I tried to post this in another thread but it was too old and I have to create a new thread. Lol, so remember to always copy your post BEFORE you hit enter.
The thread I was replying to was here: How I reinforced floor from above
I've noticed a couple of areas on my floor where the linoleum has taken on a grey tinge. One area is a line going across my trailer hallway. It looks like a joint of the plywood underneath and it has now become soft when walking on it.
My concern is that black mold is starting to come through the floor from a slow leak over the years but it just may be the nature of the linoleum.
The other area in under a window in about the same area. It's not a walkable area.
The thread I posted above has really helped in solving how to replace the wood underneath without having to lift up all the affixed furniture. The areas under the seating looks good anyways. As far as the linoleum goes, I'm probably just going to replace it with some new tiles so I won't have to worry too much about using the floor pattern for that part.
I'll document the work too for anyone else contemplating replacing parts of the floor.
