Hi, I have some squeaky stairs going from 1st to 2nd
floor. Below them is the staircase to the basement, but
the stringer are covered by drywall. I have some
drywall work I need done and my question is, should I
take down the ceiling drywall, fix the main stairs from
underneath, and then have the contractor patch it up?
or just fix the squeaks from above? Thank!
