Mismatching subfloor heights for old and new part of house
megs13

I am trying to remove the old carpet and refinish the hardwood floors that are in the original portion of my house built in the 1930s. My issue comes with the layout of my home and the plywood subfloors in an addition from the 1980s. The back wall of the original dining room was opened up and a family room was added. I would like to continue the hardwood flooring into the new portion of the house, but the plywood subfloor is higher than the subfloor of the original house. There is only a 1/4" gap between the heights of the plywood subfloor and the hardwood floors, the hardwood being the higher of the two. The hardwood in the house is 3/4" thick. Anyone have any ideas of how I can get the hardwood floors to match? Would it be a difficult fix to change the subfloor? I'm assuming the difference has to do with the difference in the foundations. The older portion is over basement and the newer portion is over crawl space. I'm also considering doing tile in the family room which would be a more straight forward approach and can easily be done in this case, but I wanted to see if hardwood would be feasible first.

Given your numbers, you can't do it.

If you use similar hardwood in the family room, the floor will be 1/2" higher than the original portion.

However, if you use tile (and you have to verify that you can do it), then you will have both floors on the same level.

Since you already had a change of materials, would it be terrible to use a wood transition to make up the difference between the floors?
Using a thinner laminate flooring might work, but the appearance might not match or be what you want.
