Windows were inserted here and have begun to leak in heavy rain and wet conditions:

A full demolition of the area is needed to open up the envelope which has been compromised by the window installations (above):

Once the area is exposed then the windows undergo a full blue-skin sealing application, along with new edge dam flashing installation and tie in to existing paper envelope (above):

When new windows are installed on a stucco home a few things must be taken into consideration. Firstly, many installers use a process called window inserts. They will tell you they can put the window in flush without damage to your stucco, this is not 100 percent true. They may be able to insert the window without damaging the cement but the install process itself cuts the building envelope seal. Since stucco is porous, water can be absorbed by the cement and enter through this now cut paper. Windows on a stucco home must be sealed properly with blue-skin tar membrane and membrane primer. Secondly, insert windows cannot be properly flashed if the stucco around the window is not repaired. This can also lead to leaks. It is best that window installers work in conjunction with stucco professionals to insure the job is done right.

Why should you repair stucco after a new window installation?
