A hole or dent in the wall is almost always impact damage: a doorknob swinging without a stop, furniture cornering too tightly, a picture anchor pulling out, or an elbow, toy, or moving-day mishap. The drywall itself has done exactly what it was asked to do until the moment it was hit harder than gypsum can handle. What decides the repair is not how ugly it looks but how big it is and whether the paper face is merely dented or fully broken through. Small dents and nail holes are filler jobs. Anything larger than about a fist usually needs a backing patch and re-texture to disappear.
A dry hole or dent is not urgent and does not get structurally worse sitting there, which makes it a good job to schedule on your own timing. It deserves quicker attention if sharp or crumbling edges are where children or pets brush past, if the hole has opened a gap into a wall cavity in a bathroom or exterior wall, or if the area around it feels soft, which points to moisture rather than simple impact damage.
The most common story. A door that opens too far drives its knob into the same spot repeatedly, and furniture pushed against a wall concentrates force on one small area. The result is a round dent or a clean punched hole, often with cracked paper around a crushed gypsum centre.
Heavy mirrors, shelves, and wall-mounted items hung on drywall anchors can tear out when the anchor was undersized, installed in crumbly board, or loaded beyond what plain drywall can hold. The hole is usually ragged, slightly larger than the anchor, and surrounded by lifted, bubbled paint.
Ladders, appliance dollies, sports gear, and furniture being carried through hallways all clip walls at corner height. These holes tend to be irregular, sometimes with a matching scuff or dent nearby, and the damage is usually confined to the one board rather than spreading along a seam.
Board that has absorbed moisture from a slow leak, a steamy bathroom, or an exterior wall problem loses its strength, so a modest bump that sound drywall would shrug off instead punches through. If the surrounding area feels spongy or stained, the hole is the symptom, not the whole problem.
| Job size | Typical estimate (CAD) |
|---|---|
| Simple fix — the straightforward version of this repair | $100–$220 |
| Major job — complex, hidden, or replacement-level work | $400–$2,000 |

Confident DIY covers nail holes, small dents, and holes up to roughly fist size using a self-adhesive patch, compound, patient sanding between thin coats, and primer before paint. Bring in a pro for large holes needing a cut-out patch with backing, damage on a ceiling, holes involving corners, or any wall with a texture you need matched invisibly. A pro is also the right call when the board around the damage is soft, because that repair starts with finding out why it went soft.
Only very small holes take filler alone. Compound shrinks as it dries and has almost no strength spanning a gap, so a fist-sized hole filled solid will crack, sag, and telegraph through the paint. Larger holes need a mesh patch or a piece of drywall set into the opening with backing, then compound feathered out over it in thin coats.
Usually because the patch was not primed, or the texture was not matched. Bare compound and joint tape absorb paint differently from the surrounding wall, a difference painters call flashing, and it shows most in side light. A coat of primer over the cured patch before the finish coat, plus a texture that roughly matches the wall, makes most repairs disappear.
Thin coats dry far more reliably than one thick coat, and each coat needs to be fully dry, not just surface-dry, before sanding and recoating, or the next layer softens the one beneath it. Follow the drying guidance on the product you are using, keep the coats thin, and resist sanding early, because damp compound tears and pills instead of smoothing.
Repairing the hole without stopping the impact guarantees a repeat. Fit a door stop, either a hinge-pin stop, a baseboard stop, or a small adhesive bumper where the knob lands, and check the door closer or hinges if the door swings with unusual force. Once the contact point is protected, a normal patch in that spot will last.
