I would like a new door home. To all rooms (4). How do I do it when I want wooden doors and wooden furs? I have a classic prefabricated iron fur. Will the iron ones have to be demolished and the wooden furs taken there? Or are they making some wooden furs that I put on the existing ones and it will be without cutting? If only it would hold the door. I'm sorry, but I'm a woman, so I'd rather ask.
