This chimney showed signs of recent drywall repair. When repairs have been made just prior to the inspection the question in the buyers mind is has the condition been fixed? In a standard inspection performed to minimum standards the question often cannot be answered. Water seeks the path of least resistance and can leak even where problems are not visually apparent. In this situation I used a garden hose with a sprayer designed to simulate a typical rainfall. Within a few minutes leakage was obvious. Moisture meters were ineffective in this circumstance because dry weather conditions prevailed prior to the inspection. Recent repairs also concealed any evidence of problems.
