Choosing Your Arborist

When hiring an arborist, it's important to consider the following factors to ensure you are choosing a qualified professional.


An arborist who maintains a membership in a professional organization, such as the International Society of Arboriculture (ISA), the Tree Care Industry Association (TCIA), or the American Society of Consulting Arborist (ASCA), demonstrates a willingness to stay up-to-date on the latest techniques and information. Certified Arborists are individuals who have achieved a level of knowledge in the art and science of tree care through at least three years of tree care experience, and who have passed a comprehensive examination developed by some of the nation’s leading experts on tree care. Although arborist certification cannot guarantee or assure quality of performance, it can attest to the tree knowledge of an individual. If you have located a tree care professional and would like to verify that their ISA Credential is valid, you can check their certification at

Ask For Proof of Insurance

Pruning or removing trees, especially large trees, can be dangerous work. Certificates of insurance should be mailed to you by the insurance company. A reputable arborist will have liability insurance as well as workers compensation insurance. Many homeowners have had to pay large amounts of money for damages caused by uninsured individuals claiming to be tree experts. You can be held responsible for damages and injuries caused by companies you employ.

Get It In Writing

Most reputable arborists have their clients sign a contract. Be sure to read the contract carefully. Don’t be afraid to ask such questions as: - When will the work be completed? - Who will be responsible for the cleanup? - Is this the total price? - If I would like more work to be done, what is the hourly rate?
