A professional technician is carefully replacing a glass unit in a modern window frame within a residential setting. The technician, dressed in a clean and professional uniform, is using specialized tools to remove the old glass unit and install the new one with precision. The window frame is contemporary, and the surrounding area is well-organized, clean, and brightly lit, highlighting the quality and attention to detail of the service. The image should convey a strong sense of professionalism, expertise, and reliability, making it ideal for promoting glass replacement services in an online store specializing in window maintenance and repair.
