Windows – Single Hung Windows
Single hung windows feature a fixed upper sash and a movable lower sash, offering simple operation, energy efficiency, and a classic look ideal for many home styles.
Single hung windows are a timeless and practical choice for homeowners who value durability, efficiency, and cost-effective design. Featuring a fixed upper sash and a movable lower sash, these windows provide controlled ventilation while maintaining excellent insulation against drafts and moisture.
At Milton Windows And Doors Services Inc., we provide professional single hung window repair, replacement, and installation services for residential properties. Whether your windows are difficult to open, allowing air leaks, showing signs of aging, or no longer performing efficiently, our skilled technicians deliver dependable solutions that enhance comfort, security, and long-term value.
A single hung window consists of two vertically aligned sashes. The upper sash remains stationary, while the lower sash slides upward to allow fresh air into the home. This simple yet effective design minimizes air infiltration, improves energy efficiency, and requires less maintenance than many other window styles.
Single hung windows suit a wide range of spaces, including bedrooms, living rooms, kitchens, and basements, and their clean appearance blends seamlessly with traditional, contemporary, and transitional home designs.

Smooth vertical sliding system for easy ventilation
Tilt-in lower sash for convenient indoor cleaning

Single hung windows are ideal for homeowners seeking energy efficiency, long-lasting performance, and excellent value.
This installation method removes the entire window, including the frame. It allows for inspection and correction of structural issues such as moisture damage or wood rot before installing a new, fully sealed window system for maximum performance.
Retrofit installation replaces only the glass and sash while keeping the existing frame intact. This option is faster and more cost-effective when the current frame is in good condition and still structurally sound.
