $200–$500 to remove, or a healthy tree you have decided to remove for light, space, or a building project: in each case the arborist can only tell you what you already know. Go straight to a written quote from a vetted removal company, confirm its insurance, and check whether your city requires a permit for a tree of that size. Costs for each level of advice, and when the fee pays for itself, are on how much does an arborist consultation cost?
