Drywall to Floor?
1 Attachment(s)
We have a 3/4" subfloor. Our handyman put the drywall clear to the floor. I've read you're not supposed to have it touch the floor because water may seep up the drywall.
We're going to have the floor tiled. (thinset, Durock screwed in, thinset, then tile).

Do we need to redo this drywall and make it higher and if it needs to be higher does it go above the finished tile or can we just leave it be?

It needs to be 1/2" up of the subfloor.

yup so it doesn`t absorb water off the floor. if its hardwood i keep it up 3/4 so the flooring can be cut closer to the wall and still have expansion space

Call your "handyman" back to do the job right.

No need to remove it if you have an ossilating saw. Just lay a piece of 1/2 anything, plywood OSB to use as a guide and cut it out.

Floor is going to be tiled.
So we have to:
1) remove drywall
2) figure out height above tile so that it's 1/2 above tile?
Is this correct?

We actually used 2 sheets of drywall here for soundproofing.

Can we leave drywall and trim it on the bottom or will that get messy?

Oh, I see Joecaptain just answered one of my questions about cutting it at the bottom instead of removing it.

cantonstf 11-28-2012 04:56 PM

ALright folks..I'm a total newbie... but it's sinking in.

SO it would be the drywall can be cut 1/2" above SUBFLOOR. (not finished tile)?

Correct. If I was looking for sound proofing I would have insulated the wall and used one layer of 5/8 sheetrock. Oh well what you have will work ok.
Not leaving that gap at the bottom is sheetrocking 101. May want to keep a close eye on that handyman.

I hope he will add more fasteners in the field;

1/4" minumum above subfloor, per code;note chapter 4, esp.;


cantonstf 11-28-2012 06:13 PM

I was thinking back on what our handyman said... he said he usually does the floor first then everything sits on that. That would account for the 1/2" gap off the subfloor for the drywall.
I read that you should do the floors last, so that's what I told him, but he kept his same method of putting everything to the floor.

The learning curve is painful.
And thanks, joecaptain, for the soundproofing tip... next time.

I'll tell him to put more fasteners in the field too.

if you dont have a oscilating tool use a recip saw and a 1/2" spacer block to act as a gauge for where to run the blade along

My cutting skills aren't so good and in one area I ended up with a 1" cut above the subfloor. I hope that's okay???
