Seattle Tree Preservation Inc.
Consulting Division


 


This company no longer has a Consulting Arborist division. However, we can provide referrals to other Consulting Arborists in the area. We do still offer brief informal consultations for a $50 fee. This includes a face-to-face meeting with one of our ISA Certified Arborists who will provide you with information regarding the health of your trees & shrubs. We dont offer soil analysis, root disease diagnosis, or decay detection. We will make recommendations based on the visual evidence, and years of experience dealing with commmon tree problems. Should you proceed with our recommendations within 90 days, the $50 fee becomes a deposit toward the total cost of doing the work(whether it be pruning or removal).

Among the services a Consultant provides are... 

Tree and Vegetation Management Plans:

Consultants provide management planning for any size property including: small homes, estates, condominiums and corporate campuses.  A well thought out management plan corrects problems over time and saves money.

Tree Disease Diagnosis:

 We are familiar with the typical tree disease problems in the Northwest environment.

Tree Risk Assessment:

When clients are concerned about the health and safety of their trees, consultants use a science-based approach to evaluate the structural condition of the tree.  In our experience many trees that have a high-risk potential can be recognized as dangerous and managed for hazard mitigation or removed.

We recommend arborists who use the International Society of Arboriculture Tree Hazard Evaluation Form as a tool in assessing risk.

We can also provide referrals of consulting arborists who use the latest tools and instruments such as the Resistograph Drill and Air Spade to aid in evaluation of tree structure and stability.

Appraisal of tree damages or loss:

We can refer Consultants who are experienced in the accepted methods and procedures used to appraise the dollar value of trees and shrubs.

Storm Damage:

Storms may cause limbs to break or entire trees to fail, often falling on houses, cars, utility lines, other structures.  Be proactive! Do what you can to prevent these hazardous situations from occurring.  Have your trees inspected and cared for by ISA certified tree experts, before disaster strikes.
