Subfloor question

2 years ago

We noticed water damage on the hardwood floor in our powder room and realized the toilet was leaking. After ripping up the damaged hardwood, this is what the subfloor looks like. is this mold, or just what the subfloor should look like? do we need to replace?

thanks for any help.

If it’s soft you need to replace. If it’s mold (very likely) let it dry then spray it with concrobium which will prevent mold regrowing.

And this is why we don't usually see hardwood in bathrooms.

The wax ring seal for a toilet doesn't last indefinitely. It would be prudent to replace all wax ring seals every 10 years. Otherwise you see this again and again.
