Can We Talk Drywall Cracks?


First off, I am not a framing and drywall sub/company. Just a GC trying to avoid these costly and annoying issues. Despite understanding how many of these occur, there is always the big crack along a board edge in the middle of the family room or kitchen where the homeowners flips out.

Theres always the occasional screw pop or crack along board edges. And depending on the situation, we can typically just re secure the board edge with new screws, OR completely open up the area(if board edge is just hanging free), add some plywood backing and cut a new piece of board, tape,skim, repaint(hopefully not entire room).

So Id like to really discuss-

1)What do you guys find as the most common culprit, and what can we do before they happen.


2) What is the best route to take to fix a crack along a board edge?

Interior or exterior wall? Floor above or roof? Vertical or horizontal seem? What do you mean edge of board is just hanging there? The vertical edge of the sheet needs to land on stud or butt board, shouldn't be hanging there. Possibly framing drying and/or house settling as weight in material is added.

Re: Can We Talk Drywall Cracks?


As a painter doing repaints in 5 -10 year old houses, I am questioning the amount of mud being used finishing drywall, especially in corners. I think if you add in the overuse of lightweight and ultra lightweight mud, could this be a factor too?

My engineer says these cracks come from not having sufficient king/jack stud combo.

Re: Can We Talk Drywall Cracks?


Typically my projects are single floor residential and cracks have typically occurred in ceilings. We use manufactured trusses and typically run hi hat channel to screw drywall into.

I am really wondering about the comment above regarding too much mud. This just could be it.....

By board edge hanging, it doesnít happen often but we have had some cracks, which upon investigation, the hangers didnít properly screw the board up, or were sloppy in cutting. At that case we would typically cut a hole and resecure with furring/metal studs/whatever we have on site.

Re: Can We Talk Drywall Cracks?


To clarify, I think I am finding taped joints where there is not enough mud. Especially inside corners.

Thatís what I thought you meant, itís pretty hard to get too much on an inside corner. Iím sure it can be done but I usually see bare tape after the mudder sands.

Re: Can We Talk Drywall Cracks?


biggest cause in my opinion is sloppy framing and lack of bracing and proper nailers. i've probably framed at least 600 units and never really had callbacks for cracks or truss uplift, or screw pops even.
drywall should be glued to studs. and joints prefilled with durabond before tape.
