If the anchor hole sits too close to the drywall edge, treat it as a fragile repair that needs reinforcement rather than a quick anchor swap.

Start by assessing how close the hole is to the edge and how much drywall remains intact, then remove any loose paper or gypsum with a utility knife so the repair surface is clean. If the remaining drywall edge is less than one inch from the hole, do not try to use a standard expansion anchor there; instead cut a small rectangular opening around the damage to expose the stud bay when possible and add backing. For repairs where cutting out is not possible, apply a self-adhesive fiberglass mesh patch centered over the hole, press it smooth, then embed three thin layers of joint compound, letting each layer dry fully and sanding lightly between layers for a flat feathered finish. When additional strength is needed behind the drywall, slide a thin scrap of plywood or a metal mending plate between the studs and screw a pair of long screws through the drywall and backing to clamp it, then cover the repaired area with mesh and compound. For load bearing fixtures consider switching to toggle or strap-style anchors that spread load across a larger area and always orient screws so they pull into stronger material when possible. Finally prime and paint the surface, and when reinstalling the fixture use a wide washer or a mounting plate to distribute force away from the repaired edge.

Common mistakes start with trying to drive a new expansion anchor too close to the edge, which simply tears the weakened paper and gypsum; the fix is to expand the repair area and add backing or use a load spreading anchor. Another error is skimping on mesh and compound layers then rushing the reinstall, which leaves a repair that fails under load; let each compound layer dry fully and sand between layers for proper adhesion. People also assume a toggle or strap anchor is always the answer without checking behind the wall, which can lead to hitting pipes or wiring; locate obstructions first and, if you cannot, open a slightly larger access to inspect and add backing if needed.
