Retrofit or replacement windows refer to the process of installing energy-efficient glass into an already existing window frame without disrupting the surrounding framing, drywall, siding, or trim. These types of windows must match the size of the current frame, unlike new construction windows that come in various sizes and shapes.

​

One significant benefit of replacement windows is their versatility, as they can work with almost any existing window, making the installation process easy. However, there are situations where the current window frame may not be correctly aligned with the wall or has become distorted over time, requiring a more complicated installation process. Retrofit windows offer an excellent solution by allowing you to install new, attractive windows in your home without having to modify the underlying structural window frame that your current windows occupy.
