Water leaking through stucco walls
So you can imagine how surprised we were to find a stucco wall leak when we were scheduled to test the roof and windows. Because of our test of the roof, secondary water running down the wall made its way into the building. Likewise, our window test provided the exact same results. Water into the building from stucco leaks.
Naturally, our next step was to isolate the wall in various locations and perform isolated stucco wall testing. Obviously, our goal is to source water leaking through stucco walls. Hence, the need for isolation. We selected random areas to be rain leak and stucco leak tested.
As seen in these results, water penetrated the stucco wall in multiple locations throughout. In the end, our client decided to have the entire house re-stuccoed.
