Drywall Crack Patching

Drywall cracks come back when the underlying joint, tape, board movement, moisture issue, or stress around an opening was not fixed. Filling the visible line may hide it briefly, but the crack can return if the cause remains.

Douglas looks at where the crack sits and whether it follows a seam, corner, ceiling line, door, or window. A recurring crack often needs tape repair and wider finishing, not just another layer of filler.

Cracks around doors and windows should be repaired by addressing the stress point and feathering the patch beyond the visible line. Openings concentrate movement, so a narrow dab of compound often telegraphs after paint.

Douglas checks whether the crack is in drywall, tape, corner bead, or old plaster before choosing the repair. The finish may need to extend wider than the crack so light does not catch a hard edge around the opening.

Skim coating will not stop a drywall crack by itself if the joint or board is still moving. A skim coat can smooth the surface, but the crack should be reinforced or repaired first so it does not telegraph back through.

After the crack repair is sound, skim coating may help blend a rough wall or ceiling. Douglas separates the structural repair from the smoothing step so the surface is not only made prettier for a short time.
