Drywall damage comes in three sizes. Small, which is nail pops, doorknob holes, and hairline cracks. Medium, which is a hole bigger than your hand or a crack that runs the length of a seam. And large, which is anything that's been wet.
Small damage is a straightforward patch: fill, tape if needed, sand, texture, prime. The skill is entirely in matching the texture so the repair disappears. Medium damage usually means cutting out a clean rectangle and installing a new piece of drywall, then taping and finishing the seams.
Water damage is different. Wet drywall loses its structure, grows mold, and never fully dries flat. If a section has been soaked, it needs to come out, and more importantly, the source of the water needs to be fixed first. Patching a wall under a leak just means patching it again.
Whatever the size, the goal is a wall where you can't find the repair under a raking light. Send us a photo and we'll tell you honestly which kind of job it is.
