Our house is 15 years old and has not enough space was left above the drywall to allow for settling. Can the drywall walls be cut to allow for the floor to settle? Can you expect the bowed section to settle and the period of time it takes to settle.
All of the settling takes place the first 3-5 years and should have been address then. I’m not sure anything will move at this point.You could have a structural engineer come in and give his opinion.
