Property Damage from Neighbors Contractor

[Chris Svendsen]

I have a property located in Altoona PA where we just finished interior renovations getting unit ready to go on market.  I am out of state investor so not at home all the time.  One morning got a call from a contractor letting me know they are replacing sewer line for a home behind our house and that they have to run line through our side yard.  They stated they will be making a small trench but when done will be restoring everything back.  2 weeks later the side yard is a disaster.  Our contractor went over to check on progress for us and find a entire side yard dug up, fence ripped out, trees removed and debris everywhere. Plus the sidewalk was dug up and broken apart.  

3 days later they were done and gone.  Yard was somewhat leveled back out, some seed and straw put down, chunks of sidewalk placed back and that appears to be all they are doing.  Fence is gone, trees are gone, and yard is unusable. I am in town now to visit family and be checking it out myself tomorrow.  Once see in person going to get in touch with the contractor about getting this repaired property however I wanted to see where my legal rights are as I expect this work to be done with no expense to me.

One of reason the side yard was so important is we allow tenants to have animals and for an in city rental it was popular to have the yard for animals and kids to play in.  In process of working to rent unit out now I have had multiple people say how they were looking forward to having a yard but are concerned because it is nothing like in the photos.  In my view proper restoration would be the yard should be returned to state of previously.  Since all grass was removed I expect sod to be placed after all debris is removed and top soil applied, trees replanted, fence installed, and sidewalk redone.  If contractor refuses I imagine I will need to speak with the owner of the property to get them to cover proper repairs.  Do I have legal rights to expect my property to be restored to state before work was conducted?  I feel like I am going to end up having to go to court over this and want to get my ducks lined up.  If contractor refuses to repair I figured my next step is I will get an estimate from contractors to do proper repairs and send this information along with before and after photos of property and a letter explaining the situation to the current owner requesting for them to contact me by a certain date to get the repairs done.  Will send this as a certified letter.  If this goes nowhere will then have a lawyer get to work on it but rather not pay that expense if don't have to.  

Any advice can give be very helpful. Never had to deal with anything like this before so want to make sure I am in the right before moving forward.  Altoona PA seems to run by its own set of rules at time so not sure how this will all work out. Thanks everyone for any help you can give.
