First-Rate Double-Hung Windows

Double-hung windows feature two vertical moveable sashes, offering ventilation through the bottom, top, or both. We install Infinity from Marvin double-hung windows crafted from fiberglass, which is eight times stronger than vinyl. In addition, our fiberglass windows won’t leak or crack, and they resist expanding and contracting during extreme weather changes.

Fiberglass is crafted to look like wood, offering a beautiful, traditional aesthetic while providing long-lasting protection for your home. And you won’t be limited in your design choices—our team will help you customize your new windows with numerous color, finish, hardware, and glass options to match your home’s architecture and color palette.
