Hi! I recently noticed a horizontal beam in our kitchen has horizontal cracks along the entire side, which I’ve read in the forums here could be “checking”, but the beam is also slightly bulging where those cracks are happening and the beam appears to be twisting. You can see in the photos that there’s a gap where the beam meets a vertical post it’s resting on.
The house was built in 1965 and I’m not seeing any of these issues in any of the other beams. Should I be concerned? Thanks for your help!
