“I called Dermot Casey Tree Care after an extensive google search and with an appointment made, they sent someone out to check over the trees I have. They identified some that were in danger of falling and treated a couple that had suffered from Dieback Disease. Now with confirmed yearly inspections I am confident in the knowledge that my trees are in good health and are in less risk of falling.”
