I had called a few tree services for an estimate on removing a tree growing between my house and the neighbours. I only heard back from two of the businesses, one tree service made an appointment a week later to give an estimate. Mapleview came out a few days later, gave a fair price and the tree was removed within a week.
These are skilled pros, the whole process of cutting down a large maple took a little more than 3 hours which also included cleaning up. They were a pleasure to deal with from start to finish.
My advice is to start your shopping with a call to these guys.
