How Do I Repair a Small Hole or Crack in Drywall?

Root cause

Nail holes, screw holes, and small impact dents from a doorknob or furniture are purely cosmetic and don't affect the wall's structure at all — they just need to be filled, smoothed, and blended with the surrounding texture and paint.

30-second check

Confirm the hole is small (roughly under an inch) and there's no soft, crumbling, or water-stained drywall around it, which would point to a different cause.

Tools & materials

Lightweight spackle or joint compound, a putty knife, fine sandpaper, primer and matching paint.

Step-by-step

1. 1 Clean any loose debris from the hole.
2. 2 Apply spackle or joint compound with a putty knife, slightly overfilling the hole.
3. 3 Let it dry fully per the product's instructions, then sand smooth and flush with the surrounding wall.
4. 4 Apply a second thin coat if the first shrunk while drying, then sand again once dry.
5. 5 Prime the patch (bare compound absorbs paint differently than the surrounding wall) and paint to match.

Root cause

Holes in the roughly 2–6 inch range — from a doorknob punching through, a fixture that's been removed, or an access cut for plumbing or electrical work — are too large for simple spackle to bridge and need something to back the patch, or the compound will crack and fall through.

30-second check

Confirm the hole is a clean cosmetic opening rather than water-damaged or soft drywall around the edges, which points to a different underlying cause.

Tools & materials

A self-adhesive mesh patch or a small drywall offcut, joint compound, a taping knife, sandpaper, primer and paint.

Step-by-step

1. 1 Clean up any ragged edges around the hole with a utility knife.
2. 2 For holes up to about 6 inches, apply a self-adhesive mesh patch centered over the opening.
3. 3 Apply joint compound over the patch with a wide taping knife, feathering the edges well beyond the patch itself so the repair blends smoothly.
4. 4 Let dry, sand smooth, and apply a second thin coat as needed, sanding again once fully dry.
5. 5 Prime and paint to match, feathering the paint slightly beyond the patch area for the least visible seam.

Root cause

Small cracks, often at the corners of doors and windows or along a ceiling-wall joint, are a normal result of a house settling and materials expanding and contracting with the seasons. As long as they're thin (hairline) and not growing, they're cosmetic and simple to fix.

30-second check

Measure the crack's width — hairline cracks under about 1/16 inch that aren't actively growing are generally cosmetic. Note the location and whether it reappears after being patched, which would point elsewhere.

Tools & materials

Flexible spackle or paintable caulk for corner cracks, joint compound and mesh tape for wall cracks, sandpaper, paint.

Step-by-step

1. 1 For a crack along a corner or trim joint, apply a thin bead of paintable caulk and smooth with a wet finger.
2. 2 For a crack across open wall or ceiling, apply mesh tape over the crack first, then cover with joint compound, feathering the edges.
3. 3 Let dry, sand smooth, and apply a second coat if needed.
4. 4 Prime and paint to match.
5. 5 Note the date and location — if the same crack reopens within a few months, that's the signal to look further into the cause.

Root cause

A crack that keeps reopening in the same spot after being properly patched often points to ongoing structural movement rather than simple settling. Discoloration, softness, or a musty smell around damaged drywall points to water intrusion, which needs the actual leak addressed before the drywall itself is worth fixing. Holes larger than about a foot across also typically need new framing support, not just a patch.

30-second check

A patched crack has reopened in the same place, the drywall around the damage feels soft or spongy, you see discoloration or staining, or the hole is larger than roughly 12 inches across.

What a professional actually does

A contractor identifies whether a recurring crack points to foundation movement or another structural cause, locates and addresses any active water source before repairing the drywall, and installs proper backing framing for larger holes before patching and finishing.
