Converting stairs

skid78 · 07-21-2009, 08:56 PM

Iam going to be removing the carpet off our staircase and putting down new oak treads. The current stairs are closed in and Iam looking to make the new stairs open. Wondering if I could just remove the old treads and risers, cut the drywall to match the stringer height put down my new treads and risers. Also we have a lainding half way up the staircase, with plywood underneath. Was wondering if I could simply cut the plywood out and install oak boards in place of the plywood. Thanks

There's nothing necessarily "simple" about what you're proposing. If the treads are mortised into the skirt board you've got your work cut out for you. At the landing you need the plywood sheathing on the floor, and the hardwood goes over that. A big challenge with re-facing stairs is keeping the rise and run dimensions consistent without creating variances that make the stairs unsafe. Another big issue with what you propose is squeaking.

As for the drywall, it depends on the wall. Some stair walls are bearing walls and cannot be easily modified. Some are non-bearing and can be shortened, although kneewall stability can often be an issue that takes people by suprise.

I agree, Id tear them out and start from scratch.

What is the code on open stairs now?

Gaps at open risers can't permit passage of a 4" sphere. That what you mean?
