You could replace popped nails and the damaged walls they came from, but this doesn’t offer a solution to the larger problem – foundation damage. Simply replacing nails might make the house look better for a time, but eventually, foundation settlement is going to cause the same problem to occur again. The best step you can take to address drywall nail pops is to contact a professional foundation repair service like Tar Heel. With a professional solution, you can prevent foundation problems from arising in the future, especially with pier systems that support your home independently of soil.
