When Should You Consult an ISA Certified Arborist?

While any trained technician can grind an isolated stump, you need an ISA Certified Arborist when evaluating living tree health, root damage, or legal boundary disputes.

Contractor vs. ISA Certified Arborist

A stump grinding technician operates specialized machinery to eliminate dead wood. An ISA (International Society of Arboriculture) Certified Arborist is a trained plant healthcare professional who understands tree anatomy, vascular flow, root biomechanics, pathology, and structural risk.

Signs You Need an Arborist Consultation

Consult an arborist if you are considering removing large surface roots from a still-living tree, suspect an invasive pest like Emerald Ash Borer or Oak Wilt, need a municipal tree permit application, or have co-owned boundary trees with a neighbor.

Root Pruning Without Destabilizing Your Tree

Never let an inexperienced contractor blindly chop large anchoring roots near a mature tree. Cutting roots larger than 2 inches in diameter can cause irreversible fungal infection or cause the tree to blow over in high winds.

Frequently Asked Questions

Q:How do I check if an arborist is currently certified?

You can verify any arborist's credentials on the official International Society of Arboriculture portal at treesaregood.org using their name or certification ID number.

Safety Reminder: Locate Underground Utilities First

Before any stump grinding machine cuts into the ground, contact your regional call-before-you-dig service (dial 811 in the United States or visit clickbeforeyoudig.com in Canada). Always inform your operator of private lines such as sprinkler lines, septic tanks, or low-voltage lighting that public utilities do not mark.
