Dead tree removal and replacement
We are not aware of anyone who performs tree removal services free of charge.
We can't recommend particular arborists for tree removal, but following is a web site listing of certified arborists in the area. You may want to get prices from several of them. This is a good time of year to have the tree removed before they become very busy in the spring. http://www.treesaregood.org/findanarborist/arboristsearch.aspx When you call it would be helpful to them to know the approximate height of the tree, location (front, back yard, etc.), and how accessible it is.
Go to treephilly.org to look into getting a free tree to replace the one you are removing.
Hope this information helps and good luck with your tree.
