Hazard Tree Assessment

When a tree shows signs of damage and poses the risk of falling or dropping limbs, you’ll want to take immediate action. Preventive tree care can save thousands of dollars in potential property damage or removal services. Evaluating the seriousness of the tree’s structural weakness is best done by a professional arborist.

At Guardian Tree Systems, our arborists understand tree biology and physiology. They’ll identify any flaws in tree structure such as cavities, decay columns, splits and hazardous limbs.

They’re also well trained in assessing damage caused by storms, a frequent problem here in Ontario, Canada. But storms aren’t the only culprit.

Trees can become a hazard for many reasons including the following:

  • Age
  • Storm/wind damage
  • Lightning
  • Snow or ice
  • Uprooting
  • Disease
  • Nutritional deficiency
  • Insect infestation
  • Structural weakness
  • Soil problems
Seasonal mulch and wood chips available.
