How to fix a crack in a stair stringer?

Hold the board up to the string er, from underneath, and clamp in place until dry to further reinforce the mended stringer.

How many pilot holes do you need for a split stringer?
Drill four to six pilot holes, slightly smaller in diameter than the mending plate or angle iron's bolts or screws, in position as indicated.

Why do stairs have stringers?
This doesn’t happen very often on closed stairwells (stairs with walls on both sides), but open stairwells can experience stringer spread for a number of reasons: House settling, wall movement, inappropriate repairs, and poor original workmanship are all common culprits. The trick is to pull the stringers back together and keep them that way.
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).

The jack can now be let down slo…
