Repairing/Matching Hardwood floors
My fiance and I recently purchased our first home together (a cute little ranch) and decided to rip up the old, badly stained, carpets. The original hardwood floors were looking good until we got to the dining room. Unfortunately the previous owners cut a nice chunk out of the corner of the room (about 4' x 1' area). My research has only confused me more...some saying that it is impossible to repair old floors while others promise good results if we feather in old/new planks with some sanding, patience & elbow grease. The floor is full red oak hardwood, 2 1/4" wide, and 3/4" thick. We can see that the planks have slanted nails going through every few inches so I am not sure we can pull up the boards without damaging them. Our second dilemma is whether or not we will open the kitchen up to the dining room space. Would having two different types of floors be an issue? Would saving the current floor be feasible or worth it if we try opening up our space in the future?
Any help would be greatly appreciated!! Thank you!!
