What is the first step in inspecting the M/I parts of a window during a reinspection?

The first step in inspecting the moving/interactive (M/I) parts of a window during a reinspection involves viewing the sashes outside the cavity. This is essential as it allows the inspector to visually assess the condition of the sashes, including any potential lead hazards, weathering, and operational functionality. By first examining the sashes from the exterior, the inspector can determine if they are properly sealed and functioning, and whether there are any exposed surfaces that could be a source of lead dust or chips, which are critical aspects when evaluating for lead safety.

Inspecting the decorative frame, ensuring the window is locked, and measuring the frame dimensions can be vital in their respective contexts but do not directly address the lead hazard assessment and functional integrity of the window itself, making them secondary considerations to the condition of the sashes. Observing the sashes from the exterior provides immediate insight into any issues that may pose risk, which is why it is prioritized in the inspection process.
