Debra...Is it already painted..if some sand and repaint.
Deep clean floors and repaint trim and doors.
Hi Debra: You can pull it up and replace it with new. It's not all that expensive and not all that hard to do. Buy more trim than you need so that you can practice mitering the corners:) The trim comes painted or unpainted. Most home improvement stores sell it. Don't be intimidated, you can do this. Good luck
