When inspecting windows for potential water leaks, where should inspectors pay careful attention?

In the context of inspecting windows for potential water leaks, focusing on the area around the header, sill, and below the window is crucial. These components are critical in the design of a window installation as they provide structural support and serve as key locations where water can enter if there is damage or poor sealing.

The header is the top part of the opening that supports the window, and if there is any deterioration or improper installation here, it can create pathways for water intrusion. The sill, located at the bottom, is particularly vulnerable, as water can pool here, especially if drainage systems are not functioning properly or if the sill is not sloped correctly to direct water away from the building. Additionally, the area below the window is important to check for signs of water damage, such as staining or mold, which could indicate that water has managed to penetrate through.

While inspecting the glass surface, the window frame materials, and the limitations and restrictions are all important aspects of a thorough inspection, they are secondary to the structural components that can lead to leaks. Understanding where and how water typically breaches window installations allows inspectors to focus their efforts on critical areas that directly affect the integrity of the building structure.
