Residents of Waterbury look to Renewal by Andersen for comprehensive window replacement services.

We provide seven distinct window styles, and each style comes with extensive customization possibilities. Select from rich colors, hardware styles, and grille patterns to build replacement windows that reflect your taste. Begin your home’s window replacement project with a free design consultation today.

Awning Windows

These windows are hinged at the top and open outward from the bottom, allowing for ventilation even during light rain. The design is ideal for adding airflow to a room without compromising on shelter.

Bay & Bow Windows

Bay windows are typically a fixed central window flanked by angled venting windows. Bow windows consist of multiple windows joined to create a gentle outward curve. Both styles extend the room slightly and provide expansive views and additional interior space.

Casement Windows

Casement windows are hinged on the side and swing outward like a door, providing maximum ventilation and unobstructed views. These replacement windows are known for ease of operation and tight sealing when closed. Waterbury homeowners enjoy our most energy-efficient window—the casement window!

Sliding Windows

Also known as gliding windows, these have sashes that slide horizontally. Sliding windows are a great option for spaces where an outswing window opening would be impractical.

Double Hung Windows

These windows have two sashes that move up and down, allowing for ventilation from the top, bottom, or both. Double hung windows are a classic window style and offer a traditional look with modern functionality.

Picture Windows

Picture windows are large, stationary windows designed to provide clear, unobstructed views while allowing ample natural light into a room. These replacement windows do not open, improving energy efficiency and comfort inside your home.

Specialty Windows

Specialty windows are custom windows available in a variety of shapes, sizes, and styles to fit unique spaces or architectural designs. These custom replacement windows can be combined with operational windows to create a distinctive look.
