It seems it is hard to get a good job done so I am attemptingto undo a wall with 2x4's. The contractor glued wall covering
to this wall and it started to remove itself. Therefore, I tore it
all off. Wow, what a job.

Now the wallboard is off and the old insulation is out. I have
r13 to replace it (per lowe's).

The question (after all that) is when the wallboard is attached to the studs, can the wallboard touch the foundation or must it
be above the foundation?.

Anything else you know will be appreciated.

I hope you understand this. I'm just learning.

 

If you mean can it touch the floor, yes. Usually, it is pushed up against the ceiling and installed. The baseboard serves to cover the gap at the floor. The tight joint at the ceiling is easier to mud and tape.

 

Thank you Chfite. We'll be doing this today.
