Mold on floor boards
I had a hard time bringing myself to use the "M" word but I'm really interested in comments from this forum. We used OSB for our floor decking. We were delayed in getting our roof on due to weather etc. I recently noticed what appears to be a mold on the bottom side of the boards throughout the house that you can see from the basement. There is a lot of it. It doesn't have any texture but appears more as a discoloration. I have contacted the lumber yard where we bought the OSB and they were going to go look at it today. Tomorrow I plan to call a home inspector to come and take a look and hopefully give me some good advice on how to proceed. Has anyone on this forum ever heard of this or seen it before. I guess I could see it in areas that were wetter than others but it is pretty uniform throughout.
Thanks for any feedback.
