This is the most common type of drywall repair. Small holes can be caused by a variety of factors, such as nail pops, doorknobs, and pictures. To patch a small hole, the damaged area is cut out and a new piece of drywall is inserted. The patch is then taped and sanded smooth.
Cracks in drywall can be caused by a variety of factors, such as foundation movement, shrinkage, and vibration. To repair a crack, the crack is widened and filled with a joint compound. The joint compound is then sanded smooth.
In some cases, it may be necessary to replace the entire drywall panel if the damage is too severe to be repaired. To replace a damaged panel, the old panel is removed and a new panel is installed. The new panel is then taped and sanded smooth.
