1. Hire an ISA Certified Arborist
When it comes to tree care, expertise matters. Look for an arborist certified by the International Society of Arboriculture (ISA). ISA certification is a mark of a professional who has met rigorous standards in arboriculture. This certification ensures that the arborist is knowledgeable about tree health, safety and proper care techniques. You can verify an arborist’s certification and find a list of qualified professionals in your area by visiting the ISA website.

2. Beware of Door-Knockers
After severe weather events or pest outbreaks, you may encounter door-to-door solicitors offering immediate tree removal services. These door-knockers often use high-pressure tactics to convince homeowners to make quick decisions. Many of these individuals are not certified professionals and may not have the necessary skills or equipment. To avoid potential scams or unsafe practices, always choose a reputable arborist who provides a written estimate and uses proper safety measures.
3. Inquire About Climbing Spikes or Spurs
Climbing spikes or spurs can be harmful to live trees. These tools create holes in the tree's bark, which can lead to infections and pest infestations. Reputable tree care companies will use alternative methods, such as rope climbing systems, to avoid damaging healthy trees. If you’re concerned about the impact on your tree, ask the arborist how they will access the tree and ensure they use techniques that protect its health.

4. Verify Insurance Coverage
Always request proof of both worker's compensation and liability insurance before hiring an arborist. Worker’s compensation covers injuries that occur on the job, while liability insurance protects against damage to property. Contact the insurance providers to confirm that the policies are up-to-date. Without proper insurance, you could be held responsible for injuries or damages caused by uninsured workers.
5. Discuss Wildlife Considerations
Trees are vital habitats for various forms of wildlife. Responsible arborists will inspect the tree for nests or wildlife before starting any work. They should have a plan to avoid disturbing or displacing wildlife and follow protocols to handle any disruptions sensitively. Ensuring the safety of wildlife not only benefits the local ecosystem but also aligns with ethical tree care practices.

6. Request Local References
A reputable arborist should be able to provide a list of local references. Talking to previous clients can give you insights into the company’s reliability, workmanship and customer service. Ask references about their overall experience, the quality of work performed and whether they would recommend the arborist.
7. Educate Yourself on Tree Care
Being an informed consumer helps you make better decisions and ask the right questions. Educate yourself about basic tree care practices, common pests and tree diseases. Resources like the ISA website offer valuable information on tree care and maintenance. Understanding tree care basics will help you communicate effectively with arborists and ensure that you receive the best service.

8. Avoid Rushed Decisions and Bargains
Take your time to make an informed decision. Avoid falling for too-good-to-be-true offers or being pressured into immediate agreements. Obtain estimates from multiple arborists and compare their services, prices and recommendations. Remember, the lowest bid might not always provide the best value. Investing in quality tree care can save you money in the long run by preventing potential issues.
Choosing the right arborist is crucial for maintaining the health and safety of your trees. By following these tips, you can make an informed decision and ensure that your trees receive professional and ethical care. Remember, a well-cared-for tree not only enhances your property’s beauty but also contributes to the overall health of your local environment.
