Re: sheetrock nail pops
Nail pops can be cured with a light tap with a hammer to reset the nail, then install a screw along side the nail so that it binds and captures the nail. The two big reasons for pops is expansion and contraction of the materials or jarring vibration such as a slamming door.
Bulged seams are generally due to settling or movement of the structure. About the only thing you can do about a bulged seam is to peel it out and retape it. If the drywall itself is bulged, then the only cure is replacement of the affected areas.
