Services
All inspections and assessments include the preparation of an arborist report.
Tree Diagnosis
We use a variety of diagnostic techniques to identify the root cause behind a decline in health, whether the culprit is pests, parasites, diseases, or environmental factors, and provide recommendations for treatment or management.
Risk Assessment
All trees pose risk – you should be informed about the level of risk your trees may pose, and how to mitigate that risk. We are certified in tree-risk assessment and provide assessments and recommendations.
Real Estate
We are experienced in conducting pre-sale inspections for buyers and sellers.
Pre-sale inspections can identify hazard trees for seller before listing to expedite a sale, or identify hazard trees for the buyer to identify liabilities and enable estimating costs for repair.
Appraisals
Trees can add great value to a property - we can prepare tree appraisals in accordance with the Guide for Plant Appraisal (10th edition, 2019), authored by the Council of Tree & Landscape Appraisers (CTLA).
Inventories and Mapping
Do you own or manage a lot of trees? We conduct tree inventories and prepare maps for a variety of clients, including homeowner's associations, commercial properties, parks, and schools.
Tree Protection Plans
Planning a construction project, major remodel, or garden redesign around existing trees? Does your city require a tree-protection plan as part of the building permit process? Let us help you preserve the health of your trees and navigate the permit process.
