Tree Risk assessments by Treemasters in San Rafael and the Bay Area

Have you noticed any sudden changes to the trees in your care? If you’re concerned about identifying potential hazards on your property, investing in a tree risk assessment is a wise choice. Our team of experienced arborists has over 70 years of combined experience serving the community of Marin County. We can offer you advice or recommendations on how to maintain the strength and health of your trees, ensuring they’re primed for any weather. 
Delaying professional help could result in the tree’s health deteriorating beyond redemption, or it becoming a safety risk to nearby structures, utility lines, or people. If you suspect that a tree on your property may be a risk, don’t hesitate to call the experts at Treemasters immediately.

How Do You Know If Your Tree Is High Risk?

While there are many signs that a tree may be at risk of becoming or is already a hazardous liability, some signs are more easily recognized than others. 

If you notice any of these indicators of a high-risk tree, request a tree inspection ASAP:

  • Large cracks or hallows in the trunk
  • Wilting or failure to bloom
  • Hanging or broken limbs
  • New or worsening lean
  • Signs of insect damage or disease

What to Expect from a Tree Inspection

Tree inspections must be requested by customers and will be billed for the inspection.

So you’ve identified a risk and called in the experts. What happens next? After scheduling a tree risk assessment, a skilled arborist will meticulously examine your tree and its environment to pinpoint any vulnerabilities or prospective concerns.

There are three levels of tree risk assessment:

  • Level 1 Visual Tree Risk Assessment – A limited inspection that’s conducted when there’s no reason for elevated concern about a tree’s health. Our tree experts can ascertain much information about a tree even from this level of inspection, but there are limitations to the risks they may detect. A Level 1 Tree Risk Assessment may involve walkarounds and photographs.
  • Level 2 Moderate Tree Risk Assessment – A more thorough tree risk assessment that pays special attention to a tree’s roots, trunk, and crown. It is a 360-degree, ground-based visual observation of the tree. If any structural defects are found, your tree expert will recommend your best options moving forward.
  • Level 3 Comprehensive Tree Risk Assessment – The most detailed level of tree risk assessment includes a thorough review of the tree’s root system, trunk, and crown. In addition, a certified arborist may conduct tissue testing and resistance drilling on your tree. Level 3 Tree Risk Assessments include ground-level inspections and may also include drone or crane inspections.

How Does a Tree Risk Assessment Work?

One of our arborists will inspect the trees on your property and assist you in determining the best course of action. With decades of tree care experience between them, our arborists understand the unique requirements of trees in Northern California and the many conditions that may affect the trees on your property. 

Each tree is individual in its needs and may require its own unique treatment plan. In order to best care for your property, we evaluate trees for the following:

  • Pruning and Removal Needs
  • Cabling and Bracing
  • Soil and Root Analysis 
  • Soil Nutrient Management
  • Pest and Disease Control

Your Arborist will walk the property with you to discuss the needs of your trees and how to keep them healthy, strong, and beautiful. With the information gathered, they will provide you with a detailed written evaluation for the for the recommended tree care, along with digital photographs of the tree(s) being examined. 

We even offer resistograph services to inspect for internal pockets of rot or decay, for a more in-depth assessment of your tree’s stability.
