Folks: We found some dry black spots after we removed a portion of a base board and underneath the carpet. The issue was that during rains there was water use to come and kept this area wet. Now I sealed the hold for the water but i now i see mold spots. I cleaned up with a bleach but would like to know if i should replace the floor boards or let it dry and put the carpet back. It is on the second floor near the deck door.
