Why Hiring the Right Arborist Matters
Tree work is physically dangerous and technically complex. An unqualified operator can damage or kill your trees through improper pruning, misdiagnose disease, or — in the worst cases — cause serious injury or property damage through unsafe work practices. Finding a genuine professional protects both your trees and your home.
What Is a Certified Arborist?
The most widely recognized professional credential in the tree care industry is ISA Certification, issued by the International Society of Arboriculture (ISA). An ISA Certified Arborist has passed a comprehensive exam on arboricultural science and practices and must earn continuing education credits to maintain their certification.
You can verify an arborist's current ISA certification status through the ISA's online directory at treesaregood.org. This is a simple step that filters out a large number of unqualified operators.
Additional credentials worth noting:
- ISA Board Certified Master Arborist (BCMA): The highest ISA credential, requiring extensive experience and advanced examination.
- TCIA Accredited Company: The Tree Care Industry Association accredits companies that meet defined standards of professionalism and safety.
- Licensed arborist (state-specific): Some states require licensing beyond ISA certification — check what your state mandates.
Essential Questions to Ask Before Hiring
About Qualifications and Insurance
- "Are you ISA certified? Can I see your certificate or look you up on the ISA directory?"
- "Do you carry both liability insurance and workers' compensation coverage?" (Request certificates of insurance directly — don't just accept verbal assurances.)
- "How long have you been providing tree care services professionally?"
About the Work
- "Can you explain exactly what work you're recommending and why?"
- "What will you do to protect my property and surrounding plants during the work?"
- "Who specifically will be doing the work — you, or a crew? Are they trained?"
- "What will happen to the debris — is removal included in the quote?"
About the Quote
- "Can I get this quote in writing?"
- "What exactly is and isn't included in this price?"
- "Is stump removal included, or priced separately?"
Red Flags to Watch For
| Red Flag | Why It's a Problem |
|---|---|
| Door-to-door solicitation after a storm | Classic sign of an unqualified "storm chaser" operation |
| Asks for large cash payment upfront | Professional companies rarely require full payment before work |
| No proof of insurance | You could be liable for injuries on your property |
| Recommends "topping" the tree | Topping is harmful and rejected by professional arborists |
| Unable to explain why work is needed | Suggests lack of expertise; they may be creating unnecessary work |
| Pressures you to decide immediately | Legitimate professionals give you time to get multiple quotes |
Get Multiple Quotes
For any significant tree work, get at least two or three written quotes. Prices can vary considerably, and comparing quotes also helps you evaluate how well each company communicates and whether their recommendations are consistent. If one quote recommends removal and another recommends treatment, dig into that discrepancy — it's informative.
Understanding Cost Factors
Tree service pricing varies based on several factors, including:
- Tree size and species
- Proximity to structures, power lines, or fences
- Accessibility for equipment
- The scope of work (pruning vs. full removal vs. emergency work)
- Local market rates
Be wary of quotes that seem dramatically lower than others — they often reflect missing insurance, unlicensed workers, or planned shortcuts that could harm your trees or your property.
