During reinspection, what must be ensured about the sashes once they have been replaced?

Ensuring that the sashes function properly after they have been replaced is crucial for several reasons. Functionality is key to maintaining the integrity of a window system and plays a significant role in safety and accessibility. If sashes do not operate as intended, it can lead to issues such as trapped moisture, potential security vulnerabilities, and difficulty in escaping in case of an emergency.

Additionally, properly functioning sashes contribute to the overall energy efficiency of a building. Streamlined operations help in closing the window securely, thereby reducing drafts and preventing heat loss.

While other options touch on important aspects of window maintenance, such as painting or color matching, the primary focus during reinspection centers on ensuring functionality to guarantee that the replacement meets both safety standards and operational efficacy.
