Drywall errors

Hello,

Had a "professional" drywall company do the interior walls and ceilings.

Two months later, portions of the drywall has "split" along the seams in two places for about 3/4 the length of the rooms.....Not real noticeable but if you stare at the ceiling its quite evident.....Three different rooms......13x25 (2) and the other is 20x35.....

The 20X35 room has drywall with orange peel finish on the ceilings, and the trusses run 90 degrees to the seam splits......trusses supported on exterior wall with H10s on both sides, and truss is supported on the opposing wall. The adjoining rooms (12 X15) and hallway are free from problems...It was coated with primer and painted with ceiling paint.

The drywall fellow says he doen't know what happened but is willing to "make it right"......

Any theories on what might have caused the splits? Kind of nervous that after he fixes it, there are continuing problems either with the "fix" or other places start doing the same.....

 

Can not see what your looking at without some pictures.
New drywall?
Sure there was enough screws?

 

Pictures would be nice. I can't imagine a split along the entire edge of the sheetrock unless they used inferior tape, no tape, or just didn't bed it properly. Taping is supposed to keep cracks from happening.

 

Do you know if he used paper tape or the mesh [sticky] tape? Paper tape is better. When using sticky tape you need to coat over it with a setting compound like Durabond or EasySand.

 

If the split is in the open field of drywall then I would most likely expect mesh tape without using a setting type of mud (durabond).

If the split is close to the wall to hallway, then it could more likely represent an issues related to truss uplift. The "pro" should be aware of the issues regarding both of those potential causes.
