How to stabilize stairs

Hi everyone, looking for some suggestions on how to firm up these stairs. Trying to be proactive here before someone gets hurt. Below you’ll see a picture of the stairs that lead down to the basement. I “think” they’re just nailed to the wall at the top. The steps (treads?) themselves seem to be partially “in” the stringer.

I think there are two problems. (1) One problem is that it’s as if someone is taking the stringers and pulling them apart. So the treads are falling out like in the picture. We tried putting in some cleats temporarily but it’s not great. (2) Second problem is I think the top of the stronger needs to be attached in a better manner than nails. Isn’t there a specific metal bracket sold for this?

thanks!

I would start from the beginning and remake the steps up to modern code. It's a small stair so the cost would be minimal.

Fixing this stair is pretty straightforward though I wouldn't recommend it. The first step (pun intended) is to simply re-assemble the stair. Repair and reattach the joints that have failed. I'd liberally use a quality wood glue and some screws. The attachment to the house needs to be addressed. Adding a ledger board is one option or you can use steel brackets. Or, you can even add framing to the stairs providing support to the floor almost making the stairs freestanding.

I would remove these and build new stairs. Such a small set of stairs is a half day project with minimal tools. You can buy pre cut stringers and treads. If you add a header at the top and a kick plate at the bottom they will never move.

Thanks for the replies. For attaching it to the house, would you use special screws/bolts made to go into concrete? Or molly bolts for concrete?

I also recommend building new stairs. If you want to do so, there are some good carpenters here who can guide you through the process. Good luck with your project.
