Why Hire a Certified Arborist?

Tree CareBy Richard Kemayou15 July 2026

A certified arborist has proven their knowledge of trees through the International Society of Arboriculture exam. Hiring one means the right diagnosis, the right cuts, and honest advice, not just someone with a chainsaw.

What is an ISA Certified Arborist?

An ISA Certified Arborist is a tree care professional who has passed the International Society of Arboriculture certification exam and keeps that certification current through ongoing education. It is a recognised mark that the person working on your trees genuinely understands them.

Why it matters

So much tree work is judgment rather than muscle. Knowing when a tree can be saved with pruning or cabling instead of removed, spotting disease like Dutch elm or black knot early, and making cuts that heal properly all take training. The wrong call can kill a healthy tree or leave a dangerous one standing.

What you avoid

  • Topping and bad cuts that ruin a tree's health and shape
  • Removals that were never needed
  • Unsafe work that risks your property and the crew
  • Disease spread by pruning at the wrong time

How to check

Ask whether the arborist is ISA certified, and choose a company that stands behind its work. With us, every job is led by a certified arborist, so you get qualified hands and honest advice. Learn more on our certified arborist page.

A certified arborist will often save you money, by keeping a tree you would otherwise have removed, or by getting the job done right the first time.
