Unfortunately, when Maples get this old, they start to deteriorate very quickly. It appears from the photo that this tree is dangerously close to your house. This will cause many problems if not resolved quickly. Their roots are also highly invasive, so if you have a septic tank nearby then I would also have that inspected. It is recommended to plant large maples at least 20 to 50 feet from anything that could be damaged by invasive roots.
