A Stucco inspection involves tests and analysis that may include the use of moisture reading and special equipment for use on interior and exterior surfaces to determine moisture levels.

The use of a probe to conduct the inspection involves penetration of the exterior surface by drilling (two ¼ inch holes at each inspection site) and probing, in order to contact the substrate, will result in observable puncture marks in the exterior surface. Inspector shall fill such probe hole using sealant that complies with ASTM-C920, will not paint but will attempt to match the sealant color to the adjacent wall color.

In the event it is deemed necessary by the Inspector, the inspector may conduct core sampling if required. A slightly larger hole will be drilled to determine the type and condition of the substrate as well as the WRB (Water Resistant Barrier).
