Well, we are hoping so anyway. Guess we will find out in a few months.
This weekend we had a tree cutting party. The neighbor had a tree to cut down and so did we, so we went in on a cherry picker together. Long story short, the tree in the front of our house that had the roots growing into our water pipe is now gone. Left in its place is the stump and all the leaves and small branches waiting to get picked up during branch pick up next week. half the wood is stacked neatly in our backyard to use for firewood next year, and the other half is sitting in the neighbors yard. (we gave them half the wood for doing the hard cutting part in the cherry picker)
So, now we can see into the neighbors front window and they can see into ours. We have also lost a bit of the shade that was provided by that tree. However, it may help heating costs in the winter as the sun can get through now.
And we will have to wait and see to find out if this ends the plumber having to roto-root every few months. If not, we will have to start the search all over again to determine the problem.
