In an old house you are going to, without a doubt, run into some failing lumber. One of the ceilings was sagging a bit and the valley in the roof is sagging, as well. After speaking with our structural engineer (Daddy Gilliam), we devised a way to clamp off to one of the existing chimneys to help support the load. As you can see, we created a giant clamp from 2x12's and tied it off to all of the ceiling joists that were sagging. Thanks to some help from my brother-in-laws Thad & Bradford we made quick work of it.
