Patch-and-Repair vs Full Reskim or Replacement

Spot patching is the right move for localized, defined damage — a hole, a crack, a small water-stained area — on a wall that is otherwise sound. It is the cheapest and least disruptive option, and a skilled finisher can make the patch vanish into the surrounding texture. This covers the vast majority of everyday drywall jobs: the doorknob hole, the settling crack over a doorway, the dent from moving furniture. There is no reason to redo a whole wall when the rest of it is fine.

Reskimming — applying a thin skim coat over an entire wall or ceiling — is the answer when the surface has widespread minor flaws: lots of small cracks, a dated heavy texture you want gone, peeling paint texture, or a patchwork of old repairs that never quite matched. Rather than chasing dozens of spots, the finisher levels and smooths the whole surface for a uniform, like-new result. It costs more than spot patching but far less than tearing out and replacing, and it is the smart middle path for walls that are intact but ugly.

Cutting out and replacing drywall is reserved for damage that goes beyond the surface: extensive water damage, mold, sagging or crumbling board, or major holes where patching would be more work than starting fresh. It is also the path when you are opening walls for other work anyway. Replacement is the most involved and expensive option, but for compromised board it is the only one that truly solves the problem — patching over mold or saturated drywall just buries it. A finisher will tell you honestly when the damage has crossed that line.
