cut down a tree

We were contacted to remove a Manitoba Maple tree (also called box elder) in the South Keys area of Ottawa. When we got there to take a look, we were surprised at just how big this tree was: it spanned over FIVE different houses! At first, the tree looked ok, but after climbing up into it, could see many problems: cavities that had formed in the tree, cracks, fungus, and decay. It needed to be cut down.
