Choosing an Arborist

Why hire an arborist?

The simple answer to this question is that most arborists are more knowledgeable about trees, tree biology, and tree care than the average property owner. An arborist by definition is “an individual who is trained in the art and science of planting, caring for, and maintaining individual trees.” Much of the training is acquired through education and certification but a lot of it comes from years of professional experience.

Here’s a few things to consider when choosing which Arborist to hire:

Responsible practices

Reputable arborists will only perform industry-accepted practices (AS 4373). Unacceptable practices include tree topping, using climbing spikes on trees that are not being removed and removing or pruning trees without a good reason.


When checking the yellow pages, internet or your local phone directory look for arborists who list themselves as Certified or display the official logos of their professional memberships


Ask if the arborists on staff are certified and what certification they hold. Certification is usually good demonstration of professional capability.

Professional affiliation

Ask about membership with professional organisations such ISAAC (International society of Arboriculture, Australian Chapter) Affiliation with industry organizations demonstrates a willingness to keep current on the latest techniques and information.


Ask for references from past customers and do not hesitate to check them, or to visit the locations where the company or individual has done tree care work.


Do not be afraid to ask for an estimate, and it’s best to get more than one estimate. Keep in mind, selecting the lowest bid is not the best way to select a tree care company. Rather, when examining the bids, look at all specifications and credentials, and the work to be done to determine which company will provide the best service. And, most importantly get it in writing.


Ask for proof of insurance and then verify coverage with the insurance company. A reputable company should have public liability and employers liability to cover personal and property damage as well as worker injury. If you hire an uninsured tree worker, you may be held liable for any damages or injuries that occur while they are on the job.

Remember at first glance a well pruned tree often looks as if no work was done at all.
