How to Identify Nail Pops?

Nail pops are easy to spot because of their distinctive effect on the wall. Look for two distinct signs of nail pops: a small hole in your wall, or a bulging, cracked bump on your wall. Both are caused by nail pops. Also, it can be helpful to look for chipped paint on your drywall as this can also indicate movement behind your wall. Since walls are generally free of glaring imperfections, a hole or bump should be easy to notice for the average homeowner.
