Why hiring a certified arborist matters and how do you know if they are certified?

Certified arborists have met various criteria, can demonstrate standardized skills, and have passed a standardized test as set forth by The International Society of Arboriculture. Unfortunately, the tree service industry is very unregulated. Reputable companies participate in self-regulation through participation in ISA. Hiring a certified arborist helps ensure that your trees receive proper care, which is essential for their health, longevity, and the safety of your property.

But how do you know if you are hiring a certified arborist? If someone works in the tree industry, they are technically an “arborist”; however, that does not mean they are a certified arborist. A certified arborist has been assigned a PIN number by The International Society of Arboriculture and everyone has access to research an individual’s credentials. To ensure you are hiring an ISA Certified Arborist, follow this link to confirm an International Society Arborist PIN number.

Certified arborists know how to prune trees properly to promote healthy growth and strong structures. Proper pruning should be done to the standard ANSI A300 pruning method. If a tree requires removal, certified arborists can do it safely and efficiently, minimizing potential damage to property.

Certified arborists are also familiar with local tree regulations and can help you navigate the legal aspects of tree care such as permits for city trees or trees on historical property. A company must be licensed with The City of Boise to prune or remove city or historical trees. Visit the city page of licensed tree services.

Every estimate is emailed the same day as the evaluation with a thorough summary of on-site findings and cost of service.


While hiring a certified arborist is important, there are other factors to consider. Always confirm that the company your hire is fully insured. A reputable company should always be willing to provide a copy of their certificate of liability. This is a document provided by an insurance company to confirm that a business has liability insurance coverage. This certificate outlines the type and amount of insurance coverage, the policy number, the policy period, and the name. It provides assurance that the business is insured against potential liabilities, such as accidents, injuries, or property damage that may occur during the course of work. It serves to protect both parties involved in the business transaction.


After a homeowner or business has done their homework, it is still important to make sure you understand the scope of work to be performed. Timberline Tree Service provides a detailed scope of work which includes pictures and videos in addition to extensive detail so both parties are clear of the work that is to be performed. We have a skilled team and the right equipment to do every job properly, safely, and efficiently.
