Hello everyone I am new to this so I apologize if I seem a little slow mentally.
I have a 104 yr old home that at one point had a deck that was completely enclosed. my issue is that the floor was built at a slope for run off but was never corrected after the room was built. the floor itself is 3/4 tounge and groove. So here is the other issue. I only have about a 1/4 of an inch to work with at most on top of the sloped subfloor at the threshold. to be honest I believe the finished floor and the sub floor were meant to be the same in this room. I would like some suggestions on how to not only level the floor but also be able to add a finished floor on top of it.
