I have a customer that has a old chain link fence and his neighbors over the years put up a nice pvc fence around his property. so he wants me to take the old chain link fence down. it would be difficult to dig out post because its very close to the pvc fence. customer is ok with me just cutting post down as long as he doesn't see it. is it possible to use a replicating saw and just cut post down to the ground?? i never down this before so any help would be appreciated.
