Thanks for the recommendations on the screens. I now have a new request and hope you can also help again. I believe I am going to need an arborist for the simple reason I have a tree in my backyard that needs to be trimmed back. It is very tall and cannot be done by an extension trimmer. You also cannot climb up in the tree and cut pieces down because the limbs would not be sturdy enough for someone to sit on. It is a cherry tree of some type. It needs to be trimmed down in about half its size right now. Unfortunately the former owners never kept the tree trimmed and its out-of-control. Your suggestions are welcomed and I appreciate it in advance.
