I live in a 38 year old split level home and I have 5 wooden steps that are cracked and they creek when you step on them. I thought they would need to be replaced but a floor company told me about a system called "NuStair, stair refacing system". He said it fits right over your old stairs. Has anyone heard of this?

Yes but they must screw and glue the creeky stairs before they start. Stair False Tread Kits l Oak Stair Parts l Stair False Tread End Caps - <span>Treads</span> Risers & Trims

Thank you so much. I will make sure they do that.
