Not every hole is fixed the same way. How we repair small dings, door-knob holes, big cut-outs and water damage so the patch disappears.
A good drywall repair is one you cannot find afterwards. That comes down to three things: using the right repair for the size of the damage, matching the wall texture, and painting it properly. Here is how we approach the most common problems.
Small dings and nail holes
Picture-hanging holes and small dents just need lightweight spackle, a light sanding and primer before paint. Skipping the primer is why many touch-ups show as a dull spot.
Nail pops
Those small round bumps in a row are fasteners backing out as the framing moves. Covering them with mud only works for a few months. We set a new drywall screw just beside each one, then recess and refinish the old one.
Door-knob sized holes
Holes up to a few inches get a backed patch so the repair has something solid behind it, then two or three thin coats of joint compound feathered out wide so there is no visible bump.
Large holes and cut-outs
For bigger damage, we cut the hole back to a clean rectangle, add backing or open it up to the studs, screw in a new piece of drywall, tape the seams and finish it like new construction.
Water damage
Stains and soft, sagging drywall on a ceiling mean water got in somewhere. The first step is always to find and fix the leak — a roof, an A/C drain line, a bathroom upstairs. Drywall that stayed wet should be cut out, not painted over: the EPA notes mold can start growing within 24 to 48 hours of a leak, and in South Florida humidity it does not need much encouragement.
Paint: touch-up or the whole wall?
Even with the exact same paint, a small touch-up can show because older paint fades and the sheen reads differently. On flat and matte finishes a careful touch-up often blends in. On eggshell or satin walls, painting corner to corner is usually the way to make the repair invisible.
