Window replacement involves removing old or damaged windows and installing new ones to improve energy efficiency, aesthetics, and security. This process can enhance the overall appearance of a home and reduce heating and cooling costs by minimizing drafts and heat loss. Homeowners may choose various types of windows, such as double-hung, casement, or sliding windows, depending on their needs and preferences. Professional installation is often recommended to ensure proper sealing and fit, which can further enhance the window's performance and longevity.
