What does "glazing replacement" involve?

Glazing replacement specifically involves the process of removing existing glass and installing new glass. This procedure is commonly undertaken to address issues such as broken, cracked, or outdated glass panes that may not provide adequate insulation or aesthetic appeal. During this process, it's essential to ensure that the new glass is properly fitted into the frame and sealed to maintain energy efficiency and protect against moisture. This task requires precision and knowledge about various glass types and installation techniques, making it an essential aspect of glazing work.

The other options pertain to activities that do not encompass the fundamental concept of glazing replacement. Repainting glass surfaces, adding screens to windows, and polishing glass for clarity focus on maintenance and enhancement rather than the replacement of the glass itself. Thus, while they are related to window care, they do not fit the definition of glazing replacement as accurately as the removal and installation of glass do.
