Project Information
This commercial building was experiencing water staining in the ceilings and walls in their commercial spaces. After performing a water test and inspections on the building, ESI concluded that the window lintels lacked proper flashing and end dams.
Flashing masonry openings are a wall system’s primary defenses to channel the moisture’s exit. In portions of the wall that do not contain openings, this water will stay in the masonry and be absorbed by the masonry materials of the wall system until it evaporates.
At windows, however, the masonry wall is interrupted. Water traveling down within the wall will flow into the interior or onto the head of the window. This can cause internal leakage and damage.
Installing a flashing system that extends from the backup wall to the exterior wythe will help prevent this.
