Tree Roots
Our certified arborists investigate tree root damage cases using forensic methods to determine causation and liability. We assess root cutting impacts, soil compaction effects, and structural damage to provide expert testimony in construction defect and property damage cases. Our analysis follows industry standards while considering environmental factors affecting root health.
Tree Appraisals
We conduct precise tree valuations using trunk formula, cost-to-cure, and replacement methods for legal proceedings. Our appraisals consider species, condition, and location factors to determine fair compensation in trespass, eminent domain, and wildfire cases. With 3,000+ completed assessments, we provide defensible valuations accepted in courtrooms across California.
Property Damage
Our team evaluates tree-related property damage claims through detailed forensic investigations. We analyze structural impacts from root intrusion, canopy failure, and construction defects to establish liability. Our reports include remediation cost estimates and compliance assessments with California's tree protection ordinances for premises liability cases.
