I contacted Heartwood in July 2012 after plumbers told me part of my sewer line had to be dug up, endangering my 70-year-old magnolia tree. While other companies I contacted were all for having the tree removed, Heartwood was determined to save it if feasible. Fortunately the sewer issue was resolved in a way that minimized impact on the tree compared to the original assessment, so Heartwood re-evaluated a second time and recommended reducing the crown by 25 and adding a support cable to it. They postponed this work until February when the tree could best withstand it. Was very pleased with the results as well as the extra efforts by Heartwood's Craig and Simon (multiple visits while sewer work was underway to gauge firsthand whether keeping the tree would pose a safety issue) and would recommend the company without reservation. These guys love trees!!!
