If you want to find out what the contractor didn’t finish, you should definitely have a one year warranty home inspection done.
With our home inspection report you will be able to go to the contractor and ask for the items to be repaired while the home is still under warranty. If you pass the time, and don’t have an inspection performed, you may have to live with the problems and face them when you want to sell the house when a buyer comes along and has a home inspection!
