Genex Window

Genex Window is a Michigan-based manufacturer and installer of custom-built vinyl replacement windows for residential homes. Unlike many window companies that resell mass-produced products, our windows are designed and built locally to fit each opening precisely—improving energy efficiency, durability, and long-term performance. We specialize in double-hung, casement, sliding, picture, bay and bow windows, as well as patio doors. Every unit is built to order using high-performance glass, reinforced vinyl frames, and premium hardware. Our team manages the entire process from in-home measurement through manufacturing and professional installation, ensuring tighter tolerances, cleaner installs, and consistent quality on every project.
