A stucco contractor can determine whether your stucco should be repaired or replaced based on the scope of the damage. It's difficult to detect the extent of the damage in stucco on your own, so it’s best to have a professional inspect your home and decide if it's salvageable.
Professionals can typically repair horizontal cracking or small damaged areas. However, if the stucco was installed incorrectly or if there is widespread water or mold damage, your stucco siding will need to be replaced to prevent more problems.
