I am very new to home repair, and wanted to get some help from a few experts. I am changing out the tile in my entry. It's on a concrete slab, so no sub floor to worry about. What are tye steps to doing this project? Additionally, it feeds into hardwood floors. Do I pull up the lip covering the change from tile to hardwood, and replace it with a new one? Or can I save it and use it again? Thanks for your help.
