The stucco itself is usually the last thing to show signs of failure. When water enters behind the concrete stucco and gets absorbed into the sheathing and framing, vast amounts of hidden damage can occur, leading to the eventual collapse of the supporting wooden framing.

Stucco problems come from the failure of the application and/or inadequate construction materials and techniques, including the lack of an adequate drainage system that allows the stucco to purge itself. Homes built between 1993 and 2006 have a much higher failure rate, estimated as high as 90%, due to incorrect building codes during that timeframe.

A comprehensive stucco test is carried out by moisture and resistance testing. Pairs of small holes, 3/16th”, are drilled into the stucco at specific locations on the house. These inconspicuous holes are small and are filled with a color matching caulk product when completed. A moisture probe is inserted through these holes and into the substrate and framing behind the stucco.

Our certified stucco testing specialists use state of the art Extech moisture meters with hammer probes. The Extech gives a much more accurate moisture reading than the typical cheaper probes used by many companies. The Extech reads moisture content from 1% to 100% versus a scale of 1-40 on inferior meters. This eliminates any guessing games on just how much moisture the substrate is holding.

The moisture content of the substrate indicates the health of the building envelope. A resistance probe determines the integrity of the substrate and the framing behind the stucco. This is accompanied with a visual inspection to determine the existence or lack of building details such as expansion joints, weep screeds, flashings and kickout diverters along with the existence and health of caulk joints and sealants around penetrations.
