How to repair subfloor rot
Hello,
My hardwood floor have sustained some water damage this year, now that its all dried up it looks like the subfloor is rotting - please refer to the picture. The rot hasnt spread very far as of yet.
Can anyone tell if this is wet or dry rot?
What is my best course of action here? I want to salvage this subfloor.
Thank you very much!

Poke it with a screwdriver... if it's still fairly solid, it's no big deal. If it's a little soft in a small area directly above the joist, you could sister a couple short pieces of wood to each side of the joist to add support where the plywood is more solid. No big deal.
Things rot because they are or were wet, not because they are dry so there is really no such thing as dry rot.
The discoloration is just a stain.
Only way to replace it is to tear up your hardwood floor... even if there is a few inches of rot, i doubt it is worth all that.

There is no visible staining on your floor joists. I would just monitor and move on to the next project. I've seen far worse and yours looks to be very minor.

I have to totally disagree, there's a reason that the sub floor is stained like that.
It most likely was caused from something outside that's going on.
Post some pictures of the outside in that area.
A deck attached to the side of the house with improper flashing, siding to close to grade, no gutters Ect.

Yes, this looks like water seeped through the joint where two subfloor panels met and did some wicking into the plywood. It will dry out in time and the stain is not structural. Lack of any staining on the joist says it was a one time event and there is nothing to worry bout.

yes, it was a problem outside that was causing the issue but it was resolved. There is a door to the outside right above this that had a sill that was leaking. but we solved that issue. Thanks again!
