If you’re budgeting a basement staircase remodel in St. Louis, most projects run $2,019-$9,086, 1% above the $4,500 national average. What moves that number most is usually one thing: Number of Steps. On its own it can swing the cost by $100 - $600 per step, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Overlay new treads on existing stringers instead of full replacement. If your stringers are solid, you can install new hardwood treads directly over the existing structure at a fraction of full replacement cost.
