If I were you, I would buy new interior doors. Why redo the old when you can buy new doors with a modern design and better quality. We change doors about every ten years. The old doors are still in good condition, so sometimes we sell them. Recently we ordered flush doors that fit our interior perfectly. I like this door design because it looks very modern. I am very serious about my home design because it is important to be in a space that I like. I try to create comfort around myself and my family, so I pay attention to the smallest details in the house.
Depends what they are made of? Wood, metal? I just did my metal doors that are interior but lead to outside
Need more information please
