Ok need some help here... Hopefully the pictures and my feeble attempt to work with MS Paint can explain what I'm talking about.

1) I need to square a step so that it looks square and matches the line of the hardwood I've already installed. How would I do that. I was thinking I would cut strips of wood in declining sizes and nail onto the riser portion so that I can then install a thin piece of plywood over that that would act as the new square riser? Or is there some other method I should employ?

2) How do I cut or adjust the strings on the stairs so that the bullnose can run all the way to the wall on the right of the stair and the edge of the string on the other end of the stairs?

Thanks very much... Tony

Considering the floor is already laid you could shim the riser(you got it with #1) so it will come out square with the floor. Shimming would be done by ripping strips of wood on a table saw then nailing and gluing to the existing riser. Then covered by a permant riser material.

Are the stairs itself out of square or the upstairs? I think you did great with the MS paint!

PS. Next time square the floor with the bull nose first.

Ken It looks like the landing is out of whack. I thought the illegals here couldn't read a tape measure!! That is bad, and surprised it got by during the building, unless it was a spec, built and sold "as is".

If they would have squared off the existing nose, the whole installation would have been out of square with the walls, everywhere.

The floor is square to the walls which where pretty much dead on. It's only this top step that is out of whack.

Oh and thanks for the advice I will proceed with the shimming. the rest of the stairs are square so I'll start from the bottom up...

True, but by only looking at pics, I'm thinking it could have been tweaked somehow, but it does look too severe.
