Why do stairs have stringers?

How to close gaps in stringer?

What can go wrong with stairs?
Many things can go wrong with your stairs. They can squeak or loosen between treads, and stairwells attached on only one side—known as open stairs —can even begin to separate from the wall. To diagnose problems, start with a visual inspection for gaps, and a walking test to feel out any movement (or give) and to identify the location of squeaks. The good news is that most problems are familiar to a competent carpenter. The bad news is that the plaster or paneling (or whatever else covers the underside of the stairs) must be removed in order to reach the problem. Frequently, the 2x4s at the sides that hold up the ceiling (the underneath part of the top stair) must also come off; save them for putting the ceiling back. Once the cover is removed and the stair’s innards are laid bare, repairs won’t seem so daunting. (Repairing the hole you’ve created usually isn’t too difficult, either).
