It is the nature of stucco to experience some
cracking. Small stucco cracks are normal and do
not require any maintenance or repair. If a
crack exceeds 1/8 inch in width then the crack
should be repaired. Repairing of stucco cracks
is made by adding a small amount of stucco to
the crack. Do not put caulking into cracks. If
you experience cracks that are over 1/8 inch in
width, you should contact your builder so that
the proper resolution can be determined.
