Converting from carpeted stairs to Oak

Katumbo

I am in the process of changing my carpeted stairs to Oak stairs,
I need some help to maintain the Canadian code for stairs.
1) Currently the existing tread is 9 1/8" X 40" and I need to install oak treads which are 10.5"x40" X1 1/16"
2) My risers are 0.5" thick
3) I have to maintain the nosing overhang of 3/4" to 1 1/2" and the tread run of minimum 9"( measured from nose to lower step nose). I need to maintain a uniform look

My Question is how to maintain all codes I am finding it a bit difficult to figure out is there anyone who can help me with some tips,I would really appreciate the help.Thanks

What type stairs do you have, full mortise stringers or open stringers? Is there an open side or are your stairs wall to wall. What is the reason you can't just remove the existing treads, size the new ones and replace?

Hi Jim
My stringers are open one side, I was told by the guy who sold me the stairs to leave the old treads on and attach new oak treads. Should I remove the old treads?

If your stairs are totally in code now, adding new treads on top of the existing ones would more than likely make your stairs out of code and unsafe, depending on the thickness of the new treads.

To install tread caps on your treads is quite a bit of work as the old nosing has to be removed if I am not mistaken.

Removing the old treads and installing new ones is still quite a bit of work but you can do it. What ever you decide we will try to help you.

Those winders will not pass code btw. The guy who sold you the materials gave you the wrong information. Doing so will screw up your first and last rises. If your all your risers are equal now, then what I would do is make the top of the new treads the same height as what is there now. So you need to rip up those 2x10s and shim the top of the stringers 7/16" to make the new treads the same height as what is there now. You will have problems with those winders though because there is only 3/4 plywood on there.

What we need from you is a rise on each step from platform up. They should be the same. You are allowed to change rise at a landing like that so the rise of the upper stair and lower stair can vary.

No idea what the code is in Canada, but here the narrowest part of a winder tread has to be a minimum of 6" wide.

If you don't change the structure then you are grandfathered in. Remove old sub treads and buy or make treads to meet conditions.

These are Canadian codes
