Minor floor repair

[mfdengineer]

I finally got around to removing the jack knife bed and carpet to replace with tile. Unfortunately I found some not so pretty plywood underneath. I want to replace the rotten plywood but I'm not sure on how to do it right. I peeled back some of the old tile that butted up against the carpet and I cannot find a joint. Is it sufficient to just cut a square section out to remove the rotted part and replace or do I need to cut a section from wall to wall and replace for stability?

Looks like you did a nice job.

I got the new padding and carpet put in finally. I had to put new insulation in the boxed frame behind the couch and get it back together. I got the couch put back in and now I am covering the new plywood top. Man this has been a lot of work.

Check marker lights on the outside top for leaks. They are a common source.
Repair looks good!

After much cleaning and fighting rusted screws I finally got the floor replaced. I only cut out enough to remove the rotten parts but still be stable. I cleaned and painted the rusted parts of the frame and sealed up some gaps with foam sealer. I used some caulk around the seams of the new pieces and then sealed it up with rustoleum undercoating. Turned out pretty good I think. Now I have to build back the box frame that was behind the couch and then get the carpet. Sure has been alot of work but I am happy with it so far.

I apologize for the low quality cell phone pics. I was too tired to get my good camera.

It is definitely going to have to be cut out. I can poke my finger through with little effort. It is all dry right now and we just had two days of rain so that is what makes me believe that it was coming from the roof seam. Just two months ago, I resealed the three seams on the roof with eternabond because the old sealant was looking bad. I have not located anywhere else that it could come from. By looking at the marks on the fiberglass it does look like it ran down from the top. Also, I am considering just going back with carpet.

Git-Rot can be a good alternative to removing rotten wood. It soaks into the wood fibers and the result is stronger than the original wood.

I agree with Gene - let it dry out real good and see how solid it is when it's dry. If it's still solid and just discolored, then I'd coat it with something and then go back together, but do be sure you figure out where the leak is coming from and address that first (if you have not already done so).

If you get into cutting flooring out, you could be opening up a real can of worms and I'd hate to see you do that if it's not absolutely necessary.

Don't be so quick to cut the OSB out.....in order to prep for tile you will need to skin over that floor with something suitable......let it dry out, maybe just epoxy or flash patch over the damaged area, then skin over the entire floor with Hardie, glued and screwed.....
