Cracks in joist
One of the 2x10 joists in my basements has cracks in it. Each crack is roughly 3-4' in length but only appears on one side of the joist. The other side of the joist is smooth. The side with the cracks has a heat duct running parallel to it. There are no holes or notches in the joist. No other joist in the basement has any cracks. Joist is level with no sagging. Should I get out in front of this potential problem and sister the joist with some 2x10's? Would I have to use a joist the same size as the original joist? I am concerned that it might be tough to get a full size joist in place with the existing utility lines and framing. I have access to the joist from both an unfinished part of the basement as well as a finished part with a drop ceiling.
