An addition was started on Sept. and finished in January. When the warm weather came there was a noxious odor in a room under the attic where the roof had been extended and above the entranceway where the basement had been extended. I had an environmental company investigate and they concluded that the wood had a tremendous amount of sap and that was causing the smell. A year has passed and as the temperature has begun to warm the odors are back. I spoke with a lumber store who said that even if that the wood should have reached equilibrium by now. Do you have any suggestions?
