During a big wind-storm, we heard a loud crack in our backyard and saw that one of the main forks of the trunk had completely cracked and was hanging over our roof. We called Oxford Tree Service the next day and they checked the tree out and showed that the entire core was rotted out - unfortunately, our tree had to be taken down. We have a small yard with fencing all around and they managed to get the machinery into the back yard and take the tree down. The work was done within one week, and the stump ground down the following week. We requested that some wood be left for us for our fireplace, and the rest was removed by them.
