Measure at selected locations.
Visible clues help guide the inspection, but moisture may be present behind an exterior that looks sound. Probe testing provides information about moisture at the tested locations and helps us assess the condition of the substrate.
Agree on the scope
We discuss the property, access and test locations, and obtain authorization for invasive testing.
Test behind the finish
Our sample report describes two ¼-inch holes at selected locations, passing through the stucco and water barrier to reach the substrate.
Seal and document
Test openings are sealed after testing. Locations, readings and observations are brought together in the report.
A reading needs context.
Readings are considered alongside the material, visible conditions, substrate assessment and other findings. A high reading does not by itself prove rot, and a lower reading does not rule out hidden issues elsewhere. The report applies to the conditions and locations inspected.
