In order to determine a tree’s health and stability, our experts may require information that cannot be seen from the exterior, such as problems within the core of the tree. An analysis using a resistograph can help accurately diagnose the situation.

A resistograph is an instrument that uses a very thin stainless steel drill bit to measure the resistance of wood. The rotation speed of the drill varies with the state of the wood, and this very precise data and can be analyzed by an arborist to detect wood decay, stages of rot, hollow areas, cracks and ring structure.

Trees are able to heal the thin hole left by a resistograph without long-term damage.

We also offer our resistograph services and analysis to inspect the integrity of wooden utility poles, which can degrade over time.

Having the most accurate insight into the health of trees and wood is key in evaluating the safety precautions that should be implemented and determine the best course of action for the trees, property and people.

Our certified arborists have the knowledge and experience to correctly apply resistograph equipment, analyze the results, and respond appropriately.

We are happy to advise you on the health of your trees, whether a resistograph is necessary, and what steps to take next.
