There were several areas to which I was not granted access to inventory Heritage trees (see map for outlined areas). Gianelli Co. are tree specialists who use their education, knowledge, training and experience to examine trees, recommend measures to enhance the beauty and health of the trees and attempt to reduce the risk of living near trees. Gianelli Co. cannot detect every condition that could possibly lead to the structural failure of a tree. Since trees are living organisms, conditions are often hidden within the tree and below ground. Gianelli Co. cannot guarantee that a tree will be healthy and/or safe under all circumstances or for a specific period of time. JBG; bg Enclosure
