Tree Risk Assessment Services

We offer 3-levels of services to identify and diagnose potential risks, along with a plan to mitigate those risks. With ice storms, Nor'easters and hurricanes increasing in our area, downed trees and limbs causing power-outages and damage to assets are becoming more common. 

This proactive service is designed to protect businesses, homeowners, and municipalities from:

  • Personal injury and liability
  • Property damage
  • Disruption of activities

As well as being a certified arborist, our own Peter Madsen is further qualified by ISA through their Tree Risk Assessment Qualification Program (TRAQ). Peter and our team look for signs such as: 

  • Targets
  • Included bark
  • Co-dominant stems
  • Visible decay, cracks, holes in tree trunks or branches
  • Construction damage--> severed roots, compacted soil
  • Removal of adjacent trees--> loss of wind buffer

Level 1 - Limited Visual Assessment

Level 1 Assessment is performed by walking or driving by a tree and looking for obvious defects, hazards or problems.  


Level 2 - Basic Assessment (most common)

Level 2 Assessment involves a detailed inspection (from the ground) of the site and the tree, including the root zone, the trunk, the scaffold branches and the upper canopy. This assessment also considers potential targets that may be impacted by tree failure and the possible consequences of failure.


Level 3 - Advanced Assessment

The Level 3 Advanced Assessment involves a more thorough examination of specific defects, tree parts or targets. 

Specialized tools are often used in an advanced assessment. Examples, include resistance drilling devices, sonic imaging devices, air tools for excavating roots, etc. The use of these tools requires special training and the ability to interpret the acquired information.

Advanced Assessments are most often performed by arborists (us!) with experience in the use of these specialized tools, as well as an understanding of tree biology and biomechanics.

 

 

Tree resistance testing 

We offer tree resistance testing using our cordless resistograph tool. Using a small drill bit we can drill into a tree and create a profile of the drilling resistance within a tree, which can then be evaluated for cracks, hollow's, and rotten areas. A large, seemingly healthy tree can pose significant risk to a nearby house if it is not structurally sound in it's interior, and this tool allows us to better evaluate that possibility.
