This is the old floor. Some parts of it had yellow stains on it. It was at least 20 years old (our house is 30 years old & we found an even older floor underneath it. So it wasn't the original floor).
This is the new floor below. I need to take some more/better pictures of it. Maybe I'll do an update post on here. My hubby did it himself, he had some help, but he didn't hire someone to do it. It saved us a lot of $.
