To start, apologies if this is a redundant post. But, I haven't found a lot of success with my specific situation. Our home is a rancher with a basement. We have started removing some drywall and studs for a basement remodel we are doing. We noticed that the ceiling was sagging before we removed the existing 2x4's. They did not appear to be load bearing. Ideally, I would like to fix the slight sag, about 1/4" spanning approx 5' 10", in the basement ceiling/upstairs floor. Our plan was to add 2x6s to the existing span and jack them up into place, get them level and it would fix the sag. The pictures are of the span with the sag. The research I have done appears that you will need to fix this with small adjustments over time. I'm hoping someone here has the expertise to help us so we can get this done and then move forward with our project. Pic 1 - With the drywall removed Pic 2 - Studs removed Thanks in advance.
