Window installers are professionals who specialize in the installation of windows in residential and commercial buildings. They ensure that windows are fitted correctly, providing energy efficiency, security, and aesthetic appeal. Their work often involves measuring openings, removing old windows, and sealing new ones to prevent drafts and water leaks. In addition to installation, window installers may also offer services such as repairs and replacements. They typically work with various types of windows, including double-hung, casement, and sliding windows. Proper installation is crucial for maximizing the lifespan and performance of windows, making skilled installers essential for any construction or renovation project.
